    Encapsulation of a crawl space in Bois-Des-Filions, Qc

    The problem:

    This Bois-des-Filion customer contacted us so that we could solve his mold problem in his crawl space. This is caused by the high humidity in it. In addition, there was a lot of wood which was rotten and it was necessary to act quickly so that the problem does not get worst.


    The solution :

    One of our certified specialists visited his crawl space and suggested that we need to first remove the mold that was present with our Mold X product. Subsequently, our foreman installed a drainage membrane to facilitate the flow of water.

    Following this, we encapsulated this crawl space with our CleanSpace membrane, this membrane mainly serves to prevent water vapor from coming out of the ground and going up to the upper floors. When everything was finished and to maximize the efficiency of the CleanSpace system, our specialist installed our product Sedona SandiDry, which is a high performance dehumidifier. Its goal is to dry out your crawl space as much as possible and reduce the humidity level as much as possible.

    Since our intervention, this client from Bois-des-Filion now benefits from a dry crawl space without mold.
