Hi all, I have a 12ft by 24ft lined swimming pool which I want to fill in. I believe the walls are pourous because its a lined pool. Ive been told to break up the base for drainage. I thought to use dtp1 to fill it with lots of compacting. Any tips ?

It largely depends on what is going on top? Driveway Lawn Patio?
You would most likely be faster filling it with clean stone as it won't need compacting, then capping with a geotextile and a layer of type 1.
Trying to fill an area that deep will require serious heavy weight compaction in order to avoid settlement. and it will take a while doing it in 10 inch lifts.

Contact your local skip hire firm, they will sell you some crushed brick and hardcore fairly cheap, it's £8 a ton upt north

they will sell you something alright
but it is unlikely to be clean crushed brick and concrete
can it not be demolished by a digger and pecker?

Form drainage holes in the bottom and fill with subsoil, compacting as you go, then topsoil the top 200/300mm
That's what we did back along and it's been fine.
