Frequently Asked Questions
What does waterproofing and detailing do for masonry?
It stops water getting into concrete, brick, blockwork and stone, and seals the weak points around joints, corners, outlets, flanges and penetrations. Pick your membrane or sealer first, then fit the matching detail products before the finish goes on.
Can these products go below ground?
Some do. The products here name retaining walls, cellar walls, basements, lift pits, planter boxes, tunnels and tanks. Check each product sheet for the exact use before you buy. Positive or negative water pressure, damp substrate and backfill timing all change what works.
What does a waterstop do?
A waterstop keeps a waterproof barrier continuous at construction joints, cold joints, cracks and penetrations. Mapei Mapeproof Swell swells when wet and seals around reinforced-concrete joints and penetrations. It backs up the membrane but does not replace joint design or concrete cover.
When would I use a penetrating sealer instead of a membrane?
Use a penetrating sealer when you want protection inside the substrate, not a surface film. These sealers treat concrete, brick, mortar, stone, tanks, walls, floors and warehouses. Check the absorption, moisture condition, and whether a later coating or finish must stick on top.
Why are corners and joint bands sold here?
Corners, joint bands, waterstops and patches keep the waterproofing continuous at the weak points. A prefabricated corner and a joint band or square bridge the changes in plane and thickness. Use only detail products that match the membrane you picked.
How do I choose the right membrane?
Match the membrane to the exposure and the substrate. A cementitious membrane suits a positive-side concrete or masonry face. A liquid-applied system handles movement and irregular surfaces. Read each product sheet for the job.
