Topfloor is a low shrinkage concrete for use in ground bearing slabs. Extremely durable, with very high abrasion and impact resistance, it provides superior flexural and compressive strength, without the need for steel or mesh reinforcement.

The mechanical and shrinkage properties of the concrete enable the design of thinner and unreinforced slabs, with increased joint spacing at 20 x 20 m (400 m²). Construction can be shortened through early power-trowelling and joint cutting, while slabs can be loaded from just 14 days. The drastic reduction of joints, limited curling and high surface durability combine to deliver savings in maintenance and whole life costs.

Features and benefits:

  • Highly durable, requires no surface treatment and has a high abrasion resistance achieving BS 8204–2:2002.
  • Fast to lay and load, cost effective with reduced maintenance and material costs and more sustainable reduced CO2 emissions by up to 20%.
  • Reduced shrinkage to 250–350 micro metres per metre.
  • Topfloor can be fully recycled at the end of its life, due to the absence of steel reinforcement.


  • Waste and recycling.
  • Warehouses.
  • Factories, industrial and commercial floors.
