SovDrain Type C Wall & Floor Membranes

Sovereign offer a unique service within the waterproofing/basement conversion industry in that we are able to assist with your project from initial design through to full individual specification and the appointment of an approved contractor. 

The Sovereign SovDrain Cavity Drainage Membrane Systems are used to waterproof walls and floors above and below ground level, internally and externally and also vaulted construction and tunnels.

The system which contains a wide range of finishes can be employed to walls and floors works by lining the area to be protected with the SovDrain Cavity Drain  Membrane (CDM3, CDM8, CDM20, Laths available). On the internal surfaces, all membrane joints and fixings are sealed using the SovDrain range of sealing products to prevent any ingress of moisture or water. The systems can also be used as protection against contaminants such as salts, carbon deposits, fertilizers & radon, for example.

SovDrain Cavity Drainage Membrane System conforms to BS8102 “Code of Practice for Protection of Below Ground Structures against water from the ground” and can be termed as Type C Drained Protection.

In above ground situations any dampness/moisture that enters through the structure is collected behind the system and is dealt with by ventilation and/or dissipation into the solum.

Where there is likely to be build-up of water behind the system, such as in below ground situations, an effective drainage facility must be created to drain such water away, and prevent any standing/collecting water and hydrostatic pressure build up.

A wide range of finishes can be employed to walls and floors. These provide protection to the membrane, and create a decorative finish.

Sovereign also provides a range of Sumps and Pumping Systems, including accessories such as Power Backup and Alarms for use with the SovDrain CDM System, where a safe form of natural drainage is not available.
