Concrete Repair & Render Repair
Investigation and testing of concrete and rendered structures to ascertain the cause and extent of defects and validate repair specifications prior to the implementation of remedial works. Typically, this highlights problems such as concrete and render damaged by abrasion, impact, poor compaction and reinforcement corrosion.
We apply decorative and protective coverings of plaster, cement or similar materials to the interiors and exteriors of buildings.
Spray on Paving
Spray on paving is a low maintenance system with unlimited patterns and colours that can be used in driveways, pool areas, entranceways, terraces, interior floors, footpaths, carports and any other concrete surface. We provide products and services for the repair, restoration and decoration of existing concrete surfaces.
Waterproofing is the application of an impervious barrier to surfaces to stop water penetrating from localised areas into other parts of the building where damage can occur. These are either internal (toilets, bathrooms, en-suites, laundries etc) or external areas (planters, podiums, retaining walls etc). In addition they can be flat concrete.
Grout Injection (crack injection)
In remedial situations, structural leak sealing can be achieved by means of injected hydroactive resin based grout materials. Using specially developed equipment, appropriate materials are injected in cracks, joints or other defects in structures such as water containment and treatment structures, tank storage bunds, tunnels, pump wells, swimming pools, lift pits, basements, manholes and culverts etc where water ingress or egress is evident.
Hydroactive resins react expansively when in contact with water in a crack or joint to form a foam or gel seal, hence rapidly reducing and stopping water penetration. Variations in resin formulation allow injected resin to react rapidly to deal with situations where water flow is high, or remain flexible where ongoing movement is anticipated. Resins have also been formulated to enable water penetration through the finest cracks in concrete structures to be effectively sealed.
Other areas of expertise are available to deal with other forms of leakage, such as, through joints in large diameter pipes and precast tunnel structures. Other applications include waterproofing to resist negative pressures (such as in basements), waterproofing expansion joints subject to high levels of movement (such as in sectional water storage tanks, on podium roofs and car parks and bridge structures).
We are able to rectify leaks in concrete structures with very little disruption to the facility or site without costly downtime being experienced and the requirement for expensive excavations.
Underwater Crack Inspections & Injection and Underwater Concrete Repairs
Services extend to inspections, reports, crack injection and repairs of swimming pools and tanks.
Our services for underwater concrete repairs and cracks do not require the removal of any water, as products we use can be applied underwater. Given there is no water wastage, this is environmentally friendly and a cost effective service for our clients.
Joint sealants are used to seal joints and openings between two or more substrates. The main purpose is to prevent air, water, and other environmental elements from entering or exiting a structure while permitting limited movement of the substrates.
