GRP Service Riser Void Solutions for High Rise Buildings

We are the leading designer, manufacturer and installer of steel-supported GRP riser flooring systems for high rise buildings both under construction and undergoing refurbishment. Our unique patented d2 system is Class B fire-rated, 20mm Ball Fall Test compliant, proven Live Load tested and up to 33% lighter than anything else on the market.

Our bespoke first-class safety, riser solutions on new builds or refurbishments together with our highly experienced team offer a tried and tested one-stop-shop for Riser safety – including design, material supply & install.

Riser voids (the openings which are left to accommodate mechanical and electrical services on multiple floors of a building) can provide real safety challenges for contractors. In the UK, the most common kind of fatal accident to workers continues to be falls from a height, being struck by a moving vehicle and being struck by a moving object, between them accounting for over half of all fatal accidents to workers in 2020/21. Data source RIDDOR (Health and Safety Executive).

Something as innocuous as a tape measure dropped from height in a riser shaft can tragically kill, and statistics show that a 500g object dropped from 15m has the same impact energy as a 75kg washing machine. Dura Composites offers a comprehensive Riser supply and install service utilising our purpose-designed Dura Riser GRP Grating products and galvanised steel framework to help reduce the risk of death or serious injury on construction sites.

Our Dura Riser solutions can eliminate the need for scaffold handrails, netting or timber shuttering and can be ‘Post-fixed’ or ‘Cast-in’ to concrete as a fully structural solution. From our d2 product range we offer Glass Reinforced Polymer (GRP) grating that meets the requirements of the 20mm Ball Falling Test, as well as versions with a completely solid surface for maximum debris defence.

Our Dura Riser Supply & Install Services

1 | Material Supply with Cutting Plan

The lightweight Dura Riser steel framework and GRP Dura Grating panels are so easy to work with and offer the perfect combination of strength, safety and adaptability on site.

The Dura system can allow for millimetre by millimetre changes and unlike competitor systems, there is no need to cut service holes ahead of time, or to crane heavy steelwork into position.

Alongside our supply only service we can also offer a quality assurance service for customers who are self-installing the risers. Our operatives can attend site to ensure installations meet safety sign off criteria.

2 | Design, Material Supply & Cutting

d2 Dura Grating can be supplied in full stock panels or pre-cut to size by our specialist cutting team. If you need design support, the Dura Riser design package includes layout drawings with secondary supports, and the option of FEA simulations and service cut out reports, covered under Dura Composites Public Liability Insurance.

We also have full design capability, offering PI insurance for bespoke designs. We use specialist software to plan and optimise pallet loading, and can label each load with a clear manifest and numbered panels indicating the intended floor level the goods are intended for. This saves valuable time on the project and negates the need to continually move items around the site to find the floor you need.

3 | Project Management, Design, Supply & Turnkey Installation

Our Riser Installation team are fully equipped and trained to install our bespoke riser safety solutions on high-rise new builds, refurbishments and other construction projects.

Our project management services will ensure that your M&E requirements are factored in at the specification stage to save you time and money.

Our GRP installation operatives are IPAF and PASMA qualified and our Sites Manager has also successfully completed the Construction Related Supervisory Technical NVQ Level 3 and holds the CSCS Gold Card.

Discover the benefits of d2 Dura Grating for your Riser Voids

Our unique d2 Dura Grating is up to 33% lighter than other GRP grating, for easier handling on site. As an example, our 38mm Standard Mesh d2 Dura Grating weighs 13.2kg vs traditional 38mm Standard Mesh grating at 19.5kg. The 6.3kg weight saving means better manual handling and labour saving benefits.

Designed, developed and manufactured by Dura Composites, d2 Dura Grating offers outstanding safety, performance and durability and is more cost-effective than traditional GRP grating in almost every scenario. It has an industry-leading Class Bfl-s1 fire rating as standard (in accordance with BS EN 13501). As with all our grating, it can be supplied with a range of stainless steel clips, clamps and hold down fixings to suit all install scenarios.

A comprehensive range of load testing data is also available within our searchable Online Product Selector database to help you make decisions based on real data to ensure maximum safety for your project.

  • Mini Mesh: 35mm, 45mm & 55mm
  • Standard Mesh: 38mm & 50mm
  • Solid Top (Covered): 29mm, 41mm & 53mm

Using a Dura Box as part of your Riser strategy

Our Dura Box cast in module is a galvanised steel permanent shutter for reinforced concrete slab, designed specifically for use in the riser floor building construction for complete piece of mind. Part of the Dura Riser system, the Dura Box provides an opening in concrete floor built to the correct bespoke length, width and height of each void and slab.

The Dura Riser Box can be delivered flat-packed for assembly on-site, or completely pre-built for lifting into place with maximum speed and minimum risk.

Opting for pre-built units can help on projects with shorter construction schedules where safety, quality, time and cost parameters still need to be met.

Our Dura Riser perimeter is fixed to the inside of the Dura Box for the Dura Grating to sit on, or the Dura Box sides can be made with a flange at the top for the Dura Grating to rebate into the slab.

Once the temporary floor is removed post-pour, the Dura Box is held in place with 100mm bolts that key into the concrete.

Our Dura Riser boxes are the perfect hassle-free solution that offers speed without compromising on safety.
