Service Overview
Professional Crack Waterproofing in Rajahmundry
Cracks in walls and concrete are open doorways for water. As water enters, it erodes cement, corrodes steel rebars, and spreads dampness across the building. Crack waterproofing uses high-pressure resin injection and flexible elastomeric polymers to seal cracks permanently.
When is this service required?
When structural fissures, wall expansion joints, or brick-to-column junctions allow water to pass through.
Common Property Situations
- Settlement cracks in multi-tier buildings in Morampudi.
- RCC beam-column junction cracks in Danavaipeta apartments.
- Water retaining wall cracks in basements and underground tanks in Lalacheruvu.
Preparation & Execution
- Assessing crack depth and whether it is active (moving) or dormant (static).
- Drilling and inserting high-pressure mechanical injection packers.
- Pumping hydrophobic polyurethane expanding resin to fill the entire crack depth.
Types of Cracks We Waterproof
Deep RCC cracks leaking water actively in basements or retaining walls.
Plaster settlement cracks on exterior facade elevations.
Separation cracks between brick masonry and concrete frames.

Answers Before You Book
Frequently Asked Questions
What is high-pressure polyurethane crack injection?
We drill holes at 45-degree angles to intersect the crack, insert brass packers, and inject liquid polyurethane under high pressure. On contact with water inside the crack, the resin expands rapidly into a closed-cell waterproof foam that seals the void.
Can crack waterproofing stop water leaking into basements?
Yes! High-pressure PU injection is the gold standard worldwide for stopping active water leaks in underground concrete basements and retaining walls.
Does crack waterproofing make the wall structurally strong again?
Epoxy resin injection restores structural tensile strength, while flexible polyurethane injection provides elastic waterproofing for moving cracks.
How long does high-pressure injection take to cure?
PU expanding foam reacts and seals within minutes, achieving full cure in 2 to 4 hours.
