In this time lapse video, Penguin Pools is using Pool Krete from Strong Manufacturing to pour the bottom of an inground vinyl liner swimming pool.  By using the mixer from Strong along with their specialty pump, we are able to do the entire pool with 3 guys.
The mixer makes it so you get perfect consistency the entire time you are pouring the bottom.

Do you have clay as your soil base?
Do you have a high water table?
Do you just have water issues?

Water takes the path of least resistance and will essentially find any gap around your pool to fill into.  If you have a high water table or a soil base that doesn’t allow water to run through it easily, you can get what is called a “floating liner”.  When the ground water pressure is more than the water pressure inside the pool, it essentially pushes the liner off the vermiculite bottom.

The pool water in the pool didn’t have enough pressure to hold back the ground water.  While this can happen to anyone that doesn’t have enough water in the pool, it can also happen when your pool is completely full of » Continue reading “Sump Systems – The Correct Way to Prevent a Floating Vinyl Liner (video)”

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.

Rule #1 :: If you are putting in an inground swimming pool, never use sand.  If you are talking to a builder who only uses sand, politely say thanks and escort him out of your house.  Using sand is easier, less expensive, less messy; but it is also just being lazy, suck in 1980, and not good for the end user.  Simply put, you are working with someone who isn’t concerned with making the best pool possible.

Strong Pool Krete is made up of Portland cement, vermiculite, and sand.  When all three are combined and troweled out, you get a strong smooth surface for your liner to lay on.  Pool Krete will setup and turn into a hard “cork board” for your liner.
