Waterproofing Suspended concrete slab
Waterproofing Suspended concrete slab Method
1. Prepare suspended concrete slab surfaces to be treated by removing any loose materials ensuring a clean and sound surface.
2. Any damage to the slab surface should be repaired using MAXREST.
3. Any missing mortar can be replaced with MAXREST
5. Hairline fractures up to 3.5mm wide can be coated with MAXSEAL FLEX without filling.
7. Leave to cure for a period of 3 days minimum before the laying of the tile bed.
Sealing a suspended Concrete Slab with Drizoro Maxseal Super
First part of Waterproofing Suspended concrete slab this way is to spread the Drizoro Maxseal Super below the slab itself before the pour.
Second part of the application is performed on the fresh concrete, after leveling. The concrete slab has enough strength to be walked over. But still fresh enough to dampen the surface when troweled.
The product is spread in powder form as supplied at a ratio of 1,5 to 2,5 kg/m2, endeavouring to achieve a complete and uniform coverage. Immediately after the surface is sprayed to prevent the superficial drying of the slab and to make the power troweling smoother.
The troweling will provide a monolithic waterproof layer, which can be slightly dampened during this operation to improve the penetration. This prevents an excessively quick drying, which would prevent proper hydration of Drizoro Maxseal® SUPER.
Singular spots such as columns, penetrating pipes, corners, concrete joints, and expansion joints should be treated and sealed prior to general application. See below
