Preserving History
Mainmark’s Proven Non-Invasive Solutions
Mainmark has delivered successful results for many building owners, including those identified as heritage-listed or 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.
Mainmark’s solutions and technologies are particularly well suited to address the the causes of structural subsidence, giving important buildings a new lease of life and preserving their historic integrity into the future.
- Correcting subsided stone and brick footings. As Teretek® resin injection does not require excavation, there is no risk to damage of the footing with stones/bricks dropping into the excavation
- Improving ground beneath the existing footings prior to an extension being built
- To provide targeted ground improvement to weak sub-grade soils
