Leak sealing
PU Injection (Cracks & Joints)
Stops active water seepage in basements, lift-pits, tanks and slabs by pressure-injecting expanding PU resin.
Process — 5 steps
- Mark leak lines → drill packer points at 45°
- Fix mechanical packers and flush
- Inject hydrophilic/hydrophobic PU under pressure
- Resin expands and blocks water pathways
- Remove packers → patch and finish
Materials we use
PU resin (fast/slow set), mechanical packers, injection pump, polymer-modified mortar for finishing.
FAQs
- How long does it last? Many years if movement is minimal; cracks that move may need a top sealant joint.
- Can you inject during active leakage? Yes, we use fast-foaming resin for live leaks.
- Will it stain the wall? Holes are patched; only tiny dots remain.
Structural
Epoxy Grouting (Honeycombs & Voids)
Binds cracked RCC and fills voids to restore strength around beams, columns and slabs.
Process — 5 steps
- Crack mapping & core check
- Surface sealing and port fixing
- Low-viscosity epoxy injection
- Curing & port removal
- Reprofiling and finishing
Materials
LV epoxy systems, surface sealer, injection ports, grinder, PPE.
FAQs
- Is it waterproofing? It’s structural. For leakage we combine with PU or surface systems.
- Any downtime? 24–48 hours typical.
Below grade
Basement Waterproofing
Stops ground water ingress through retaining walls and raft junctions using injection + negative-side coatings.
Process — 5 steps
- Leak diagnosis & salt removal
- PU injection at active seams
- Crack chasing & polymer mortar
- Crystal growth/elastic coating (2–3 coats)
- Fillet coves & protective top coat
Materials
PU resin, crystalline slurry, elastomeric coat, primers, polymer mortar.
FAQs
- Will the salt bloom return? Not after proper neutralisation and coating system.
- Do you need outside excavation? Usually no; we treat from inside.
Decks
Podium Waterproofing
Seamless membranes under tile/landscape areas with proper slopes and drain detailing.
Process — 5 steps
- Substrate prep & slope correction
- Primer & detailing at drains upstands
- PU/Acrylic membrane in multiple coats
- Protection screed
- Tile/finish installation
Materials
PU/Acrylic membranes, geotextile at joints, primers, bond coats.
FAQs
- Movement cracks? We add joints and mesh to control them.
Commercial
Commercial Shade Waterproofing
Seals leaks at MS sheds and polycarbonate roofs with UV-stable sealants and coatings.
Process — 5 steps
- Nut-bolt & overlap sealing
- Rust treatment
- PU sealant for joints
- UV roof coat application
- Final inspection under water spray
Materials
PU sealant, butyl tapes, anti-rust primer, UV reflective coats.
FAQs
- Heat reduction? Yes, reflective coats drop surface temp noticeably.
Terraces
Roof/Terrace Waterproofing
Long-life membrane systems that bridge cracks and handle ponding with correct slope and outlets.
Process — 5 steps
- Surface cleaning & crack cutting
- Polymer repair mortar
- Primer + 2–3 coats elastomeric membrane
- Fabric reinforcement at critical areas
- Topcoat/tiles as per design
Materials
Acrylic/PU membranes, polyester fabric, primers, reflective topcoats.
FAQs
- Can we walk on it? With topcoat yes; heavy use needs tiles or screed.
Potable-safe
Overhead/UG Tank Waterproofing
Food-grade coatings and joint sealing for leak-proof, hygienic water tanks.
Process — 5 steps
- Drain, clean, remove algae
- PU injection at live leaks
- Patching & coves
- Food-grade coating (2–3 coats)
- Final wash & refill after cure
Materials
NSF/IS-approved coatings, PU resin, polymer mortar.
FAQs
- Is water safe? Yes, we use potable-safe systems after full cure.
Finishing
Crack Filling & Sealant Joints
Treats shrinkage cracks and movement joints to stop seepage and paint failure.
Process — 5 steps
- V-groove cracks
- Dust removal & primer
- Polymer putty or sealant filling
- Mesh at wide areas
- Finish & repaint
Materials
Acrylic/PU sealants, fiber mesh, bonding primer, exterior putty.
FAQs
- Will cracks return? Movement joints need flexible sealant and may need periodic checks.
Source fix
Plumbing Leak Detection & Repair
We locate and fix pipe leaks, faulty traps and joints that cause damp patches and seepage.
Process — 5 steps
- Pressure & dye tests
- Chasing with minimal breakage
- Pipe/joint replacement
- Waterproof detail at chases
- Replaster & tidy finish
Materials
UPVC/CPVC fittings, valves, primers, polymer mortar, sealants.
FAQs
- Can you do night work? Yes on request for commercial sites.
