Inflatable Pool Uneven

Suggestions for a base inflatable children's pool?

We buy the kids a round inflatable pool for the summer. The problem is not can be set for them in the garden because the ground is uneven and the level of available area is occupied only by your trampoline. I would like the base be temporary – concrete and cobblestones outside. Some thoughts I had were: 1) The construction of a base structure full of sleeping 2) Construction a framework of sleepers and the use of PLAYWOOD / yellowtongue for a base, covered with high strength plastic to withstand outdoor exposure to sun damage and Rain The above options can be expensive, so any other suggestions would be greatly appreciated. Greetings, extravagant

builders sand – can be purchased the bag in the building supply store or get a truck in a yard of bricks when you're finished with it can be spread on the patio level
