    Light location and depth

    Thanks. There doesn't seem to be too much info on installing the conduit from the lights. I have 3 lights and they are all home run to the panel. From what I can gather, they will come out the back, 90 straight up and then run a couple inches below the bottom of the concrete above the...

    Sand as Steel Wall Backfill

    Hi, PB is recommending backfill of steel walled vinyl inground pool with sand. Most recommendations I have seen have been for 3/4 inch clean rock. There isn't alot of discussion I can find on using sand, except for fibreglass pools. Is sand a good choice? Why or why not? We are in an area...

    Dig profile before or after wall erection

    So I dug the profile before wall erection as the PB wanted some crush down as a base. Curious if I can fully dig the area between the shelf and the hopper prior to putting up the walls and if so, should it just be a straight line or convex/concave slightly?

    Overdig a little too small

    Hi, When I sprayed the overdig for my pool, I sprayed 2 foot. Since the walls are not exactly plumb straight down, I have somewhere between 1 to 1.5 feet at the bottom grade instead of the requisite 2 feet. Do I need to dig this all out to 2 feet+ around the entire perimeter, or can I just...

    Main Drains in Sport Pool

    Hi, just a question about main drains. Is there an issue having main drains in a vinyl liner sport pool where the center is only 5.5' deep. I am worried mostly that people will stand on them. PB thinks I should have them and I agree; but not sure if recommendations are different for shallower...

    Crush Rock under concrete pool bottom

    Hi, I am building a steel wall inground sport pool. I am having a PB come in to build the walls, pool bottom and collar. The pool bottom will be concrete. The PB has recommended I overexcavate 2 inches and put in 2 inches of crush rock as a base for setting the walls and the concrete bottom...

    Dig profile before or after wall erection

    Yes that's Correct. Only about a 15000 gallon pool. How do people usually go about laying out the pool (finding points a,b,c,d and others)? Do the just measure to two points with masons string and drop a plumb; or is there a better way.

    Dig profile before or after wall erection

    Hi, We are building a kidney shape sport pool. Depth goes from 48" to 64" to 48" starting at 7 feet from each end of the 32"X18" pool with 2 feet in the middle at max depth. It seems overly difficult to try to determine exactly where the slope and deep part should be without having the pool...
