This final solution against rising damp forms a water-repellent, horizontal barrier in walls
For all types of brick and rapid construction brick, even hollow ones
Can be used as a joint sealant in solid natural stone walls
Applicable inside and outside
WTCB AAA+
Instructions
Remove skirting boards, cover plates of sockets and all plastering up to 25 cm above the visible moisture attack or salt efflorescence
Drill a 12 mm diameter hole every 10 cm. The depth is the wall thickness minus 5 cm
For fastest effectiveness, drill into the lowest horizontal cement joint, above the ground surface outside
Inject double walls and walls thicker than 40 cm inside and outside at the same height
For very porous stone such as sandstone, ironstone or some types of limestone: it is best to also inject the stone itself. Follow the lowest joint in natural stone. If there is an old water barrier, drill below that level
Drill several star-shaped holes in corners for complete impregnation
Remove all drilling dust from the holes
Screw the injection hose onto the sausage. Insert the hose into the drill holes to the back and fill with a slow retreating motion
Leave the last cm unfilled
Seal the holes with Tec7 Filler
After a few days to weeks (depending on how dry the wall is) a +/- 10 cm thick water-repellent layer will have been formed across the entire width of the wall. The wall will take longer to dry, depending on the thickness of the wall, the weather conditions and the moisture content
If necessary, measure the evolution with a moisture meter
If the walls do not dry, or stains appear at normal humidity, there is heavy salt stress. This can be remedied by a wall treatment with WP7-501 Wall + Basement Waterproofing
Penetrating driving rain that prevents drying can be remedied by facade treatment with WP7- 401 Facade Waterproof
Wait to finish until the walls are thoroughly dry. Good ventilation promotes the drying process. Wait at least two weeks before installing a construction dryer if necessary
Do not install a retaining wall to prevent moisture problems in the form of corrosion, deterioration of the walls and severe mould or occurrence of house fungus
