Tips Before Starting Waterproofing Works

Flawless surface preparation: Before applying waterproofing, the concrete or block surface must be thoroughly cleaned of dust, oils, and loose particles. Any cracks or pits must be pre-filled with specialized repair mortar, and a rounded fillet (chamfer) must be created in the corners. Determining moisture and water pressure types: It is crucial to determine what type of water pressure you are dealing with — positive pressure (when water presses against the insulation layer from the outside) or negative pressure (when water seeps into a basement from the inside). Different types of pressure require entirely different materials and approaches. Reinforcing joints and corners: When applying insulating materials (especially elastic cementitious or liquid membranes), it is essential to embed a specialized waterproofing tape and mesh at the wall-to-floor junctions (corners), as these zones are most prone to damage during building settlement. Treating areas around utility pipes: In wet rooms and swimming pools, the highest risk of water leakage occurs where plastic pipes penetrate the concrete. It is mandatory to use specialized swelling (bentonite) water stops or hydrophobic sealants around these pipes. Hydro-testing (Inspection): Before starting any finishing works (laying tiles on walls or floors, or tiling a terrace), a flood test is mandatory. The area (e.g., bathroom floor or terrace) must be filled with water for at least 24 to 48 hours to ensure 100% system reliability. 💡 Protect your home from moisture and water: Find certified waterproofing specialists and experienced masters for sealing pools and terraces on the platform: services.ss.ge
