With regard to solutions (or presumed such) forrising damp we introduce, after an under-floor cavity, the physical cutting of walls. Today we will deal with it analyzing all the details that have never been explained to you.

Physical cut of the walls: what it is

Physical cut of the walls provides, as its name suggests, a real cut parallel to plane at the base of the walls, then filled with waterproofing material (each company uses different materials).

History of physical cutting of walls

The basic concept of physical cutting is as simple as it is effective in blocking humidity rising, but extremely dangerous for the structure solidity where it is carried out. In past decades, it has been used to block rising damp but fortunately today less frequently, also due to catastrophic consequences on many buildings treated, following seismic events.

How to make physical cut of walls

Physical cut of the walls is an invasive work that should be performed in all the walls in contact with the ground to have a satisfying effect, and it involves the following phases:
  • horizontal mechanical cutting of the masonry throughout its thickness
  • washing to eliminate all residues inside the cut
  • injection (or insertion) of insulating material
  • restoration of masonry and finishing

Pros of physical cut of walls

  1. where present it blocks humidity rising physically

Cons of physical cut of walls

  1. it cannot be applied to load-bearing walls and pillars, leaving some points uncovered where humidity may rise
  2. it weakens building structure
  3. it cannot be applied to floors

Cost of physical cut of walls

It costs € 200/700 per linear meter.
