It’s important to point out that using this method to add a sandy beach can only be done if the organic pool has a sloping edge much like you will usually find at the coast or a lake. If you want to add one to a pool with vertical sides, you’ll need to build a containment area — effectively a kids’ sandbox. It wouldn’t be difficult to do with some boards and short 4×4 posts for supports, but you couldn’t have the sand actually running into the water in a natural way. Any sand that spilled over would simply sink to the bottom of the pool.
Even when the swimming pool has sloping sides, it could swallow an awful lot of sand. The solution, as David illustrates in the video, is to build an underwater wall or baffle so the sand doesn’t need to cover such a large area or be as deep.
David is working with an existing regeneration zone, but has removed the plants. If your layout is different, you’ll probably want to create an initial barrier, and use gravel to bring the bottom of the pool up a couple of feet.
