Construction solution
Basement Waterproofing
Protect below-ground structures against groundwater, seepage and moisture penetration.
Solution overview
Understanding the application.
Basement waterproofing requires a system designed for below-ground exposure and the specific conditions surrounding the structure. Nia Build provides solutions for basement walls, retaining structures, floor slabs, construction joints and penetrations to help control water ingress and protect below-ground spaces.
Common signs
What may be happening.
Water seepage, damp basement walls, wet floor-to-wall junctions, staining, efflorescence, leaking joints, cracks and persistent below-ground moisture.
Assessment & considerations
Understand the conditions first.
Consider groundwater exposure, drainage conditions, water pressure, structural cracks, construction joints, penetrations, substrate condition and whether waterproofing can be applied from the positive or negative side.
Solution approach
Select an appropriate system.
Prepare and repair the substrate, treat cracks, joints and penetrations, then install a waterproofing system appropriate to the structure and water exposure. Detailing at construction joints and wall-to-floor junctions is particularly important.
