Mainmark has delivered successful results to many Heritage buildings.

Mainmark has delivered successful results for many building owners, including those identified as heritage-listed, or located in World Heritage significant sites. Our non-invasive approach is essential when treating these significant and sometimes fragile structures, helping to raise, re-level and re-support the building with care and efficiency. Our highly trained technicians utilise a range of solutions and technologies to address the causes of structural subsidence, giving important buildings a new lease of life and preserving their historic integrity into the future.

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.
