GCP Applied Technologies provided waterproofing solutions for the Gatwick Airport North Terminal extension.

Principal contractors Morgan Sindall PLC, required a waterproofing solution that could be applied quickly, trafficked immediately and that would simplify detailing at terminations and penetrations.

The membrane also needed to be damage resistant.

The upper forecourt, at the passenger entrance to the terminal, was upgraded with a strengthening screed insulated, and then re-waterproofed with Silcor®spray applied liquid waterproofing.

Silcor® is a rapid set polyurea, two component liquid waterproofing system with exceptional physical properties. The system has a BBA Certificate and a European Technical Approval (ETA).
