Filling in a concrete in-ground pool becomes necessary when it becomes too much to maintain, develops structural defects or outlives its usefulness. Filling in an in-ground pool requires a lot of time and work, usually requiring the help of a pool professional or demolition company. Filling in a built-in pool necessitates much more work than just piling on dirt and packing it in. This is not an easy job, even for a very handy do it yourselfer. Demolition companies use heavy machinery to break up and fill in it.
What to Do First
Check local town ordinances and obtain the proper permits.
Call utility companies and have them come and mark the ground around the in-ground pool, above the location of electrical lines, gas and water pipes.
Drain the water out of it or call a water company specializing in pool drainage. These types of companies drain the water from pools into their own tank trucks and haul it away. If you are draining to water yourself, remember many cities and towns won't allow drainage into a sewer system.
Safety -- First, Last and Always
Turn off the electrical power at the main box that leads to it and disconnect the wires from the junction box.
Disconnect the filter lines and remove the filter and set aside or discard.
Place 2"x4"s across the width of it at the depths, middle and near the top every 3 feet to shore-up the walls and keep them from collapsing while breaking up the depths of it. Once the bottom of it is broken up there is a danger of the walls collapsing especially if you live in an area where there is a high water content.
Use a jackhammer to break up the bottom of it, push broken pieces to the deep end.
Remove pool filtration pipes by cutting them out with a saw or disconnecting them with a wrench.
Use the jackhammer to break-up the concrete around it and push it into the deep end. Do not fill an in-ground pool with broken concrete more than halfway up it wall in order to allow the surface dirt to be used for another purpose.
Use a sledge hammer or heavy pick ax to chip away at the top 1/3 of it sides.
Back fill the hole with clean fill dirt to at least a 18 to 24-inch hill over the top to allow for settling. If you call a company to deliver dirt have them dump the dirt directly into it.
Tips, Tricks and Things to Keep in Mind
Consider hiring a demolition specialist to fill in it, but be aware they usually cost more than the installation of it.
Never dig without first calling utility companies, you can break gas lines and cause an explosion. You can also rip out electrical lines and get electrocuted or break water lines with is another very costly repair.
Wear safety glasses, hardhat, gloves and safety boots.
Do not build structures over a filled-in in-ground pool because the ground lacks the stability required for structures. W
