EMJ Permadec Formwork Panels are primarily designed as permanent bridge beam infill shuttering. However, the many advantages of the strong, lightweight, steel reinforced glass fibre panels extends it's range of uses to sectors in the construction industry.


EMJ Sanquip products are lightweight and extremely durable. They are widely used throughout the UK and further afield in pubs, clubs, schools and major sports stadiums. Our GRP urinals and wash Washtroughs have been manufactured by EMJ Plastics since 1972.


On the A1 Leeming to Barton Project we have put strong emphasis on using reliable and quality supply chain. EMJ Plastics are one of the key suppliers on the scheme providing in-situ formwork for all our bridges. EMJ Plastics provided excellent service during the procurement, design and delivery stage which contributed to successful delivery of the scheme. EMJ Plastic's panels are of precise quality, light weight and able to accommodate change. I look forward to use EMJ Plastics products in the future again.
