Complex Ironworks Reinstatement with Zero Compaction or Hot Works
Case Study
Problem
Wales & West are responsible for the maintenance of many Ironwork assets.
They are proactive in improving their efficient service, by being open to new
innovative solutions.
A twin, double cover Ironworks had previously received
some maintenance works months earlier, but it had further deteriorated and
was now rattling, causing disruption for the nearby residents.
One of the
biggest challenges faced with this Ironworks reinstatement was the covers, positioned less
than 150mm apart, meaning no compaction could be applied within this zone,
causing an inherent weak point.
The impact of ineffective repair solutions for
Ironworks, can increase the ongoing cost, use more resources and develop to
become a greater problem.
Solution
Meon supported Wales & West with the installation and suggested using our
HardMaster, Rapid Set Concrete Bedding and Back Fill System, topped off
with our revolutionary Asphalt Repair Solution, PermaFyx L273.
By using the
HardMaster W620 Bedding Mortar and HardMaster W621 Flowable Backfill
Concrete, the narrow channel between the 2 covers was no issue and PermaFyx
L273, requiring zero compaction, was the crowning touch.
The repair was
sealed with UltraCrack L270, to help prevent the ingress of water into the repair,
maximising its durability and longevity.
All the systems used are cold applied, so
no hot works equipment was required for completion of the repair.
Result
Local residents were able to benefit from a safe, effective and efficient Ironwork
repair. The finished result is a very secure, well protected Ironwork, with a quick
service time, the repair was open to traffic in just 90 minutes.
The chemical
reaction bond strength, achieved with our Cold Applied Rapid Set Concrete
and Asphalt Repair Solutions requires zero compaction, hot works or heavy
equipment, allowing for ease of application and minimal disruption to the local
road network.
Due to its high strength and durability, this ironworks will outlast
several more years than traditional repair systems.

Magma UltraCrack L270 | MMA Overbanding & Crack Repair Kit
UltraCrack is an MMA crack repair which is a cold plastic product that is designed for crack infill and overbanding.
As with all MMA products, it is very fast-curing, which makes it ideal to live traffic situations where road closure time needs to be kept to a minimum.
It is very durable, enabling permanent repairs which will outlast the surface itself, extending the life of surfaces by resisting the inflow of water and minimising damage caused by freeze/thaw.
