Technical properties
- “CAPILASIL HS” is a water-repellent and hydrophobic injection agent.
- The product is specifically designed to block capillary rising moisture in wall foundations and lower sections.
- Contains special additives that ensure high efficiency even in structures affected by aggressive salts and nitrates.
- Fills the material's pores and forms an impermeable hydrophobic barrier, while allowing the wall itself to maintain vapor permeability (breathe).
APPLICATION AREAS
- Injection treatment of foundations and walls to stop rising moisture from the ground.
- Designed for the masonry of old and new buildings: red bricks, natural stone, and mixed walls.
- Ideal for objects diagnosed with high levels of ground salts and nitrates.
ADVANTAGES
- High efficiency: blocks moisture where ordinary hydrophobizers fail due to salt effects.
- Preservation of material breathability: does not form a film, does not reduce vapor permeability.
- Deep penetration: due to low molecular weight, it migrates deeply into capillaries and micro-cracks.
- Protection against salts: neutralizes the negative effects of nitrates on foundations.
- Safety: water-based composition, free of harmful organic solvents or strong odors.

| USAGE DATA | |
|---|---|
| Consumption (Consommation) | • Depends on: wall thickness, material porosity, and the amount of voids. • On average, 1.5 to 3 liters are consumed per meter of wall length (calculating for a 10 cm wall thickness). |
| Application temperature | Min. +5 °C, max. +30 °C. |
| Full reaction time | The chemical barrier fully forms within 14–28 days. |
DRILLING AND PREPARATION OF HOLES
- Drilling line: holes are drilled in a horizontal line, as close to the foundation or ground level as possible (usually in the first or second mortar joint).
- Distances: holes are drilled 10–12 cm apart from each other.
- Angle: drilled at a 15–30 degree angle downward, so that the poured liquid flows more easily into the wall.
- Depth: the hole depth should reach approximately 90% of the total wall thickness (e.g., if the wall is 40 cm thick, drill 36 cm).
- Cleaning: the drilled holes must be blown out with compressed air or cleaned with a vacuum to remove dust that could clog the capillaries.
INJECTION PROCESS (MISE EN OEUVRE)
- Gravitational method (without pressure): special funnels / dispensers are inserted into the holes, which are continuously filled with "CAPILASIL HS" until the wall is fully saturated and the liquid stops being absorbed.
- Pressure method: special injection packs and low-pressure pumps are used. This method is recommended for very thick or very damp walls.
- Sealing: after completing the injection work, the holes are sealed with waterproof cement or lime mortar.
PRECAUTIONS AND TIPS
- If the wall has large internal voids or cracks, they must be filled with liquid mortar before injection to prevent the material from leaking out.
- Use only clean tools. Do not leave containers open so that the product does not start reacting with environmental moisture prematurely.
- Before starting work, it is recommended to measure the wall's moisture and salt concentration.
SAFETY
- The product may irritate skin and eyes. It is essential to wear protective goggles, gloves, and appropriate work clothing during work.
- If it comes into contact with skin, wash immediately with plenty of water and soap. If it gets into the eyes – rinse with plenty of running water and seek medical attention.
ENVIRONMENTAL PROTECTION
Ensure that product residues do not enter groundwater, drainage systems, or sewage. Dispose of empty containers at specialized waste collection points.
