Description.
A construction company were ready to start installing the lift within when they noticed that the lift pit was experiencing water ingress. The lift engineering company had stated that they would not install the lift until the lift pit was watertight.
A lift engineering company were carrying out their 6 months service and inspection programme to an existing lift installation and witnessed water ingress coming into the lift pit. The water ingress was also causing corrosion to the lift components which left untreated would rendered the lift unserviceable.
The client had requirement to waterproof localised areas of masonry to arrest running water that was causing damage to brickwork, overhead powerlines and track.
The client had a requirement to consolidate and fill voids to the ground at the back of the piled wall, which was identified due to the movement of the front façade of the building and the neighbouring 3 party structure. This was assumed to have been caused by the poorly constructed piles, and fines wash out during the excavation process.
The client had just purchased a property which was suffering from subsidence at the rear of the property. The subsidence cause at the rear elevation was due to the property being built on top of a layer of peat which was the primary cause of the subsidence.
A construction company were installing a water harvesting tank for a client that required waterproof tanking to retain water for the irrigation system for the large grounds within the property.
The concrete bund was deemed an environmental concern as containment could not be assured due to the level of deterioration of the concrete elements of the bund and sealant joints due to chemical exposure and general environmental degradation.
