Rooftop Waterproofing
Rooftop areas are exposed to sun, rain, and temperature swings, making durable waterproofing essential. Common methods include flexible membranes and cementitious coatings that form a continuous barrier against moisture. Choosing a method depends on roof type, slope, and the presence of equipment like hot water distribution manifolds in rooftop enclosures.
Before applying any system, the surface must be clean, dry, and free of oils or dust. Surface preparation often involves cleaning, sanding, and applying a primer to improve adhesion. For cracks and joints, detailing with fabric reinforcement or sealant tapes ensures long lasting performance. If cracks exist, cementitious waterproofing or membrane overlays provide robust sealing.
Exterior Wall Sealing
Exterior walls face constant exposure to rain and wind, so sealing must accommodate movement. A combination of cementitious waterproofing and exterior silicone sealants often yields reliable performance. Where cracks form, waterproofing injection or crack bridging membranes can stop moisture from penetrating.
During installation, joints around windows and balconies require careful detailing to avoid water bypass. Material choice depends on substrate, climate, and maintenance expectations, with silicone offering flexibility. Exterior silicone (외벽실리콘) provides durable, flexible sealing at expansion joints and corners.
Bathroom Waterproofing
Bathrooms demand tight moisture barriers behind tiles, especially in showers and wet rooms. A typical approach uses a waterproofing membrane on walls and floors, followed by proper slope and drain details. Waterproofing should extend into niches and corners to reduce hidden leaks and mold risk.
Choose membranes that resist humidity and chemical cleaners, with attention to compatible adhesives. If the bathroom houses a hot water distribution manifold, sealants around pipe entries must be tight to prevent leaks. Epoxy grout or flexible tile adhesives help maintain a robust finish over time.
Maintenance and Upgrades
Regular inspection after heavy rain or seasonal changes helps catch hidden leaks early. Reapply sealants around penetrations and windows when joints show cracking or silicone loses elasticity. Keep drainage paths clear and check roof gutters to prevent ponding that burdens waterproof layers.
Upgrading to advanced coatings or retrofit membranes can extend service life with less downtime. Consider upgrading piping runs around mechanicals with insulated routes to reduce condensation and moisture exposure. For homes with a hot water distribution manifold, plan maintenance that minimizes moisture around pipes and avoids thermal shock to seals.
