Liquid-applied membrane (LAM) is a monolithic, fully-bonded, liquid-based coating suitable for many waterproofing and roofing applications. The coating cures to form a rubber-like elastomeric waterproof membrane and may be applied over many substrates, including asphalt, bitumen and concrete.

Liquid-Applied Membrane Is a Popular Choice Because It Is...

  • Ideal for exposed roofs with large number of complicated details and penetrations
  • Cost-effective, especially for roof renovations and roof repair projects
  • Seamless, fills in cracks, gaps and voids in substrate
  • Easy and safe application
  • Durable
  • Rapid curing and excellent adhesion to all kinds of surfaces
  • Applicable for a multitude of waterproofing needs, not only roofs
