Needle and Pile Underpinning

This method of underpinning can be used where the condition of the existing foundation is unsuitable
for traditional or jack pile underpinning techniques. The brickwork above the existing foundation must be in a sound condition since this method relies on the `arching effect' of the brick bonding to transmit the wall loads onto the needles and ultimately to the piles. The piles used with this method are usually small diameter bored piles.
