The concrete division at Aggregate Industries has unveiled a consolidated range of reinforcement solutions that are suitable for any beam or block flooring system. The company has stated that this will make it easier for house builders to specify compliant structural topping products.
This follows the implementation in January 2018 of the National House Building Council’s (NHBC) Technical Note 20 guidelines. The NHBC no longer considers acceptable the standard defined technical considerations around installing a beam and block flooring system. This is particularly with regard to the use of micro fibres as an alternative to steel mesh reinforcement. Instead, in order to be approved by the NHBC, structural toppings must use one of the following reinforcement options: macro ‘structural’ synthetic fibres, steel fibres, or steel mesh reinforcement.
Aggregate Industries’ range of NHBC-compliant structural topping products includes Agilia H for housing, which is a self-compacting structural topping that contains 4 kg of polypropylene macro ‘structural’ fibres, Highpave for housing, which is a concrete available in a range of consistencies and strengths, and which contains macro structural fibre reinforcement with 4 kg of polypropylene macro fibres. Finally, the company offers Agilia H, a self-compacting structural topping option that can be used in conjunction with steel mesh reinforcement.
“Beam and block floors remain the most popular solution for house builders when building a ground floor,” said Neil Cochrane, Specification Manager at Aggregate Industries. “However, the introduction of the latest NHBC guidelines have changed the parameters of what is deemed an acceptable reinforcement solution. As a market leader and major supplier to the housing sector, our focus is not only on providing the best quality solutions but also adding value – in this case by simplifying the specification process. Providing a clearly-defined range of NHBC-compliant options will save our customers valuable time, as well as provide them with confidence that, whatever their approach, the product will be acceptable to the NHBC.
The introduction of this range of concrete structural toppings forms a complete structural flooring system offer, including a bespoke beam and block solution from Charcon Construction Solutions.
