Reactive clay that moves with the seasons
Much of the higher ground around Caboolture and Morayfield is reactive clay, which expands in the wet summer and contracts through the dry winter.
A shell and surrounds that are not designed for that movement can crack, and the repair costs more than getting the engineering right the first time.
We check the soil before pricing and specify the reinforcement and shell for the ground we actually find, instead of quoting off a satellite image. Reactive soils are the reason a poured shell suits this region so well.
