Project 4

One method of underpinning a house is illustrated in the photograph below. The weight of the house is first supported on jacks and piles are placed at suitable intervals and reinforcement attached to them. Concrete is then poured around it all and beams are formed to support the house after which the supporting jacks are either removed or sacrificed.

The right hand side of this photograph shows part of a house held up on jacks. In the centre a newly placed 13 metre deep pile projects out of the ground with space left around for reinforcement to be placed and concrete to be then poured. Crossing over the pile, there is to be a deep reinforced concrete beam, topped by a reinforced concrete slab. We designed this including the piles.
