GRAVEL STABILIZATION SYSTEMS use plastic grids or similar materials to
stabilize gravel, preventing erosion while allowing water infiltration. These
systems offer excellent load distribution, reducing compaction of the underlying
soil and enhancing permeability. Gravel grids can also reduce maintenance
costs by preventing ruts, potholes, and migration of gravel. Additionally, many
systems are made from recycled materials, providing an environmentally friendly
stormwater management solution while maintaining a natural aesthetic.
Applications:
Best suited for rural or semi-urban applications, such as park trails, conservation
areas, and low-traffic roads, gravel stabilization systems offer a natural solution
for stormwater management in less urbanized areas.
Example:
In Quebec, stabilized gravel systems play a crucial role in conservation parks by
combining effective stormwater management with the preservation of natural
aesthetics and ecological integrity. These systems use plastic grids, honeycomb
structures, or geotextile underlays to reinforce gravel pathways and surfaces,
ensuring stability and durability even under foot or vehicle traffic.
The design of these systems minimizes the displacement of gravel, reducing
maintenance needs and preventing erosion that could otherwise damage
surrounding ecosystems. By allowing water to infiltrate through the stabilized
surface, these systems help prevent surface runoff, which can carry pollutants
into nearby waterways. This infiltration supports groundwater recharge, crucial for
maintaining the natural water cycle and sustaining local aquifers.

Why it’s a good option for Canadian climates:
Gravel stabilization systems perform well in rural environments and are
adaptable to both cold and temperate climates. Regular maintenance is
essential to ensure long-term performance, especially during periods of heavy
snow or rainfall.
Plastic grids help keep gravel in place, preventing
erosion while allowing water in昀椀ltration.

Final thoughts
Permeable surfaces are a smart, sustainable
solution for managing stormwater, combining
practicality with environmental care. By using
innovative materials and designs, Canadian
municipalities can tackle urban flooding, ease
the strain on stormwater systems, and create
greener, more resilient cities.
