6/12: Providing a damp-proof course below ground level

Providing a damp-proof course below ground level

Lay the first layer of bricks upside down. Maintain a broad joint, so that you can compensate for irregularities in the subsoil. Place a moisture-proof foil between the layer of bricks beneath ground level and the layer above it. In this way you prevent rising moisture. In order to obtain a thin joint here, we recommend adhesively bonding this foil with polymers. Place water-resistant insulation under the moisture-proof foil, for example XPS.
