Shear Lock® – Engineered Slope Retention System

The Shear Lock Engineered Slope Retention System is an innovative and cost effective way to protect slopes from potential landslides and to repair existing landslides.

ABOUT

The Shear Lock® Engineered Slope Retention System is an innovative and cost effective way to protect slopes from potential landslides and to repair existing landslides.

Shear Lock uses tried and true engineering principles combined with the patented* Shear Lock Piles to quickly and efficiently retain unstable material and ‘lock’ the potential shear failure plane.

Many areas in New Zealand especially around road and rail infrastructure are marked by steep and unstable slopes causing landslides to block the road or rail network during frequent storm events. With the Shear Lock system, the slipped soil can be pushed back onto the slope and compacted into place, then stabilised by installing Shear Lock Piles in a predetermined grid pattern.

BENEFITS AND FEATURES 

  • Prevents costly and time consuming cartage of slip material away from site
  • Fast design and execution due to extensive research of typical designs
  • Can be engineered to meet specific site conditions 
  • Uses readily available and pre certified Shear Lock piles which are used as the basis for the Shear Lock design charts
  • Backed up by extensive Engineering research and computer modelling 
  • Can be used for repairing existing failures or stabilising known potential slides
  • Peace of mind for road network supervisors and rail area managers that key sites have been stabilised

TCDC Slip Repair Tuateawa Coast Road – Platipus® Anchored Reinforced Grid Solutions (ARGS)

10 Nov 2015

The geotech engineers from Opus International chose the Platipus® (ARGS) System for this repair. Part of the reasons it was chosen included the tested and documented performance of the Pyramat® HPTRM when used to preventing surface erosion, while giving a larger tensile strength than that of steel mesh. The high tensile strength and extremely high resistance to UV along with the unique X3® fibres of the Pyramat® HPTRM was needed in this tough seaside environment where the matting will be exposed to salt spray and extended UV exposure.
