Thermal insulation and waterproofing of basements
When it comes to basement waterproofing insulation, many people only think in most cases about the use of traditional hot liquid poured, bitumen insulative sheeting. With traditional applications of insulation using a bituminous surface poured on in hot liquid form over 100m2, 120 and 180 FM bitumen welding bitumen is found. The size of this welding depends on the size of the parapet wall, the vents and positive / negative number of corners. The workflow using bitumen welding for the former three (parapet walls, vents and corners) cannot provide perfect security. Those professionals engaged in this kind of activity are in the know.
Inadequate insulation creates additional problems: exterior nitrate rot and a large amount of condensation. Due to its unmatched ability to adhere easily to the side walls and ceilings of basements, polyurethane is the perfect thermal insulation and waterproofing.
Perhaps the reason the use of insulation in basements has been left out of building insulation plans is that the appropriate technology was unavailable for use with their complex curves.
After the basement has been properly insulated, it is no longer able to soak up the cold from under the surface of the floor of the heated living space, as had previously traditionally been mitigated by placing a thick carpet on the floor.
