With the repurposing of many buildings across the capital, we’re often called upon to perform mass concrete underpinning or underpinning basements to support increased usage and load.

Why do Buildings Need Underpinning London? Read about Alexson's Underpinning Foundations & Underpinning Basement

When it comes to underpinning foundations in London properties, it is done to strengthen building foundations, which is required as a result of subsidence, often a result of the addition of extra floors (including extensions above adjoined garages); or inadequate initial construction by the original underpinning company in London.

When you are informed that underpinning at your London home is needed, it is often because the building is sinking into the ground: a form of subsidence. As an experienced underpinning company in London, we know that this can happen because the soil beneath your home has shrunk or moved (as is reasonably common with clay-based soils), or because the ground's characteristics were improperly assessed when the original foundations were laid.

In many cases where underpinning foundations work at London properties is needed, subsidence is more likely to affect semi and detached properties, but in reality, any home can be affected. Even mid-terraces built over variable ground, such as old river beds, an issue that can be picked up by a structural survey before purchase.

For some underpinning foundations work at London premises, survey’s won't pick up if a neighbouring property, such as the other half of a semi-detached, has been underpinned. If you're looking at buying a home in an area with clay soil (particularly prevalent in the Southeast of England), don't be afraid to knock on nearby doors and ask if their property has been underpinned in the past.

At Alexson, we are known for being a trusted and experienced underpinning company in London. Thanks to our vast industry knowledge and experience, our underpinning team know that signs of potential subsidence can include cracks in the brickwork or render, and blown tiling on interior walls.

When it comes to doing underpinning work on your London property, keep in mind that there are several things that can cause blown tiles, including leaking pipes, so their presence should ring alarm bells – they mean something, somewhere is wrong. For more about underpinning in London, contact Alexson.

For all these issues, we are an underpinning company working with London clients to provide structural integrity and solid foundations, and we know the importance of this work.

Underpinning London Methods by best Underpinning Company

Mass Concrete Underpinning Method (Pit Method)

For certain underpinning projects in London, the mass concrete method is the traditional one. This kind of underpinning for foundations in London buildings involves extending the old foundation until it reaches a stable stratum. Soil below the existing foundation is excavated in a controlled manner through stages or pins for this underpinning at London sites, a low-cost method for the shallow foundation.

Underpinning By Cantilever Needle Beam Method

As an experienced underpinning company in London, we often use the cantilever pit method. If the foundation has to be extended to one side and the plan possesses a stronger interior column, this method can be used for underpinning foundations at your London site.

Mini Piled Underpinning

When it comes to underpinning foundations in London, this method can be implemented where the loads from the foundation have to be transferred to strata located at a distance greater than 5m. Our underpinning company teams in London know that this method is adaptable for soil that has variable nature, access is restrictive and causes environmental pollution problems.

Pile Method of Underpinning

Using this method for underpinning foundations in London buildings piles are driven on adjacent sides of the wall that supports the weak foundation, and a needle/pin penetrates through the wall that is in turn connected to the piles. Settlement in soil due to water clogging or clayey nature can be treated by this method of underpinning in London.

Pier and Beam Underpinning Method

For underpinning foundations in London properties, this method is known as base and beam method. This form of underpinning in London grew popular due to the mass concrete method being unsuitable for work of a huge depth, and it is feasible for most of the ground conditions. The size and depth of the beams are based on the ground conditions and applied loads.
