Commercial and industrial buildings in Pakistan carry far more risk from water than an ordinary home. A single leak over a textile warehouse in Faisalabad can ruin rolls of fabric; water dripping onto a production line in Sundar or Quaid-e-Azam Industrial Estate can stop machines and create electrical hazards; a seeping basement under a Lahore plaza can damage parked cars and tenant stores; and a leaking roof in a hospital or school disrupts services that cannot simply close. These buildings also have larger and more complex roofs: wide RCC slabs with many drains, metal sheet roofs with hundreds of fasteners and overlaps, rooftop HVAC units, solar arrays, water tanks and service penetrations. Wellcool provides professional commercial and industrial waterproofing for factories, warehouses, cold stores, shopping plazas, office buildings, hotels, hospitals, schools, universities, mosques and apartment complexes across Lahore, Islamabad, Rawalpindi, Faisalabad, Gujranwala, Sialkot, Multan, Peshawar and the industrial zones of Punjab and KPK.
We work the way facility managers and owners need: a detailed survey, a written specification with clearly defined systems and areas, a phased work programme that avoids shutting down operations, attention to safety on large roofs and sites, and documentation at every stage. Our systems cover concrete roofs, metal sheet roofs, basements, parking decks, water tanks, wet areas and expansion joints, selected to handle heavy use, extreme heat and monsoon rainfall.
Size and complexity are the first challenge. Large roofs have long drainage runs, many outlets, expansion joints and equipment, and a single neglected detail can cause a leak far from where it appears inside. Heavy use is the second: maintenance staff, technicians and equipment move across roofs regularly, and parking decks and loading areas carry vehicle traffic. Equipment and penetrations such as HVAC units, chillers, exhaust ducts, solar arrays and pipe racks create dozens of openings that must each be sealed.
Metal sheet roofs on factories and warehouses bring their own problems: rusted fasteners, open side and end laps, failed ridge caps, damaged skylight sheets and gutters that overflow during monsoon bursts. Operational constraints mean work must often be carried out without stopping production, closing shops or disturbing patients and students. And heat remains a major factor; industrial roofs in Punjab reach extreme temperatures that degrade ordinary materials quickly and make working conditions inside very hot.
Facility managers should act when they see:
Roof-by-roof mapping of defects, drains, joints and equipment.
Phased work, off-hours scheduling and protection of stock and equipment.
Safe access, edge protection awareness and tidy material handling.
Written specifications, progress updates and handover reports.
For RCC roofs on plazas, offices, hospitals and schools, we repair cracks and screeds, correct ponding, rebuild drain outlets and apply liquid polyurethane or acrylic membranes reinforced at all details, or torch-applied modified bitumen membranes where suited. Heat-reflective top coats reduce roof temperature and cooling loads.
On factory and warehouse sheds, we replace or seal rusted fasteners, seal side and end laps with butyl tape and sealant, repair or replace damaged sheets and skylights, seal ridge caps and flashings, and apply elastomeric or reflective coatings over the sheets. Gutters and valleys are cleaned, repaired and lined to handle heavy monsoon flows.
Seepage in basements is treated with crystalline coatings, PU or acrylic injection of leaking cracks and joints, and cementitious systems on walls and floors. Parking decks receive traffic-grade PU or epoxy deck coatings with anti-skid finishes.
Expansion joints between building blocks are a frequent leak source. We remove failed fillers and install flexible joint sealants or joint membranes designed to move with the structure while staying watertight.
Overhead and underground water tanks, fire tanks, washrooms, kitchens, canteens and process wash-down areas are waterproofed with cementitious, epoxy or PU systems suited to the use, including potable-water-safe linings where required.
Many clients combine waterproofing with heat reduction. Reflective coatings on concrete and metal roofs lower inside temperatures, improving working conditions and reducing cooling costs. See industrial shed heatproofing and factory roof heat insulation.

Industrial clients in textiles, food processing, pharmaceuticals, packaging, sports goods and surgical instruments rely on dry facilities to protect raw materials and finished goods. For these sites we focus on roof watertightness above production and storage zones, gutter and valley capacity for monsoon downpours, and sealing around exhaust fans, skylights and machinery penetrations. Work above sensitive areas can be scheduled during shutdowns, weekends or night shifts, with sheeting used to protect stock and machines below.
In commercial plazas and office buildings, leaks disturb tenants and damage false ceilings, lighting and IT equipment. Basements and parking levels suffer seepage, and rooftop terraces, water tanks and HVAC platforms need attention. We coordinate with building management to schedule work with minimal disturbance, keep common areas clean and safe, and address roof, basement, parking and wet-area waterproofing in a single programme.
Hospitals, clinics, schools, colleges and mosques cannot simply close for repairs. Leaks in wards, operation theatres, classrooms and prayer halls create health and safety concerns. We plan work during holidays, off-peak hours or in small phases, use low-odour water-based systems where possible in occupied buildings, and keep work areas separated from users. Large roofs on these buildings also benefit greatly from heat-reflective coatings.
Large roofs and industrial sites carry real risks: fragile skylight sheets, unprotected edges, live equipment and heavy materials. Our teams follow safe working practices, use proper access, avoid walking on fragile sheets, keep materials organised and keep drains clear of debris. Quality is controlled through surface checks, coverage measurement, detail inspections and water testing where practical, with progress shared with the client’s site representative.
For industrial facilities, the pre-monsoon period is critical. Gutters and valleys on large sheds must carry enormous volumes of water within minutes during a cloudburst; if they are blocked or undersized, water overflows into the building. We recommend a pre-monsoon survey and maintenance programme each year that covers gutter cleaning, fastener and lap checks, drain clearing and coating touch-ups, so your facility is ready before the rains.
Commercial clients often combine waterproofing with commercial building heatproofing, industrial shed heatproofing, protective coating application, basement waterproofing, roof maintenance services and commercial office wall art for interiors.
Cold stores, dairies, meat and poultry plants, bakeries and food processing units face constant moisture from wash-down, condensation and temperature differences. Water leaking into insulated panels destroys their performance, and damp floors and walls breed bacteria. For these facilities we focus on watertight roofs above insulated areas, seamless and hygienic floor and wall coatings in wet zones, properly sealed floor drains and joints that resist hot water, cleaning chemicals and frequent washing. Work is planned with the client’s hygiene and production schedules in mind.
Commercial roofs increasingly carry chillers, cooling towers, ducts, generators, telecom equipment and large solar installations. Every base, stand and cable tray is a potential leak point, and equipment often blocks access for later repairs. We seal plinths and penetrations with collars and reinforced membrane, raise or protect cable routes, and keep drainage paths around equipment clear. Where a new solar array is planned, we strongly recommend waterproofing the roof beforehand, since repairing under thousands of panels later is costly and slow.
Many factories in Punjab operate in buildings decades old, with roofs that have received countless patch repairs. Our survey identifies whether targeted repairs will extend the roof’s life for a few seasons or whether a full renewal is more economical over time. For metal roofs, this may mean comparing sealing and coating against sheet replacement; for concrete roofs, overcoating against stripping and renewing. We give owners a clear comparison so they can plan capital spending sensibly. See old waterproofing removal & renewal.
For facility managers responsible for several buildings or large sites, a planned maintenance arrangement keeps roofs and waterproofing in good order and avoids emergency call-outs during the monsoon. Scheduled visits can cover roof and gutter inspections, drain clearing, fastener and lap checks on sheds, sealant and coating touch-ups, basement seepage checks and written condition reports. This turns unpredictable leak repairs into planned, budgeted work.
On new commercial projects and major renovations, we can work alongside main contractors, consultants and architects, following their specifications or proposing waterproofing details for roofs, basements, podiums, wet areas and water tanks. Early involvement allows waterproofing to be planned with drainage, slopes and services, avoiding conflicts and leaks later.
Loading bays, dock canopies and covered walkways are often built as add-ons to the main structure, with weak joints where they meet the building. Rainwater leaks through these junctions onto goods being loaded, and canopy gutters overflow in monsoon bursts. We seal canopy-to-wall junctions with flashings and flexible membranes, upgrade gutters and downpipes, and waterproof the canopy surface so goods and staff stay dry.
