Custom In ground Pool Process

Here is my method of installing an in ground swimming pool. Generally speaking this is the process that I will follow when I build your dream pool.

Laying out the digging area for the swimming pool

First we will layout the swimming pool. There are two options for laying out the pool. The first one is a free form which doesn’t need to be parallel to to the house or “squared”, but a lot of reference stakes are needed for the multiple radius’.

The rectangle and various remnants (tee, roman end, H, etc) will need to be parallel to the house. In Butler and Hamilton county the local building codes says the pool has to be at least ten feet away from the housing structure.

The Pool is then checked to make sure the swimming pool is “square”.

Digging the in-ground pool

Here is my method of installing an in ground swimming pool. Generally speaking this is the process that I will follow when I build your dream pool.

Digging the swimming pool hole

A laser will be set up and reference point set up that represents the top of the pool wall. The bobcat will start taking dirt out, going 42″ inches in the shallow end and the deep end.

Once the whole pool is dug 42″ down from that reference point, the pool get gets painted. This time the pool is painted with at least 2 feet for the “over dig.” This over dig area gives room for plumbing, electrical conduits, room to work, and the braces for the wall.

A worker will go around the deep end and cut by hand in front of the line with a shovel. This allows the bobcat to be able to dig close to the line without losing the line. The slope gets dug, along with the slope for the deep end. These measurement will differ on the depth, length and width of the deep end.

The digging process normally takes two days, but sometimes with bad weather, or rocky soil (West Chester, Liberty Township, & Fairfield are known for very rocky soil)the digging will take three days.

Filter Pad

Normally the filter pad will get prepped on this day. The prep involves leveling the site and setting up concrete forms for the next day. The filter pad location is up to the home owner, but normally next to the house on the side closest to the skimmers is the best looking and most affordable choice.

Also on this day, if the pool gets a custom built steps, the first step will be formed inside the pool.

First concrete day

The next day, a concrete truck will come and a 6-8″ layer of concrete will be placed behind the pool wall. This locks the wall into place. After the concrete dries a perforated pipe will be installed around the pool for any ground water that accumulates around the pool.

Back-fill, plumbing and lights

Next an employee driving a big dump truck will start arriving with lots of gravel. We use a material called grits (or known as torpedo fill). This type of gravel can not be compacted which is important as the material will not settle like some types of gravel and especially dirt.

After small layer of grits are placed over the drain tile pipe, the plumbing will be ran. Normally a small trench will have to dug towards the filter pad. If lights are being installed conduits are also installed during this step. After plumbing is done, the back filling continues until the pool is completely encased with gravel behind the wall.

Concrete Forms

Then the forms are set up for where the concrete decking will be poured. After the location and heights are set, rebar is laid approximately 24″ away from each other.

Concrete patio pour day

Then, usually very early in the morning, will bring in some extra guys. We partner up with a local Cincinnati concrete company to help us out on this day as the concrete pour is very labor intensive. Sometimes ten guys are needed, while small simpler pours will require just 3 guys.

Vermiculite (bottom of the pool)

The next day we will come and start working inside the pool. We will clean up any junk inside the pool, drain the pool of all water and hook up a mixer. We will start mixing (normally 100 or more 40lb bags) of a material called vermiculite. The vermiculite will set up hard, but is smooth for the liner unlike concrete that has sharp edges that could tear the liner. We will place this material down on the floor and slope.

Haning the liner

Next step is the fun step….we take the liner out of the box and start to put the liner in place. Once we get the liner in everywhere we will start pushing the liner around to eliminate winkles. We will put a vaccum behind the liner to suck the air out and hold the winkles out. We’ll put the hose in and start to fill up the pool, normally to halfway up the first step.

The next day we come back and get out the last winkles and turn the water back on. This is the time that put the face plates on the lights, and the skimmer.
