Clay panels are made from cardboard where the cores of the board are filled with a bentonite clay that expands when water contact is made. Eventually, the cardboard panel deteriorates away leaving a monolithic layer of clay to stop water leaks in buildings.

These are all recommended to be applied over a monolithic, solid deck of some type, but typically concrete. Insulation, protection boards, drainage board, then concrete or soil, garden vegetative materials, or sometimes pavers are used for coverings. For vertical walls, the material is adhered to the wall, then a protection board and possibly a drainage board is installed to protect the membrane during backfilling.

The thickness is about the same as a thick cardboard panel. The material is fastened to walls using powder actuated tools with the clay self sealing around the nail holes.

The system must be installed to the manufacturers installation instructions, the listing, where applicable, and the building code.
