CORE Gravel™ Foundations

CORE Gravel™ Foundations

Gravel Driveway, Path and Parking Stabilization  

CORE Gravel™ is a gravel stabilizing system that consists of a foundation of connected honeycomb-celled panels with a geotextile backing. Once filled with gravel this system is ideal for public spaces, vehicle or pedestrian traffic with no compromise in strength and durability. This eco-friendly system costs less than other parking systems, including asphalt, concrete and block pavers.

Permeable Gravel Surfaces that do not rut or move...

CORE Gravel™ solves the problems associated with loose gravel; sinking, migrating and forming ruts. This is a proven solution for hassle-free gravel paving for all types of vehicle or pedestrian traffic with no compromise in strength and durability. The underside incorporates a durable geotextile which is heat welded to each cell, allowing water to drain easily while preventing weed growth. All panel edges have an interlocking system that makes for easy installation, even on steep grades.

Made with either 100% recycled PP (polypropylene, black or green) or recyclable PP material (white or gray), our proprietary manufacturing process provides a rigid honeycomb core design that holds its uniform hexagon shape while providing maximum load bearing. When filled with gravel the product is practically invisible, making for attractive driveways, pathways and patio installations. This porous and eco-friendly surface allows for storm water to permeate into the soil, dramatically reducing runoff problems.

CORE Gravel™ is an excellent gravel stabilizing system. The video gives you an idea of how strong the product is based on the use of this hexagon, closed cell system. (Video courtesy of COREGravelUK, medium duty permeable paver featured.)

All CORE Gravel™ grids are available in white virgin polypropylene or black recycled polypropylene. Both options are virtually invisible when filled with gravel, even when using a light coloured aggregate.

CORE Gravel™ Applications

  • Public Spaces & Parks
  • Driveways 
  • Access Roads
  • Parking Lots
  • Camping Sites
  • Playgrounds
  • Bicycle Trails
  • Pathways
  • Sports Grounds
  • Golf Cart Paths
  • Landscaping
  • Patios

Why choose CORE Gravel over other products on the market?

All of our grids (grass or gravel) area closed cell system. This means that all of the cells are attached to the neighbouring cell with no open spaces. Open spaces means gravel can seep out and weight distribution is not even. Our system provides an even weight distribution and no opportunity for gravel to seep out, which translates to better use and minimal maintenance. A CORE gravel surface starts out flat, tidy and attractive.....and stays that way.

CORE Gravel Benefits

  • Gravel Stabilization - Get gravel to stay put, no ruts, no sinking, no problems.
  • Low Cost - Because the gravel won't move around you can use less, giving you a porous surface that costs less than concrete, asphalt or block pavers.
  • Superior Strength - Enhanced load bearing eliminates rutting, separating or sliding with vehicle traffic.
  • Reduce Base Gravel Layer - Gravel Equivalent Factor (GF) is 4"-6" for every 1" of our CORE Gravel grid height.
  • Weed Reduction - The geotextile backing underneath each panel prevents weed growth.
  • Green Solution - Environmentally friendly porous gravel paving allows the rain to drain over the entire surface.
  • SUDS Compliant - Because CORE Gravel is porous it is ideal for solutions requiring a Sustainable Drainage System.
  • ADA Compliant - Ideal for pedestrians, bicycles and wheelchair traffic.
  • Invisible - When filled the product is practically invisible, leaving you with a stunning surface that is easy to maintain.

CORE Gravel Product Features

  • All of our grids contain Carbon Black as a UV (ultra- violet light) inhibitor.
  • All of our grids are made by Injection Mold, the highest quality process available for creating rigid plastic products. Lower quality 2-part extrusion molded products that come in rolls and have non-continuous surfaces are not uniform and the plastic has the potential to separate with tire turning.
  • All of our CORE Gravel™ and CORE Grass™ grids have flexibility (resistance to fracture), tensile strength and maximum shearing load (thank the bees for these last 2).
  • All CORE Gravel™ grids come with a geotextile fabric heat-welded to the back of every single honeycomb cell. This saves time and money during installation.

NOTE: Our compression testing results are provided for EMPTY cells as well as filled. Variable fill material can skew compression testing results depending on the ‘hardness’ of the rock. So, when comparing different grid system, compare only the ‘empty’ cell compression test results for a true comparison of product durability.
