How do you waterproof a concrete slab?

With the pre-applied waterproofing, the waterproofing barrier is laid before pouring the concrete slab and walls. The concrete is then poured onto the membrane, forming a bond to keep water and moisture out. When you understand that water enters through the tile, you should apply the waterproofing. If you find the right place, you can apply some plaster.

But it's not a permanent solution. So the best solution is to apply waterproofing to the slab. Water can mostly seep through the edges and corners. So you tightly cover the edges and corners.

When you prepare the edges, make it like a steak. So it's the best way to bring together better. After applying the primer now, you can directly apply the waterproofing. If you have chosen liquid membranes, apply them in two layers perpendicularly.

You can use a roller, brush, or any sprayer according to the thickness of the layer you need to maintain. Some companies sell sealants and coatings for the residential market, usually epoxy or urethanes to seal the tile. For these products to adhere properly, the floor must be clean, dry and free of impurities. Shot blasting is often used to prepare the surface.
