Fosroc Proofex LM 28kg

Proofex LM is a bituminous rubber emulsion combined with special hydraulically hardening fillers, supplied as a powder and a liquid in a single pack. The powder is mixed into the liquid with a slow-speed paddle and the material is applied by steel float in one or two even layers. Because it is trowel-applied, it forms a continuous barrier around pipe entries, covings, pile caps and other complex details where sheet membranes cannot easily be dressed in.

The cured membrane is seamless, flexible and resistant to aggressive groundwater, and it withstands a substantial hydrostatic head. Being solvent-free, it is harmless to groundwater and suited to enclosed working. For areas of higher loading, such as covings, edges and penetrations, Proofex LM can be reinforced with Proofex LM Mesh to add strength at these vulnerable points.

Benefits

• Seals intricate details such as pipe entries and covings that sheet membranes cannot easily cover
• Cures to a seamless, joint-free film, removing the laps that are common failure points
• Tolerates damp substrates, reducing downtime waiting for surfaces to dry
• Resists aggressive groundwater and high hydrostatic pressure for dependable below-ground protection
• Solvent-free formulation is safer in enclosed spaces and harmless to groundwater

Good to know 

• Substrates must be primed first; the primer is made by diluting one part mixed Proofex LM with ten parts clean water
• Supplied in 28kg two-component packs (powder plus liquid)
• Reinforce high-load details with Proofex LM Mesh
