Services We Offer
Inspection-led waterproofing services for roofs, structures, water tanks, bathrooms and basements across Karachi.
WHAT WE DO
Being in service to others is what brings true protection.
Pak Chemical Services provides professional waterproofing services in Karachi for residential, commercial and industrial properties.
Our work begins with a site inspection. We assess visible cracks, joints, drainage points, dampness and routes of water entry before recommending a suitable repair or waterproofing system.

Our Waterproofing Services in Karachi
Pak Chemical Services provides specialized waterproofing solutions for roof surfaces, structures, water tanks, bathrooms and basements.
Roof Waterproofing Services
Roof waterproofing helps protect exposed roofs against rainwater, moisture penetration and progressive surface deterioration.
We work on: RCC roofs, concrete roofs, flat roofs, terrace roofs, factory roofs, warehouse roofs, commercial rooftops and residential rooftops.
Before recommending a system, we assess the roof surface, drainage, visible cracks, joints, ponding areas and any previous treatment. The approved scope may include cleaning, removal of weak material, crack treatment, primer application and installation of a suitable waterproofing system.
Roof Leakage Repair
A damp ceiling may not be directly below the point where water enters the roof. Rainwater can travel through cracks, joints, pipe penetrations and damaged concrete before appearing inside.
Treatment may include: crack filling, joint sealing, damaged concrete repair, drainage-point treatment, surface preparation, local waterproofing and protective coating application.
Structural movement, physical damage, later construction work or untreated roof sections can create new leakage problems.
Basement Waterproofing
Basement seepage may result from groundwater pressure, concrete cracks, construction joints, poor drainage or moisture moving through walls and floors.
Ignoring these problems can damage interior finishes, stored materials, electrical systems, equipment, concrete surfaces and indoor air quality.
We serve industrial buildings, warehouses, parking areas, commercial properties, apartment buildings, villas and houses. The recommended solution depends on active water entry, recurring dampness, deteriorated surfaces and construction requirements.
Water Tank Waterproofing
Concrete water tanks may develop leakage through cracks, joints, damaged plaster, deteriorated concrete or failed previous coatings.
Our process may include: draining and cleaning the tank, removing weak material, repairing cracks and joints, preparing concrete, applying an appropriate system and conducting a final inspection.
The selected product must be suitable for the tank’s intended use, concrete condition and technical requirements.
Roof Protection Coatings
Roof protection coatings create an additional barrier on exposed concrete surfaces. Correctly prepared systems may help reduce direct exposure to rainfall, moisture, sunlight, surface weathering and environmental deterioration.
The selected system may include primer, acrylic coating, polyurethane coating, joint sealant or compatible repair materials. Loose coatings, damaged concrete, open joints and visible cracks should be treated first.
Gray Structure Waterproofing
Waterproofing during the gray-structure stage allows leakage-prone areas to be treated before tiles, plaster, paint and other finishes are installed.
The approved scope may include roof slabs, basements, concrete water tanks, construction joints, structural penetrations and other moisture-sensitive concrete surfaces.
The final recommendation depends on drawings, construction stage, substrate condition and intended use.
Industrial, Commercial and Residential Waterproofing
Our waterproofing services in Karachi are available for different property types and operational requirements.
Industrial Waterproofing
Factories, warehouses, plants, textile units, pharmaceutical facilities, food-processing plants and logistics buildings often have large roof areas and complicated access requirements.
Projects may involve ponding water, expansion joints, service penetrations, aging concrete, failed coatings, restricted hours and operational safety requirements.
Commercial Waterproofing
We serve office buildings, retail properties, shopping centres, hospitals, hotels, schools, colleges, universities and managed commercial buildings.
Where necessary, work may be completed in controlled stages with preparation, application areas and access clearly defined.
Residential Waterproofing
Homeowners contact us for leaking rooftops, damp ceilings, concrete cracks, terrace seepage, basement dampness, water-tank leakage and failed old roof coatings.
We serve houses, villas, apartment buildings and shared residential structures throughout Karachi.
Common Waterproofing Problems We Inspect
- Water entering after rainfall
- Damp ceilings and walls
- Peeling paint
- Open roof cracks
- Damaged construction joints
- Ponding water
- Concrete deterioration
- Basement seepage
- Water-tank leakage
- Failed previous coatings
- Moisture in new construction
- Leakage around service penetrations
Correct diagnosis matters because similar internal stains can have different causes. Roof leakage, plumbing leakage, condensation, water-tank seepage and wall dampness should not automatically receive the same treatment. A proper assessment helps prevent money being spent on the wrong service.
Our Inspection and Application Process
Pak Chemical Services uses a structured process for its waterproofing services in Karachi.
01. Site Inspection
We inspect the affected roof, basement, tank or structural surface and review visible signs of leakage, dampness and deterioration.
02. Problem and Surface Assessment
We examine cracks, joints, drainage, ponding, loose concrete, deterioration and likely routes of water entry.
03. Recommended Scope and Quotation
The service, treatment area, preparation, materials and applicable warranty option are described before approval.
04. Surface Preparation
Dust, debris, contaminants, loose concrete and weak previous coatings are removed where required.
05. Crack, Joint and Damage Repair
Relevant cracks, joints and visibly damaged areas are treated before the main waterproofing system.
06. Waterproofing System Application
The approved primer, coating, sealant, cementitious system or repair material is applied according to scope.
07. Final Inspection and Handover
The treated area is checked for visible coverage and workmanship issues before project handover.

Frequently Asked Questions
Which waterproofing service do I need?
The correct service depends on the source and location of the problem. Roof leaks, basement seepage, water-tank leakage and new-construction waterproofing require different materials and treatment methods. A site inspection helps identify the most suitable service.
Do you inspect the property before providing a quotation?
Yes. An inspection allows the team to assess the affected area, surface condition, visible cracks, drainage and previous treatment before preparing a recommended scope and quotation.
Can failed or old waterproofing be repaired?
In many cases, yes. Failed coatings, cracks, joints and damaged concrete may be repaired after inspection and proper surface preparation. Complete removal or a different system may be required where the previous treatment is unstable.
Do you work on factories and warehouses?
Yes. We provide industrial waterproofing services in Karachi for factories, warehouses, textile units, manufacturing buildings and other suitable facilities. Scheduling and system selection depend on roof condition, access and operational requirements.
Do you waterproof basements and concrete water tanks?
Yes. Pak Chemical Services provides basement and concrete water-tank waterproofing for suitable industrial, commercial and residential properties. Both structures require separate inspection and treatment planning.
How is waterproofing cost calculated?
Cost depends on total treatment area, surface condition, crack and concrete repairs, selected system, number of coats, access requirements, existing failed treatment and warranty scope. A fixed rate without inspection may not reflect the actual work required.
Which areas of Karachi do you cover?
We serve major industrial, commercial and residential locations, including SITE, Bin Qasim, Korangi, Landhi, Port Qasim, DHA, Clifton, Gulshan-e-Iqbal, PECHS, Nazimabad and nearby areas.
