Bridges are the great civil engineering shortcut. Why go around, when you can go straight? Improving congestion, travel times and safety, bridges are a crucial part of the transportation network. Their popularity boomed in the post-war era and now, the majority are reaching 60-70 years of age. Many are in desperate need of repair and require clever solutions to minimise disruption. Government Authorities are looking to innovations which reduce closure times and minimise the cost to the community.
Our innovative range of products has lead the industry in providing construction, remediation & upgrade solutions to bridges for two decades.
An ever-increasing global population means that there is consistent pressure to expand the capacity of existing infrastructure. Rather than build new bridges, asset owners are choosing to widen bridges and increase overhead spans to add more lanes of traffic. Our range of fast setting grouts, mortars and concrete form an important piece of this complex problem.
Increased capacity also means that structural repairs to bridge abutments, piers and ground anchoring must also be considered to keep bridges safe and operational. We’ve been supplying an extensive range of temporary and permanent anchoring systems to major bridge construction and repair projects for more than two decades.
Products
BluCem HE80 and HE80AG are often specified by road authorities to secure steel movement joints (the large sawtooth style ones at the end of every bridge).
Products
Depending on the bridge’s unique requirements we offer several grouts which meet the range of stresses a bridge can exert.
These fast setting grout products have supplied to help our specialist partners throughout Australia, New Zealand and Asia for more than 17 years.
Products
For tight spaces that require a highly fluid grout, our contractors prefer BluCem HS200, assisting with pumping and penetration due to its fluidity, long pot-life and high final strength.
When grouting requires controlled placement in an open void, we recommend BluCem HS400 a thixotropic grout, typically used for void filling under bridge abutments.
Products
Bridge post-tension grouting involves the grouting of the duct surrounding post-tensioning cables, providing the necessary strength to transfer the stresses between the bridge tendons and cables to the bridge deck, concrete and surrounding ground.
There have been many notable global examples of bridge failures due to corrosion and failure of post tensioning systems. This is why Bluey Engineers have worked closely with road engineers and durability experts to develop BluCem HS200. HS200 conforms to global standards including EN447 and RMS R64.
BluCem HS200 uses the most advanced superplasticisers and suspension agents available to create an exceptionally high-performance post-tension cable grout. The grout ensures full encapsulation of the duct without bleed, segregation or presence of voids.
Products
The specialised engineered cement system allows the grout to remain fluid during placement and ensures a high strength and durable, long term solution. For larger applications, we also supply BluCem HE80AG, a micro-concrete designed for larger, open applications.
Products
Our BluRez Epoxy 575CG has been designed to meet the stringent performance and technical specifications often sought after in bridge construction. 575CG has an extended work time, is thixotropic and therefore easy to apply to precast segments and achieves 60MPa after just 24 hours.
We’ve supplied a range of multi-strand ground anchor systems to major infrastructure projects across Australia.
Permanent multi-strand anchors – fulfil their function for the duration of the working life of a structure and require comprehensive corrosion protection.
Temporary multi-strand anchors -working life up to 2 years.
Removable multi-strand anchors – temporary anchor (working life up to 2 years) with the strands being removed at the end of the working life.
