Concentrated silane/siloxane-based injection material against rising damp
A concentrated silane/siloxane-based injection material that provides a permanent solution to rising damp problems. Injected into the wall, it forms a chemical damp-proof barrier and prevents moisture rising from the ground from spreading through the structure.

On hollow brick walls the old, damp plaster is first stripped and HydroFix damp-proofing plaster is applied; the injection follows once the plaster has dried (24–48 hours). Holes 14 mm in diameter are drilled at the base of the wall at 10 cm intervals, angled 30° – 45° downwards. The concentrate is mixed with water at a ratio of 1:9 (1 part product to 9 parts water) and injected into the wall using pressureless or low-pressure injection equipment. The product spreads inside the wall and forms a chemical damp-proof barrier.
DampStop consumption is calculated not per square metre but by the length of the wall in metres and its thickness: ready-mixed solution, holes 10 cm apart — 1.5 L/m for a 10 cm wall, 2.25 L/m for a 15 cm wall. The Complete Kit (5 L concentrate = 50 L of solution) is enough for about 30–35 m of 10 cm wall or 20–25 m of 15 cm wall. For thicker walls, use the Consumption Calculator.
The continuous horizontal barrier forms within 48 hours after injection. Complete drying of the wall may take 4-12 weeks, depending on wall thickness and moisture level.
