Two-storey flat-roofed house in the rain, with the roof waterproofing turned up the parapets highlighted in orange House / villa Pakistani homes leak mostly at the roof, bathrooms, water tanks and external walls. Waterproofing done in the right order during construction avoids breaking finished tiles later. 14 solutions Apartment block cut open to show stacked bathrooms, each with an orange waterproofing layer on the floor and up the walls Apartment building Mid-rise apartment blocks share one basement, one roof and one set of tanks, so a single leak affects many families. Wet areas stacked above each other make good under-tile waterproofing essential. 13 solutions Tall glass tower in wind-driven rain, with the sealed joints between its facade panels highlighted in orange High-rise tower Towers need concrete that can be pumped high in summer heat, deep basements below the water table, and a facade that seals against wind-driven rain. Fire-rated joints and penetrations matter in every shaft and floor. 14 solutions Hospital building with a ward cut open, showing a seamless orange floor coating that curves up the walls Hospital / clinic Hospitals need hygienic, easy-to-clean wet areas, floors and walls, and joints that do not hold dirt. Water tanks, fire-rated penetrations and a dry roof keep the building in service. 12 solutions Two-storey school with a verandah and playground swing in the rain, with its flat roof waterproofing shown in orange School / university Schools and campuses have large flat roofs, busy washrooms and long corridors that see heavy use. Roof leaks and cracked plaster before the monsoon are the most common repair calls. 12 solutions Hotel and restaurant beside a swimming pool cut in section, with the pool's waterproof lining highlighted in orange Hotel / restaurant Hotels and restaurants combine guest bathrooms, commercial kitchens, pools and stone finishes in one building. Water must stay where it belongs, and finishes must still look good after daily cleaning. 13 solutions Shopping mall with a tall arched glass atrium, with the sealed joint around the glazing highlighted in orange Shopping mall / retail Malls have basements and car parks below, large tiled or seamless floors in the middle, and a glazed facade outside. Food courts and washrooms add wet areas with heavy daily use. 13 solutions Glass office building with a basement below the water table, wrapped outside in orange waterproofing Office building Office buildings need a dry basement for parking and plant rooms, reliable washrooms on every floor, and a sealed facade. Fire-rated joints and penetrations run through every service riser. 12 solutions Mosque with a central dome and two minarets, with the waterproof coating over the dome highlighted in orange Mosque / community hall Mosques and community halls have wide roofs, domes and large ablution (wuzu) areas that are wet all day. Marble floors and walls need the right adhesive and grout to stay fixed. 11 solutions Factory shed cut open to show a machine on a concrete plinth, with the grout layer under its base plate in orange Factory / manufacturing plant Factories need floors that take forklifts, machines that sit level on their bases, and protection where chemicals are used. Downtime is expensive, so cure times matter as much as the products. 12 solutions Warehouse cut in section with pallet racks, with the floor slab surface and its joints highlighted in orange Warehouse / logistics Warehouses live or die by their floor slab: dusting, worn joints and broken edges slow every forklift. Racking anchors, crane rails and a dry roof complete the job. 9 solutions Food plant cut in section with steel vessels, the floor sloping to a drain under an orange seamless coating Food / pharma plant Food and pharmaceutical plants need hygienic floors and walls that take hot water, cleaning chemicals and constant washing. Joints and grout lines must not trap dirt. 11 solutions Power plant cooling tower and transformer yard, with the water basin under the tower lined in orange Power plant / grid substation Power plants and substations rest on heavy foundations, with turbines, transformers and switchgear that must sit exactly on their bases. Cable trenches, oil bunds and fire separation need sealing. 11 solutions Two round water treatment tanks with bridges, with the lining inside the larger tank highlighted in orange Water treatment plant Treatment plants are full of water-retaining concrete: clarifiers, filters and clear-water reservoirs. Any part that holds drinking water needs linings and sealants whose data sheet allows drinking-water contact. 9 solutions Sewage plant aeration tank cut in section with bubbles, its inner walls lined in orange, beside a round clarifier Sewage treatment plant Sewage plants hold water that attacks concrete and corrodes steel. Watertight concrete, chemical-resistant linings and sound joints keep the structure in service. 9 solutions Flyover deck on two concrete piers, with the bearings between the deck and the pier tops highlighted in orange Bridge / flyover Bridges and flyovers need strong concrete placed in heat, bearings grouted level, and expansion joints that move. Older bridges need repair, corrosion protection and sometimes strengthening to an engineer's design. 10 solutions Road tunnel entrance in a wet hillside, with the waterproof membrane around the tunnel arch shown in orange Tunnel / underpass Tunnels and underpasses sit in wet ground, so water through joints and cracks is the main problem. Sprayed concrete, sheet membranes and injection are the usual tools. 8 solutions Concrete runway or highway in perspective with a plane overhead, the joints across the pavement shown in orange Road / highway / airport Concrete pavements, runways and aprons need durable, workable concrete, good curing in the heat and sealed joints. Dowels, signs and barriers need reliable anchoring. 7 solutions Concrete dam in section holding back a reservoir, the water-side face shown in orange, with a canal downstream Dam / canal / irrigation Dams, barrages and canals mean large pours, constant water and wide joints. Watertight concrete, controlled setting and sealed joints come first; repair and protection follow over the years. 9 solutions Multi-storey car park with ramps and open decks, with the coating on the exposed top deck highlighted in orange Parking structure Car parks face tyre wear, oil, water and moving joints, and the steel in their slabs is at risk of rust. A deck coating, sound joints and early repairs keep the structure working. 9 solutions Port quay with a container crane over a ship, the quay wall's splash zone at the waterline shown in orange Marine / port Port structures on the Karachi and Gwadar coast face seawater, salt spray and heavy loads. Durable concrete, corrosion protection and grouted crane rails are the core of the work. 9 solutions Fuel storage tanks inside a low containment wall, with the bund lining and floor joints highlighted in orange Industrial tank farm / fuel depot Tank farms and fuel depots need tank foundations, anchored equipment and bunds that hold spills. Joints in fuel areas need a sealant made for water-polluting liquids. 8 solutions
