Description:

Liquid Asphaltic Composition is a two coat cold applied damp proof membrane which dries to a uniform gloss black finish.

The coating is a solution of natural and petroleum bitumens in white spirit.

Uses:

• LAC is typically used as a damp proof membrane to ground floors as a vapour barrier behind cladding and for tanking of basements.
• It is also suitable for waterproofing foundation walls ducts lintels columns beams and similar structures at above and below ground level.
• When designing Type A structures (as classified in BS 8102: 2009) the product applied correctly is capable of providing the levels of protection required for Grades 1 2 & 3 basements.
• LAC may also be applied to the internal face of external walls above ground level to prevent the penetration of moisture.
• The membrane can then be plastered or dry lined when dry.
• LAC may also be used to provide a barrier to Radon Gas.
