Stronger well rings.
Delivered and placed.

• Strong enough to roll

  Rings that are small enough to roll get rolled: off the lorry, across the yard, over rough ground to the pit. Ours arrive in one piece. (The big 6½ to 9 ft rings are too heavy to roll. They go by crane.)

• Steel wire inside

  Reinforcing wire goes into the mould before the concrete, so it is cast inside the wall of every ring. Concrete carries weight well but cracks when it is knocked or bent. The wire holds it together.

• A richer mix

  We put more cement into every batch than most yards do, so the rings come out harder and denser. It costs more to make, and it is why our price is a little higher.

• Cast in steel moulds

  Steel gives the wall a smooth, tight face, without the rough, open patches where water gets in. That matters for a ring that will sit in wet ground for years.

How a ring is made

1. 01

   The mould

   Two steel shells are cleaned, oiled and closed together. For soakage rings, pins are set through the shells so the holes form as the ring is cast.

2. 02

   Wire, then concrete

   Reinforcing wire goes into the gap between the shells first. Then the mould is filled and left standing on the casting floor until the concrete has set.

3. 03

   Out of the steel

   A large ring still in its mould. When the shells come away they leave the smooth, dense face the steel gives, and the ring cures in the yard before it leaves.

Inside a cover slab

Once a slab is cast, nobody can see the steel inside it. These photos were taken in our yard while the slabs were being made.

1. 01

   Steel mesh

   A grid of steel bars is laid across the whole slab, with a form where the opening will be.

2. 02

   Concrete over the steel

   The concrete goes in around and over the mesh, so the steel ends up inside the slab, where it holds it together under load.

3. 03

   Openings cast in

   Square or round openings, for a manhole cover or a pipe, are formed in the mould as the slab is cast.
