Construction solution
Roof Waterproofing
Protect concrete and sheet roofs against water ingress using properly specified waterproofing and joint-sealing systems.
Solution overview
Understanding the application.
Nia Build provides waterproofing solutions for concrete roofs, flat roofs and sheet-roof systems. We assess the roof condition, leakage points, joints, penetrations, drainage and exposed surfaces before recommending a suitable waterproofing system for long-term protection.
Common signs
What may be happening.
Ceiling leaks, water stains, damp patches, failed roof coatings, cracks, leaking fasteners, open sheet overlaps, deteriorated joints and water ponding.
Assessment & considerations
Understand the conditions first.
Roof type, existing waterproofing, substrate condition, cracks, penetrations, joints, drainage falls, outlets, sheet fasteners, overlaps, UV exposure and areas of standing water should be assessed.
Solution approach
Select an appropriate system.
Prepare and repair the roof substrate, treat cracks, joints and penetrations, then install the specified waterproofing system with careful detailing at vulnerable areas such as outlets, upstands, parapets and roof-to-wall junctions.
