The set-out for the excavation is the first critical part of the construction process. Sometimes the set out is a fairly quick process particularly with freeform pools, however, sometimes the process is quite time-consuming depending on things like squareness to the house and boundaries, critical finished heights and correct clearances form services. Excavation commences once we have agreed the set-out (or outline) with you.
Handy Hint: In most cases the material which is dug up (spoil) has to be transported away from the site. To reduce costs, you might find a suitable “free tip” in your local area where we can take the spoil.
At the end of the excavation, a layer of drainage gravel is spread across the floor of the pool.
Approx time: 1 - 5 days
After the excavation, formwork is placed around the pool up to the height of the finished concrete. We will take great care in accurately placing the formwork as the concretors use this to measure off , giving accurate lines for the inside of your pool shell.
Once the formwork is in place, the steel reinforcing bars are bent and placed inside the formwork and excavation. The correct placement of these steel bars is critical for the strength and longevity of the pool shell, even though in a day or two they will never been seen again.

The process of installing the concrete to a swimming pool is called “shotcrete” or “sprayed
the process of pneumatically spraying concrete. Typically, the concrete is brought to the
in large trucks, then pumped by a truck-mounted concrete pump to the pool area. At the end
the hose air is introduced to the nozzle and one man carefully sprays the concrete into
After a few minutes, helpers (concrete shapers) are able to trim and shape the concrete into
a form that is suitable for the final finishes.
Handy Hint: Although great care is taken with the concrete process, it is still a somewhat messy process. If at all possible, it is better to delay other trades such as painters and fencers until after the concrete has been placed.

Once the concrete shell is installed, the plumbing can be installed. This can often be done at the same time as the Stage 5 Coping and Tiling, or sometimes after. This will not effect the finished product and is scheduled to best suit your project.
There are three types of pool filters: cartridge, sand and diatomaceous earth (D.E.). Each of these filters have advantages and disadvantages, so it is important to have some understanding of this to make your choice of preferred system.
Chlorinators and Chemical Balancers
Most pools require chlorine to kill bacteria as well as acid to lower ph to a level where chlorine is effective. Exceptions to this are ozone pools which are generally not viable in domestic situations. The two common systems are salt chlorinators and chemical feeders like a “Chemigem”.
Salt chlorination is the process of manufacturing chlorine by electrolysis from salt. This is the most common way of chemically treating backyard pools in S.E. Queensland. Because of popularity, salt chlorinators are manufactured in large volumes making them quite inexpensive to buy and operate. These days, most salt chlorinators are self cleaning, removing the chore of cleaning the white build-up off their cell. Acid needs to be added by hand to control PH.
Chemical Feeders ( “Chemigem”):
Chemigem is one brand of chemical feeder. Typically, chemical feeders electronically measure chlorine and PH levels in your pool and automatically add chlorine and acid as required. This ensures more pure water with a more perfect water balance. Unfortunately, these machines are more expensive to install and maintain.
Handy Hint: We are happy to help you with the selection of your plumbing and filtration as it is important to select materials that suit your pool’s conditions, your budget, and the longevity of your pool. We have years of experience in working with the different products over time.

After the concrete has been placed, the coping (tiles or pavers on the top of the pool) and tiling (some pools have tiles placed around the inside at the waterline) can commence. This is a very important process as you will be looking at the quality of the finishes and workmanship for many years to come. The pool interior can now also be applied.
Approx time: 3 day
There are many different pool interiors available in concrete pools, all with advantages and disadvantages.
Handy Hint: We are happy to help you with the selection of tiles, pavers and interior finishes as it is important to select materials that suit your décor, your budget, and the longevity of your pool. We have years of experience in working with different products and finishes over time.
Next, the pool is filled with water. The cost of your pool can include a water tanker which we arrange to come and fill your pool. This takes approximately one day.
After the pool has been filled with water we vacuum your pool and chemically balance the water. Once we are happy with the job we will make an appointment to hand-over the pool to you. This will take approximately one hour of your time so that we can properly explain the care of your pool.
Total Project Time: Approx 8-12 weeks**
