We just demolished an old tin shed and what lies below is an extremely unhappy concrete base - some pics attached for amusement.
The plan is to self-build a mega-shed/workshop (approx 10M x 4.5M) on a timber frame but the levels in the current concrete are so poor it's not usable as a base. I think my current options are:
1.) Drill down into the existing concrete base in a number of locations to install legs or piers which can be individually levelled.
2.) Shutter the existing concrete area and do an additional pour on top to bring to a level.
3.) Try to get the new floor frame level by some combination of propping up with bricks/shims in the low spots.
4.) Something else I didn't consider yet.
The site is at the end of a ~100M garden with no road access for concrete so anything involving breaking up or even pouring more concrete is low on the agenda.
Any advice welcome!
