FAQ's
While both waterproofing and damp proofing are used to protect structures from moisture, they serve different purposes and offer different levels of protection.
Waterproofing stops water, while damp proofing slows or resists moisture. For areas exposed to water pressure or continuous moisture, waterproofing is the more reliable and durable solution.
- Non-invasive (no need to excavate or expose structure)
- Effective for both dry and wet cracks
- Quick to apply with minimal disruption
- Long-lasting when correctly specified
While mostly used in commercial and industrial applications, PU injection can be used in residential basements or retaining walls, especially where retrofitting is needed.
When correctly applied with the right material for the condition, injection systems can provide long-term waterproofing and structural stability. Regular inspection may still be needed for high-movement areas.
The process typically involves:
- Drilling holes at strategic intervals
- Installing injection packers
- Injecting resin under pressure
- Monitoring for proper material flow and seal
Key factors include:
- Crack width and movement potential
- Presence of water (active or passive leaks)
- Structural vs non-structural repair
- Type of substrate (concrete, masonry, etc.)
- Environmental exposure (chemicals, temperature, etc.)
