Membrane Systems are a complete range of systems used together to solve Damp problems in construction projects.

Membrane Systems are exceptionally effective in dealing with aggressive ground water conditions, basement or barn conversions, and even as a barrier against Radon Gas.

There are numerous different types of Membrane Systems that can be used depending on the application.

A Cavity Drain Plastic Membrane System is fixed to the walls and floor to create drainage paths for moisture. Constructed from High Density Polyethylene (HDPE) and Polypropylene (PP), these membranes are water and vapour resistant. Any water present is collected in a channel at the base of the construction and then drained out of the building. These membranes can be used in both sealed and ventilated installations, and forms a permanent seal between the building structure and internal fixtures.

Sealed Cavity Drain System is recommended where active or running ground water is evident. Depending on the desired drainage flow rate, the membrane may be installed to the underside of a vaulted ceiling or to the underside of a slab for a complete seal. All fixings, penetrations or joints are further sealed, and a pumped drainage system may be fitted to prevent any formation of damp.

Ventilated Cavity Drain System can be used where no active water is expected. These types of systems can be ventilated at the membrane or through the use of an external vent. This system is more suited to restoration projects; it will keep the fabric of the structure unchanged and also keep any internal surface dry and free from damp. This system can then be dry-lined or plaster finished depending on the project requirements.
