I am sinking my kids circular trampoline into the ground so the mat can be flush with ground level. The trampoline is about 4.3m in diameter and about 1m high so that represents the approximate size of the hole I need to dig. I need to line the pit I dig so that it doesn't collapse in on itself. I was going to use standard engineering bricks but am concerned that the bend radius will be too tight to use bricks. I will be grateful for any general tips regarding this job but specifically want to know if there is a minimum 'radius' of curved you can build with standard bricks. Many thanks.
