With SR2, it is permissible for the surface to deviate from the straight-edge by as much as 5 millimetres. This classification recognizes that certain variations within this range are acceptable for commercial and industrial flooring applications. While the tolerance for deviations is slightly higher compared to SR1, an SR2 classification still ensures a satisfactory level of smoothness and evenness for normal flooring requirements in these sectors. It is important to consider the specific needs and expectations of the project when determining the appropriate SR classification. By adhering to the guidelines associated with SR2, contractors can deliver fit-for-purpose flooring solutions that meet the necessary standards and provide functional, visually appealing results.
- SR3 - In utility floors where the aesthetic finish is relatively unimportant, the SR3 standard is commonly employed. With SR3, the acceptable deviation measurement from the straight-edge can be up to 10mm. This classification recognizes that utility floors prioritize functionality over visual appearance. While the permissible deviation is higher compared to SR1 and SR2, it still ensures a reasonably level and even surface suitable for practical purposes. Utility floors, such as those found in industrial or storage areas, often prioritize load-bearing capacity and durability over cosmetic perfection. By adhering to the SR3 standard, contractors can deliver fit-for-purpose flooring solutions that meet the functional requirements of utility spaces while considering the cost-effectiveness and efficiency of the project.
In certain cases, it might be essential to engage the expertise of a qualified structural engineer to perform a comprehensive soundness test. This examination will evaluate the strength of the screed and its suitability for the intended purpose. The soundness test typically involves a "drop hammer test," which assesses different aspects of the screed's flexibility and strength. Given the specialized testing and measurement equipment required, only a competent structural engineer who adheres to the guidelines outlined in British Standards BS8204 should undertake this evaluation. The involvement of a structural engineer ensures a thorough assessment of the screed's integrity and provides valuable insights into its performance characteristics. This comprehensive evaluation process contributes to the overall quality and suitability of the screeded floor, guaranteeing its resilience and longevity.
