Like the best magazines, this article consists mainly of pictures - as it is nearly Bank Holiday weeking and I am heading off to a Camping Barn near @recoveringacademic's place with friends. The problem is straightforward. About 5 years ago on moving to the current house I had a 8' by 8' shed constructed in a corner of the garden which consisted of (perceived) well-packed rubble from many years ago. We used a base of concrete fence-posts laid flat to allow some minimal give, and room to expel any unwelcome undershed-dwellers, and to avoid the extra expense of a full concrete slab. How wrong I was. The ground turned out to be as movable as a slow-motion mattress, probably due to the rubble not being as compacted as thought, heave from a nearby tree, and a succession of extreme summers. The thing seems to move by up to a couple of inches at one end or the other up or down depending on how the weather, the tree and the rubble are changing. And the shed has needed adjusting twice since it was put in, and it still looks wonky. A further issue was a frame on the shed not quite strong enough to prevent shear distortion (ie the roof moving sideways relative to the base to give a rhombus shape.) I decided to use a product from ASP Wallbarn called Adjustable Support Pads, in this case their Megapad product which supports 1500kg per pad, and which give nearly 4 inches of vertical movement on each pad. These were installed under the existing posts using a couple of trolley jacks and a bit of digging. The pads can be adjusted after installation. The cost for 8 pads delivered was just over £70. If you order these or similar from online trade or retail sellers, then you may well be much more heavily clobbered by expensive shipping costs. I ordered these over the phone from Wallbarn, and they even reduced the £15 shipping cost to £7; the products arrived the next morning. Total time taken was about 6 hours for one man. This photo shows the full range of adjustment, and the component parts. The shed as it was on Wednesday morning Leaning to the Left. Wedges and a door that has not been lockable for some time Doing the job Levelling Up Correcting the shear, and installing a new brace Job Done. I hope. Will it work? Ask me in a couple of years, when the ground has moved again. Total cost was under £200. A new shed plus a concrete slab would have been about £1000 or a little more done professionally with careful sourcing. The chap doing the work is the excellent John Smith of Little John Property Services (M: 07702 033296), who does a lot of property maintenance for me.

I have to praise Wallbarn, the supplier of Adjustable Support Pads (aka to me as Patio Feet), who have just given me superb customer service. I have used their Megapad Extra version .. adjustment range 125m to 210mm, pic to be added.Spoke to them yesterday after the shipping deadline, but they got them here by 9am this morning for a shipping cost of £7, and a total price of £70 for 8. And we have used them today. Excellent service, and a lot of robust product for a competitive price. Very happy. The photo shows the pads at their lowest (125mm) and highest (215mm) for this model, which will carry 1500kg each. Cost about £6.20 + VAT ordered over the phone. I will post a thread or a blog about what we used them for. Ferdinand

In the past I have recommended Wallbarn for Adjustable Support Pads. An interesting product new to me is now available which self-levels for up to a 5% slope. https://www.wallbarn.com/products/balance-pedestals-paving/ I may use this or one of the competitors for my shed which has self-unadjusting foundations.
