Ground floor (concrete topping) – Tarmac Topflow HZ

Tarmac Topflow HZ
Topflow HZ is a self compacting, easy finish, free-flowing concrete resulting in a smooth, level surface capable of accepting most wearing materials directly without the need for power floating. Topflow HZ flowing concretes are self-compacting, so once they are placed there is no need for manual vibration. The concretes smooth surface is achieved through a quick dabbling technique to the concrete to push the coarse aggregate below the surface. The final touches are achieved by using a spray on curing membrane to seal the concrete and trap moisture in.

Question mark

Did you know?

Fact 22

If zerocarbon standards were adopted across the UK they would avoid emissions of 26 MtCO2 compared with continuing to build to 2006 standards. This is why it is imperative that we make sure that builders and suppliers know what is needed and how it may be achieved as they plan construction.
