BRE testing in construction is the testing of various materials and products to published standards, ensuring they are suitable for specified use. Heat & Screed Ltd now offer a screed BRE test service (also known as a drop hammer test) using our own BRE test equipment.
Specific to our company and what we do, this is a test for soundness of floor screed which can be affected by a number of variables including; poor compaction, moisture content, insufficient binder (cement).
The BRE test is carried out using a device, which consists of a 1m long, cylindrical guide rod, along which an annular weight of 4kg (or 2kg for floating screeds) travels when released. At the bottom of the guide rod the weight strikes the collar of a casehardened 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 depths of the indentations are then measured with an electronic depth gauge. Any area where the impacts produce an indentation of 3mm or less can be considered sound, according to current data. Where the indentations are greater than 5mm the screed may fail when in use.
We can offer solutions for failed floor screeds including: the removal and re-laying with fast setting and drying products or the use of specialist penetrating resins.
