How to Treat Subsidence

There is nothing more troubling for a homeowner than the discovery of subsidence, especially if it is severe. After all, this suggests that the foundations of a property are no long able to support its weight effectively. In layman’s terms, subsidence is ‘the movement of soil or the gradual sinking of land’ which puts pressure on the foundations of a building and causes it to become unstable. Luckily, it can be prevented and rectified with the expertise of a licenced professional. Read on to find out how subsidence is treated…

Underpinning

In serious cases, the most effective way to treat subsidence is through a foundational support known as underpinning. This involves extending the depth of existing foundations or providing a more supportive soil layer so that the weight of a property is spread evenly. With this said, underpinning can be expensive so homeowners should try to rectify subsidence before it becomes severe enough to require foundational intervention.

Remove Trees

Although subsidence is often caused by the movement of weak soil, tree roots can also damage the foundations of a property. After all, they can extend 5m in all directions which means that a tree located within close proximity to a property will suck up all the moisture from the soil that surrounds its foundations. Over time, the soil will begin to shrink and this will lead to subsidence. An easy way to curb subsidence is to have a troublesome tree removed.

Repair Drains/Pipes

All of the drains and pipes within a property are designed in order to transport water deep beneath the ground so that it does not cause any issues. After all, subsidence can also be caused by an active leak because moisture saturated soil will become too soft and weak, allowing the foundations above to move. This is even more problematic when it comes to sandy soil because this can be easily washed away. In order to rectify minor subsidence caused by leaks, it is important to repair any broken drains or pipework.

Here at Rhino Piling, we ensure that every member of our team has the qualifications required to provide the very best underpinning solutions possible. After all, subsidence is no laughing matter which means that both property owners and licenced foundational experts should never treat it as such.

Does Underpinning Affect Home Insurance Cover?

Here at Rhino Piling, we are constantly reinforcing the importance of high-quality foundations and why homeowners should invest in their property if they notice the signs of subsidence. With this said, we have noticed some apprehension amongst clients in regards to their eligibility for home insurance. After all, these companies tend to scrutinize the foundations of a property fairly closely. Read on as we go over everything there is to know about home insurance and underpinning…

What is underpinning?

In layman’s terms, underpinning is the process of providing additional support and strength to the foundations of a property. It most circumstances, it is carried out on existing buildings as a direct result of subsidence, a problem that arises from the partial collapse of a property due to weak foundations or the movement of soil. With this said, underpinning can also be implemented for additional buildings such as garages or conservatories.

Does home insurance cover underpinning?

Many insurance companies like to implement clauses that will catch people off-guard and this means that it is important to look at the terms and conditions of a contract closely.   After all, home insurance may cover underpinning costs depending on the reason why the work is required, such as in cases like subsidence. On the other hand, underpinning that is being carried out in preparation for a home extension must be paid for out of the property owners personal funds.

Will underpinning increase insurance premiums?

Insurance is put in place as an assessment of risk and this means that potential insurers often want to know if they are exposing themselves by choosing to provide cover for a particular property. It is no secret that underpinned homes are much riskier than homes that still retain their original foundation because it suggests that the property may not be structurally safe.  With this said, many home insurances companies will still provide cover and the premiums should be relatively unaffected depending on the severity of the subsidence or as long as there has been no recent movement.

Underpinning is the perfect alternative to traditional piling in situations where headroom is limited and vibrations are too dangerous. After all, subsidence should never be allowed to fester once it has been discovered.

The Lowdown on Pile Drivers

Here at Rhino Piling, we are proud to say that our team are committed to each and every project we are entrusted with. After all, the foundations are the bread and butter of a property which is why they should be installed by licensed and experienced contractors in order to ensure that they meet safety regulations and have the ability to withstand the test of time. The machinery that is used in order to install piling foundations is often bulky and complex, however we’ve have decided to simplify the jargon for our readers. Read on as we go over everything there is to know about pile drivers…

What are pile foundations?

The foundations of a property provide its structure with additional support and ensures that its load is spread equally so that certain points aren’t bearing more weight than they can withstand. Piling is a type of deep foundational method that uses steel, concrete or wooden columns in order to bypass the soft soil on the surface and reinforce the weight of a building to the more robust soil below it.

Different Types of Pile Drivers

Since piles are made from heavy materials, they must be installed through the use of specialist machinery like pile drivers in order to force them to bypass the weak surface soil in an accurate manner. They do this by placing a weight between the guides to allow for vertical movement; the weight is then raised above the pile using hydraulic, steam, diesel or manual labour and then dropped at a suitable height in order to drive it into the ground. Interestingly, there are several different types of pile drivers that can be used depending on the needs of a project and the method as to which the weight is lifted above the pile. With this said, the most prevalent varieties include the diesel hammer, hydraulic hammer and hydraulic press-in hammer.

For industrial applications, it is also possible to implement a type of pile driver known as a piling rig. This large piece of machinery is often used for foundational engineering during municipal construction, slope protection, and industrial and civil building foundations. Piling rigs tend to operate through the use of hydraulic pilot controls and have a load sensor which makes them incredibly easy to control and therefore suitable for specialised circumstances.

Piling foundations are crafted from slender, columnar elements that are typically crafted from steel or reinforced concrete. As a result, specialised machinery like pile drivers are required in order to install the piles with accuracy and ensure that the deep foundations come into contact with the solid soil located deep within the earth.

How Does Mini Piling Work?

The foundations of a property are put in place in order to stabilise the structure and ensure that its weight is spread evenly as a lack of support will wreak havoc several decades down the line. In fact, there are a variety of different approaches that property owners can take such as traditional piles, groundworks or even mini-piling. Read on as the Rhino Piling team explain how mini-piling works and why it is such an effective method…

Mini-piling is a type of foundational solution that can be implemented when there is a lack of headroom, a restriction on the amount of space that is available or when the first layer of soil is too unstable to support traditional piles. It is no secret that regular piling is the superior option, however mini-piling is an incredibly effective alternative in these situations.

During the process, steel casings are driven or screwed into the ground using specialist machinery and then filled with concrete or grout. It is incredibly similar to traditional piling; however, the soil is given additional support from the external shaft casing which is important in situations where the soil is too weak to support the mini-pile on its own.

There are several different types of mini-piling that contractors can choose from in order to suit a particular project. For example, sectional auger mini-piling involves installing the supportive shafts in segments in order to account for a lack of headroom or space. Interestingly, these supports can be left in place or removed after the concrete has been poured in depending the stability of the soil.

Here at Rhino Piling, we want to provide our clients with a foundation that can withstand the test of time. After all, it is a time consuming and costly endeavour which means that property owners should never have to invest in additional projects in order to rectify sloppy or lazy work. Our team are highly trained in the field of foundational approaches and that is why Rhino Piling is considered the best piling Manchester has to offer.

Frequently Asked Underpinning Questions

Here at Rhino Piling, we know how much damage subsidence can cause to a property, especially when it is left to fester and is not rectified as soon as it is discovered. Our experts are trained in order to assess the foundations of a building and find an appropriate solution that will benefit the client and the structure simultaneously. Underpinning is a foundational method that can be used in order to provide additional support to properties that have been affected by subtle or severe subsidence. Read on as we go over some of the FAQ’s that customers tend to have about underpinning…

Why does underpinning need to be implemented?

In the majority of cases, underpinning is used in order to secure a property that has been affected by subsidence. This is the sudden or gradual sinking of a certain area of a building due to the movement of the soil underneath and it can be recognised by the presence of diagonal cracks in brickwork, gaps between window or door frames, and the gradual leaning of a property to one side. Underpinning reinforces the damage caused by subsidence in order to secure the structure from within.

How much does underpinning cost?

It is difficult to determine how much it will cost to implement underpinning foundations as the amount of work that needs to take place tends to depend on the extent of the damage that has been caused by subsidence. In addition to this, foundational experts must also take the location of the property into consideration and whether or not access is restricted. Luckily, underpinning is an investment for the future and often only needs to be implemented once in a lifetime.

Does underpinning affect home insurance?

Many homeowners are concerned that investing in underpinning methods can affect their quote with a home insurance provider. After all, high-risk properties often come with a higher premium. Although underpinning can reduce the risk of subsidence, it does not guarantee that the problem will be completely eradicated. As a result, it is recommended that homeowner’s shop around for insurance in order to find the best price and prevent insurance companies from taking advantage of their situation.

It is important that property owners are able to recognise the early signs of subsidence so that they can take the appropriate measures to rectify the problem before it becomes too serious to solve. After all, an entire property can collapse if subsidence is allowed to progress past a certain point. Luckily, underpinning replaces soft soil with stronger materials and creates a framework underneath an existing foundation in order to stabilise a property.

The Lowdown on Restricted Access Piling

Piling is used in order to provide a property with a foundation and ensure that the overall structure is secure. As a result, it often requires the use of large, heavy machinery in order to install the piles deep within the ground, however there are certain situations where this is not feasible. Luckily, industry experts have prepared for this inevitability, and restricted access piling is a piling approach that can be carried out in specialist circumstances. Read on as we go over everything there is to know about restricted access piling…

Where is restricted access piling carried out?

There are many situations when the traditional machinery used to install piles cannot be utilised effectively, and this is where restricted access piling comes into play. For example, this method can be used when access and headroom is limited, when noise and vibration must be kept to minimum, in locations where weight surcharges apply, at archaeological sensitive sites, or when underpinning is being implemented from within an existing building or structure.

How is restricted access piling installed?

A casing with a diameter of 100-1080mm is placed into the ground at the required depth using a pre-determined drilling technique. After this, reinforced steel is inserted into the casing in order to provide addition support to the pile, and then concrete grout is pumped into the structure. Depending on the circumstances, the casing with either extended the full depth of the pile or it will stop short of the desired depth and the steel reinforcement will provide the necessary additional support.

What are the benefits of restricted access piling?

Restricted access piling is an excellent way to secure the structure of a property that has been deemed unsuitable for traditional piling methods. For example, it can be successful utilised in existing buildings and tunnels, in all ground/soil conditions, and areas where excessive vibrations may put the structure of nearby properties at risk. In addition to this, restricted access piling can also be carried out in a cost-effective and eco-friendly format.

Here at Rhino Piling, we know how important a foundation is for the longevity of a building and that is why our team work around the clock in order to devise the most effective piling solutions possible. In fact, we specialise in everything from underpinning and mini-piling to new-build foundations and restricted access piling.

3 Reasons Why a Building Needs a Foundation

The ground that we walk on answers to nobody but nature and this means that our man-made buildings are constantly at risk of deterioration from forces that we cannot see, hear or control. As a result, it is vital that every structure, from residential flats to skyscrapers, is reinforced with a high-quality foundation. Read on as the experts at Rhino Piling go over 3 reasons why a building should always have a foundation in place…

Stability

The weight of a small house and a large skyscraper may differ considerably from one another; however, it is essential that their individual loads are supported by a foundation in order to provide stability to the overall structure of the building. After all, a lack of stability leaves a property vulnerable to damage over its lifespan and means that certain pressure points of a structure will have to bear more weight than others because the load is not spread equally.

Prevents Subsidence

The movement of soil is thought to be the number one cause of foundational issues in existing properties. In fact, poorly installed foundations can do just as much damage as a lack of foundations. Piles are installed deep within the earth which allows the weight of a structure to bypass the weak soil and reinforce it onto the harder, more robust soil that is found deep within the earth. As a result, movement or moisture changes to the soil directly underneath a property is less likely to cause subsidence, the gradual sinking of a property or structure.

Longevity

There are buildings in the UK that were built hundreds of years ago and this means that a well-designed structure can last a lifetime with the very best team. With this said, the longevity guarantee of a building is only as good as its foundation because a lack of support will lead to early deterioration and this will, in turn, result in expensive and devastating consequences in the future.

Here at Rhino Piling, our team are trained to provide each and every customer with a service to remember. After all, a foundation should only be a once in a lifetime investment when it is done correctly and professionally. With this said, many of our projects involve the implementation of foundations to an existing building!

The effect heat waves can have on your home’s foundations

Subsidence is a problem all homeowners should be wary of as it can end up causing expensive damage and can even cause large portions of your home to collapse, making it unliveable for the foreseeable future.

 

With British weather being so unpredictable; varying from heavy rain to scorching months of summer heat, homeowners also need to know what weather is capable of doing to their home’s foundations in order to spot damage before it gets worse.

 

Subsidence occurs when there is a shift in the ground underneath and surrounding the property’s foundations. This causes the building to sink or collapse. Hot weather affects the soil, causing it to shrink, as prolonged hot weather draws more and more moisture out from the earth. Clay soil is much more at risk from shrinkage than other soil types, but prolonged hot weather can cause every soil type to shrink enough that it can pull away from the foundations and cause subsidence.

 

If a property is surrounded by lots of trees and other foliage this can exacerbate the problem further as the roots of these will draw even more water out of the soil.

 

How to spot subsidence

 

Regardless of how it happens, the signs of subsidence are often the same. The most notable sign is that of diagonal cracks appearing inside the home, usually next to a door or a window. These cracks are generally wider at the bottom and get narrower as they get higher. Some of these cracks can be so bad they can be seen from the outside as well as the inside of the house.

 

If the crack appears underneath wallpaper it wont be as noticeable, it may manifest itself as a wrinkling of the wallpaper. Some cracks are known to make noises as they develop, so if you hear a large cracking or banging sound, investigate immediately and contact an engineer.

The differences in equipment between commercial and residential projects

Whilst piling and groundworks do share some similarities across residential and commercial construction, there are also some notable differences that piling companies like us have to take into account before approaching each job.

 

These differences may seem like small changes, but if they are not heeded, then piling may be deemed unsuitable and even dangerous to be built upon. Understanding the differences is also important for clients so that they can select the right construction specialist for the project they have in mind.

 

Size Matters In Construction

 

The most easily recognisable difference between commercial and residential piling work is the equipment involved. The scale of the project is usually widely different; commercial jobs are usually large in scale and require bigger high-powered machinery, specialist equipment and even cranes to transport machinery and materials into place; residential properties require much smaller equipment that can be operated by single individuals and can be moved into place quickly and easily with little disturbance.

 

Most residential piling takes place on extensions to current buildings, which means access to the property is often limited. Large, cumbersome machinery, the likes of which you find on a commercial project, would be impossible to move into place. In order to be able to move machinery in to place with limited access, residential piling machinery is often constructed under specific guidelines in order to fit easily through tight spaces and is able to be set up with limited room available.

 

As machinery and equipment becomes bigger it also becomes more dangerous to operate and also requires more extensive training in order to operate. Without specially trained personnel commercial machinery cannot be operated. With residential equipment, the training is much less specialised.

 

The size of a project influences the equipment requirements we have to take into consideration for all piling in Cheshire.

 

 

The Benefits of Groundworks

The foundations of a property can be implemented in a variety of different ways as it is important to remember that piling is not the most appropriate solution for every project. In fact, groundworks are reinforced steel cages that are installed in order to aid our underpinning or piling methods and ensure that the finished foundation is stable and secure. Read on as we go over three benefits of investing in groundworks…

Overall Singular Strength

Although they may appear complicated, groundworks are actually a rather simple foundational solution. After all, they create a link between each pile that is installed into the ground and this creates an overall singular platform of strength and therefore ensures that a structure is as stable as it can possibly be when the additional weight of the brickwork is added on top of it.

Affordability

Since a high-quality foundation can last a considerable number of years, many property owners prefer to see groundworks as an investment for the future. With this said, it is also one of the most cost-effective foundational methods because the steel cage is relatively simple to construct which means that less time and money is spent on manual labour.

Durability

By creating a singular strength, groundworks provide a foundation with more durability than traditional piling would alone. After all, piles may transfer the weight of a structure to the soil deep within the earth, however these multiple points of strength will eventually require intervention. On the other hand, groundworks can increase the lifespan of piles by ensuring that this weight is spread equally over the entire foundation.

Here at Rhino Piling, our specialists are well versed in a wide range of different foundational methods. After all, we may be known for the best piling in Manchester, but that doesn’t mean that we are willing to sacrifice our groundworks and underpinning skills in the process.
