MECHANICAL / PHYSICAL DAMP PROOFING SOLUTIONS
This is the oldest method. The mechanical or physical damp proofing solutions attempt to insert a new damp proof course into the masonry. The wall is drilled or cut-through horizontally and a new solid damp proof course is inserted into the gap.
Several such technologies have been developed, the most important ones are the following:
- Wall substitution: Several layers of bricks in the base area are replaced by new material, and a new damp proof course is also inserted.
- Metal plates insertion: The wall is cut through horizontally in its length with a diamond chainsaw and special chromium-nickel-molybdenum steel plates are shot into the brickwork.

- Drill core procedure: 8-10 cm diameter holes are drilled alternatively into the wall base, then the holes are filled with waterproof concrete.
