Waterproofing, Enhanced
Patch Repairs - M25

Value: £900, 000

NEC3 contracts/options used: Option C

Start-finish dates: Ongoing

Main project team members: Jackson Civil Engineering, Connect Plus, Techjoint.

Scope and significance of project:

Our client, Connect Plus asked us to develop a way of repairing damaged waterproofing on bridge decks and permanently reinstating the carriageway within the time constraints of a standard night time closure. Conventional waterproofing materials require optimum weather and temperature conditions for installation, which often result in project delays and increased disruption to road users. Our trials and subsequent use of a new waterproofing material Matacryl, have reduced installation times and increased reliability on such projects.

Please detail how you demonstrated collaboration on your project:

For many years now, Jackson Civil Engineering has worked as both a tier one supplier on the Highways England network and more recently as a tier two supplier for clients including Connect Plus, EM Highways, Ringway Jacobs and Amey. On joining the Connect Plus team it became apparent early on that the nature of their long term DBFO contract over 30 years would allow us to deliver their schemes with a long term view on the best procurement option. This long term contract was the driver for us to work with our supply chain, to focus our energy on providing solutions with the best whole life cost. One example can be cited through the development of the use of a waterproofing agent Matacryl, which we first trialled on the M25 Mardyke Viaduct. Our client, Connect Plus asked us to develop a way of repairing damaged waterproofing on bridge decks and permanently reinstating the carriageway within the time constraints of a standard night time closure. Conventional waterproofing materials require optimum weather and temperature conditions for installation, but through our initial trial, we found Matacryl to be far superior, as the curing process is a chemical reaction that can be sped up using a catalyst.

The colder the ambient temperature, the more catalyst can be added, making it far more versatile than conventional materials. It can also be laid as quickly as you can walk the length of the area. Our initial trial of the material was highly successful, proving Matacryl’s superiority over conventional materials, and it’s potential to reduce delays and installation times. However, we faced a real challenge in sourcing the material due to a lack of suppliers in the UK. Through close liaison with the manufacturer, and our client Connect Plus, we enlisted the help of one of our longstanding supply chain partners, Techjoint, and encouraged them to get involved. The collaborative nature of our relationship with Techjoint gave them the confidence to diversify their business and invest in the necessary plant, equipment and training to become the lead installer of Matacryl. Mark Healy, Managing Director of Techjoint explains: “Following the trial, we had a meeting with Jackson and Connect Plus about the possibility of us becoming regular installers. Both teams had knowledge of the system and kindly offered advice and support.

As a result of this continued advice and support, from both Jackson and Connect Plus, we have been fortunate to become the lead installer of this product, and we’re currently working across the Highways England network in areas 2 & 3, for TfL, on the M25 for Connect Plus, and on various other contracts. Techjoint as a business is relatively new, and as a result of the collaborative nature of our relationship with Jackson and Connect Plus, we’ve been confident enough to invest the development of new products. The team are always there at the end of the phone if we ever need any advice, even on competitor’s projects and this is something that is unique in our business. Some of our new products and ideas have come as a direct result of the team pushing us in the right direction and offering advice or help to achieve our goals as a company.”

The spirit of mutual trust and cooperation that exists between us, our supply chain and clients has provided an environment in which we can develop our own staff and supply chain to increase capabilities and meet the wider programme needs of the UK’s highway network.
