Product Associations

British Precast members are eligible to join relevant product associations which provide a forum to address issues for a product or range of products.

Aircrete Products Association

  • The Aircrete Products Association (APA) represents the manufacturers of aircrete blocks who serve the majority of the UK market.

British Precast Architectural and Structural 

  • The group previously known as the Architectural and Structural Precast Association (ASPA) underwent a rebrand in 2017 to bring its brand identity in line with a number of other associations across the British Precast family. The 12 founder member companies have an impressive track record of projects delivering the spectrum of products from functional elements to decorative architectural panels that require no site finishes.

Concrete Block Association

  • CBA represents the vast majority of dense concrete block manufacturers in the UK.

British Precast Drainage Association

  • The British Precast Drainage Association (BPDA) is formed from the integration of the Concrete Pipeline Systems Association (CPSA) and the Box Culvert Association (BCA) and takes its place as one of the specialist product groups within British Precast.


  • Interpave is the trade association for the precast concrete paving industry in the UK, representing the interests of its members who produce around 85% of the UK’s precast concrete paving products. This includes concrete block paving, paving flags, kerbs, accessories and ancillary products used in the construction of hard landscape surfacing.

Precast Flooring Federation

  • PFF promotes flooring products across all building sectors, focusing on key benefits such as precast flooring’s excellent performance characteristics in terms of acoustics, fire, thermal mass and robustness, as well as speed of construction.

In addition there are also organisations affiliated to British Precast:


  • Interlay, the Association of Paving Installers, is the only independent trade association for concrete block paving and other modular paving installation contractors across the UK.

Modern Masonry

  • Modern Masonry is a body that seeks to ensure developers and designers, customers and occupants understand the benefits of masonry solutions. It provides guidance on design of masonry and furnishes government and influencing organisations with the evidence of how masonry can contribute to a sustainable built environment. It is supported by the Aircrete Products Association, Concrete Block Association and Mortar Industry Alliance.
