Heavy Duty Ground Grid (HDGG)

Pavers for parking and driveway: durable and really permeable

If you want to avoid floods and erosion, if you care about our rivers and lakes' cleanliness, if you want our cities to be cool and green, then using permeable pavers is inevitable. Due to their natural permeability, grass driveways and parking areas also reduce the need for expensive drainage systems.

Heavy Duty Ground Grid can endure heavy vehicles' intensive traffic while providing environmentally friendly and aesthetically attractive areas.

As you can see, our heavy-duty ground grids are considerably lighter than similar products made of pervious (permeable) concrete. The weight (19.8 lb/grid) allows lifting and installation by a single operator: you can handle the units during offloading without breakage. Their transportation is also easier: almost twice as many units of HDGG (1280 pieces) can be loaded onto a truck compared to a concrete product.

Lighter weight reduces the shipping cost as well as is kinder to the environment. One more benefit for the environment is the Hahn HDGG units are manufactured from 100% recycled plastic (that may otherwise go to waste) and are easily recyclable at the end of life.

Water does not soak into the plastic permeable pavers; they allow the water to flow through their macro holes. As a result, these pavers are completely safe during freeze-thaw cycles. More benefits in the table below.

With an interlocking stabilizing system, our grids are just the job for car parks, pull-offs, farmyards, or warehouses.

Prices, dimensions and weight of HDGG

One piece of HDGG costs $16.50+tax. 5% discount if you buy a skid (pallet) of HDGG. There are 135 grids on a pallet.

The measurements of HDGG are: 23.62" x 15.75" x 3.15", that is 60 x 40 x 8 cm or 1.97 ft x 1.31 ft. One Heavy-Duty Ground grid covers an area of 2.58 square feet.

Each grid weighs under 20 lb.

How many permeable pavers do you need?

If you want to calculate how many permeable pavers you need, then divide the area to cover (calculated in square feet) by the square footage of one paver. For example, to calculate the required number of HDGG, divide the area you want to pave (calculated in square feet) by 2.58 (the area of one Heavy-Duty Ground Grid in feet.)

The above is a rough estimation. Depending on the dimensions of the area to cover, you may need a few more grids. To calculate more precisely, you need to divide the length of your area (in meters) by 0.6 (the length of a grid in meters) and the width of your area (in meters) by 0.4 (the width of a grid in meters). Then multiply both results and get the number of grids you need. Do not forget to round the number of grids to a whole number.

You can do the same in feet, but it is more complicated, at least for me :) Divide the length of your area (in feet) by 1.97 (the length of a grid in feet) and the width of your area (in feet) by 1.31 (the width of a grid in feet). Then multiply both results and get the number of grids you need. Round the number of grids to a whole number.

Next time I will give you an example, but now I already want to go to bed...

A project with the use of HDGG (an example)

The picture below presents a living street project created in the city of Montreal using our HDGG. The product serves as an effective replacement for non-porous asphalt and concrete. Contact us to discuss the many benefits and opportunities of these products.

Permeable pavers instead of impermeable ones are already used in larger Canadian cities for parking and driving areas. Their usage has to become mandatory in the growing city of Barrie to decrease the runoff from spring melt and stormwater. It will decrease erosion, lake pollution, and expenses for stormwater ponds.
