Comprehensive waterproofing solutions for industrial rooftops, terraces, basements, underground structures, water tanks, and wet manufacturing areas. CIPY-backed PU membrane, cementitious, crystalline, acrylic, and epoxy waterproofing systems installed by Sri Sai Technologies across India.
In an industrial facility — whether a manufacturing plant, warehouse, pharmaceutical unit, or food processing facility — water infiltration is far more than an inconvenience. It is a direct threat to the building's structural integrity, to production continuity, to product quality, and to the safety of personnel and equipment. Yet waterproofing is often one of the most undervalued elements of industrial construction and maintenance — until the first monsoon season reveals the consequences of inadequate protection.
Water ingress through an industrial roof causes a cascade of problems. Water contacting reinforced concrete causes carbonation and chloride-induced corrosion of the steel reinforcement — a process that begins invisibly and proceeds for years before concrete spalling reveals the extent of the structural damage below. The repair cost of reinforcement corrosion damage — involving concrete breaking out, bar treatment, patch repair, and surface protection — is invariably many times greater than the cost of the waterproofing that would have prevented it. In terms of lifecycle economics, proper industrial waterproofing is one of the highest-return investments a facility manager can make.
Beyond structural damage, water infiltration in an industrial facility causes direct production losses. Water dripping onto process equipment, raw materials, finished goods, or packaging causes product damage, quality failures, and potential product recalls. In pharmaceutical facilities, water ingress into production areas triggers GMP deviation investigations, potential regulatory action, and damage to the facility's product manufacturing licence. In electronics and precision manufacturing, moisture damage to equipment, components, or calibrated instruments can cause significant financial losses. In food processing plants, water ingress creates microbial contamination risks and regulatory non-compliance. The combined cost of production downtime, product losses, regulatory consequences, and equipment damage during a serious water ingress event routinely exceeds the entire waterproofing budget of the facility.
Insurance implications also drive the business case for industrial waterproofing. Many industrial property insurance policies require evidence of adequate maintenance, including waterproofing, as a condition of cover for water damage claims. Facilities that cannot demonstrate regular waterproofing inspection and maintenance may find their claims contested. Sri Sai Technologies provides full documentation of waterproofing works — specifications, application records, test results, and inspection reports — that supports insurance compliance requirements.
Sri Sai Technologies offers a complete range of CIPY-backed waterproofing systems covering every application in the industrial environment — from rooftops and terraces to basements, water tanks, and wet process areas.
The gold standard for industrial rooftop and terrace waterproofing. CIPY PU membrane systems provide exceptional elongation (>300%) to accommodate thermal movement in large industrial roof spans, excellent UV resistance, seamless coverage, and long-term durability. Available as single and two-component systems. Suitable for both new construction and re-waterproofing applications. Up to 10-year warranty on qualifying projects.
Polymer-modified cementitious waterproofing systems for internal wet areas, basement walls, water tanks, and below-grade structures. Easy to apply by brush or spray, bonds directly to concrete and masonry without primer, and can be applied to slightly damp substrates — critical for remedial basement waterproofing works. CIPY cementitious systems offer rigid and flexible formulations.
A revolutionary technology that becomes a permanent part of the concrete structure. CIPY crystalline waterproofing compounds react with concrete's calcium silicates and water to grow insoluble crystals that fill pores and micro-cracks, making concrete permanently impermeable. Self-seals minor cracks and re-activates in the presence of water. Ideal for below-grade concrete structures, water retaining structures, and tunnels.
Elastomeric acrylic waterproofing coatings for rooftops, terraces, parapet walls, and exposed surfaces. CIPY's acrylic systems provide a cost-effective, flexible waterproofing layer with good UV resistance, ease of application, and the ability to bridge minor surface cracks. Available in a range of colours — including heat-reflective white — to reduce cooling loads on industrial buildings.
For wet process areas within industrial facilities — pump rooms, chemical storage bunds, water treatment areas, and podium decks with heavy traffic — CIPY epoxy waterproofing systems provide waterproof protection combined with the mechanical strength needed to withstand vehicle loads and industrial traffic. Seamless, impermeable, and easy to clean.
For active water leaks through cracks and joints in concrete structures — basements, underground car parks, tunnels, and retaining walls — polyurethane foam injection or epoxy injection grouting provides rapid, effective sealing of water pathways. Sri Sai Technologies uses CIPY injection products for both emergency leak sealing and permanent crack waterproofing.
Large-span industrial and factory rooftops subject to heavy thermal cycling, UV exposure, and mechanical stress from maintenance traffic. CIPY PU membrane systems are the preferred specification for long-term performance with minimal maintenance intervention.
Occupied or trafficked terraces, plant rooms with heavy equipment, and utility rooftops where waterproofing must withstand mechanical damage from equipment and maintenance personnel. Epoxy-based or heavy-duty PU systems with protective screed overlay.
Below-grade walls, floors, lift pits, underground car parks, and service tunnels where hydrostatic water pressure from groundwater requires positive-side or negative-side waterproofing systems. Crystalline and cementitious systems for concrete structures.
Overhead water storage tanks, underground sumps, fire water tanks, and effluent tanks. Internal waterproofing lining using CIPY cementitious or epoxy systems — with potable-water-approved grades for drinking water tanks, confirmed with material safety certification.
Boiler rooms, cooling tower bases, pump rooms, effluent treatment areas, and process areas with regular water exposure. Combination of waterproofing membranes with chemical resistant topcoats where process chemicals are also present.
Multi-storey industrial facility podium slabs with traffic above and occupied spaces below. Heavy-duty PU or epoxy waterproofing with root-barrier membranes for green roof applications and protective screed for vehicle-trafficked podium decks.
Prevents water ingress from causing corrosion of steel reinforcement in reinforced concrete structures — the leading mechanism of long-term structural deterioration in industrial buildings. Protects your facility's structural integrity for decades.
Eliminates water ingress events that cause production shutdowns, product damage, and emergency remediation works — protecting revenue and meeting customer delivery commitments.
Sri Sai Technologies offers up to 10-year workmanship warranty on qualifying CIPY PU membrane waterproofing systems — providing long-term assurance for facility managers and asset owners.
Maintains GMP compliance in pharmaceutical facilities, food safety standards in food processing plants, and ISO facility standards that require protection of products, equipment, and personnel from water contamination risks.
Effective waterproofing reduces the ongoing maintenance burden on industrial facilities — eliminating emergency call-outs, patching of failed waterproofing, and remediation of water damage to ceilings, walls, and electrical systems.
CIPY's heat-reflective acrylic waterproofing coatings on industrial rooftops reduce solar heat gain — lowering internal temperatures, reducing air-conditioning loads, and delivering measurable energy cost savings in Indian climate conditions.
All waterproofing systems use CIPY products by Pidilite Industries — India's most trusted construction chemicals brand — ensuring consistent quality, technical data sheet backing, and full technical support throughout the project.
Sri Sai Technologies gives particular attention to critical waterproofing details — drains, upstands, parapet walls, and penetrations — where most waterproofing failures originate. Our installation quality at details is what separates long-lasting from short-lived waterproofing.
Full documentation of all waterproofing works — specifications, material certificates, application records, and inspection reports — supports property insurance compliance and strengthens your position in any water damage claim.
Sri Sai Technologies delivers industrial waterproofing services across India — from large industrial zones in Maharashtra, Gujarat, Telangana, and Tamil Nadu, to remote manufacturing facilities. Rapid mobilization for both planned works and emergency waterproofing situations.

A thorough inspection of the existing structure — rooftop, basement, or water tank — is carried out. Existing waterproofing condition, drainage, structural cracks, water ingress points, and substrate condition are all assessed. A detailed survey report and system recommendation is prepared. For existing waterproofing failures, thermographic imaging may be used to identify the full extent of water ingress beneath the existing membrane.
All existing failed waterproofing, moss, algae, dirt, and loose surface material are removed. Structural cracks are repaired using CIPY repair mortars. The surface is brought to the required profile and condition for the selected waterproofing system. For PU membrane application, the surface must be thoroughly dry and clean. Drainage outlets are inspected and cleared.
Appropriate CIPY primer is applied to the prepared substrate to seal the surface, improve adhesion of the waterproofing membrane, and reduce porosity. Primer selection depends on the substrate type and the waterproofing system to be applied above. Application is by roller or brush, and the primer must be allowed to achieve the specified tack or cure before the next layer is applied.
Before application of the field membrane, all critical details — drains, outlets, upstand junctions, parapet coping junctions, pipe penetrations, expansion joints, and internal corners — receive additional waterproofing reinforcement. This typically involves pre-formed CIPY flashing tapes, fibreglass reinforcement mesh, and additional coats of membrane at these highly stressed locations. Most waterproofing failures originate at details — this step receives our closest attention.
The CIPY waterproofing membrane is applied to the field area in the specified number of coats and total thickness. For PU systems, typically two coats are applied — first coat by squeegee and back-roller, second coat at 90° to the first. Wet film thickness is monitored throughout using wet film thickness gauges. Application proceeds methodically to ensure complete, uniform coverage without pinholes or thin areas.
For exposed rooftop membranes, a UV-resistant topcoat is applied. For trafficked areas, a protective screed or anti-slip aggregate finish coat is applied. For the most exposed locations, aluminium-faced or granule-topped finish coats provide maximum UV protection and durability. The choice of topcoat depends on the application area's traffic level and UV exposure.
Finished waterproofing is tested using electronic holiday detection (for thin-film systems) and/or flood testing (for rooftop and terrace systems). Flood testing involves ponding water on the completed waterproofed surface to a depth of 25–50 mm for a minimum of 24–48 hours to verify waterproof integrity before any overlay or finish coat is applied. Results are documented and a test certificate is issued.
Challenge: A 15,000 sq. ft. pharmaceutical manufacturing facility in Hyderabad was experiencing water ingress through the existing aged bituminous rooftop waterproofing, causing GMP deviations and contamination risk to the production area below.
Solution: Complete removal of the failed bituminous system, crack repair using CIPY repair mortars, application of CIPY PU membrane at 1.5 mm DFT with fibreglass reinforcement at details and a heat-reflective topcoat.
Result: Zero water ingress through three subsequent monsoon seasons. GMP compliance restored. Estimated 8°C reduction in roof surface temperature from heat-reflective topcoat, reducing HVAC load.
Challenge: A new-construction multi-level warehouse complex in Pune required positive-side basement waterproofing for 8,000 sq. ft. of below-grade walls and floor slabs, with groundwater at shallow depth creating hydrostatic pressure.
Solution: CIPY crystalline waterproofing system applied to the positive (external) face of the basement walls during construction, supplemented by CIPY cementitious waterproofing on the internal face of all below-grade concrete elements.
Result: Completely dry basement from first occupation. Crystalline system provides permanent self-sealing capability — if minor cracks develop due to structural settlement, the crystalline crystals re-grow to seal them.
Challenge: A food processing plant's 200,000-litre overhead RCC water storage tank was experiencing structural leakage and required waterproofing lining — with the critical requirement that the lining system be safe for potable water contact.
Solution: Full internal surface preparation by high-pressure washing and grinding. Application of CIPY potable water approved cementitious waterproofing system in three coats — including cove skirting at the tank base and sealed pipe penetrations.
Result: Fully watertight tank with potable-water-approved lining, compliant with food safety requirements. Water tank returned to service within 7 days of lining completion after full cure and flush cycle.

Learn More About CIPY SystemsIndustrial waterproofing is the application of specialist waterproofing membranes, coatings, and systems to industrial structures — rooftops, terraces, basements, underground areas, and water tanks — to prevent water ingress that could damage the structure, production equipment, products, or electrical systems. It differs from residential waterproofing in the performance requirements, scale, and durability standards applied.
Properly installed CIPY PU membrane systems on rooftops last 10–15 years. Crystalline waterproofing for below-grade concrete structures effectively lasts the lifetime of the structure. Acrylic coatings last 7–10 years on exposed surfaces. Sri Sai Technologies offers up to 10-year workmanship warranty on qualifying CIPY PU membrane installations.
For most Indian industrial factory rooftops, CIPY polyurethane (PU) membrane waterproofing is the preferred system. It provides high elongation to accommodate thermal movement in large-span roofs, excellent UV resistance, seamless application, and long service life. Heat-reflective topcoats are recommended to reduce solar heat gain and extend membrane life.
In most cases, failed waterproofing should be completely removed before a new system is applied. Applying new waterproofing over an existing failed system typically transfers the failure mode upward. However, where the existing system is sound but nearing end of life, overcoating with a compatible CIPY system may be appropriate. Sri Sai Technologies carries out a condition survey to determine the correct approach for each situation.
Crystalline waterproofing uses reactive chemicals that, when applied to concrete and exposed to water, react with calcium silicates in the concrete to form insoluble crystals that fill pores, capillaries, and micro-cracks. This makes the concrete itself permanently impermeable — unlike a membrane applied to the surface. The crystals re-activate whenever water contacts the concrete, making it self-sealing for the life of the structure.
Yes. Sri Sai Technologies provides workmanship warranty on all waterproofing projects. Qualifying CIPY PU membrane rooftop installations carry up to 10-year workmanship warranty. Pidilite Industries also provides material warranties for CIPY products. Full warranty terms, conditions, and maintenance requirements are specified in the project contract documentation.
Yes. CIPY offers waterproofing systems specifically approved for potable water contact — suitable for lining overhead RCC tanks, underground sumps, and other drinking water storage structures. These systems are tested to confirm they do not leach harmful substances into stored water. Sri Sai Technologies will confirm the appropriate potable-water-approved CIPY product for your specific application.
Rooftop and terrace waterproofing is typically verified by flood testing — ponding water at 25–50 mm depth across the completed waterproofed area for 24–48 hours before any overlay is applied. The underside of the slab is inspected for any evidence of water seepage during the test. Electronic holiday detection can also be used for thin-film membranes. Sri Sai Technologies documents all test results in a commissioning report.
