Waterproofing services in Pakistan
A roof treatment is only as dependable as its preparation and detailing
Rubber Tech Plus provides roof waterproofing services in Karachi and handles project enquiries across Pakistan. We assess the roof, correct agreed defects and apply a compatible system around exposed surfaces, junctions and penetrations.
Practical advantages
- Continuous liquid-applied coverage across prepared roof surfaces
- Detailed application around upstands, penetrations and complex junctions
- System selection matched to the substrate, exposure and project conditions
- Suitable for planned roof maintenance and waterproofing refurbishment
Liquid-applied protection
Liquid PU Membrane for continuous roof coverage
Applied in liquid form, the membrane follows prepared roof surfaces and detailed areas without relying on a single flat sheet. That makes careful preparation, compatible layers and controlled application essential to the finished system.
Continuous application
Coverage can follow corners, upstands and complex roof geometry.
Project-specific build
Primer, detailing and membrane layers are selected after the roof is assessed.
Visible site work
The supplied project photography shows the product and application in real conditions.
Condition-led advice
Existing coatings, moisture and drainage are reviewed before recommendations are made.
Roof waterproofing applications
Protection planned around each roof environment
Concrete roofs and terraces
Liquid-applied roof waterproofing for properly prepared concrete slabs, terraces and parapet details.
Industrial metal roofs
Waterproofing work for roof sheets, laps, fasteners, penetrations and other vulnerable details.
Solar-panel roof areas
Careful membrane application around supports and restricted-access areas beneath rooftop solar installations.
Plant and service roofs
Protection for industrial roof zones carrying equipment, services and regular maintenance access.
Existing roof refurbishment
Condition-led treatment for ageing waterproofed surfaces after defects and compatibility are reviewed.
Detailed roof junctions
Continuous treatment around drains, kerbs, corners, pipe entries and wall-to-floor junctions.
Application process
How roof waterproofing is applied
The sequence is adapted to the existing roof and the approved system. Weather and curing conditions are considered throughout the work.
- 01
Roof inspection
We review the substrate, existing treatment, cracks, joints, drainage, penetrations, moisture and access conditions.
- 02
Surface preparation
Loose material, dust and contamination are removed before defects and vulnerable details are treated as agreed.
- 03
Detailing and priming
Compatible preparation is completed around corners, upstands, outlets and penetrations before the main membrane application.
- 04
Liquid membrane application
The specified system is applied in controlled layers across the prepared surface, including critical roof details.
- 05
Inspection and curing
Coverage and detailing are checked, then the treated area is protected through the required cure period before handover.
System selection
Selected for the roof—not by product name alone
Substrate condition, existing treatment, water movement, detailing, exposure and access all influence the preparation and waterproofing system considered for a project.
Substrate and layers
Concrete, metal and existing coatings need compatible preparation and system layers.
Weather exposure
Rain, standing water risk and application conditions are reviewed during planning.
Drainage and details
Outlets, slopes, cracks, upstands and penetrations receive focused assessment.
Access and service
Roof traffic, rooftop equipment and maintenance needs inform the finished treatment.
Waterproofing FAQ
Planning your roof waterproofing project
Send the roof area, condition and photographs for a project-specific review.
What is liquid PU membrane waterproofing?+
A liquid PU membrane is applied over a prepared surface to form continuous waterproofing coverage. The suitable system and application method depend on the substrate, exposure and roof condition.
Can you waterproof an existing concrete roof?+
Existing concrete roofs can often be treated after their condition, cracks, moisture, drainage and previous coatings have been assessed and prepared appropriately.
Do you provide roof waterproofing services in Karachi?+
Rubber Tech Plus is based in Karachi and handles roof waterproofing enquiries for residential, commercial and industrial projects, with project enquiries welcomed from across Pakistan.
Can waterproofing be applied around solar panels?+
Yes, subject to safe access and a site assessment. Supports, penetrations, drainage paths and restricted areas require careful detailing during application.
How long does roof waterproofing take?+
Timing depends on roof area, preparation and repairs, access, weather, number of layers and curing requirements. A programme is confirmed after inspection.
What information is needed for a quotation?+
Share the roof location and area, substrate, current leakage or surface condition, previous treatment, access details and clear photographs of the roof and problem areas.
