Horizontal insulation is a moisture protection for walls. It is placed between a wall and a solid strip or between the walls on the ground floor and the foundation. Due to the applied waterproofing, moisture does not penetrate vertically into the walls, thereby protecting them from damage. It also plays a second important role, separating the walls from the ground. This is a clear boundary between the foundation and the ground. High-quality horizontal insulation reduces cracking of walls, subsidence of the house or rapid wear of the foundation. This is an element of the house that requires increased attention, as it plays a key role in its subsequent use.

What materials can be used to make horizontal insulation?
Previously, the most common material was roofing material. A lot has changed in a few years. New, higher-quality products have been developed to ensure good waterproofing of buildings. The most common use cases:
bitumen mass – this preparation, after drying, creates an elastic waterproof coating, which is an effective protection against water.
heat-welded roofing materials are equipped with a polyester fiber matrix and then covered with bitumen mass. Most often sold in rolls. They are extremely resistant to mechanical damage and are very flexible, which prevents their destruction. The thicker the felt, the less risk of damage. For their assembly, insulation and special mastic are needed.
thermal insulation membranes are a thin material with a thickness of 0.2-2 mm. For appropriate horizontal insulation, it is recommended to use 0.4 mm thick membranes. Depending on the model, they may have protrusions or easily connect to the solution on which they are installed.
Negative consequences of the lack of horizontal insulation
First of all, the lack of waterproofing means increased humidity in the house, which means mold and mildew on the walls. Concrete in its structure has pores that act like a sponge, they quickly absorb water. This leads not only to mold formation, but also to peeling of the cladding, biological corrosion of concrete and even loss of stability of the building. This is due to the fact that in our climatic zone, the water inside the walls can freeze and thaw up to 200 times, which puts a heavy burden on the construction of the object itself.
