Digging the hole, January 2011
If you think that you can do the excavation, think again! The geology of this area means that we have 18″ of topsoil and then straight into sandstone rock the size of billiard tables.
February 2011: The Swimming Pool full of the wrong water
Vanzay has a very high water table, meaning that the hole immediately filled with ground water from the bottom up. Here there is almost 1m of water and progress was delayed for 8 weeks waiting for the water table to drop. There’s little point in pumping it out, since the pumped water merely returns to the water table!
March 2011: Finally, work resumes, structure assembled and pouring the concrete
After the concrete had been poured the structure on which the liner hangs is now very strong. Reinforcing is used throughout, including down through the hollow panels that snap together to create the sides which are then also filled with concrete.
March 2011: It now looks like a swimming pool - after a fashion
Now it was a question of waiting for the concrete to go off – about 2-3 weeks. It was also time to suffer the consequences of the local geology, since in the absence of soil from the hole, 60 tonnes of calcaire was needed to backfill. You can just see the first 30 tonne delivery in the access way behind, dropped where the articulated lorry got stuck!
The reinforced concrete base to the terrace
We had a notional deadline of 1st April for the pool opening and so whilst the concrete of the pool itself was going off the base of the terrace was laid. A good deal of concrete for an 85m² terrace.
The pool liner is now in
Following the application of a screed to facilitate a very smooth finish (so as not to snag and tear the liner) the liner was fitted. This can only be done when the air temperature exceeds 16°C to ensure that the liner is pliable enough to be fitted.
Filling the pool
If you look very carefully you can see a single hosepipe running over the steps into the pool. We began by just using tap water, since we had read varying opinions about pumping well water to fill swimming pools. After two days of pitifully slow progress, as well as disruption to the water pressure into the house and gîtes, we employed a second hosepipe connected to the (powerful) well pump. After a further day we had a full pool, made up of about 60% mains water and 40% well water.
April 2011: The swimming pool is almost finished
The technician arrived in the second week of April to commission the pool. This involved enabling the saltwater filtration system, the pompe à chaleur (heat pump) and demonstrating the regular maintenance and water testing/treatment steps. This photograph was taken from water level to omit the unfinished terrace and the rough surround pre-landscaping.
May 2011: The terrace is completed with 340 patio slabs
To lay 85m² of patio slabs in 27°C and direct sunshine – since forecast temperatures are taken in shade it was probably more like 35°C – is extremely hard work. Two very skilled and hard working friends helped for a total of 9 days to complete this job. Thanks to Brett, Donna and Drew. We wanted a large terrace to provide plenty of space for those who like to just sit or lie by a swimming pool in the sun.
The way to the swimming pool
Yet more calcaire was used to create the pathway……..
June 2011: The newly seeded grass borders and finished shower point
……. to keep folk off the grass. The grass took some time to thicken due to very hot days and no rainfall. Even if there had been a hosepipe ban at this point it is permitted to freely use well water.
June 2011: Project completed.... the swimming pool is now open
That was a big undertaking and we’re glad to now just lounge on the terrace in the sunshine and take a dip when it all gets too hot!
After dark, with the church of St. Jacques lit up in the background and pool lights on
