URBAN SEAL WATERPROOFING
Basement Waterproofing
Below-grade concrete basement walls are subjected to persistent hydrostatic pressure from surrounding groundwater. Any crack or construction joint will lead to seepage, damp air, structural degradation, and unusable commercial parking or storage areas.
Our Basement Sealing Solutions
- Positive Side Waterproofing: Installation of HDPE dimple drainage boards and elastomeric bituminous membranes on exterior retaining walls during construction.
- Negative Side (Internal) Treatment: Crystalline slurries that react with moisture in concrete to form micro-crystals, blocking capillary pores internally.
- Polyurethane Packer Injection: Pressurized grouting of structural wall joints to stop active water flow.
