Erosion Control & Dust Capping

PROJECT- 2014

This 28km long 4 lane wide highway was one of the largest projects being constructed in New Zealand at the time.  The highway was constructed over weak subgrades so it needed to be preloaded with millions of tons of sand and soil requiring strict environmental controls. Gravel Lock was proud to be a key supplier of CSC dust capping and erosion control in the Tauranga Eastern Link project.

Dubai Sand Stabilizing

PROJECT – November 2018
The GCC countries (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates) depend heavily on the outside world for the supply of most of their aggregates due to lack of resources.  Being able to stabilize insitu granular sand is a major breakthrough for these countries.  Flexi-C-Ment was used in Dubai to stabilize a pull off lane (shoulder) in an industrial roadway and also a loading construction bay used for the sale of aggregate.

Give Way Intersection

PROJECT- 2018

This rest area is situated just off a very busy highway and experiences extreme amounts of through traffic on a daily basis.  The Give Way area is prone to unravelling and potholing which causes road users to experience a negative experience when leaving this complex.  Gravel Lock put down a trial of PHF Coldmix Pothole Fill, in the middle of winter, next to traditional fill for the owner to assess the viability and longevity of the product. The PHF is still strong and well bound after 2 years.

Car Park Entrance

PROJECT- 2018

 

This busy entrance/exit way of a shopping complex was experiencing reoccurring potholes.  Traditional pothole fill  was not lasting and falling out within weeks of being installed.  Gravel Lock undertook works with the Owner of Big Tomato Complex to install PHF to the existing potholes in the entrance way.  This busy shopping centre experiences hundreds of car movements each day pulling in from an arterial thoroughfare which was becoming dangerous for the customers.
