Sand Not Compacted By Installer
My family recently had a pool put in and the people we had install it didn’t do a great job.
There are big divots in the sand underneath the liner, even a screw on its side under the liner which feels like its going to come through any day now and near the cross brace (its a 15x25) I can literally step into a hug divot between the beams.
Okay, the installers screwed up. But what do I do now? I purchased some underwater patches but that’s only a band aid. I'm thinking the liner needs to be taken off, maybe replaced, and the sand underneath needs to be addressed, right?
How do you cover those cross beams underneath with enough sand that the weight of the water doesn’t push through the gaps?
It's really sad, we waited FOREVER for the town to get the permit ready and had to spend a fortune for surveyors and alternate septic tank location.
Groan. I'm enjoying the pool but I feel it won't last long.
An uneven bottom should not be a problem safety wise, I mean, it should not collapse. The liner will probably not last as long, cleaning over lumps and pumps will take its toll on the liner.
What you want to watch out for are the sink holes around the brace assemblies. You do not want the liner coming into contact with the sharp metal edges of the channels or straps. If this is happening the pool should be drained immediately.
The only reason sand would be sinking around the braces would be because the installers did not pack the dirt in well enough. The brace assemblies should be back filled with dirt and sufficiently tamped. Extra sand is used to cover the pressure plates, and plenty of it, but the braces need to be set in packed dirt.
You might want to keep the liner in the pool for as long as you can stand the lumpy bottom or for as long as you think it is safe. It is possible to drain, smooth, and refill with the existing liner but using a new liner will usually give you a better job.
