Waterproofing mortars, Sikalastic®-345

Sikalastic®-345 is an EVA polymer based, sprayable membrane for the waterproofing of underground concrete structures. It is spray applied in a sandwich structure between two sprayed concrete / cast concrete layers, creating a double bonded composite shell lining. It is flexible and has very high bond strength properties on both sides of the membrane. It is an effective alternative to conventional waterproofing sheet membranes.

As a double bonded system, this provides excellent water tightness, preventing the development of water migration on both sides of the membrane.

As with all spray applied membranes, it is not possible to seal against water ingress through the substrate. In such cases a drainage system or local water management using drainage pipes should be used in combination with Sikalastic®-345. However, it can be applied to

damp substrate (as long as there is no running water).
