External Limestone Anti Slip Treatment for Entrance to City Bank London

Surefoot Systems applied External Limestone Anti Slip Treatment to the entrance of this international city bank in London, as it was extremely slippery in wet weather conditions. Pendulum slip assessment testing revealed that the slip resistance was well below the minimal required standards and the risk of slip accidents was high

On a Sunday whilst the bank was closed the surface was first deep cleaned using a speciality limestone cleaning agent applied by rotary scrubbing machine. The limestone surface was then treated with an invisible treatment to increase the wet slip resistance of the surface. Pendulum testing following treatment recorded that the slip resistance of the surface had been increased to well above minimum standards
