Require Waterproofing Estimate?
Contact our senior chemical engineers for site surveys, moisture testing, and specification drawings.
Contact Technical TeamSpecialized Injection Grouting Systems
ASR Engineers & Developers specializes in advanced injection grouting methodologies across metro tunnels, deep basements, expressway retaining walls, and hydro projects. We deploy four dedicated chemical formulations:
PU Grouting (Polyurethane)
High-pressure hydrophobic/hydrophilic polyurethane resins that react instantly upon contact with water, expanding up to 20 to 30 times their original liquid volume to form a resilient, flexible, closed-cell foam gasket that permanently arrests active flowing leaks through cracks, cold joints, and honeycombs.
Cement Grouting (Microfine & Ultrafine)
Formulated with ultra-fine particle size cements and non-shrink fluidifying plasticizers. Enables deep penetration into hairline fissure networks, rock mass stratas, soil consolidation zones, and porous concrete matrices where normal Portland cement cannot enter.
Epoxy Grouting
Ultra-low viscosity, solvent-free epoxy resins injected under controlled pressure into dry or damp structural cracks. Restores monolithic structural integrity with tensile and compressive strengths significantly exceeding the parent concrete.
Acrylic Gel Grouting
Water-like viscosity acrylic gel formulations designed for curtain grouting behind subterranean tunnel liners, masonry retaining walls, and soil strata stabilization. Creates an impermeable elastic rubber-like barrier against moisture.
All Services
Active Water Leakage?
Our emergency injection grouting crews mobilize promptly to arrest basement and retaining wall leakages.
Contact Technical TeamSpecialized Industrial Coating Systems
Civil structures exposed to carbon dioxide, airborne chlorides, industrial chemicals, and wastewater require specialized barrier coatings. We deliver three critical formulations:
Food Grade Coating
Solvent-free, non-toxic, and certified safe for contact with potable drinking water, food processing surfaces, grain silos, and institutional cleanrooms. Prevents bacterial growth while providing an impervious, easily cleanable lining.
Anti-Carbonation Coating
Specialized formulation for Bridges, Fly-overs, Elevated roads & Metro Structures.
Acts as an effective barrier against harmful acid gases like Carbon Dioxide (CO2), Sulphur Dioxide (SO2), and chloride ions while permitting concrete water vapor to breathe outward. Prevents depassivation of internal rebar and premature spalling in urban transport corridors.
Epoxy Coating (High Chemical Resistant with Novolac Resins)
Novolac epoxy resin coatings engineered for chemical processing facilities, battery rooms, containment bunds, and effluent treatment plants (ETP). Delivers extreme defense against concentrated acids, alkalis, solvents, and fuels.
All Services
Elevated Infrastructure?
Consult our technical directors on anti-carbonation specifications for flyover superstructures.
Contact Technical TeamStructural Restoration Methodologies
ASR Engineers & Developers rehabilitates compromised, aged, or overloaded reinforced concrete elements across power plants, bridges, and industrial structures through four core repair technologies:
PMM (Polymer Modified Mortar)
High-strength, non-shrink polymer modified mortars engineered for spalled concrete reprofiling, overhead patch repairs, and structural member rebuilding without sagging. Delivers exceptional bond strength and low permeability to chlorides.
Carbon Wrapping (CFRP Composite Systems)
Carbon Fiber Reinforced Polymer (CFRP) fabric wraps bonded with high-modulus epoxy saturants. Dramatically elevates the flexural, shear, and axial confinement load capacity of concrete columns, beams, and slabs with negligible dead weight addition.
Micro Concrete for Structure Repair
Pre-packed, factory-controlled, non-shrink micro concrete formulations with free-flowing characteristics. Perfect for structural jacketing, heavy cross-sectional restoration of columns and beam encasements where shuttering space is congested.
Fiber Glass Wrapping (FRP)
E-glass and specialized fiber glass composite wraps providing superior electrical non-conductivity, corrosion resistance, and structural confinement for pipes, culverts, marine piles, and industrial tanks.
