What We Offer

Complete Waterproofing & Structural Services

From residential homes to critical national infrastructure - our certified team delivers proven solutions for every waterproofing and structural challenge.

Anti Carbonation Coating

Anti Carbonation Coating

Anti-carbonation coatings are specialized treatments applied to concrete surfaces to prevent carbon dioxide from penetrating the concrete matrix. This process, known as carbonation, lowers the pH of concrete and leads to rebar corrosion and structural failure. Our certified coatings create a breathable yet impermeable barrier that prevents carbonation while allowing moisture vapor to escape.

Key Applications

High-rise buildingsBridges & flyoversParking structuresIndustrial facilities
Waterproofing Solutions

Waterproofing Solutions

Our waterproofing solutions cover all structural zones - from terrace and roof waterproofing using advanced polyurethane and cementitious systems, to basement waterproofing using crystalline and membrane technologies. Bathroom waterproofing is handled with fast-cure, tile-friendly systems that prevent seepage into lower floors.

Key Applications

Terrace & roof slabsBasement & retaining wallsBathrooms & wet areasSunken slabs
Structural Repair & Rehabilitation

Structural Repair & Rehabilitation

Structural repair and rehabilitation involves diagnosing and repairing damage in concrete structures due to corrosion, seismic activity, overloading, or design deficiencies. Our services include concrete jacketing, carbon fiber reinforcement (CFRP), epoxy injection, shotcrete application, and full structural restoration - bringing aging infrastructure back to full structural capacity.

Key Applications

RCC column strengtheningBeam & slab jacketingFoundation repairIndustrial structures
Water Repellant & Anti Graffiti Treatment

Water Repellant & Anti Graffiti Treatment

Silicone-based water repellants penetrate deep into masonry and concrete surfaces, creating an invisible hydrophobic barrier that repels water while maintaining the natural appearance of the substrate. Anti-graffiti coatings protect facades and surfaces from paint, markers, and other vandalism - enabling easy cleaning without damage to the underlying surface.

Key Applications

External facade treatmentHeritage buildingsMetro & transit infrastructureCommercial complexes
Thermal Insulation (Roof & External Facade)

Thermal Insulation (Roof & External Facade)

Our thermal insulation systems for roofs and external facades significantly reduce heat transfer, lowering indoor temperatures and HVAC loads. We use high-performance EPS, XPS, polyurethane foam, and reflective systems - all applied by certified technicians with proper vapor barrier integration to prevent condensation buildup.

Key Applications

Flat roofs & terracesCold storage facilitiesExternal EIFS systemsIndustrial warehouses
Expansion Joints, Control Joints & Fire Barriers

Expansion Joints, Control Joints & Fire Barriers

Expansion and control joints are critical for accommodating structural movement caused by thermal expansion, seismic activity, and settlement. We design and install bespoke joint systems using proven materials including polysulfide sealants, polyurethane sealants, and pre-formed compression seals. Fire barrier systems are installed in compliance with fire safety codes.

Key Applications

Bridges & flyoversMulti-storey car parksIndustrial floorsTunnel linings
Bearing Replacement & Lifting of Span/Girders

Bearing Replacement & Lifting of Span/Girders

Bridge bearings are critical components that transfer loads from the superstructure to the substructure while accommodating movements. Over time, bearings deteriorate and require replacement to maintain structural safety. Our specialized teams perform controlled hydraulic lifting of bridge spans and girders to replace worn bearings with minimal traffic disruption.

Key Applications

Highway bridgesRailway bridgesFlyovers & viaductsIndustrial gantries
Dam & Tunnel Repair

Dam & Tunnel Repair

Dams and tunnels require specialized repair techniques due to the extreme hydrostatic pressures and environmental conditions they face. Our services include crack injection in tunnel linings, waterstop installation, polyurethane grouting for active leaks, shotcrete applications, and comprehensive dam face repair using waterproof concrete systems.

Key Applications

Gravity & arch damsRoad & railway tunnelsMetro tunnel liningsUnderground structures
Specialized Solutions for Mines

Specialized Solutions for Mines

Mining operations present unique structural and waterproofing challenges due to extreme groundwater pressures, chemical exposure, and demanding access conditions. We provide specialized grouting, waterproofing, and structural repair solutions for mine shafts, adits, portals, and underground structures using materials rated for aggressive environments.

Key Applications

Mine shafts & aditsUnderground chambersProcessing plant structuresTailings facilities
Controlled Dismantling

Controlled Dismantling

Controlled dismantling uses chemical expansion agents, diamond wire saws, and core drilling to selectively remove concrete without the vibration and noise associated with conventional demolition. This method is ideal for structures in urban environments, near sensitive buildings, or where adjacent structures must remain undamaged.

Key Applications

Urban demolitionHeritage structure modificationsBridge deck removalIndustrial plant decommissioning
Hydro Demolition

Hydro Demolition

Hydro demolition uses ultra-high-pressure water jets to selectively remove deteriorated concrete while leaving intact rebar and sound concrete undisturbed. This technique is superior to mechanical demolition as it creates a rough bonding surface ideal for repair overlays, produces no micro-cracks, and significantly improves the bond of new repair materials.

Key Applications

Bridge deck rehabilitationParking garage repairsDam face preparationTunnel lining removal
Injection Grouting & Building Restoration

Injection Grouting & Building Restoration

Injection grouting involves injecting cementitious, epoxy, or polyurethane grout under pressure into cracks, voids, and cavities in concrete and masonry structures. This technique seals active water leaks, strengthens weakened zones, and restores structural integrity. Building restoration combines grouting with surface treatment, repointing, and facade repair for complete structural renewal.

Key Applications

Active crack sealingFoundation stabilizationHeritage building restorationPost-tension slab repair
