Underpinning is a way of strengthening and reinforcing the foundation of a building. It’s excellent for raising the thickness of the base if it’s been damaged. If you want to add more stories to your home, you can use this method. Tree roots could also damage the foundation and cause problems with your home’s structure.
The adjacent construction may have lower-than-existing foundations requiring lowering. If basements are built very close to an existing building, it may be necessary to change the foundation.
The reason is the existing house’s stability. Cracks may appear up to the base in a building and therefore need a remedy for the foundation.
METHODS OF UNDERPINNING LONDON
Mass Concrete Underpinning London Method
Also known as the Pit Process, underpinning Mass Also known as the Pit Process, underpinning Mass Concrete is the most common and the oldest of all methods or underpinning. This underpinning London process involves drilling holes along the building’s external wall at fixed times and depth below the current base. After a quick review of any potential problems, underpinning contractors London will fill the pits with concrete, leaving sufficient space for future dry packing.
When underpinning a house London, dry packaging aids are used for balancing the building’s weight and restoring a collapsing frame. In buildings where the original foundation was built on deep ground, mass concrete underpinning is used. It is a more cost-effective method because, in excavations, less hardware is used.
Base and Beam Underpinning London
This method of aid is more of an addition or an improvement to the Mass Concrete process. This form of underpinning involves the construction under the current base of a single concrete beam to provide power. Instead of pouring concrete into open pits as in Mass Cement, the underlying frame and beam use steel bars to support them.
The process involves digging holes along the outside wall and covering them with cement at fixed intervals, lowering metal frames into the pits. The effect is cement beams reinforcing existing structures and thus a better frame. This underpinning approach, often used for underpinning foundations where buildings require additional floors and require architectural use change. It is used in foundations both shallow and deep
Pile and Beam Underpinning London
For limited access systems that require deep foundations, this method is popular, with underpinning contractors London often favouring it for many reasons. The process begins by digging a hole under the earth and through the existing wall of the base.
Underpinning contractors London are using this method involves a hole that is designed to support a vertical concrete needle beam in the delivery of the load. Piles are then mounted with a steel frame for support on opposite sides of the gap or either side of the foundation wall.
With the needle beam going through the hole in the wall, the piles are then attached, firming up support. To fill gaps and add support to the beam, cement is applied. This process is used to move the existing load to a more secure and strengthened base from the initial framework. Others method of underpinning are:
Mini Piled Underpinning London
Underpinning contractors in London use this method, underpinning by cantilever needle beam method, and Pre-test method of underpinning.

Ceilings or floors that have separated from the walls, no matter how small the separation, this is a clear indication of foundation problems.
Underpinning London – Cracked floors
If your floors have cracks from wall to wall, this indicates foundation issues. If you have cracks only on a few tiles, this is probably caused by something else.
Underpinning London – Torn wallpaper
A cracked wall behind the wallpaper can cause it to tear and indicates structural damage.
Underpinning London – Wall rotation
Walls will rotate if the soil outside the foundations gets oversaturated with water, this causes the outside foundation wall to sink soil, the inside of the wall is higher and consequently the house walls rotate.
Underpinning London – Moldings detached from the ceiling and floors
Any detachment from floor or ceilings indicates structural issues and movement of the foundations.
Underpinning London – Stair step cracks in brickwork
This is a clear indication of foundation problems.
