Substructure Repair

Ansty Walk, Swindon

Project

Two unconnected semi-detached properties constructed from in-situ concrete panels, both split in to two flats

The rear stairwells to the first floor flats showed significant signs of on-going movement with cracks at varying heights.

Trial pits and dynamic probing confirmed the properties are founded on clay with high shrinkage potential and there was significant vegetation in the immediate vicinity. 

Underpinning had previously been recommended to the client.

Solution

The Bersche-Rolt engineer prepared a repair scheme using mini-piles as a less disruptive alternative to the previously recommended underpinning works in order to rectify the progressive movement of the foundations. 

The design also included the installation of masonry reinforcement and wall ties to repair and strengthen the superstructure, all of which was carried out by Bersche-Rolt site personnel.
