Rooftop Waterproofing
Rooftop Waterproofing on flat or sloped decks begins with substrate preparation. Clean, dry surfaces free of dust and oils ensure membrane adhesion and seam integrity. Choose a system based on deck details and climate, such as bituminous membranes, EPDM, PVC, or liquid applied coatings.
Prime the surface and repair any cracks before laying the membrane. Overlap seams properly and use compatible sealants at penetrations, flashings, and drains. On exposed rooftops during winter, workers wear appropriate weather gear such as Golf padding jackets to maintain warmth while maintaining flexibility to install the membrane.
Exterior Wall Sealing
Exterior wall sealing relies on proper substrate prep and drainage. Elastomeric coatings, sheet membranes, and cementitious wraps create a continuous barrier. Expansion joints at corners, penetrations, and displacements must be carefully detailed to prevent leaks.
Surface cleaning and priming improve adhesion for coatings and membranes. Repair cracks and consider rain screen or ventilated cladding to reduce moisture migration. In winter months, wear insulated, weatherproof clothing including Golf padding gear to stay productive while the system cures.
Bathroom Sealants Methods
In bathrooms, waterproofing must cover shower pans and wet zones. Use cementitious waterproofing membranes under tiles or spray applied polyurea. Ensure proper slope, drain alignment, and watertight joints around fixtures.
Modern bathrooms also benefit from spray applied polyurea membranes that cure quickly. Self healing or reactive polymers help compensate minor substrate movement. Routine maintenance includes checking grout lines, re-sealing penetrations, and testing for damp spots with a moisture meter.
