Interlay, the Association of Paving Installers, is  the only independent trade association for modular paving installation contractors in the UK and works in support of the good installation of both commercial and domestic paving.
Interlay provides regular support on technical matters, updates on changes to rules and regulations, as well as other industry news, through newsletters and members’ meetings. The Association has a multi-platform website supporting mobile and tablet technologies and an active Twitter feed @Interlay1.
Interlay staff and members, with support from Construction Skills, Interpave and other industry leads, contributed to the development of the National Highways Sector Scheme (NHSS) 30. The scheme is aimed at improving the installation, maintenance and repair quality of modular paving constructions. A web based dedicated hub detailing the training and support available to installers is hosted and maintained by Interlay ( and Highways England now requires the use of registered installers ahead of non- registered ones wherever they are available.
The National Highways Sector Scheme 30, ‘The Quality Management of the Installation, Maintenance and Repair of Modular Paving’, seeks to improve the installed quality of all types of modular paving including concrete blocks, flags, kerbs and ancillary products used in road construction. The Scheme aims to provide an industry benchmark, ensuring project processes are planned well and use properly trained and competent installers, verified by vocational qualifications and supported by the introduction of a CSCS card. Focusing on continuous improvement, quality of installation and reduced ongoing costs for both clients and suppliers, the scheme was developed by a dedicated technical advisory committee. This includes representatives from across the paving sector - including clients, contractors, manufacturers, suppliers, trade associations, training organisations and certification bodies, with Interlay providing the Secretariat and logistical support.
