The horizontal barriers installed in the foundations ensure that moisture can not rise up to the masonry. This hydrophobic sealing or horizontal waterproofing works effectively preventing moisture from penetrating the masonry.
The houses of new construction must, by law, have a horizontal isolation, although unfortunately this can lose impermeability for different reasons and must be reinstalled or renewed later, as in many old houses, when they begin to have wet walls and wet walls.
Ignoring the problem can only cause damage to the structure of the building, a greater energy consumption and a decrease in the quality of life.
For the subsequent installation of a horizontal barrier there are different systems, procedures and techniques. In practice, when installed later, mechanical procedures are predominantly used, among which are the technique of inserting sheets, the technique of sawing the walls and different processes by injection.
The technique of inserting sheets consists of inserting sheets of stainless steel in a groove, while the technique of sawing the walls consists of sawing the masonry piece by piece and placing a closing fabric.
Finally, the cracks are combined with hydrophobic mortar.
The injection as a technique against rising damp
But the most modern systems, and also the most used at present for the subsequent installation of a horizontal barrier against moisture, are the different processes by injection.
These solutions can be applied without pressure, with low pressure, or with high pressure. The masonry is waterproofed with a pressureless injection reaching a relatively low degree of moisture transfer. This kind of waterproofing is also called hydrophobicization.
This is due to the fact that a liquid or a paste that repels water and that soon expands, hardens and thus forms a layer of protection impenetrable by water, which from that moment prevents it from entering holes previously drilled in the masonry, the humidity continues to rise.
