Sealing and repair
Horizontal damp-proof course
When moisture rises from the ground through masonry, no surface sealing helps: the water comes from below and finds its way. A horizontal damp-proof course lays a water-repellent plane across the wall and cuts the rise off. Which method fits is decided by the state of the wall, not by a catalogue.

services offered by the practice
Cutting off capillary rise in masonry – with injection cream in drilled holes or mechanically.
Typical occasions
Wann diese Untersuchung sinnvoll ist
- A damp line climbing the wall from the floor
- Salt efflorescence and flaking plaster at the base
- An older building with no effective barrier layer in the masonry
- Before internal insulation: stop the moisture first, then insulate
Methods used
Womit wir am Bauwerk arbeiten
- Measure first: determine saturation and salt load, or even the best barrier will not work
- Injection cream in drilled holes: a row of holes in one bed joint, cream introduced without pressure
- The cream spreads through the capillaries until the plane is closed
- Mechanical method where the masonry allows it: a barrier sheet driven into the continuous bed joint
- Allow for renovation plaster and drying time – a wall does not give up its water overnight
What you receive
Das erhalten Sie
- Capillary rise interrupted, proven by follow-up measurement
- A drilling record with position, spacing and quantity
- A realistic figure for how long the wall needs to dry
- A recommendation for the wall build-up afterwards
