Creating waterproofing solutions for all your problems!

Water damage rarely announces itself. It creeps in through hairline cracks, poor slopes, and aging joints until it becomes a serious problem — one that's far more expensive to fix than to prevent. At Dev Enterprises, we treat waterproofing as an engineering problem, not a cosmetic one. That means we start by identifying the actual source of leakage or seepage, then apply a system matched to your structure's material, exposure, and usage — not a one-size-fits-all coating.

Signs You May Need Waterproofing
  •  Damp patches or discoloration on ceilings and walls

  •  Peeling paint or plaster, especially after monsoon

  • A musty smell in basements or enclosed areas

  • Visible seepage near windows, joints, or the terrace edge

  • White, powdery deposits (efflorescence) on walls

  • Water stains or dampness in parking and basement levels

  • Cracks on the terrace surface or external walls

Our Services

Terrace & Roof Waterproofing Terraces take the brunt of sun, rain, and temperature swings, which makes them one of the most common sources of leakage. We assess slope, ponding areas, and existing cracks before applying a membrane or coating system designed to handle years of direct weather exposure.


Bathroom & Wet Area Waterproofing Bathrooms, kitchens, and utility areas see constant water contact in a relatively small, joint-heavy space — exactly why they're the most common source of internal leakage complaints. We waterproof floors, walls up to the required height, and critical junctions like drain outlets and pipe penetrations.

Basement & Podium Waterproofing Below-ground and podium structures face constant water pressure from surrounding soil, which surface coatings alone can't handle. We use membrane systems and, where needed, injection-based methods designed specifically for below-grade conditions.


Water Tank Waterproofing Overhead and underground water tanks need treatment that's both watertight and safe for potable water. We use tested, non-toxic systems suited to drinking water storage, along with treatments for tanks used in non-potable applications.


External Wall & Facade Waterproofing Exterior walls face constant rain infiltration and, over time, develop dampness and efflorescence that affects both structure and appearance. We apply breathable coatings that keep water out while still letting trapped moisture escape.


Expansion Joint Treatment Expansion joints allow a structure to move without cracking, but they're also a common entry point for water if not sealed correctly. We install joint sealants and detailing designed to flex with the structure while maintaining a watertight seal.


Balcony & Sunken Slab Waterproofing Balconies and sunken slabs (under bathrooms and kitchens) are particularly leak-prone due to pipe penetrations and constant water exposure. We waterproof these areas with close attention to detailing around drains, pipes, and slab edges.

Swimming Pool Waterproofing Pool structures face constant water contact plus the structural movement of a large concrete vessel — a combination that calls for a purpose-built system rather than a standard membrane.


Lift Pit / Elevator Pit Waterproofing Lift pits sit below ground level and are especially vulnerable to water ingress, which can damage elevator machinery. We treat these confined, critical spaces with waterproofing systems built for constant below-grade exposure.


Injection Grouting for Active Leakage When a leak is already active, we don't always need to break open the surface. Injection grouting seals cracks and voids from within the structure, often avoiding major demolition and reducing both cost and disruption.

Industrial & Large-Format Roofing Warehouses, factories, and industrial sheds need waterproofing systems scaled for large surface areas and heavy-duty exposure, including foot traffic, equipment movement, and prolonged weathering.

Materials & Techniques We Use

Do you need help?

We select from a range of proven systems based on your surface, exposure, and budget:

  • Cementitious coatings — reliable, cost-effective protection for standard wet areas

  • Liquid-applied membranes — flexible, seamless coverage ideal for terraces and roofs

  • Crystalline waterproofing compounds — penetrate into the concrete itself for long-term, internal protection

  • Polyurethane (PU) membranes — durable and weather-resistant, suited to high-exposure areas

  • Injection grouts — for sealing active leaks and cracks without major demolition

Our Process

1. Site inspection & leak diagnosis — identifying the actual root cause, not just the visible symptom


2. Customized solution design — recommending a system suited to your specific surface, exposure, and usage


3. Surface preparation — cleaning, repairing, and priming the surface, since proper prep determines how long the job lasts


4. Application by trained teams — skilled application with correct layer thickness and curing time at every stage


5. Testing & handover — leak-tested (typically with a water ponding test) before the job is considered complete


6. Warranty & maintenance guidance — a clear warranty scope, plus simple guidance on maintaining the treated area
