Gappsi pools method of installing a quality pool liner starts with the installation of concrete walls swimming pools. 10 inches concrete walls are poured as the pool walls, then a 2 inches wide flange aluminum track is installed on the inside edge of the pool walls ,anchored on to the swimming pool walls with concrete screws secured in to the pre-drilled holes in to the concrete. Gappsi only installs hard bottom pool floors to prevent food prints to be made in to the pool floor when walking or jumping in to the pool. Foot prints are mostly seen at knight when the swimming pool lights are on.
Creating a not pleasant look in your swimming pool. Gappsi will install sand bottom at costumer request only. Another way of creating a pool bottom is by using vermiculite,
This is a pre mixed ready to use material that comes in bags and by just adding water to it is ready to be leveled. The down side to this product that we believe is not the best is because after changing many liners we found that vermiculite gets allot of mildew and it is not a pleasant site to see .the mildew comes from the cork that is mixed in the vermiculite mix and by being exposed to water below the pool liner and the dirt below, it builds up mildew. GAPPSI WAY to prepare the swimming pool bottom is by installing 3 inches of dry pack mix of fine sand and Portland cement in a 3 to 1 ratio. This is the best method for many reasons:
1= cement gets stronger over time when exposed to moisture
2= does not build up mildew
3= it can be leveled to be perfectly smooth
4= if the liner needs to be changed in the future the cement base done by Gappsi will not need to be fixed or replaced .
Preparing a cement dry pack pool bottom floor, take a lot more work then any other method and a lot more experience and a much larger crew of people.
It takes average 10 yards of sand to complete the floor and this need to be mixed with cement and moved in to the pool and leveled.
It is very hard to mix the cement and sand in a dry form because it as to me mixed several times before it is used.
The skills of the personal that can build a dry pack cement swimming pool floor is far more then any other method because it as to be done uniformly thought the pool floor .
the results of a hard bottom cement floor is a very clean and flat perfect crispy look of the swimming pool floor liner especially at night when the lights are on.
And if not built consistent, any imperfection will be very visible.
