Technically Engineered Pools by Norfolk Pools

The pool construction experts in Brisbane

Most properties are not flat and, therefore, will need either additional out-of-ground formwork or site cutting and retaining walls. These days, it’s fairly common to see a pool with 1-1.5m of exposed shell due to ground levels. Pools in general need to be seated at least 600mm into natural ground, but in some cases the pool location means the pool shell will be nowhere near natural ground.

Norfolk has built many pools where the height of the pool could be upwards of 4-5m from natural ground level, and this requires a lot of technical and often complex engineering to ensure a safe and solid construction.

Project – St Lucia

Norfolk Pools St Lucia Project 01

The pool is located in the back garden between the residence and the river. To dig the pool, an excavator was floated into the riverbank and offloaded using ramps secured to especially installed fixings.

Due to multiple existing rock retaining walls, the excavator had to build an earth ramp up and over the retaining walls – Soil was removed using conveyor belts from the pool, over walls onto the pontoon and then loaded into skip bins located on a barge. Every 15 minutes the wash from the Brisbane River ferries would rock the barge and unbalance the conveyor belts, which meant each of the conveyor belts had to be stopped and restarted. The ferry pushed the barge down the river to unload the skip bins that were craned off the barge, and new bins reloaded then back to the site pontoon.

Care had to be taken at every stage to ensure that the existing rock walls remained undamaged and structurally sound. The rockwork from the wall above the pool was removed before excavation and then re-laid after the pool was complete. Footings were reinforced with piers so as to protect the structural integrity of both walls, and so the pool could be placed between them.

Project – Shailer Park

Norfolk Pools Shailer Park Project 01

Built on the side of a hill with a 35m slope on one side and 100m on the other, engineering was critical to secure the pool sitting 4m off natural ground level in place. Skill and experience was required in digging and forming this pool, with form workers having to harness up to secure formwork. Dark stone and natural timbers were then used to finish the pool, and form bridges and decking to integrate the pool into this stunning Koala habitat.

Project – Bardon

Norfolk Pools Bardon Project 01

This was a particularly interesting project to start. The client’s architect had some ideas that they presented to us but were changed when we viewed the property. There was only a narrow space between the deck and the side boundary, and although there was plenty of length, there was a 6m fall from one end of the deck to the other. The challenge was to maximise the use of the backyard while making the design as inviting as possible.

Due to the narrow width available, it did not make sense to lower the pool height away from the deck, as too much would be lost in staircases and the view over the water would be lost. For this reason, the pool was built to match the existing deck height, meaning at the highest point it was 3.8m out of ground, requiring retaining and careful engineering before we could start on the pool itself. We, as the builder, submitted a design that would give optimum use of the pool but also give the pool something that would make it a little unusual, which was done by using a negative edge on one end with a sunken deck that had timber benches that doubled as storage. 

Project – Fig Tree Pocket

Norfolk Pools Fig Tree Pocket Project 01
Situated in a quiet street and on a steeply sloping block, this pool was built 5m above the natural ground level by firstly building retaining walls and backfilling before we could form the pool. A glass viewing window was installed into the pool shell to give an outstanding touch to this design.

Project – Newstead

Norfolk Pools Newstead Project 01
Built right in the inner city suburbs, the pool is built several metres above ground and was constructed in conjunction with the house to create this gorgeous city facing aspect, allowing the owners to enjoy world class views over their own private waterfront.
