Dipping Pool in April 2016

Note: I would like  to share with  you  through  these few words, photographs and hyperlinked websites, a 3 Dimensional  experience as though you were  actually there with  us. Click on any photograph and it should enlarge to  different size ….. at least half screen or size full screen. It will be clearer in detail than the photo on the post. It will be as if you were  really there looking at the actual  scene. You are an arm chair traveller with us.

This is a process description of the dipping pool as it is being constructed over several months. It isn’t a swimming pool as this  would be very expensive to construct and  would need a much bigger space. A pool would need to comply with many  council regulations and special inspections. It would need a big fence around it to make it safe. We just wanted  a pool that we could go to near our house, have a dip in water in  the hot summer weather, get cool and come out again.

April 2016: We are really enjoying the cooler weather. In the last week, we had a small mini – excavator and Bobcat (which came together) out for the whole day … digging out a new dipping pool. It is neck deep with a rounded bottom.  The mini – excavator had a rock attachment  which picked up a heavy 1.00 metre granite rock and moved it to the other side of the pool. Three big granite rocks had been roughly placed as leftover boulders from a landscape job  from twenty years ago. It was the rock on the far side which was moved.  See the photos above.

The  excavated pool  will be lined by spraying earth – coloured concrete so that the clay and  rock  base are not apparent. This will be reinforced with a Polypropylene fibre.  We will then fill it with bore water over a night and day.  It will be used as a natural dipping pool in the hot Queensland  summer period. With frequent  topping up  with bore water, the water should be relatively clear. In the past I’ve seen it running 100 mm deep over this area with torrential rain.  Any excess site runoff water will now flow around the pool and boulders to flow under a level driveway bridge and down into the paddock below.

In May, I have been laying new brick paving in old onsite bricks pulled up from some paving I had done years ago in the main front garden.  The paving had to sweep down the path in line with the path through the Permaculture Garden Room.

Then it changed to an area of basket weave  paving at the pool level. This pattern has been around for centuries and can be seen decorating ancient European towns. The basket weave pattern can be thought of as a checkerboard-like pattern that is composed of pairs of bricks. The bricks are laid horizontally and vertically against each other to create the visual effect of them weaving in and out of each other. This is a very eye-catching pattern, and is appealing in patio or entertainment areas within your landscape. See the photos below.

I am going to repeat the same pattern on the other side. My son Anthony is helping by  working in with me  by  laying complementary  hardwood demolition timber stored on our land from when I ran a  twenty year business in landscape and construction.  We are having a wonderful time interacting with each other.  I haven’t done this sort  of work for twenty years.

See these posts:  MY PAST WORK

The other day Anthony  bought a big drop saw  that  can easily cut through big 75 mm thick hardwood  timbers. He is starting to cut and  lay the  heavy hardwood demolition timber as demolition timber paving  that meshes in with the new  brick paving. See these photos  below.

What Anthony started off with … a pile of demolition timber ….. which piece goes where? That is what  he had to work out.

A deep gully or trench was dug to run site runoff water around the back of the boulders.  Site runoff is then run into a big pipe which is already in place under the  existing small  timber bridge across the exit driveway. See the photos above. The basic work was finished  in July 2016 …..

Spraying the dipping pool with concrete in October 2016

We had our friend John Tunstall come out to look at how to spray the dipping pool with concrete. John has had many years of difficult and very  intricate  landscape construction work since 1959 and is he now retired but he knows so much about construction. He built all the stone walls in our house  35 years ago. See this post on building our house in 1981

The excavated pool was lined by spraying earth – coloured concrete so that the clay and rock base were not apparent. This was reinforced with Polypropylene fibre rather than steel mesh. This enabled the finished product to have a very fluid and rounded finish instead of a more rigid vertical finish.

A shallow gully or trench was dug to run site runoff water around the back of the boulders and pool. Site runoff water would then to run into a big pipe which is already in place under the small timber bridge across the exit driveway. As of January 2017, the plan is  to lay black plastic about a 0.75 metres wide in the shallow gully. This would be topped with heavy river gravel (stones to 75 mm in diameter). This would make it look as if a dry creek goes around the back of the pool.

See the photos above. As of October 2016, the pool was half full of muddy water, but John bought a new submersible pump to which we can attached a long hose. When set up, we then pumped all the water out and let the pool dry out enough so we could spray the pool with concrete. We then  filled it with bore water and used it as a dipping pool in the hot summer weather in December and January.

Construction Sequence:

A small mini – excavator digs out any mud and leaves on the bottom of the pool. This is so the pool can be sprayed with 100 mm of concrete the next day (just as well we didn’t have a thunder storm that night !!).

A 100 mm layer of gravel had to go in the bottom of the pool before it was sprayed with 100 mm of concrete the next day.

The  concrete pump trunk in place for the concrete supply truck to come in at the right time. Timing was so important as the concrete pump trunk had to booked a week ahead as they are so busy.

IMG_8531

All the boulders are covered in plastic sheeting so no boulders would be contacted  by concrete spray. John organised all of this.

The concrete supply truck  comes at the right timing …. mobile phones are very useful !! It the right amount,  earth – coloured concrete and polypropylene fibre mix and  (a very non standard mix). John organised all of this.
