Four reasons why Strategic Reinforcement is a more sustainable choice for concrete hardstandings

The built environment currently accounts for around 33% of the UK’s carbon emissions. With the country committed to reaching net-zero by 2050 – and targets in place to halve emissions in the built environment by 2025 – sustainability is already a key focus for many construction companies.
Matt Bollé, National Sales Engineer from Danley UK explores how strategic reinforcement can improve the sustainability credentials of projects which include industrial concrete hardstandings.

Back to basics: What is strategic reinforcement?

Poor joint performance and ineffective load transfer is a known issue in industrial pavement applications, causing cracking, faulting, performance issues and downtime. With a load transfer capacity of 90%, Danley’s PD3® tapered plate dowel and sleeve system provide more consistent joint performance over the full lifecycle of the pavement. The dowels are specifically designed to ensure that the concrete can shrink freely in both the lateral and longitudinal horizontal plane, without inducing restraint that leads to out-of-joint cracking.

By leveraging the high load transfer capacity of the PD3® tapered plate dowels at the sawn joints, and combining them with Danley® Dowels at the construction joints, Danley’s Strategic Reinforcement™ Design provides the highest deflection control tolerance in line with ACI 360R-10 standards, as well as complying with Concrete Society TR66 Rev. 1: External in-situ Concrete Paving and ACI 330.2R-17: Guide for the Design and Construction of Concrete Site Paving for Industrial and Trucking Facilities. Crucially, for those looking to improve the sustainability credentials of a project, the design optimises material usage and labour costs by removing all mesh reinforcement and placing steel at the joints, where it provides the most benefit.

Fewer raw materials:

Concrete is one of the most widely used construction materials in the world. In fact, the Global Cement and Concrete Association claims that it is the most produced and consumed material on earth apart from water. While properties such as thermal mass, cost, versatility, water and flood resilience, and durability mean that concrete is set to remain a popular construction material, it is also known to be responsible for a high percentage of C02 emissions.
Danley’s Strategic Reinforcement™ solution – which has been designed specifically to improve load transfer across all the joints in industrial concrete pavements – helps to meet the changing needs of the construction sector as it evolves towards a greener future, reducing carbon emissions by using less steel and concrete than alternative solutions. A recent project for Siemens Mobility Rail Project, saw Danley® value-engineer the original design of the external service yard, delivering impressive material reductions which amounted to a saving of 1330m³ of concrete.

Reduced transportation-related C02:

As well as delivering environmental and cost efficiencies by using less steel and concrete, the reduced use of materials also means fewer deliveries to site, further reducing transport-related CO2 emissions.
In fact, when Next Plc wanted to install a new pavement for a new external service yard at its warehousing facility, the 80% reduction in steel by weight, and 17.5% reduction in concrete by volume, resulted in eight fewer deliveries to the site, contributing to considerable carbon emission reductions over the course of the project.

Longer service life:

In any construction project, achieving a low-maintenance finish with a long life cycle is key to delivering a sustainable project. When it comes to industrial pavements, this combination of durability and an ability to withstand constant heavy loading at the joints offers a longer lifespan. By using Strategic Reinforcement™ to limit faulting, and cracking, users can extend the service life of the pavement. The result is a durable solution that requires less frequent maintenance, fewer raw materials and will produce less landfill waste over the course of its lifetime.

Meeting client demand:

The 2018 Smart Market World Green Building Trends report showed that client demands were rated as the most important trigger for sustainable construction practices, closely followed by environmental regulations. While sustainability is crucial to meeting legislative requirements and meeting the UK’s net-zero targets, at a commercial level client demands will inevitably lead contactors to opt for greener, more sustainable solutions.
