Frequently Asked Questions
Polyurethane (PU) injection is an advanced, non-destructive waterproofing grouting technique. Hydrophobic or hydrophilic liquid resin is pressure-injected into concrete cracks and voids. When PU resin comes into contact with moisture, it expands exponentially to form a flexible, dense foam seal that stops active water leaks permanently.
When high-pressure PU resin is injected into wet concrete cracks, it undergoes a rapid chemical reaction with water, expanding up to 10–30 times its original liquid volume. The expanding foam fills even the smallest microscopic voids and seals off all water pathways instantly within minutes.
PU injection is a 100% non-invasive method that requires no noisy hacking, tile removal, or heavy construction mess. It saves time and labor costs, completes in a single day, and targets hidden water leaks directly within the slab without damaging wall finishes.
Yes. High-pressure PU injection equipment can overcome high hydrostatic water pressure. It is the preferred professional solution for stopping active water inflow in underground basements, retaining walls, swimming pools, concrete water tanks, and lift pits.
Yes, once fully cured, PU foam remains flexible and elastic. Unlike rigid cementitious grouts, flexible PU resin expands and contracts with natural thermal changes and minor building vibrations without cracking or breaking its waterproof seal.
Our specialists locate the crack, drill small port holes at 45-degree angles along the crack line, and insert mechanical injection packers. PU resin is then injected under high pressure until the crack is filled. Afterwards, ports are removed, and holes are sealed flush and smooth.
Most standard residential wall or ceiling PU injection treatments take between 2 to 5 hours. The fast reaction time of polyurethane allows the leak to be sealed immediately during the same visit.
No. Once grouting is complete and injection packers are removed, we patch the small drill entry points with high-strength non-shrink mortar and skim coat. After smooth sanding and touch-up painting, the wall surface looks completely restored.
Pricing is calculated based on the number of injection ports required, linear crack length, and water pressure severity. We offer free on-site inspections and technical assessments to provide clear, transparent quotes with no hidden charges.
We provide a written warranty of up to 5 years for all our PU injection grouting treatments. If any water seepage recurs in the treated injection zone during the warranty period, our technical team will re-inspect and rectify it free of charge.
