WATERPROOFING MEMBRANE
Membrane waterproofing can be liquid or sheets type lay over a concrete surface to protect the structural slab from water seepage. Laying preferably be done to fall to ensure water flows into sumps or drains and prevention of water puddles on the surface to avoid any seepage into the slab. Sheets type waterproofing membrane can be wet applied self adhesive, geotextile laying or torch-on.
