Project solutions
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.
Solutions in build order
What this project needs, step by step
Waterproof (watertight) concrete
For basements, water tanks, pools and sewage works, make the concrete itself resist water with a low water–cement ratio, an integral waterproofing admixture and sealed construction joints. This is for new pours; it cannot fix a structure that already leaks.
Basement waterproofing from outside (positive side)
For new basements, or where the soil can be dug away, stop water on the face that the soil and groundwater press against. Build watertight concrete, seal every joint, coat or sheet the outside face, then backfill carefully.
Car-park decks & ramps
Car-park decks face tyre wear, oil, water and, on the open top deck, sun and monsoon rain. A crack-bridging resin system with a UV-resistant seal coat and sealed joints protects the slab and the floors below.
Floor joints in car parks, warehouses and roads
Saw-cut, expansion and connection joints in floors that carry people, cars, forklifts or trucks. The sealant must take both traffic and movement, and the joint must be sized for it.
Building expansion and movement joints
The gaps between building blocks, slabs, walls and roofs that let the structure expand, shrink and settle. They need a sealant or tape matched to the movement, a correctly sized joint and a backer rod, or water gets in and edges break.
Spalling concrete (chhajja, balcony, beam, column)
Concrete that cracks, bulges and falls away, usually with rusty steel behind it, on chhajjas, balcony slabs, beams, columns and tank slabs. This guide follows the EN 1504 sequence: remove, protect the steel, rebuild, seal and protect.
Rusting reinforcement (rebar corrosion)
Steel bars inside concrete rust when carbonation or chlorides reach them; the rust swells and cracks the cover. This guide covers finding corrosion early, treating exposed steel, and slowing corrosion in concrete that has not spalled yet.
Protective coatings & water repellents for concrete
Coatings and impregnations that keep water, chlorides and carbon dioxide out of concrete facades, bridges, car parks and repaired structures. Choose a clear impregnation, an anti-carbonation coating or a crack-bridging coating to suit the exposure.
Chemical anchors, rebar & dowels
Chemical anchors fix bolts, threaded rods and new reinforcement bars into existing concrete or masonry for extensions, railings, machines and services. Load capacity depends on the design, hole cleaning and base material, so safety-critical work needs an engineer.
