Sub-bases and slabs poured, levelled and finished ready for screed, for a power float finish or for the covering going straight down. The layer nobody sees, and the one that decides whether everything above it works.
Dig, hardcore, blinding and compaction done before anything is poured. A slab is only as good as what it is sitting on, and that part is not worth rushing to save a day.
DPM lapped, taped and dressed up the perimeter correctly. Concrete does not stop damp on its own, and a membrane with a tear in it may as well not be there.
Floor insulation laid tight with the joints staggered, and edge insulation up the perimeter so the slab and the screed above it can move without cracking the finish.
Mesh or fibre specified for what the floor is going to carry. A domestic extension and a floor taking racking or vehicles are not the same slab.
Where the concrete itself is the finish, or where a coating is going straight onto it, the slab gets floated to a hard, flat, dust-free surface.
Levels taken off the drawings or off site datum, set out with a laser, and the pour checked as it goes so the finished slab is where the design says it is.
The slab is the structural layer, the part carrying the load. The screed is the thinner layer on top of it that gets the floor flat and takes the covering. Some jobs only need one of them, plenty need both, and we do the two so there is nobody to blame in between if the levels are out.
On any heated building, effectively yes, and Building Regulations will want it on a new floor. Getting it right matters more than getting it thick: joints tight, the membrane intact and the perimeter insulated so the slab is not bridged to a cold wall. We will tell you what the build up needs to be for your floor.
Concrete takes foot traffic in a day or two and reaches most of its strength in about a month. In practice you can usually carry on working on it well before that, so the honest answer depends what you are putting on it and how heavy that is. It is worth asking before the programme is set rather than after.
Yes. Barn conversions, warehouse refits, garage conversions and extensions where the old floor comes out are all regular work. Access decides the method: a pump where we can reach, barrowed and laid by hand where we cannot.
Breaking out, muck away and disposal can all be included in the price. Say so at the quote stage and it goes in as one figure rather than turning into an extra halfway through.
