Trusted by Leading Builders, Government Projects & 35+ Organizations Across Delhi NCR
20+ Years of Engineering Competence Over Corporate Hype
Founded and managed by Mr. Shailendra Kumar Jha, S.K. Enterprises ("Drop Fix") is a specialized waterproofing contractor and full-service civil repair agency based in Dwarka, New Delhi.
Over the last two decades, our enterprise has earned a reputation for diagnosing the exact root cause of complex water ingress in residential kothis, housing societies, institutional complexes, and large-scale industrial structures across Delhi NCR. We do not apply generic surface coatings that peel off after a single monsoon — we formulate and execute engineered barrier systems tailored to the hydrostatic pressure and structural behavior of each site.
Core Quality Policy & Property Protection
Specialist Waterproofing & Allied Civil Engineering
We operate in two specialized divisions: Core High-Performance Waterproofing Systems, and Turnkey Civil Rehabilitation. Select a category below to explore technical solutions:
Roof & Terrace Waterproofing
High-tensile seamless liquid membranes, APP torch-on membranes, and elastomeric UV-reflective coatings that accommodate building thermal expansion without cracking.
Balcony & Chajja Waterproofing
Slope correction, drip groove creation, and perimeter edge sealing to stop water from tracking back into bedroom ceilings, external walls, and windows.
Toilet & Sunken Slab Waterproofing
Deep multi-coat polymer slurry treatment for sunken slabs, drain trap pipe sleeves, and sanitary wall surfaces to halt moisture seepage into adjacent rooms.
Terrace Garden Waterproofing
Anti-root penetration barriers, geotextile filtration layers, dimpled drainage cells, and chemical-resistant membranes engineered for green roofs and planter boxes.
Basement Waterproofing (Positive & Negative)
Specialized crystalline waterproofing and capillary-blocking chemical systems for basements facing high groundwater tables. Stops rising dampness from the inside without excavation.
Raft & Foundation Waterproofing
Comprehensive blindside membrane installations and pre-applied HDPE waterproofing sheets for substructure raft slabs to resist active hydrostatic water pressure.
Water Tank & Swimming Pool Proofing
Non-toxic, potable-safe, certified drinking water tank coatings and elastic swimming pool membranes that withstand severe positive water pressure and continuous chlorine exposure.
Pressure Injection Grouting & Crack Sealing
Immediate mechanical stoppage of live, gushing water leaks using high-pressure single/dual component polyurethane (PU) expanding resins and low-viscosity epoxy grouts.
Expansion Joint Waterproofing
Engineering treatment of building separation and expansion joints using vulcanized Hypalon/TPE joint bandage tapes, closed-cell backing rods, and heavy-duty polysulphide sealants.
Kota Stone, Brick-Bat-Coba & Grouting
Classical density slope-grading and masonry protection integrated with modern chemical polymer mortars. Re-pointing, joint resetting, and slurry injection for aging terrace beds.
Vermiculite & Thermal Roof Insulation
Lightweight expanded vermiculite screeds and extruded polystyrene (XPS) thermal insulation boards that slash indoor ceiling temperatures by 5°C to 8°C in Delhi NCR summers.

Carbon fiber reinforced polymer (CFRP) wrapping and steel plate jacketing for beams, columns, and slabs requiring seismic enhancement or additional floor load capacity.
Gunniting & Shotcrete Solutions
High-pressure pneumatic projection of dense concrete mortar onto prepared wire mesh reinforcement. Ideal for deep pool walls, retaining walls, and subway embankments.
Silicone & Acrylic Weatherproof Painting
External breathable, elastomeric facade coatings that prevent wind-driven rain penetration while allowing interior humidity to escape freely without bubbling.
Plastering, Tiling & Turnkey Civil Works
Complete internal and external civil repair, precision screed leveling, vitrified and ceramic tile installation, false ceilings, and post-leakage interior restoration.
Why Property Owners & Developers Choose S.K. Enterprises
Most waterproofing contracts fail because big brands send salespersons rather than civil applicators. Here is how our 20-year on-site discipline guarantees results:
20+ Years Field Experience
Extensive hands-on execution on MNC construction projects, high-rise residential towers, and ultra-luxury Delhi kothis. We know Delhi NCR soil, water tables, and thermal stress.
Root-Cause Engineering Diagnosis
We never paint over blistering paint or apply cosmetic whitewash. We identify hydrostatic pressure points, pipe penetrations, and expansion shear before recommending a solution.
Trained In-House Application Crew
Application is 80% of waterproofing success. Our full-time technicians are trained in chemical mixing ratios, surface preparation, primer cure times, and DFT thickness.
Engineered Chemical Selection
We diagnose each structure independently and specify high-grade polymers, polyurethane elastomers, and crystalline systems matching the hydrostatic load — never forcing a single generic coating.
Direct Contractor Pricing
Deal directly with the master contractor. Cut out agency commissions, corporate sales rep margins, and franchise fees. Save 30% to 40% with superior jobsite accountability.
100% Quality Inspection & Warranty
Every terrace and sunken area is pond-tested under continuous water load. We issue clear written warranties backed by our 20-year standing reputation in Delhi NCR.

Technical Project Overview
Frequently Asked Questions
Honest, technical guidance to help you make informed decisions about your building's waterproofing and civil rehabilitation.
Waterproofing failures usually occur for three reasons: (1) Surface-level painting over dirty, dusting concrete without proper grinding and priming; (2) Using rigid, cheap cementitious coatings that cannot withstand the extreme thermal expansion of Delhi summers, causing microscopic cracking; and (3) Unskilled labor rushing application without respecting mandatory dry-film cure times. S.K. Enterprises uses high-elongation elastomeric membranes and deep-penetrating primers applied strictly by trained in-house personnel.
Yes! We offer specialized non-destructive waterproofing solutions. If existing tiles are structurally sound, we cut and re-grout tile joints using high-strength flexible epoxy polymer grouts, followed by applying an aliphatic UV-stable transparent polyurethane membrane. This forms an invisible, 100% water-impermeable shield over your tiles without the noise, debris, and huge expense of dismantling.
Negative-side waterproofing treats the inside surface of basement walls and retaining slabs. We apply proprietary crystalline chemical compounds. When applied to damp concrete, active chemicals react with free lime and moisture inside the concrete to grow insoluble microscopic crystals deep within the concrete's capillaries. These crystals permanently block water pores even against severe hydrostatic head pressure from outside groundwater.
Yes. For residential kothis, housing societies, commercial plazas, and industrial units across Dwarka, Janakpuri, Najafgarh, Gurugram, Noida, and greater Delhi NCR, Mr. Shailendra Kumar Jha's engineering team provides a zero-obligation on-site assessment. We physically inspect your roof, basement, or damp walls and provide a comprehensive written specification.
Pressure injection grouting is the gold-standard engineering method to stop active water gushing through RCC cracks, honeycombing, or construction cold joints. We drill angled holes across the crack line, install high-pressure mechanical packers, and pump low-viscosity hydrophobic polyurethane resin at up to 250 bar pressure. Upon contact with water, the resin reacts and expands up to 20 times its volume, creating a tough, elastic rubber seal that permanently plugs the water channel.
All our comprehensive waterproofing treatments come with a formal written service warranty backed by mandatory 48-hour continuous water-ponding tests. Having operated in Delhi NCR for over 20 years with prestigious corporate clients like Birla Estates, NTPC, and Punj Lloyd, our reputation and local physical presence in Dwarka ensure you get genuine after-service support.
