Fast to apply, crack-bridging, polyurethane and polyurea based liquid membranes. Sika liquid applied membranes (LAM) are highly elastic and flexible polymeric systems, usually based on polyurethane or polyurea resins with excellent technical properties for high performance applications. These materials are applied on prepared / primed external concrete surfaces by spraying and provide excellent solutions for complex detailing.

Liquid applied membranes will also prevent any lateral water underflow in the event of local damage. Application below the base slab is done on a special fleece before the structural concrete slab is placed.

Sikalastic® polyurea systems are ideally suited to the waterproofing of podium deck slabs and compatible with Sika solutions for below ground waterproofing, thereby offering a one-stop-shop solution for waterproofing the entire structure.
