Marshalls delivers, with 15,000 linear metres of drainage to upgrade M1

Posted: Thursday 13th August 2015

Marshalls has supplied 15,000 linear metres of its Mono Beany one-piece combined kerb and drainage to the new M1 ‘smart motorway’ scheme, stretching over nine miles of highway.

Mono Beany is manufactured using ultra-tough M-Tech concrete and is available in two depths, both with a recycled inner plastic core to provide hydraulic flow benefits at low and medium capacities.

The inlet apertures are divergent and angled at 45° to prevent blockages and maximise drainage efficiency. These features ensure surface water is cleared rapidly and internal flow is smooth and efficient.

Each one metre unit can carry up to 40 tonnes (Class D400) when trafficked and the range comes with a complete suite of accessories, including outfalls and access units to provide a total system solution.

Marshalls also developed a bespoke transition unit for the scheme as part of the Highways Agency’s focus on innovation. The transition unit allows the scheme to meet the required hydraulic rates and came within budget without the runs being over-engineered. The unit now forms part of Marshalls’ standard linear drainage offer.

The installation time on this scheme was significantly reduced due to the easy-to-install system. This enabled the contractor Costain to install 340 linear metres per day, surpassing its initial target of 240 metres.

Alice Couldwell, Linear Drainage Product Manager at Marshalls said: “At Marshalls we recognise that there is a growing demand for cost-effective and uncomplicated drainage systems which has led to modern linear drainage becoming the preferred choice amongst engineers and contractors for improving highways.

“We provide a suite of water management products, including linear drainage with the innovative Beany range, and the UK’s leading Priora permeable paving, so you can have a complete water management solution for your project.

“Our Beany range combines the clear-cut advantages of combined kerb and drainage systems, with the benefits of a high quality, robust concrete which provides a number of competitive advantages.”

Malcolm Bell from Costain said: “Due to how quickly we were able to install the innovative Mono Beany system there was an increased demand on deliveries to site. Marshalls offered a reliable and guaranteed supply throughout the project, delivering three to four loads per week direct-to-site, often delivering two loads per day. This helped to ensure we met our completion deadlines.

“Working with Marshalls also offered Costain a dedicated and knowledgeable design team to meet our requirements for this scheme.

“These are all important factors when tasked with installing over nine miles of drainage to a major strategic route connecting people, communities and businesses.”

Marshalls has since supplied Mono Beany to the Bedale Bypass, described as the gateway to the Yorkshire Dales.
