Secondary horizontal wall insulation in accordance with WTA guidelines
Over the years, a number of technologies have been developed to enable the implementation of so-called secondary horizontal insulation in walls. Their aim is to effectively stop capillary moisture rising, which leads to the degradation of masonry structures.
The current state of knowledge on the mechanical reconstruction of horizontal insulation and its practical application is described in detail in WTA guidelines no. 4-7. This document, developed by WTA International – the Scientific and Technical Association for the Conservation of Buildings and the Protection of Monuments, was updated in April 2024.
Mechanical methods of secondary horizontal waterproofing
Although mechanical methods are used less often than chemical techniques, they have been practiced for decades and are considered to be one of the most reliable ways of stopping capillary moisture transport – provided that the work is properly planned and carried out. A durable, completely water-impermeable layer is created in the cross-section of the wall, which effectively blocks moisture rising – similarly to newly constructed buildings.
Mechanical insulation requires the physical separation of the wall by creating at least one continuous gap that interrupts the capillary moisture transport system. It can be implemented in two ways: one- or two-stage. In the first variant, a space is first created in the wall, and then the insulating material is placed in it. In the second variant, the separation of the wall and the introduction of insulation take place simultaneously.
Each design of mechanical horizontal insulation should take into account the individual structural features of the building, the principles of building physics, technical and utility requirements, as well as economic, environmental and conservation aspects. The correct design of connections between different types of moisture insulation is of particular importance.
Mechanical methods of performing secondary horizontal insulation include, among others: replacing the wall, pressing in stainless steel sheets, undercutting the wall and using drill cores.

Warranty
We provide 30-year warranty for our services.

Effectiveness
Our method guarantees 100% cut-off of capillary moisture – the problem does not return until the end of technical life of the building.

Versatility
The method can be used in most of the buildings, regardless of wall moisture level and thickness.
