Mainmark has delivered ground engineering solutions to businesses for more than 25 years. Capitalising on this expertise, our latest range of innovative products and advanced solutions provide remediation of assets and structures across commercial, civil, infrastructure and mining sectors.

Our methods provide ideal solutions for numerous applications, such as: level correction of sinking floors and buildingsstrengthening weak and unstable groundfilling holes, voids and pipesearthquake remediation; and in-ground water and gas control. Mainmark offers advanced, site-specific solutions for revitalising, sealing, protecting and structurally reinforcing ageing or damaged buildings and infrastructure including tunnels, shafts and basements impacted by weak ground and water ingress. Mainmark’s industrial strengthening solutions provide concrete and steel coatings for building and infrastructure protection, precisely designed and engineered for site-specific needs.

The solutions we provide are non-invasive, cost and time efficient and suitable for any business, from Commercial and Industrial sectors,  Government and Councils through to Infrastructure and Mining and Resources. Mainmark’s methods are successful on any size structure, of any type, including Heritage buildings.

Slab Lifting, Slab Jacking and Slab Re-levelling

Mainmark provides bespoke solutions for slab lifting and re-levelling addressing the underlying problem of subsidence by strengthening the ground beneath. Our level correction methods can cater to any building size, from homes and driveways to warehouses and transport yards, and are non-invasive, cost-effective, time-efficient, with minimal disruption to the occupants.

Slab lifting/jacking is the preferred way to bring sunken slabs back to level by injecting Teretek® (polyurethane resin) through a process likened to keyhole surgery. Injected through very small tubes (ranging from 6mm to 16mm) into the ground beneath the footings, the components mix together and expand by chemical reaction, which strengthens the ground and re-levels buildings quickly and with minimal disruption.

More Information

We use non-invasive techniques, likened to keyhole-surgery, so we don’t tear up floors and excavate ground (injection holes can be as small as 6mm).

We are very quick, completing small and large scale projects in a fraction of the time traditional methods would take.

We don’t cause disruption, so there is little, if any, downtime – in many cases, businesses can continue to operate throughout the process.

We strengthen the future of a structure, strengthening weak ground so buildings generally become level, crack-free, and more stable.

We don’t make mess because there is generally no dust, water, or anything else to clean up.

We don’t cause further damage, we fix existing damage. Wall cracks generally close up, doors and windows can usually operate properly again, and trip hazards are eliminated.
