Rooftop Waterproofing
Rooftop environments face intense sun, rainfall, and temperature swings that challenge any membrane. Selection should consider UV resistance, elongation, and compatibility with roof substrates like concrete or metal. Common options include EPDM, TPO, and bituminous membranes, each with pros and installation nuances.
Proper roof edge detailing and flashing are critical to prevent water seepage at penetrations. Before installation, the surface must be cleaned, dried, and primed, with joints reinforced where required. After installation, perform a hydrostatic test or water ponding test to verify seam integrity.
Exterior Wall Waterproofing
Exterior walls are the first line of defense against moisture intrusion. Choose barrier coatings, cementitious waterproofing, or membrane systems based on substrate and climate. Ensure proper crack management and drainage to prevent capillary action from driving water inward.
Application begins with surface preparation, cleaning, and repairing any cracks. Prime the substrate to improve adhesion and follow with the selected membrane system, ensuring overlaps and detailing at corners. Use reinforcement fabrics over vertical joints and around openings to increase durability. After cure, perform a water test on exterior walls, using spray or capillary tests.
Bathroom Waterproofing
In bathrooms, moisture is constant and spills are frequent. Use waterproof backer boards, a reliable pan liner or liquid applied membrane, and properly sealed joints around showers and vanities. Select moisture resistant tiles and sealants with compatible grout.
Install proper drainage and slope in wet areas to channel water toward drains. Seal all joints at corners, niches, and transitions with compatible sealants and membranes. After setup, perform a shower test with low pressure water and inspect for leaks.
Maintenance and Trends
Maintenance should be scheduled after heavy rainfall and seasonal changes. Inspect roofing joints, wall penetrations, and bathroom seals for cracks or bulges. Clean gutters and drainage paths to prevent water backup.
Guro leak detection services are increasingly integrated with waterproofing to protect basements. These sensors alert property managers before visible damage, reducing costly repairs. Eco-friendly, low-VOC products and self-healing polymers are expanding material options.
