FIBELASTIC PLT is a high performance, single component PMMA & acetate hybrid waterproofing system. It is spray applied in a sandwich structure between two layers of sprayed concrete/cast concrete layers creating a double bonded composite shell lining. 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.
