There are many drainage aspects to this project.: A plethora of drainage locations Long drain behind the upper retaining wall to prevent water placing pressure behind the wall.

We finally had the plumber here today to repair and reroute the pipes that were “discovered” during the excavation. Because they connect to the public utility, we’re not permitted to repair the pipes ourselves, but we can (and did) prepare the trenches for the new route, so it was just a matter of laying the pipe and cementing a few connections.

But everyone who hears these words of mine and does not put them into practice is like a foolish man who built his house on sand Mathew 7:26 And yet sand is a popular base material under foundations :P

As with the concrete footings, the pool shell can’t sit on bare earth. Popular base materials include sand, small screenings (i.

With the pool base compacted, screeded and ready, it’s time to put the shell down. The pool site itself is in the back garden and there’s no access for a crane so we’ll be lifting it over the house from the street.

70-tonne Liebherr mobile crane arriving It’s time for step two of moving the pool shell into place (step one being already complete).

After completing work on the compacted base for the retaining wall footings, it’s time to make preparations to pour the concrete footings themselves.

534 meters of bar plus mesh to be precise. As discussed during the detailed design, the retaining walls and wall footings contain a lot of steel.

We covered cutting and bending in the first-part of this two-part post. Now it’s time to place the bent, cut, steel with the help of chairs and ties.

A pool’s plumbing system is designed to keep the water clean and hygienic. It consists of one or more suction fittings in the pool that draw water and debris in, a bunch of equipment located somewhere near the pool that processes the water, and one or more returns, where the clean water flows back in to the pool.

Suction and return fittings As explained in the pool plumbing design post, we have a skimmer and two wall suction fittings to extract water from the pool and three return eyeballs to return water.

With the 3D design to guide me, I set about building the pump/filtration system and connecting all of the suction and return pipes.
