Screed standards and tolerances
The work of a professional screed layer is based on accuracy and specialist knowledge - it is not for nothing that all statutory regulations must be observed. In today's article we deal with the screed standards and tolerances and the meaning behind the legal regulations.
DIN18202 - That's what it says
This rule deals with the height differences that two arbitrarily chosen points in a certain distance can have. This value is called "flatness tolerance" and is explained in more detail in DIN 18202. The following values result from table number 3 line 3:
row | Reference | 0,1 m | 0,6 m | 1 m | 1,5 m | 2 m | 2,5 m |
3 | Ready-to-use floors (e.g. screeds, industrial floors, bonded screeds, etc.) | 2 mm | 3 mm | 4 mm | 5 mm | 6 mm | 7 mm |
The table created above is only an excerpt from DIN 18202, which, however, refers to the evenness tolerance when laying the screed (finished floors). The top line shows the distance between two reference points in meters. The highest possible tolerance for the respective distance is in millimeters in the line below.
Example: Before we start laying the arch covering, a visual inspection and, if necessary, a random check of the evenness tolerance is carried out. Two points are selected at a distance of one meter. The height difference at this distance may not exceed 4 mm.
Conclusion: Screed should always be laid by a specialist company
In order to prevent nasty surprises, standards and tolerances should be observed when laying screed. This is difficult for laypeople, since the necessary equipment is usually not available. However, since the professional laying of screed has a direct impact on the comfort and functionality of your floor, this work should be carried out by a specialist company.
