Why We Use a Gunite Bottom In Our Vinyl Liner Pools (video)

The Best Materials Make The Best In-ground Pools

In The video below you will our guys putting in the gunite bottom to a recent in-ground pool installation in Danvers Massachusetts. We like to call our pools a vinyl/gunite hybrid pool and this video shows you why. When watching the end opf the video note how smooth and solid the pool base looks. It almost seems like you could fill it now before even putting in the vinyl liner.

Why use gunite instead of vermiculite?

Vermiculite is the industry standard for vinyl liner pool bases, but that does not mean it is the best material to use. We believe that using a higher quality base material helps our customers pool liner’s last longer, and the shape and base of their pool to remain consistent for the life of the pool.

The gunite is brought in by truck dry in comparisson to a gunite pool where it is sprayed in wet and troweled. As we distribute the gunite across all the slopes of the pool we hand trowel it smooth, spray it wet, and trowel again. This process is time consuming but it is well worth it. When you are done the pool finish is smooth and free of rough spots that are common with vermiculite. It also hardens and cures harder than vermiculite which makes is much more resident to ground water washouts and pitting underneath the liner.

The extra costs incurred by using this method are well worth it in the end. Vinyl pools built with a concrete and gunite base will be stronger and last longer than those not built with this setup, not to mention a longer life out of your pool liner which helps keep cost of ownership down.
