Caring For Your Porous Pave Surface
Porous Pave is a unique material when compared to traditional surfacing materials such as Porous Concrete and Porous Asphalt. Since Porous Pave is made from recycled rubber granules and aggregate it remains flexible in nature unlike the previously mentioned products which have a “fixed void” once they are cured. A “fixed void” is one that is hardened allowing pockets where sediment can become trapped and difficult to clean.
Porous Pave, because it is flexible, moves when walked on or driven on. This movement helps to work the fine particles thru the material and into the substrate. Porous Pave also has a much large void space than other similar materials. Porous Pave has a typical void space of 29% allowing fines to pass through or to be vacuumed out quite easy.
Porous Pave was made for Canadian winters. Snow, ice, extreme cold and constant freeze/thaw are not an issue for Porous Pave. Both the recycled tire fragments and the proprietary binder remain flexible even under extremely cold conditions. This means your Porous Pave will not crack or develop potholes under extreme temperature changes and retains its strength even over multiple freeze/thaw cycles acting like one big expansion joint.
Snow & Ice Removal
Traditional snow and ice removal methods work with Porous Pave and are safe to use. None of these methods will damage the permeable surface. Ice & Snow can be removed safely with any shovel or snowblower. Snow removal may be done by snow plow, provided the plow is equipped with a shoe to avoid damage. The plow shoes keep the plow blade slightly above the surface. We recommend homeowners ask plow companies to back drag driveways to prevent any damage as well.
Salt is safe to use on your Porous Pave driveway. One of the advantages of a permeable driveway is that it makes snow and ice management easier. When the snow melts, water will go through the Porous Pave instead of staying on the surface. You won’t have to worry about water accumulating on your driveway and freezing again.
A Porous Pave driveway won’t eliminate ice completely (particularly in large ice events), but it will prevent melted snow from freezing again in cold temperatures by letting water seep through. You will be less likely to end up with large patches of ice on your driveway.
Customers report using minimal salt on their Porous Pave parking and walking surfaces. This helps not only your budget but also the environment.
We do not recommend using sand on Porous Pave. This will reduce the porosity of the product over time.
Surface Overcoating (suggested at year 5 for driveways)
Why overcoat? Over time, in heavily used areas, the surface of any porous pavement can show signs of wear. Proper maintenance will certainly prolong the life of Porous Pave. Applying a top coat of binder will restore the surface to “like new” condition.
The surface must be clean clean (blown/swept). Make sure all surface debris (leaves, stones, sticks, etc) are removed before applying the binder.
The binder top coat will be done by your local installer. Please contact your installer to get a quote.
In the event that Porous Pave material becomes clogged with silt or sand one of two methods may be employed:
- Large amounts of water can be applied at low pressure to wash the fines thru the Porous Pave into the sub base material.
- A common shop vac can be used for smaller areas up to a street sweeper for large areas to extract the fines.
Testing has shown that the vacuum method can remove not only the sediment in the Porous Pave but actually can remove fines from the sub base as well. Since repeated washing of sediment into the sub base can cause it to become plugged over time, it is recommended that method #2 is used consistently or at least periodically in conjunction with method #1 to prevent build up in the sub base.
Other common maintenance include regularly blowing leaves, sticks, grass clippings and other debris from the surface of the Porous Pave. This will help prevent breakdown of this debris preventing it from becoming trapped within the Porous Pavement. This is most commonly done by traditional leaf blower type equipment.
Porous Pave that is installed adjacent to gravel drives or areas where stones will likely be carried onto the surface of the Porous Pave should have regular cleaning. This will prevent buildup of the aggregate which could cause excessive and premature wear on the surface of the Porous Pave from vehicle tires if not removed.
Regular inspection and maintenance of the Porous Pave installations will help in prolonging both the porosity and the longevity of the installation.
Porous Pave in Canada
We started Porous Pave in Canada because we knew there was a better way. We weren’t happy that our asphalt driveway was full of cracks, and concrete seemed to cause more drainage. Learn More...
