Nine Mile Point, Industrial Estate

Starting at the end of 2020 and finishing in January 2022, the waste facility’s size and purpose required a robust flooring solution, able to cope with the high impact and abrasion entailed in its end use.

Approximately 1500 m3 of concrete was required at Nine Mile Point Industrial Estate. The mix specification was proposed by Konfloor Ltd with Breedon and Sika then developing a mix design, powered by Sika concrete admixtures to fit the brief.

Konfloor Ltd determined the need for concrete with high workability, neutral set properties and which could be finished using a power float, thus producing a hard-wearing, smooth and level surface finish.

Concrete was supplied over a five-day period and Sika’s contribution came in the form of a new flooring admixture and the dry-shake surface hardener and fibre suppressor. Sika® ViscoCrete®-150 PF – a liquid superplasticising admixture for concrete - was dosed at the location and was chosen to help maximise durability whilst achieving the desired finish using a power float. Allowing for high workability, tightly controlled air content and with a neutral effect on setting time, Sika® ViscoCrete®-150 PF is ideal for this application and meant Konfloor Ltd could start the finishing process after just two hours.

Enabling high compressive strength, the formulation of Sika® ViscoCrete®-150 PF promotes improved cohesion as well as early and ultimate strengths. A combination of these benefits meant it was a suitable option for this specific project. 

In addition to this, Sikafloor®-FibreShield, a synthetic dry shake hardener for concrete, was utilised alongside 40 kg/m3 of steel fibres and Sikafloor®-ProSeal W, a one-part water dispersed acrylic emulsion, was applied in order to cure, harden and seal the surface.
