A garden
Cracked concrete taken out, riven porcelain and a sleeper edge in, and the lawn turfed.

Porcelain and natural stone, laid on a dug and compacted base with the edges held. The layers you never see are the ones that decide whether it is still flat in five years.

The soft ground comes out first, deeper than the finished patio will sit, and goes away. Crushed stone goes back in and is compacted in layers until it does not move under the plate. The slabs are bedded on that, each one tapped to a line so the finished surface falls gently away from the house. The edges are held, by a sleeper, a brick course or a kerb, so nothing can creep outwards. Then the joints are filled.
The photograph beside this is a patio halfway through: the first slabs down on their bed, the sleeper edge going in, the gravel margin waiting. That is the stage nobody shows you and the one that matters.
Most of what we lay now is porcelain. It does not stain, it does not grow moss the way natural stone does, and it comes in large formats that make a small garden look bigger. It is harder to cut and it has to be laid on a full bed rather than on dabs, or it sounds hollow and cracks.
Riven sandstone and limestone still suit a lot of the houses round here. They weather, which some people want. The sequence on the groundworks page is a riven sandstone terrace from the churned ground to the turf.

Anyone can lay the last inch
Four layers, and you only ever see one of them. Tap a layer to read what it does.

The only layer you will ever see, and the one that gets judged.
The layer the slab actually sits on. It sets the level of every slab in the patio.
Crushed stone, compacted. This is the layer that carries the load, and the one that decides whether a patio is still flat in the second winter.
The ground that was already there, once the soft stuff has been dug out and carted off.
If a quote comes in a lot cheaper than the rest, ask what depth they are digging to.
Where we have the same spot before we started, it is tipped into the corner.

An old concrete slab patio out, dark porcelain in, laid larger than the one it replaced and stepped down to the lawn.


The old slabs and the loose gravel taken out, porcelain laid to the doors and run out to the lawn with a gravel margin at the edge.


Cracked concrete out, riven sandstone in mixed sizes down, two sleeper planters built and the lawn turfed.
