Uretek has completed over 10,000 projects in Australia and New Zealand, which include several restorations of the foundation ground in heritage buildings involving re-supporting and relevelling the footings.
Bluestone, sandstone and brick are common footing materials found in heritage structures in Australia. Uretek’s solutions have helped achieve positive outcomes for these footing materials as well as the more modern concrete slab and strip footings.
Uretek employs their unique and patented process of Deep-Injection in these heritage restoration projects by renewing and increasing ground support for the old structures. Most of these heritage jobs involved a wide range of stone or brick footings, but a few had virtually no footings at all.
Building height and weight is typically no problem for Uretek since immense, controlled pressure can be used when required.
The Deep-Injection process produces lifting movement, which is constantly monitored by laser level. The process involves raising the ground to bring the footings back on level rather than applying expansive pressure directly to the relatively small elements of the footings.
The resin technology also causes the wall cracks in heritage buildings to close up as the footings are re-levelled, following which only plastering, painting or re-pointing of outside brickwork is required to complete the restoration.
Uretek has restored ground support, undertaken crack repairs and re-levelled many historic buildings including churches, schools, town halls and cottages in Australia. Uretek’s overseas work includes restoring the foundations of castles, cathedrals and ancient temples.
