Uretek Ground Engineering with many years of experience in raising and re-levelling roads and buildings, have very successfully re-levelled several large, concrete in-ground swimming pools for local government authorities.
Re-levelling large concrete pools is tricky business because the pressure of lifting could break through the pool bottom or push apart the sections of an articulated pool. However, Uretek’s engineers figured out the solutions to such problems and have proved their techniques in practice, re-levelling some very large pools.
A recent example is the twenty-five metre long public pool at Monto, Queensland. It had sunk two-hundred millimetres at the deep end. This prevented the flow of water required for the filter system to function properly.
The pool was constructed from precast concrete sections. The walls were precast with flat bases. Precast concrete infill sections formed the floor. Floor joints and vertical joints were filled with mastic.
This required extremely precise, careful lifting. Over-lifting any one section could rupture the joint. And the wall could easily rotate inwards or outwards due to its large precast base.
Moreover the floor slab was on a step joint. So the internal slab could not be lifted. That could have caused the slab to lift at the joint. Each precast section of the wall had to be lifted in turn a little at a time.
Uretek very gradually brought the pool back very near to perfect levels. The correction of the levels was proved by the flow of water in the gutter. Uretek then carefully filled the voids under the internal pool slab.
North Burnett Regional Council’s Trevor Harvey congratulated the Uretek team on an excellent result.
