Compost tunnels and mushroom cultivation cells are extremely sensitive to vapor transport. The risk of germs by vapor transport, infecting the tunnels and / or cultivation cells is a concern for every grower. Key aspects of vapor proofing and durability are the construction of the correct environment and ensuring the vapor resistance of the coating. For decades “CorrFill” has proven to be a perfect solution for when it comes to compost tunnel coating. Through the proper use of our CorrFill coating system we create an optimal, vapor proof finish of the walls, floors, ceiling and panel seams.
