Bridges

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. Bridge popularity boomed in the post-war era and now, the majority are reaching 60-70 years of age. However, 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 led the industry in providing construction, remediation & upgrade solutions to bridges for two decades.

Structural Repairs

As the world’s bridges and transport infrastructure continues to age, it is important to identify and plan for structural repairs.

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.

Expansion Joint Grouting

Bridge expansion joints are designed to reduce forces caused by external loads, shrinkage and temperature variations. They allow traffic to run continuously, nondependent on the conditions of the day.

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).

Bridge Bearing Grouting

Bridge bearing pads provide the supporting surface between the piers and deck of a bridge. The purpose of a bearing is to reduce the stresses involved in the controlled movements of the bridge.

Depending on the requirements of the bridge, 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.

Void Grouting

Void grouting fills all available spaces and cavities, adding strength to the weakest hollow internal segments throughout bridges. Void grouting also reduces the opportunity for corrosion and assists with load transfer between elements and into the substrate. This in turn increases the life span of the bridge.

For tight spaces that require a highly fluid grout, our contractors prefer BluCem HS200. It assists 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.

Post-tension Grouting

Bridge post-tension grouting involves the grouting of the duct surrounding tension cables. This provides 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.

Time Critical Grouting

In bridge applications where asset shutdowns must be minimised, BluCem HE80 (our high early strength grout) has been utilised for decades.

The specialised engineered cement system allows the grout to remain fluid during placement and ensures a high strength and durable, long term solution. We also supply BluCem HE80AG, a micro-concrete designed for larger, open applications.

Segment Match Casting

Segment match casting involves joining sections of preceding pre-cast concrete bridge sections which are joined to adjacent sections. This bridge construction process is the safest and most effective method currently used across the globe.

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 and is thixotropic, therefore easy to apply to precast segments and achieves 60MPa after just 24 hours.

Ground Anchoring

Ground anchors are restraining devices used in many different types of bridge construction from piles to abutments and foundations. Ground anchors are stressed (active anchorage) to prevent structural movement and are suited for strong rock conditions.

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.
