Pier Replacement

This house is in the Launceston area and required 40 new piers.

Here you can see the old timber piers, sitting on the edge of the concrete pedestals. Most of the timber piers were rotten at the bottom and were tilted and unstable due to the concrete pedestals moving. The floor was propped prior to removal of old piers.

Pier Movement

This house in the Hobart area, had a mixture of brick and timber piers that were sitting on the existing clay, without a concrete pad. We supported the existing floor and removed the sub-standard piers. We excavated and poured new concrete pads and fixed new galvanised steel piers in the concrete and to the timber bearer. Working height for this job varied from 900 mm to 300 mm.
