SealCrete RapidPatch
Fast-setting hydraulic cement for concrete cracks
The one you reach for when water is already coming through — it sets in three to five minutes and will patch a 20 mm hole under active pressure.
Use it for
- Patching active leaks in concrete, up to 20 mm holes
- Sealing floor and wall joints
- Sealing settlement cracks in masonry walls
- Stopping seepage before applying a waterproofing system
Why this one
- Sets in 3 to 5 minutes
Fast enough to hold against running water, not just seepage - Works under water pressure
Patching under active pressure will not affect its hardness or strength - 300 psi in the first hour
Full strength at seven days - Two mix ratios
Stiffer for active leaks, slightly wetter for seepage - Hand, trowel, or putty knife
Force it into the opening and hold for two to three minutes - Stops leaks instantly
From seepage right through to running water
