ABSTRACT:
The gully closure for preventing the pollution of bodies of water in accident situations consists of a flexible mat (1) which covers the gulley surface and is coated with a highly viscous, free-flowing moulding composition (2). A plastically deformable silicone gel has proved particularly successful as a free-flowing moulding composition (2).
