British Precast are urging contractors to check any installed precast concrete drainage products amid concerns of uncertified components

British Precast has discovered that a range of imported precast concrete drainage products such as manhole rings, manhole covers, seating rings, corbels and gully raisers are being placed in the UK market without visible proof of third-party verification or assessment of conformity to relevant European and British standards. As a result, customers can have no confidence in the performance of such products. Third party verification systems are crucial to our industry as they ensure a product's quality, durability and safe performance in service.


A number of UK industry specifications, such as 'Sewers for Adoption', 'Civil Engineering Specification for the Water Industry' (CESWI) and different highways' standards and manuals, require specific precast drainage products to conform to relevant provisions of British Standards such as BS 5911-3. This can only be assured through third-party certification such as BSI's Kitemark scheme. The industry has a responsibility to demonstrate their products to be safe for their intended use.

Colin Nessfield, Technical Manager of British Precast, advised: "Customers, and others in the product supply chain have a responsibility to ensure that the precast drainage products they purchase have the necessary 3rd party assessments and certification, which is the minimum required by the Construction Products Regulation. Ignoring these requirements plays into the narrative that elements of the construction industry are still unconcerned about product safety, quality and client satisfaction."
