This is what happens with the water is moving to fast, not to much or to little, but to FAST.  This happens when pool builders over size a pump for a pool or when return lines get plugged up.

Having a pool company that understands water movement and how it relates to the overall good of your pool is key.  Pump sizing is key for correct water movement along with proper filtration.  Bigger pumps can also push the water right past your filter media not cleaning properly.

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.

When using sand under your vinyl liner is doesn’t hold its form as well as Vermiculite.  The sand takes years to get fully packed down and not move anymore.  HOWEVER, before it packs down you can feel waves and even make indentations with your heel in the sand.  I am sure that you have been swimming in a pool when you felt their was a gap under your feet.  That is from the substrate, sand, moving or creating divots.

Some people, not many anymore that I know of, that also use concrete under the liner.  While concrete is strong, it is very rough and grainy.  The concrete can never get as smooth as the vermiculite and in turn it will slowly rub the underside of the liner making it weak.
You may not feel it, but each time you take a step on the liner it will move a little.  If you don’t have a smooth surface it will rub the bottom of the liner raw.

Above ground swimming pools are generally less expensive and move for the budget minded consumer.  Adding sand to the bottom is usually preferred as it is less expensive.  Using Pool Krete instead of sand is going to cost about $1,000 – $1,500 instead of the $300 for the sand.

Using sand in an above ground pool is more acceptable as it is more budget minded.  Inground pools need to last for 50+ years and more times the vermiculite will only need minor patching each time you replace the liner . . . every 15 or so years.

Simply put, if you want a perfect bottom for years to come use Pool Krete on your pool bottom.  When it is done, and done correctly, you will see how perfect the liner will fit.

Many consider pool building as a summer project. But building during the cooler months brings a number of advantages. You will find that out-of-season swimming pool pricing can be very favorable indeed, providing some significant savings over the prices charged during the peak months. The availability of the swimming pool that you want is another factor that is influenced by the time of year. You’ll find it easier to find the exact pool that you want during the low-demand period of the year. Also, delivery and installation can be more favorable outside of the peak summer months.

The big advantage is that your new swimming pool will be ready to use as soon as the weather turns that little bit warmer in the spring. As soon as that warm weather appears you can be sure that your swimming pool supplier and installer will be immensely busy with a backlog of orders and installations to fulfill.

My advice to anyone who has been toying with the idea of having their own swimming pool installed in their garden is to gather a few quotes from reputable swimming pool suppliers now. You should be able to negotiate a substantial discount and get yourself a bargain swimming pool installed and ready for some summer fun.
