Two decades of experience working on numerous energy projects have given us in-depth knowledge + knowhow, which enables us to deliver specialised construction products to our industry partners.
We offer a variety of engineered cementitious and ground support solutions to contractors across the country, ensuring the safety and efficiency of these high priority assets.
In 2011, we introduced BluGeo GRP60, a glass-fibre reinforced polymer bar which is non-conductive and has an extremely high load-carrying capacity. At ¼ the weight of steel, the bars offer designers and specifiers an innovative solution to traditional electrically conductive ground anchoring and soil nailing.
Power and energy cables can produce high thermal heats, due to the voltage passing through them. When grouting these conduits, a product must be selected which remains cool during placement (to avoid damage to the conduit and cables) and allows the grout to effectively transmit the heat of the cables during its service life.
Being fully shrinkage compensated and low exothermic heat generating makes BluCem LH60 suitable for a range of deep pour applications where low heat is necessary to protect surrounding services and minimise thermal shrinkage.
BluCem LH60 has a thermal resistivity (TR) less than 0.9 and low exothermic heat to avoid heat damage to the conduits during curing. LH60 can also be supplied in 1200kg bulk bags which allow 5m3 agitators to supply the product rather than conventional concrete pumps.
The turbines require deep ground anchors to support the loads generated by the long lever arm of the tower and the dynamics of its moving blades. The connection of these anchors to the rock is then consolidated with the use of a high strength grout which protects the steel cables from corrosion, hydrogen embrittlement and provides a 100-year design life.
BluCem HS120 is our high strength grout solution. The grout is a highly fluid, volumetrically stable, Class-C grout which has both early and long-term shrinkage compensating additives. This ensures that expansion is staged to compensate shrinkage both in the plastic and drying states so that the grout will far surpass the design life of the wind turbine.
Ground anchors are essentially restraining devices used in many different types of construction from piles to abutments and foundations. 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.
