Sunken slab waterproofing in Hyderabad is the process of treating the recessed concrete slab beneath bathroom and toilet floors — filled with brick bat coba or lightweight fill — using crystalline waterproofing compounds, polyurethane injection grouting, and multi-layer membrane systems to prevent water seepage through the slab into the ceiling of the floor below.
GK Waterproofing delivers expert exterior waterproofing services in Hyderabad for external walls, facades, parapets & basements. Elastomeric coatings, silane-siloxane impregnants & crystalline systems. 30+ years experience. Free inspection – +91 9849522248!
A sunken slab (also called a sunken floor or recessed slab) is a structural feature of Indian reinforced concrete construction where the bathroom, toilet, or kitchen floor slab is cast 300–450mm below the main floor level. This depressed area is filled with brick bat coba (broken brick and lime mortar), lightweight concrete, or infill material to bring it level with the rest of the floor. The void created within this sunken area is extremely vulnerable to water accumulation, stagnation, and slab penetration — because drainage pipes pass through the slab and the infill material acts like a sponge. Sunken slab waterproofing is the specialized treatment of this sub-floor void, slab surface, and drainage interfaces to create a completely impermeable barrier that prevents water from seeping through the RCC slab into the ceiling and walls of the apartment below.
Hyderabad's rapid urbanisation, aggressive monsoon weather, and challenging geological conditions create unique demands on building structures. Problems such as leakage, seepage, cracking, structural deterioration, and material failure are all accelerated by the local environment. GK's deep understanding of these local conditions allows us to design and execute Exterior Waterproofing strategies that are specifically calibrated for Hyderabad, rather than generic solutions that may perform poorly in the local context.
In Hyderabad's apartment buildings — particularly those built between 1990 and 2015 — sunken slab waterproofing was either skipped entirely or executed with substandard brick bat coba and bituminous paint that degrades within 3–5 years. The result is an epidemic of ceiling leakages in lower-floor apartments caused by upper-floor bathroom slab seepage. This is the single most contested issue between landlords and tenants, and between adjacent flat owners in multi-storey residential complexes. Proper sunken slab waterproofing requires specialized knowledge, the right materials, and complete excavation and re-treatment of the infill — which GK Waterproofing has been performing with 30+ years of expertise across thousands of Hyderabad properties.
Is water dripping from your neighbor's ceiling every time you shower? Has your building's management committee demanded you fix your bathroom's sunken slab leakage? Are you a landlord losing rental income because of persistent bathroom ceiling stains in the flat below? GK Waterproofing's certified sunken slab specialists will fully break out, treat, and rebuild your bathroom's waterproofing layer using the latest crystalline and membrane technologies — with a warranty of up to 7 years. This is the only permanent solution; surface treatments will fail. Trust 30+ years of experience and thousands of repaired sunken slabs across Hyderabad.

GK Waterproofing is Hyderabad's leading specialist in sunken slab waterproofing in bathrooms and wet areas — trusted by homeowners, builders, and businesses across Telangana for over 30 years. Sunken slab waterproofing during construction costs a fraction of the repair needed when seepage develops — GK provides both new construction and remedial sunken slab waterproofing. GK's certified professionals apply the most advanced sunken slab waterproofing in bathrooms and wet areas techniques available, delivering permanent solutions backed by a comprehensive service warranty.
Sunken slab waterproofing in bathrooms and wet areas in Hyderabad requires deep expertise in local building types, climate conditions, and structural characteristics. GK Waterproofing uses liquid waterproofing membrane, crystalline slurry, and polymer-modified mortar for sunken slabs — systems selected specifically for the demands of Hyderabad's monsoon-heavy climate, high humidity, and thermal cycling. Every project begins with a detailed site assessment to identify the root cause of the problem before treatment begins, ensuring the most appropriate and cost-effective solution is applied.
GK's approach to sunken slab waterproofing in bathrooms and wet areas is systematic and quality-driven: comprehensive site survey, detailed problem diagnosis, surface and structural preparation, professional system application by certified technicians, quality inspection at each stage, and full post-project warranty documentation. The common problem: sunken slabs in Hyderabad bathrooms and kitchens retain water and expose concrete to constant moisture — failing waterproofing causes seepage to the floor below — which is why professional GK intervention is essential. Our solution: GK waterproofs sunken slabs using liquid-applied membranes or crystalline coatings applied before or after tile laying, providing lasting protection against sunken slab seepage. GK serves residential apartments, villas, commercial buildings, industrial facilities, and civil structures across Hyderabad, Secunderabad, and the broader Telangana region.

A: A sunken slab is a bathroom or toilet floor that is cast 300–450mm below the main floor level during RCC construction, filled with brick bat coba, and finished with tiles. This design allows drainage pipes to run within the slab depth.
A: This is classic sunken slab waterproofing failure — water accumulates in the brick bat coba fill, saturates the RCC slab, and seeps through to the ceiling of the apartment below. Professional sunken slab treatment is the only solution.
A: In most cases, yes. Effective sunken slab waterproofing requires removing tiles, excavating the infill material, treating the bare slab, and rebuilding. Surface-only treatments cannot reach the slab.
A: Cost typically ranges from ₹150 to ₹350 per square foot inclusive of excavation, treatment, refill, and tiling, depending on the area and materials selected. GK Waterproofing provides free detailed quotations.
A: With GK Waterproofing's crystalline + membrane system, sunken slab waterproofing is designed to last the structural life of the building — 20+ years. We provide written warranties of 5–10 years.
A: Brick bat coba is the traditional Indian method of filling sunken slabs with broken brick and lime mortar. Over time, it absorbs and retains water, cracks under thermal cycling, and allows water to stagnate against the slab — making modern replacement with lightweight concrete and proper waterproofing essential.
A: Yes. All work is carried out from above — within the bathroom being treated — with no access required to the flat below.
A: A standard bathroom sunken slab project takes 3–5 days: one day for breaking, one for cleaning and treatments, one for membrane and fill, and one to two for tiling and grouting.
Crystalline waterproofing (Penetron or Kryton Krystol) combined with an APP bituminous membrane or polymer screed provides the most durable, permanent solution for sunken slab conditions.
A: Yes. GK Waterproofing provides written warranties of 5–10 years for sunken slab waterproofing projects, with free service call within the warranty period.
