Uk Screeds Ltd16 Jun, 2022Business

Measuring the flatness of the surface of a screed is carried out using a two-metre straightedge and a slip gauge to measure any gaps underneath it. The results are defined as SR1 (Surface Regularity 1), SR2, and SR3. In order to achieve SR1, the maximum gap at any point along the two metres must be no more than 3mm and is known as High Standard. SR2 (Normal Standard) allows for a maximum of 5mm, while SR3 (Utility Standard) allows for 10mm.
