Transport and Infrastructure Solution

Transport Infrastructure, Airports and Ports and Roads and Rail

Transport infrastructure maintenance solutions

Mainmark’s ground engineering and asset preservation solutions are designed to re-support or rehabilitate civil infrastructure to enhance the safety and stability of ports, rail, roads, and other public infrastructure.

As roads, railways and port infrastructure ages, it becomes more susceptible to damage caused by the increasingly heavier loads of cars, trucks, trams and trains.

Repeated and intense mechanical vibrations, coupled with heavy rains or poor drainage, can weaken the ground under transport corridors, leading to possible subsidence and underlying voids. The resulting unevenness of hardstands and concrete slabs, road surfaces, railway lines and runways can present serious operational safety hazards. Mainmark raises, re-supports and rehabilitates large concrete slabs and damaged infrastructure. We also conduct abandonment of below ground infrastructure and voids. Works are undertaken cost-effectively while working around transport operations to minimise downtime.

Mainmark can:

	Raise, re-level and re-support public road and rail infrastructure using our proprietary Teretek engineered resin solution
	Fill large underground holes and voids quickly and cost-effectively with Terefil, our advanced engineered light-weight cementitious fill
	Revitalise, seal, protect and structurally reinforce ageing or damaged buildings and infrastructure including tunnels, shafts, basements and underground carparks impacted by weak ground and water ingress using Specialised Resins, Gels and Coatings
	Re-support and re-level large, complex public infrastructure using the award-winning JOG Computer-Controlled Grouting technique
	Compact and stabilise slopes and embankments to control erosion and provide safer site access using Permeation Grouting
	Rehabilitate, reinforce and extend the life of ageing or damaged manholes, pipes, tanks and drains with Specialised Resins Gels, and Coatings
	Improve and strengthen foundations of large public buildings using Jet Grouting
	Protect, seal, and revitalise concrete and steel asset using innovative spray-on corrosion protection solutions
	Rehabilitate and renew high-traffic and chemically-affected concrete slabs and road areas using Ultra-Panels, abrasion-resistant and durable pre-cast ultra-high performance concrete slabs

Barry, Kaikoura, Christchurch, NZ. September 2017

“I would like to take this opportunity to thank you and your staff. The project could have seriously impacted upon the business of the motel. Your solution to the structural problem of the pool slab resulted in a minimal intrusion to the business. The works were completed as per your stated timelines and your consideration of the guests as to when to commence and complete the works was greatly appreciated. You and your staff were both professional and polite, you left the site in pristine condition without a single drop of product to be found. Thank you for your prompt and professional work.”

Success Story:

Teretek® Stabilises Concrete Roadway at the City of Canada Bay

The City of Canada experienced concrete slabs suffering from various levels of deterioration; some were breaking up and needed to be removed and replaced, others required the voids that had formed underneath them to be filled to re-support the roadway and the slab joints sealed to reduce water ingress and water ponding. Mainmark’s proprietary Teretek resin injection solution was identified as an ideal option to help improve the lifespan of the pavement slabs.

Success Story:

Kaimai Tunnel Rail Slab Re-levelled and Bonded

During the 2018 Kaimai Tunnel upgrade, Mainmark was commissioned to use Teretek® resin injection technology to fill large voids that had formed beneath the railway slabs. TamPur, a specially formulated grout, was then used to bond the subgrade and cracked base slab and re-support the PaCT slab. Through early intervention, KiwiRail has been able to work with Mainmark to deliver a solution to prevent extensive damage to the tunnel floor which may have resulted in tunnel closure and a costly slab replacement.
