Waterproofing fundamentals
Waterproofing shields buildings from moisture intrusion and leakage. Choose compatible materials for substrates, joints, and penetrations to ensure lasting performance. Early surface preparation and proper priming set the foundation for a durable seal.
Assess climate, movement, and exposure to select the right membrane type. Common options include liquid-applied coatings, sheet membranes, and cementitious systems. Proper detailing at edges and around fixtures prevents hidden leaks.
Rooftop waterproofing
Rooftop waterproofing must address slope, drainage, and UV exposure. Choose membranes that resist punctures and allow for thermal movement. Detail penetrations, vents, and parapets with integrated flashings to prevent leakage.
Install on a clean, dry surface and follow curing times precisely. Sheet membranes may require seam bonding and liquid systems offer seamless benefits. Regular inspections after heavy rain reveal early signs of capillary leakage.
Bathroom waterproofing
Bathroom waterproofing must include wet area details and containment. Use cementitious or polymer-modified coatings suitable for high humidity. Guard around showers, bases, and niches with sloped surfaces and membranes.
Select non-porous tiles, proper grout, and sealants that tolerate joint movement. Integrate waterproofing underlays and backer boards behind tiles for mold resistance. Inspect seams and corners regularly and reapply sealant when signs of leakage appear.
