Tanking, cellar

London-damp-tanking: 96%

Converting a damp cellar or basement can be a surprisingly inexpensive way of increasing living space and can substantially increase the value of a property. Waterproofed cellars and basements can be converted into kitchens, bathrooms, wine cellars, living rooms, studies, or even recording studios. You are limited only by your imagination. In commercial premises, common uses for basements include, extra storage / retail space, car parks, bars/nightclubs, and restaurants.

Safeguard offers two main types of system for waterproofing existing cellars and basements. By offering both types of system we are able to offer an impartial opinion as to which system is best suited for a particular project.

Cementitious Waterproofing Slurries (Vandex system)

The Vandex Basement Waterproofing System – is a multi-coat waterproofing system that is both durable and versatile. The main coating material, Vandex BB75, is a cement-based powder which is mixed with water and applied to walls, floors, and ceilings by spray or trowel. It sets to form a bond with the masonry substrate, creating an impervious barrier to the movement of water.

Figure 1 shows a typical basement waterproofing application. A sand-cement render is applied to the walls and a bottle cove formed at the wall-floor junction using Vandex Unimortar 1. Two coats of Vandex BB75 are then applied to the walls and floor. Finally, a screed is applied to the floor and a suitable plaster is applied to the walls.

Studded Membranes (Oldroyd Membrane System)

The Oldroyd membrane system is particularly suited to waterproofing the Victorian basements commonly encountered in the UK as it does not rely on the soundness of the underlying substrate for its effectiveness. The membrane is sealed to walls and ceilings by means of special sealed fixing plugs, whilst on the floor there is normally no need for any form of fixing.

For a more eco-friendly solution, Oldroyd Xv Black can be used instead of Oldroyd Xv Clear. Oldroyd Xv Black contains between 56 and 70% recycled plastic.
