Benefits versus steel BENEFITS VERSUS STEEL. Lighter one man operation in most cases More economical and faster installation than steel Eliminates site safety issues associated with steel Eliminates corrosion for long term durability No need for Double Corrosion Protection (DCP) No contribution to stray currents No risk of damaged sheathing or galvanising BluGeo POWERTHREAD K60. Grout BluGeo Powerthread K60. Spacer STEEL SOIL NAIL WITH DCP. Grout Steel Reinforcing Bar Spacer HDPE Sheathing BluGeo GRP Ground Systems 5.
4 BluGeo GRP Ground Systems PRODUCT FEATURES & BENEFITS. NON CONDUCTIVE. BluGeo Powerthread is a non-conductive element Resistance >1000k /cm (immeasurable). Eliminates stray current corrosion Reduces maintenance costs for Rail Authorities RELIABILITY. No reliance on galvanising or sheathing for corrosion protection. No risk of damage to complex DCP Systems during installation ensuring reliable 100 year design life. DURABILITY. BluGeo GRP Ground system bars have durability exceeding 100 year life expectations. The bars are resistant against acid attack as well as against alkaline attack and provide long service life in aggressive soil conditions. LIGHT WEIGHT. Due to the low density of glass and resin, BluGeo GRP.
5 Ground system bars are 1/4 the weight of steel. The low weight facilitates handling and reduces risk of injury to installers where manual handling is necessary. This feature minimises the transportation cost and can reduce dead loads on structures. HIGH TENSILE SHEAR STRENGTH. BluGeo GRP Ground system bar has double the tensile strength of normal steel and high shear strength. SAFE INSTALLATION. 12m bar can be lifted safely by 1 person Simple installation operation IMPROVED SITE HANDLING. Less crane movements and machinery required on site Reduces risk of site transport, loading and unloading incidents No need to protect from weather during storage - non corrosive and UV resistant 6 Bluey Technologies BluGeo GRP Ground Systems PRODUCT FEATURES & BENEFITS.
6 CUTTABILITY. Much safer cutting without need for high speed disc or oxy-acetylene equipment Allows easy future excavation for widening works - whole of life cost Continuous thread profile allows the bar to be trimmed on site QUALITY OF INSTALLATION. No reliance on galvanising or sheathing for corrosion protection No risk of damage to complex DCP system during installation No minimum cover requirements in accordance with AS3600. FAST EASY GROUTING. BluGeo Powerthread is a single grouting operation with no sheathing AS3600. Full encapsulation and engagement of the bar with approved grout RMS approved grout BluCem HS200G allows pull testing after 24hrs ECONOMICAL. No sheathing is required, allowing single stage grouting & fast, easy install.

EXAMPLES OF FACING Systems USED IN A SOIL NAIL STRUCTURE. HARD FACING SOFT FACING WITHOUT FACINGS. The combination of soil nails and The primary function of soft facing is Nailing in case of critically inclined facing has to fulfil the function of erosion control and protection against sliding surfaces ( rock strata with stabilising the slope between the nails, surface ravelling. In many cases, the soft reduced shear resistance), however and shall therefore be dimensioned facing has to reinforce the vegetation with a stable surface.
