Strong Pool Krete Mixer & Pump – Vermiculite Mixer for Pool Bottoms
Vermiculite is the preferred base for vinyl liner swimming pool bottoms as they require a smooth, level, & nonabrasive base. Strong is the leader in vermiculite (pool krete) for the swimming pool market. Strong premix pool krete is easily applied and gives a perfectly formed bottom so the liner will not slip or wrinkle. All of the pools that Penguin Pools builds in the Milwaukee, WI and Minneapolis, MN area, have vermiculite bottoms.
Along with just doing vermiculite bottoms on all of our inground vinyl liner pools in WI, MN, & IL, we also apply it with a special mixer and pump from Strong Manufacturing. The mixer and pump give us a perfect consistency throughout the entire pool so we don’t have to worry about some areas being too dry or wet. The time that it takes us to pour a bottom has been greatly reduced, and we have 10% – 15% less waste then with a simple paddle mixer. Penguin Pools is also able to keep the site cleaner as we have over 75′ of hose, so we can keep the mixer away from the house in the corner of your site to minimize the clutter & mess.
Penguin Pools also re-pours bottoms for older pools that had original sand bottoms. The key to a good inground vinyl liner replacement is a solid base. In the Milwaukee, WI & Minneapolis, MN areas we do a ton of vinyl liner pool replacements that are damaged do to a bad or poor subsurface.
In the SE WI, Penguin Pools does pool bottoms, for various pool companies in the region who due not have the equipment to do them as quickly or efficiently as us.
* Vermiculite is must easier to apply to steep side walls & will not wash away with changes in water tables.
** Vermiculite forms a monolithic, permanent, cast and will always remain in place.
*** Vermiculite becomes an insulating barrier from the cold temperatures of the soil beneath it.
