Damp proof membrane that offers easy, flexible installation
Monday, September 15, 2014
Building Regulations Approved Document C (Site preparation and resistance to contaminants and moisture) states; ‘floors next the ground should resist the passage of moisture to the upper surface of the floor’.
Damp proof course in walls should link with damp proof membrane in floors.
EPDM damp proof membrane as supplied by Russetts Developments Ltd is used for sealing buildings to keep them damp and wind-proof. This system is installed in cavity walls and around the window frames of residential and commercial buildings. EPDM damp proof membrane can be attached to any type of substrate to prevent moisture penetration.
Damp proofing a home or business is essential to prevent the risk of perpetual damp. Moisture, water and wind can enter a building through the foundations, masonry and window or door seals. The exclusion of moisture and retention of heat also means a building is more energy efficient thereby applying with the UK Government carbon-emission targets. Damp proof membrane is installed under the floor of a building and above a layer that will protect it such as a layer of sand or insulation material.
Rising damp, generally from a natural phenomenon known as capillary action whereby moisture is pulled up from the ground through porous surfaces such as bricks, is best dealt with by installing a damp proof membrane. Not only does it prevent damp, but also reduces heat leakage from a building.
There are a number of ways of preventing the ingress of moisture into buildings, but a system that is proving to be highly successful is EPDM damp proof course.
Characteristics of EPDM damp proof course membrane lend itself perfectly to the job:
• Exceptional contraction and expansion characteristics with up to 400% elongation
• Temperature stable from -40°C to +120°C
• Superior resistance to weathering, ozone and ultra violet
• Excellent chemical resistance
• Will not discolour masonry
• Life expectancy of over 40 years
• Compatible with a wide range of substrates
• Contains no environmental pollutants
