Balcony Leak Sealing
On balconies, balcony leakage often starts at joints and drainage paths. Poor slope, clogged weep holes, and aging membranes allow water to penetrate beneath coatings. Early signs include damp patches, efflorescence, and peeling finishes. Proper inspection helps identify hidden weaknesses before water finds a route.
Preparation is essential before applying any waterproofing layer. Clean and dry surfaces, repair cracks, and address movement joints with compatible sealants. Choose a system that matches the substrate, climate, and expected traffic on the balcony.
Liquid membrane systems provide seamless coverage for irregular shapes, while sheet membranes offer robust protection in critical areas. Cementitious coatings cure quickly and are easy to apply on concrete slabs. For balconies with movement, install expansion joints and edge drains to direct water away.
Exterior Wall Sealant
Exterior wall surfaces interact with wind-driven rain, making flashing and proper detailing crucial. Cracks near balconies or window openings invite water intrusion if not addressed. A reliable sealant must flex with temperature changes and maintain adhesion over time.
Elastomeric coatings form a breathable yet waterproof layer on concrete or brick, reducing surface cracking. Polyurethane and silicone-based products provide excellent adhesion on complex profiles but require proper curing conditions. Cementitious waterproof coatings offer durable protection for below-grade or exposed walls. Ensure compatibility with paints, primers, and tile adhesives used nearby to avoid delamination.
Trends include breathable, nano-enhanced coatings that repel water while allowing vapor migration. Smart moisture sensors embedded in some membranes help flag leaks early. Regular inspections and a maintenance schedule extend the life of exterior waterproofing.
Bathroom Waterproofing
Bathrooms present the most challenging wet zones, with constant splash around showers and tubs. Install a reliable waterproofing membrane behind tiles that forms a continuous barrier against moisture. Avoid thin repaints and rely on proven cementitious or sheet membranes specially designed for showers.
Plan water isolation around the shower enclosure, pan, and floor edges, ensuring proper slope toward drains. Behind tile, apply a liquid-applied or sheet membrane with a suitable primer to improve adhesion. Create clean joints with corner beads and compatible sealants at transitions to prevent grout cracking. Cure times and testing procedures must be followed to confirm full waterproof performance before tiling.
Post-installation maintenance is essential to prevent latent leaks, so inspect caulked joints and grout lines annually. Look for hairline cracks, settled floor tiles, or efflorescence on adjacent walls that may indicate a leak. If you detect moisture, re-seal vulnerable joints promptly and consider a professional assessment for hidden paths.
