Geotechnical

Across a number of environments, the ground can become weak after being exposed to excavation, weather events, infrastructure changes, soil movements or even seismic activity. Not only can changes in ground conditions create a risk to the general public, but they can also be extremely expensive to replace the damaged infrastructure. This is where our ground support products can be of great advantage.

With the right Bluey product, we can provide confidence that regardless of the application, the ground can be supported in a safe and effective way. Our innovations in this area ensures that this part of the industry is keeping up with the additional demands of bigger cuttings, deeper tunnels, longer spans and other challenges faced due to growing populations.

Corrosion Protection
In most tunnel environments, double corrosion protection is specified to ensure that contaminated ground doesn’t affect the design life of the underground structure.

BluGeo GRP60, is our innovative solution to corrosion protection. As GRP is made from a glass fibre polymer, it doesn’t require the amount of excavation to install double corrosion protection, meaning >50% reduction in excavation and grouting.

We’ve also developed a highly acid-resistant thixotropic grout, BluCem HS400Plus, which is used for the grouting of anchors to reduce the effect of contaminated ground.

Tunnel Bolting
When it comes to the success of tunnelling projects, tunnel bolts play an essential role. We’ve developed a low-profile bolt which provides cost and productivity savings, a lower environmental impact and a higher-quality end result.

The BluGeo LP Tunnel Bolt has a low-profile head for both permanent and temporary fixture for tunnelling infrastructure. Designed to be used in tandem with the BluCem grout system, the tunnel bolts can meet and exceed 100-year durability requirements. If you’re looking for a temporary or permanent tunnel support solution, BluGeo LP Tunnel Bolt is the solution.

Ground Anchoring
Ground anchors are effectively restraining devices used in many different types of underground construction. Ground anchors are stressed (active anchorage) to prevent structural movement, commonly referred to as tension anchors and are suited for strong rock conditions.

We’ve supplied a range of multi-strand ground anchor systems for more than a decade, including:

  • 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.

Grout Curtains
Grout curtains are used in below ground applications where the excavated soil and rock can pass dangerous levels of water seepage. These curtains reduce the amount of water passing through the ground, ensuring a safer site and less delays to subsequent activities.

BluCem HS200 and BluRez CSW have been designed for the sealing/grouting and elastic connection of concrete cracks, rock fissures, brickwork and natural stone. Applications include subterranean curtains as well as tunnel linings, foundations and retaining walls. BluCem HS200 is a preferred alternative to microfine cement systems due to its exceptional penetration capabilities and higher strength gains.

Rock Grouting
From stopping water seepage to consolidating loose rocks, BluRez CSW has been a game-changer for the civil industry over the past two decades. CSW adds use-life to tunnels, embankments, dams and retaining-walls where battling with water is an ongoing issue.

BluRez CSW reacts with water in a matter of seconds and can stop high water inflows. This makes the product ideal for sealing leaks under high pressure in tunnels and basements. CSW is also highly elastic, allowing for a range of environmental conditions including movement from rocks, concrete or water.

Spray Concrete
For underground projects, shotcretes are used for overhead, vertical and horizontal applications. To save time and cost of expensive formwork systems, we see projects specifying spray concrete systems which provide fast cycle-time and other advantages such as chemical resistance in contaminated and aggressive underground environments.

BluCem HB55 is our sprayable cementitious shotcrete solution which is used for both the reinstatement of existing infrastructure and construction of new structures. HB55 has extremely low permeability and high resistance to sulphate and chemical attack, making it suitable for long term durability in underground environments.

We also recently introduced BluCem ZeoGlass. Developed using a blend of carefully selected recycled glass aggregates combined with our cementitious material BluCem ZeoGlass is a very dense, high build inorganic polymer structural mortar. The selected aggregates are custom graded by Bluey Technologies to create maximum interlocking during dry spraying. This builds depths of several hundred millimetres in one pass, creating a strong and highly resistant structural repair mortar.

Thin Spray Liners
Thin spray liners are highly useful to permanently consolidate and seal brickwork, concrete structures and rock excavations from gas and/or water transmission.

BluSeal TF05 is designed to form a flexible and durable membrane suitable for sealing and consolidating shotcrete, concrete linings, rock excavations and brickwork. BluSeal TF05 is used for lining bored and driven tunnels, cut and cover tunnels, cross passages, shafts and underground structures. BluSeal TF05 can be applied in a range of thicknesses for various performance applications. The membrane liner is applied to structures to prevent water inflow and provide asset protection.
