Why is it better to own a vinyl liner in-ground swimming pool in New Jersey than a concrete or fiberglass in-ground swimming pool?
It basically comes down to water chemistry and New Jersey weather. Here we get 100 degree heat in the summer to below 0 winters. If the chemistry of the pool water is off balance, it could steal minerals from the concrete walls deteriorating your actual wall. On fiberglass, it has a tendency to crack very easily. Fiberglass is very expensive and only comes in certain shapes and sizes. Weather tends to create both movements of the ground and ground water. This can cause the concrete pools to move, crack and leak, where as vermiculite and liner pools tend to take underground water and movement very well. Vermiculite is porous, keeping it from cracking, and the vinyl does not get eaten up by bad water chemistry as easily as a concrete pool.
