Why do Buildings Need Underpinning London? Read about Alexson’s Underpinning Foundations & Underpinning Basement
Underpinning London foundations is performed to strengthen the foundation and strengthen the building. This is often needed as a consequence of subsidence, which can happen when extra floors and extensions are carried out on the property. It can also be needed as a result of inadequate initial construction by the original underpinning company London.
If you are notified that underpinning of your home is needed, it’s usually because a form of subsidence is causing your home to sink into the ground. This typically occurs because the soil from beneath your property has shrunk or moved. Or, it can happen because originally when the original foundations were laid, the ground was incorrectly assessed before the groundworks were made.
Typically, subsidence occurs more in semi and detached houses, but any building can be affected. Even mid-terraces, if they have been built over old river beds. This is something that can be checked by a structural survey, before purchase. Some underpinning foundations have been performed because a survey carried out when they purchased their property, hadn’t seen that the neighbour to the semi-detached property has also been underpinned.
If you are considering buying a house in the southeast of England, clay soil is abundant, knock on the doors of nearby houses where you are thinking of locating to, and ask if their properties have been underpinned and If there has been a problem with subsidence.
At Alexson, we are renowned for our extensive industrial experience and construction knowledge and for being a reliable, skilled underpinning company London based. We know that potential subsidence can be indicated by cracks in the brickwork or render and also blown tiling on the inside 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 information about underpinning 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)
One of the most common underpinning methods used by underpinning companies London based is the pit method, also known as the mass concrete underpinning method. This is a cost-effective method, suitable for shallow foundations, it is a traditional method that has been used for centuries. The existing foundation is extended until it meets a stable stratum. Following this the soil beneath the foundation is then excavated in stages and finally, the excavation is filled with concrete.
Underpinning By Cantilever Needle Beam Method
This underpinning method is an extension of the pit method. It can only be used if the foundation has to be extended on one side only and the plan possesses a stronger interior column. This method is faster compared to the pit method and has a higher load-carrying capability.
Mini Piled Underpinning
This underpinning method is used when the loads from the foundation have to be transferred to a distance greater than 5m from the excavation site. It can also be adapted for soil with a variable nature. Steel case piles are driven into the ground with diameters of 150-300mm. A disadvantage to this method is that access is restrictive and it causes environmental pollution problems.
Pile Method of Underpinning
Settlement in soil due to water clogging or a clay soil nature can be treated using this method. Piles are driven into adjacent sides of the wall that is supporting the foundation. A needle, or pin, is then penetrated through the wall and acts like pile caps.
Pier and Beam Underpinning Method
This method is also known as the base and beam method, it began to be used following the second world war. The traditional mass concrete method couldn’t work for a large depth foundation, so a different method had to be implemented. This method is used and found economical on foundations up to 6m depth. It can be utilised in most ground conditions. Reinforced concrete beams transfer the load to mass concrete bases, also known as piers. The size and depth of the beams depend upon the ground conditions and the loads involved.
