To insulate a foundation from the outside is very good but it must be done with the right product and the right way. In this case the contractor has put a ball styrofoam and non-moisture resistant. As a result, the foundation deteriorated prematurely and the insulation filled with roots. It is important to apply a good layer of waterproofing membrane to the foundation in the first place and then apply EXTRUDED STYROFOAM resistant to mold. In this way, there is no chance that the roots will lodge there and that the humidity will not remain trapped.
