Vermiculite Pool Base | Edwards Pools

Want to see the process for how Edwards Pools installs vinyl liner inground pools? Watch this video showing the process from start to finish.

You will see the dig being done to the concrete decking being poured. Couple of things you will notice is how we install sump pits for ground water control, and the electrical work we can do ourselves, not through a sub-contractor.

This pool is a 16’x32′ with grecian corners on the shallow end. We installed Savi Melody LED color changing lights which do not require a wet niche. This also means there is no high voltage electric at the pool, only 12 volt.

Since this pool was finished late in the year, none of the landscaping was finished or grass growing yet. We’ll get the finished pictures once that is all done.

This is a short video showing the process when troweling the bottom in on a vinyl liner inground pool. You can see how we start with nothing but dirt and gravel, and trowel the base material over that untill the bottom is finished.

We use a vermiculite base rather than a grout base. Vermiculite sets up hard enough to walk on, but stays soft enough to be able to do any repairs needed. We can scrape any trowel marks, or repair any rough patches to get the bottom as close to perfect as possible. With grout (concrete) base you can not do this. Unless if a grinder is used any trowel marks or imperfections are permanent.

Vermiculite also allows water to flow through it back and forth. This allows for it to not crack like a grout mix will.

You can see the string lines we set in the bottom. This lets us trowel the bottom in exact so that our liners fit like they are supposed to. If you do not set string lines you are guessing at the dimensions, and there is a good chance your liner will not fit perfect.
