Strip foundation
Outwardly, strip foundations do not differ much from the piled ones. Such foundation are just more expedient when planning a house with a basement, or multi-dwelling homes. Besides, thermal insulation and water proofing must be placed over walls of the strip foundation. If groundwater is high, drainage is necessary. The making of strip foundations takes somewhat longer, as it is necessary to dig out the ground and to provide access to the strip foundation from all sides, to assemble moulds, and to install reinforced concrete.
