Utilising Calcium and Silica to Redefine What a Structural Sewer Lining Shotcrete Is

The BluCem ZeoGlass formulation includes the use of two, non-traditional concrete materials; Calcium and silica. These supplementary cementitious materials (SCMs) not only reduce our environmental impact, but the SCMs also improve the durability of the structural sewer liner.   Calcium: Conventional geopolymer concretes will not activate in the presence of Calcium ions, yet Calcium is […]

Filling Cracks with Injection Grout – Here’s What You Need to Know

Repairing cracks with injection grout helps provide waterproofing and corrosion protection. Check out the BluRez range of epoxy and polyurethane resins.

Concrete Topping To Industry-Leading Standards

The BluCem RF20 is ideal for a number of applications including levelling concrete floors and resurfacing rain damaged slabs.

Choosing the Right Concrete Repair Mortar for Patch Repairs

Cementitious patch repairs are a necessary and effective solution for strengthening concrete structures, areas of which have become defective or spalled.

Basement Waterproofing – An Art in Protection

Basement Waterproofing – An Art in Protection: While many people in the construction industry associate Bluey with just tunnelling, it isn’t the only sector that we are experienced in. At first glance, basements aren’t similar to tunnels in shape, scope, dimension or even use, but when water is involved, the consequences are very similar indeed. […]

The Polyurethane Injection Resin that Expands 50x in Size

Bluey’s BluRez CSW polyurethane resin can be used in a number of environments, from dams and embankments to retaining walls.

WestConnex News: New Design Plans for the WestConnex Twin Tunnels

The Sydney Metro project continues to move ahead and details of new design features for the WestConnex link have been released.

ZeoCem: The Binder That’s Increasing the Design Life of Our Cementitious Range By 3x

More than 90% of Australia’s sewers are lined with OPC concrete, which deteriorates when it comes into contact with harsh acidic environments. The repair of these assets is an ongoing challenge for owners and government authorities as the existing network is suffering widespread attack. This is because regular OPC liners cannot suppress the metabolism of […]

Modulus of Elasticity of Concrete & Mortars

Modulus of Elasticity of Concrete: From the wide range of opinions about the best performing materials to the dozens of available products, the selection of concrete repair materials is a highly complex and challenging task. Depending on the application, the key drivers of performance can be categorised as either; durability, structural or aesthetic performance. This […]

Ensuring TBM Compression Gaskets Resist Natural Groundwater Pressure

Until recently, terminating cross-passage membranes to TBM segments had been one of the unsolved mysteries of tunnelling. Thanks to recent innovations in gaskets and pressure terminations, all hydrostatic forces can be resisted to ensure they meet the ‘no damp patches’ specification. The most challenging part of any cross-passage termination is ensuring the membrane connects and […]
