When Is Underpinning Required?

At Clifton Hill and Montpelier Builders & Construction, underpinning and foundation works are part of our core competencies. There are a number of reasons why your property may require underpinning.
Some examples of why underpinning might be necessary are:

  • The original foundation is no longer suitable or strong enough.
  • You need to add floors, either above or below ground, to the structure. As the new construction puts pressure on the structure, it is important that the foundation is strong enough to withstand this new load.
  • The condition of the floor structure under the foundation may have suffered unwanted changes.
  • Groundworks from neighbouring structures can endanger the foundations of your structure.
  • When converting or renovating existing buildings, an underpinning may be required to stabilize and strengthen the foundations.
  • Stabilisation of foundations that are affected by erosion, mining, and vibration damage.

At Clifton Hill and Montpelier Builders & Construction, our underpinning solutions help to manage and reduce foundation issues to the barest minimum.

Underpinning Services We Provide

Clifton Hill and Montpelier Builders & Construction offers homeowners in Brighton, East Sussex a full range of professional underpinning services. Our entire range of services includes:

Conventional Mass Concrete Underpinning

This underpinning method strengthens the foundation of an existing structure by digging boxes manually underneath and pouring concrete one after the other in a strategic order. The result is a foundation that is built under the existing foundation. This method is generally used when the existing foundation is shallow but up to 15 metres deep.

Because of its low cost and suitability for underpinnings with shallow depth and high foundation loads, this is the most common method of underpinning.

Pile And Beam Underpinning

The pile and beam method is a further development of the mass concrete method where a reinforced concrete beam is built either above, below or in place of the current foundation.

This foundation redirects the weight of the structure to several concrete masses placed at certain strategic positions, the placement and size depend on the soil conditions and the size of the property.

The advantages of underpinning with piles and beams are:

  • Suitable for areas with restricted access;
  • Faster than conventional underpinning;
  • High resilience;
  • Less disruption, less damage, and can be done quickly.

Needle Beam Underpinning

Needle beam underpinning stabilises existing foundations by installing concrete needle carriers that are supported by concrete mini piles. The design determines the distance between the needles and the mini pile’s diameter.

Concrete mini-piles can either be cast on-site (wet concrete with steel reinforcement is used here) or cast in advance (manufactured outside the construction site and supplied as a dry solid concrete component).

A small hole or pocket is dug underground and directly over the existing foundation. Concrete mini piles are then installed in the ground next to the newly built hole.

Cantilever And Beam Underpinning

Similar to piles and beams, this technique is used to lay the piles in the direction of pressure and tension. All work is carried out outside the property, which saves considerable costs in removing interior floors and fittings.This method can be carried out using conventional piles, and screw piles in combination with Helibeam masonry reinforcement.

Clifton Hill and Montpelier Builders & Construction offers a wide range of techniques for solving foundation and weight problems including cantilever and beams underpinning.

Thanks to our specialist knowledge and technical skills, we can offer you the most economical and suitable solution for your project. 

Mini Piled Underpinning

With mini piled underpinning, the load of the structure and the foundation is transferred to stable ground at the depth of the floor. This depth usually exceeds 5 metres. The constructed piles are made of steel and have a diameter of 15 cm to 30 cm. The piles are driven into boreholes so that they rest on a stable surface. Some piles can be built to reach up to 15 meters underground.

Mini piled underpinning is a versatile method that is typically used when soil conditions are uncertain, access is restricted, and the environmental impact is significant.

Clifton Hill and Montpelier Builders & Construction offers various cost-effective solutions for mini piled underpinning. We provide a survey service, and our panel of professionally trained engineers can offer detailed, top-value permanent solutions.

Internal Piled Raft Underpinning System

Internal Piled Raft Underpinning System supports single room walls or entire buildings. Using low-vibration pile equipment, mini piles are mounted internally and the piles are integrated into a series of needles which are then set in a new floor slab of reinforced concrete to provide structural support to the building.

At Clifton Hill and Montpelier Builders & Constructions, we can design and implement an effective Internal Piled Raft Underpinning System for your Brighton property. Our raft underpinning solution is guaranteed to optimise the structural integrity of your building permanently.

Pier And Beam Underpinning

At Clifton Hill and Montpelier Builders & Construction, our pier and beam underpinning solutions are ideal for renovation work on buildings with a crawlspace and good outside access. This method was developed to cover the limitation of the slab concrete method. It is suitable for a relatively deep primer and is suitable for all soil conditions.

Our experienced and skilled engineers design economical pier and beam underpinning plans when the soil or site conditions consider this as an appropriate stabilisation method. Before proposing, developing, and estimating a practical and effective solution, Artista civil engineers will consider all aspects of foundation subsidence problem.

Expanding Resin Injection

The injection of expanding resin is a new and innovative method that increases the strength and stability of the floor. This is achieved by injecting a mixture of hardener resin into the ground or floor around and under the house. The mixture compacts the soil, which can effectively support the weight of the house.

Clifton Hill and Montpelier Builders & Construction offers a wide range of effective and economical solutions for all types of subsidence problems. We offer a range of primer and foundation repair systems, including injection of expanding resin, which requires very careful planning and execution.

Structural Engineering Solutions

If a building has been damaged by foundation movements and has to be underpinned, structural repairs or reinforcement work on the structure may also have to be carried out. Such work should be planned and carried out by a structural engineer or a specialist company that handles structural repairs.

At Clifton Hill and Montpelier Builders & Construction we have a team of experienced structural engineers who can repair your damaged structures.

Building Codes

If you want to fully or partially support the foundations of your building, you may need to seek approval from the relevant authorities.

The regulations explicitly define this as “construction work” and appropriate measures must be taken to ensure that the foundation stabilizes the movement of the building. The homeowners are legally responsible for ensuring that all construction or remodelling work complies with building standards. You can delegate this responsibility to Clifton Hill and Montpelier Builders & Construction before we start working.

We make sure that your house meets all relevant building standards.Obtaining this approval typically involves creating a structural design for the foundation, including the process that must be performed during construction.

How Much Does The Underpinning Cost?

There are no standard costs for underpinning a house as each project is unique. Of course, if the problem is covered by your home insurance, the cost shouldn’t be something to worry about.

However, at Clifton Hill and Montpelier Builders & Construction, we can first evaluate the problem and then provide you with a free cost estimate. This estimate carries no obligation, and you can choose to work with us or not. However, we offer some of the most competitive prices in the industry, and we would really like for you to take advantage of our competitive pricing and top-notch workmanship.

FAQ’s

What is underpinning?
Underpinning is the process of reinforcing the foundation of a structure. Usually, underpinning includes expanding the foundation’s depth or spreading the load across a wider area. Underpinning is a major repair project, and to choose the right method, it is necessary to understand the current situation and the problems related to the entire foundation.
Can underpinning increase the cost of home insurance?
Historical underpinning may have less of an impact on your premiums, and if the floor has not moved for decades after its completion, chances are that the problems have been largely resolved.
How much is underpinning per metre?
In general, the premium costs for underpinning a foundation are between £1,000 to £1,200 per linear metre. However, you can request a free, no-obligation quote from us to know the cost of your project.
How long does the support take?
A typical basic job usually takes four to six weeks. Unexpected problems can sometimes arise during the underpinning process, especially in an older house. In this case, the project is usually a little longer.
Is subsidence a big problem?
Subsidence is one of the most serious problems that a property can suffer from. This can affect not only the structural integrity of your home but also the resale value. Don’t worry if you think you’ve noticed signs of subsidence in (or outside) your home. We can get it sorted out in no time.
Are cracks in walls signs the building has a structural problem?
Most small cracks in drywall or plaster walls do not pose major problems and result over time from the seasonal expansion and contraction of your home’s wooden frame. Larger cracks in your walls, however, can indicate structural or foundation problems.
Can a foundation be replaced?
Most damage to a foundation, including relatively serious cases, can be repaired. Theoretically, replacing a foundation is a fairly simple process. The house is either supported on the spot or raised and stabilised, the old foundation is torn down and removed, and a new foundation is built on the spot. The house then sits on the new foundation.
Can I take out building insurance for a property with underpinning?
Most cases of subsidence are insured, and the cost of stabilising your property is covered by your insurance. However, you cannot claim for underpinning if your property is experiencing subsistence when you are still covered by the new build guarantee that typically applies to all new or recently built properties.
Can you fix subsistence?
In more severe cases, underpinning may be required. This type of repair work usually prevents further movement of the foundation. Pipelines under or in your foundation can sometimes lead to subsidence if they leak or burst and wash away the earth.
What is the difference between settlement and subsidence?
The settlement only happens with new buildings. The settlement is similar to your building making itself comfortable or cosy on its new sofa.

Subsidence, however, is a completely different scenario. It is the downward movement of a building that sinks into the ground.

What are the first signs of Subsidence?
The telltale signs of subsidence include a diagonal crack, wider at the top than the bottom, visible inside and outside and located close to the doors and windows.

Other signs of subsistence are the wallpaper wrinkles on the wall, doors and windows that stick and frames that warp.

How is shoring different from underpinning?
Shoring is used to support beams and floors in a building while a column or wall is being removed. In this situation, vertical supports are used as a temporary replacement for the building columns or walls.

Shoring is intended to prevent collapse, while the shield is only intended to protect workers in the event of a collapse. Underpinning is the process of strengthening and stabilising the foundation of an existing building or other structure.

What is involved in the underpinning?
When foundations are being rebuilt, the depth of existing foundations is increased to transfer the building load to a more supportive type of soil.

Although there are a number of different techniques that can be used to support foundations, the most common method is traditional bulk concrete underpinning. This is a simple technique in which a floor segment is dug out under the existing building foundation in controlled steps to a depth at which suitable soil conditions exist. The excavation is then filled with concrete and allowed to harden before the next set is excavated.

Can I sell my house if it has subsidence problems?
A house with a subsistence problem will drop in value in the housing market. In some cases, a property can be sold at around 80% of its value. This is not a good thing; even assuming property agents want to market a property that has a problem.
Can you take out a mortgage if a property has suffered subsidence or is underpinned?
In general, there is no reason why a lender cannot offer a mortgage on an underpinned property as long as the survey report confirms that the work has been completed to a good standard and that there are no ongoing structural problems.
Do you undertake excavations?
Yes, Clifton Hill and Montpelier Builders & Construction offers you a complete package of basic structures, including drainage, basic beams, removal of overburden and blockwork up to the moisture-resistant top layer. We will also coordinate directly with your local building control/NHBC to obtain approvals when requested.
When can you start the job?
As a rule, we can start working on a new project 2 to 3 weeks after its receipt. We use the intervening time to requisition all the equipment and materials needed for the job. There are times when this may only take a week to over a month. Please contact us for more information.
Do I have to vacate my property while it is undergoing underpinning?
Clifton Hill and Montpelier Builders & Construction makes every effort to carry out repairs that allows you to stay where you are while you work.

In many cases though, the inside floor has to be raised. In such a case, the property will have to be vacated so we can work.

Do you visit the site before the project?
Yes. In this way, we can talk to you about your individual needs and evaluate all project requirements.

To talk more about your project, ask a question or get further clarification, please call 01273 257 224 or send an email to info@builders-brighton.com.

We would love to hear from you.

Are cracks in the foundation normal?
There should be no cracks, but you should look for the cause before proceeding with a repair.
