What is the foundation gap
The base joint is a horizontal plane where the earth is bonded to the ground. It must be located at a non-frosty depth, so its minimum depth for laying 80 cm below the treated terrain. The joint depth also depends on the location of the future construction. A load from the top structure is transferred to the foundation joint. All loads are transferred to the base ground. Concrete, insulation and concrete foundation are laid on the foundation joint. The protection of the foundation joint before crushing requires that the machine depth is at least 0.2 m in a cohesive soil at the base joint, which is then uncovered manually before casting. It is not appropriate to uncover the foundation joint from the cold before the soil does not freeze and then melt during melting.
