| The BRE Tester is designed to measure the soundness of a sand / cement floor screed as early as 14 days after laying. The device consists of a1m long, cylindrical guide rod, along which an annular weight of 4 kg (or 2kg) travels when released. At the bottom of the guide rod the weight strikes the collar of a case-hardened steel anvil which transmits the impact to the selected area of the screed. Four successive impact blows on the same spot are sufficient to test the soundness of the screed.
The depth of indentation is measured with an digital depth gauge. Guidance is given on the use of the screed tester for testing floating screeds using a 2kg annular weight in place of the 4kg weight normally used. This weight is now supplied as a standard part of the screed tester kit.
