"Where Science Meets the Earth"

Our Story

Over 12 years ago and out of necessity, Grant Lewis Gravel Locks CEO and innovator, started researching the many issues contractors are faced with and realised that there was a necessity for an alternative to the traditional methods of construction that had been around for many years. 


Out of this research Flexi-C-Ment Gravel Lock’s flagship polymer modified additive to cementitious stabilizing was born shortly followed by HSC a non-hydraulic setting Sorel Cement, RDC a remarkable Road Dust Control and CSC for dust capping, short term dust suppression and hydroseeding.  A few years following on from this range, XTM – Xtreme a top down stabilizer and dust suppressant as well as PHF a coldmix pothole fill were added.  These are all exceptional products that have many excellent features and benefits for stabilization (long and short term) road repair, dust suppression and road maintenance.


After many years of intensive testing, both in the laboratory and in the ground, the results have provided a solid platform to conquer the challenges presented culminating in this specialised range of high tech products for the Civil Construction and Roading market place.  Gravel Lock wants to change the way that roads are built and give Customers a choice to use resources that may be considered not viable or marginal or, just use what they have on site. 


Achieving results like unsealed roads taking 300 logging trucks a day with no extensive maintenance for 36 months; dust free pavements guaranteed to last at least 6 months and more like the summer season to pavements seeing a year out with no complaints, references like “the best commercially available” from industry specialists we know we have it right!


Through hard work and determination Gravel Lock now proudly supplies products and services to the global marketplace with Sales Agents and or Distributors in Australia, Indonesia, Germany, Dubai, The Pacific Islands and of course New Zealand.
