Assessing waterproof needs
Waterproofing plans should begin where smoke control equipment is installed, including rooftops and service rooms. Identify leakage paths around penetrations, joints, and cable conduits that could undermine sensors. Consider drainage, capillary rise, and drainage slopes to prevent water buildup.
Choose waterproofing systems with compatibility for electrical rooms and corrosion-prone metal fittings. Assess material resilience against repeated heating and cooling, salt spray, and humidity. Design with accessible interfaces so maintenance crews can inspect seals without disruption.
Rooftop and exterior care
:Rooftop membranes must tolerate sun exposure, temperature swings, and wind-driven rain. Use reinforced sheets or liquid membranes over parapets to guard edge details. Provide proper slope and drainage to direct water away from vent shafts.
Exterior walls with penetrations for ducts and sensors require precise sealants. Choose low-odor, UV-stable polyurethane or silicone products suitable for heavy traffic. Regularly inspect joints, replace aging sealants, and verify bond performance after storms.
Maintenance and trends
Routine inspections reveal early signs of moisture intrusion around equipment enclosures. Incorporate moisture sensors and infrared thermography to target hidden leaks. Document repairs and track sealant ages to plan timely replacements.
Current trends favor hydrophobic coatings and breathable membranes that still block water. Self-healing sealants and smart sensors integrate with building management for proactive alerts. Sustainable materials and modular systems simplify upgrades without tearing finishes.
