Concrete Spacers


 The fundamentals of making good concrete have been known since the nineteenth century, but not often used in reinforced concrete through the difficulties of placement, compaction and curing. Poor quality control led to rusting of the reinforcing steel and spalling (chip, crack or flake) of the concrete cover.

It is discouraging and alarming as we move into a new millennium that we  still hear of concrete structures with rusting and spalling problems.

To eliminate this weakness it is essential that the reinforcing bars be surrounded by sufficient impermeable concrete to stop them from rusting. If moisture and or air penetrate the concrete the reinforcing will then rust and expand, which will encourage the concrete to spall and reinforcing to be exposed.

PCP Concrete products Ltd manufactures of concrete spacers continue with an ongoing research and development program allied to production testing which keeps our product as the leader in eliminating the rusting and spalling problem so often seen in other non concrete barchairs. The superior performance comes from the poured concretes ability to bond around the spacer made of such compatible physical characteristics.

PCP Spacers use a waterproofing agent and as can be seen on the accompanying test report are able to exceed the stated 45Mpa figure we quote
