Foundation formwork has material arranged over part of longitudinal vertices, which possess higher compressive strength than remaining material

摘要

The formwork has a material over a part of the longitudinal vertices, which possess a higher compressive strength than the remaining material. The material with higher compressive strength has higher density and is harder than the remaining material. The foundation formwork (1) is made of expanded polystyrene. Independent claims are also include for the following: (1) a system for manufacturing foundation from concrete (2) a method for manufacturing foundation.
