Tanking sheet fitted to form dpc barrier prior to plasterboard being fitted.

Tanking is a term used for creating a tank like seal to protect walls against water penetration. The Building Regulations stipulate that tanking must be applied to all new build structures below ground, but tanking can also be applied to existing buildings, to prevent water penetration and into basements and cellars, as well as helping to tackle rising damp.

The two main methods of tanking are by using a membrane or a coating. The type of damp and the precise requirements of the building will determine the most appropriate method to use, and sometimes a combination is required to ensure walls remain dry.

Lateral restraints.

Lateral restraints are designed to restrain the whole of the brick outer structure to the floor joists to provide structural stability. Lateral restraints are manufactured Stainless Steel rods and are 8mm in diameter. They are supplied in standard lengths of 1 and 1.5 metres.

Stitch bars installed prior to plastering.

Crack stitching is a masonry repair technique that reconnects and reinforces cracked walls. It includes stainless steel helical bars that stitch across the fractures to strengthen and repair cracks.

Finishing.

Following remedial works, plasterboard is installed.
