This building material is suited for the construction of thermally insulating structures potentially one day replacing concrete.
It’s a composite made from two layers, one that is structural and one that provides insulative properties. The structural layer is traditional cob using high-strength fibers, like straw along with a high clay content binder. This is combined with the insulating layer which is much less dense to form one product.
The inherent clay properties allow the two layers to join when mixed with water. This means that no other additional binding or adhesive materials are needed.
The resulting wall is made from subsoil and locally produced fiber which helps minimize additional transportation and create a low-cost system. This innovative process and product are a distinct improvement for installation compared to standard solutions for on-site built wall systems.
The goal of Project CobBauge is to create an economical, insulating construction material with low environmental impact and to reduce the volume of waste landfilled by using the earth already in place for the construction of buildings.
