The Basement Water Problem
Basements face unique waterproofing challenges:
- Hydrostatic Pressure: Underground water table exerts continuous pressure on walls and floor
- Lateral Seepage: Water migrates through soil and penetrates basement walls
- Capillary Action: Moisture rises through concrete pores
- Construction Joints: Vulnerable points between slab and walls
Scientific Solutions
Positive Side Waterproofing (External)
Applied on outer surface before backfilling. Most effective as it stops water at source. Uses bituminous membrane, liquid membranes, or bentonite clay.
Negative Side Waterproofing (Internal)
Applied on internal walls when external access is impossible. Uses crystalline waterproofing, cementitious coatings, or cavity drainage systems.
Injection Grouting
For existing basements with active leaks. PU injection stops water immediately through expansion and void filling.
Our Basement Approach
- Detailed site inspection & water table assessment
- Identification of active leak points
