Mainmark are experts in building and infrastructure remediation and repair.
Our solutions offer sustainable and responsible outcomes that focus on preservation rather than replacement. This reduces the need for invasive, lengthy traditional underpinning or asset replacement works, that create environmental challenges in the methods used.
For over 25 years we have specialised in advanced, non-invasive soil stabilisation, ground compaction and foundation repair solutions to improve support for homes, buildings, roads, bridges and other structures affected by subsidence. We treat the ground beneath these structures to raise, re-level and re-support them cost-effectively. We are Licenced Builders and certified to ISO Quality, Environment and O&HS standards.
