Waterproofing London

Frequently referred to as tanking, but more recently referred to as structural waterproofing, can often be one of the biggest and best decisions our clients have ever made.

Converting unused space, whether for a commercial or domestic benefit or creating a healthier environment to work or live in, also can add great value to your property financially.

Our comprehensive survey of your property means we can identify and advise upon which method of waterproofing should be used, which will give the most appropriate solution for your problem. Some circumstances can dictate both systems being used.

Here at City Remedial, we also offer a wide range of quality basement waterproofing services across London.

Cavity Drain Membrane Systems

In more recent decades, the system has been introduced to this country. And, when applied correctly, provides a flexible application that has a generally longer life span than cementitious systems.

The system incorporates the introduction of a drainage channel system to the perimeter walls, being directed into a sump/pump system. Additionally, the appropriate cavity drain membrane is fixed to walls/soffits utilising waterproof fixing plugs. A cavity drain membrane is laid loose to the floor slab and made watertight at all functions utilising waterproof sealing tapes, giving a dry internal surface.

Water penetration is then controlled and removed from the property via the sump/pump system, alleviating/controlling water vapour and damp pressure. Also, alarm systems are also available to the pumping system. Finished surfaces are dictated by the membrane being applied and the end-use. This can involve walls receiving a plastered finish, direct to the membrane, or a dry lining system, which can also incorporate insulation for thermal benefit.

Floors can receive tongue and groove timber flooring laid direct to the membrane or a sand and cement screed. Both finishes can incorporate insulation. Such finishes can be dictated by numerous factors which our surveyor will be pleased to advise and guide upon. Such works will be subject to our 10-year guarantee, insurance backed upon request. Periodic maintenance is required for this system.

Cementitious systems are provided in various forms, from cementitious slurries to multi-coat render applications.

The multi-coat render system is applied in layers to walls and floors that will form a dense cementitious material, incorporating a waterproofing component. This has been the traditional method of waterproofing in Britain for many years. Slurries are premixed coatings that are applied as a thin layer by either trowel, brush, or spray. Furthermore, both systems can be utilised internally as well as externally. All such applications require good surface preparation, which is vital to its success and may often require additional preparation for movement/construction joints. These applications are not subject to periodic maintenance programs.
Such works will be subject to our 10-year guarantee, insurance backed upon request.
