Specialized Civil & Waterproofing Services.
From deep subterranean basement membrane tanking to polyurethane pressure crack injection and structural CFRP column strengthening. Audited under ISO 9001:2015 standards with institutional 10-year warranty SLAs.
Waterproofing Services (Basements, Roofs & Podiums)
Turnkey installation of multi-layer below-grade tanking systems using APP/SBS modified bituminous membranes, pre-applied HDPE waterproofing, and crystalline coatings designed to resist hydrostatic heads exceeding 30 meters.
- Key Applications: Deep Raft Basements, Retaining Walls, Podium Expansion Slabs, RCC Water Tanks.
- Warranty SLA: Stamped 10-Year Corporate Performance Guarantee.
Waterproofing Repairing & PU Pressure Grouting
Remedial structural rehabilitation for actively leaking underground basements, elevator pits, and tunnels using high-pressure single and dual-component Polyurethane (PU) hydrophobic injection resins that seal running water within 90 seconds.
- Key Technologies: 250 Bar Mechanical Injection Packers, Hydrophobic PU Grout, Low-viscosity Epoxy.
- Advantage: 100% Non-destructive repair with zero structural dismantling required.
Construction-Related Services & CFRP Retrofits
Structural capacity upgrades for overloaded columns and distressed beams using Carbon Fiber Reinforced Polymer (CFRP) fabric wrapping, micro-concrete encasement, heavy-duty industrial epoxy screeds, and expansion joint elastomeric bridge profiles.
- Compliance: ACI 440.2R Guidelines & ASTM D3039 Tensile Standards.
- Services Included: Epoxy floor coatings, joint coring, rebar anchoring.
Product Consultation & Chemical Specification
Our qualified materials engineers review tender specifications, soil bore reports, and concrete mix designs to prescribe the optimal balance of plasticizers, silica fumes, and membrane chemistries that prevent chemical over-expenditure while ensuring total structural protection.
- Deliverables: Stamped Bill of Materials, Mix Design Trials, Comparative Cost Analysis.
- Turnaround: Comprehensive specification report delivered within 24 hours.
Technical Assistance & On-Site QA Supervision
Even the best chemical formulations fail if improperly applied. Rajguru provides on-site application engineers who calibrate surface preparation, verify substrate moisture levels (RH < 4%), conduct pull-off tensile adhesion tests, and train your workforce in torch-on seam welding.
- Testing Protocols: Substrate Moisture Meters, Adhesion Testers, Holiday Spark Testers.
- Certification: On-site QA Inspection Sign-off Logs for Client Consultants.
Project-Based Services & MoRTH Road Markings
Turnkey execution of automated thermoplastic road markings conforming strictly to MoRTH Section 803, highway retro-reflective signboard fabrications, expansion joint sealing on bridges, and acoustic barrier installations for highway and expressway projects.
- Machinery: Automatic Screed Thermoplastic Applicators & Glass Bead Dispensers.
- Standards: Retro-reflectivity > 250 mcd/m²/lux conforming to IRC 35.
