Eco-friendly, durable and beau­ti­ful: por­ous pave­ment grows in pop­u­lar­ity


Since 2011, TAC Ot­tawa has spe­cial­ized in in­stalling spe­cialty pave­ments made from crushed stone as a more durable and beau­ti­ful al­ter­na­tive to asphalt or gravel. Now, founders Tay­lor Davis and Kyle Pittman have de­vel­oped a new prod­uct called PurePave, which ex­tends the al­ready im­pres­sive longevity of por­ous pave­ments, and makes it even eas­ier to push creative bound­aries in land­scape de­sign. They’ve es­sen­tially in­vented a new way to cre­ate jaw-drop­pingly beau­ti­ful drive­ways, walk­ways and pa­tios that are prac­ti­cally im­mune to the cracking and buck­ling caused by our harsh Cana­dian win­ters.

Vis­ually strik­ing and long-last­ing, PurePave lay­ers nat­u­ral crushed gran­ite, quartz or mar­ble with a spe­cially for­mu­lated UVand salt-re­sis­tant resin on top of a flex­i­ble base sta­bi­lizer made of re­cy­cled plas­tic.

Tiny air pock­ets in the per­me­able pave­ment and base al­low wa­ter to flow down 14 inches to drain nat­u­rally, in­stead of sit­ting on top or be­com­ing trapped within hair­line cracks. When deep win­ter hits, any freez­ing wa­ter has room to ex­pand so the pave­ment re­mains un­dam­aged. The flex­i­ble base pro­vides another layer of sta­bil­ity, so even if the ground be­neath shifts dur­ing a par­tic­u­larly vi­cious cy­cle of freeze and thaw, the sur­face holds steady and looks as good as ever.

Ac­cord­ing to Davis, it isn’t just the prac­ti­cal­ity of TAC Ot­tawa’s por­ous pave­ment that sells PurePave. It’s the stun­ning ef­fects de­sign­ers and land­scape ar­chi­tects can achieve by blend­ing dif­fer­ent types and tex­tures of stones.

The colour and tex­ture of the por­ous pave­ment de­pends on the kind of stones se­lected. Buy­ers can choose sub­tle shades of cream or grey mar­ble, spice it up with red and black gran­ite — or even add some nat­u­rally lu­mi­nes­cent glow­stone to cre­ate an ef­fect like a car­pet of shin­ing stars after the sun­set.

“We have tons of colours and we can blend the ag­gre­gates to cre­ate al­most any kind of tex­ture,” said Davis. “One of my favourites is called smoky black gran­ite. It’s pri­mar­ily black but has char­coal colours with speck­les of white and red, and the speck­les shim­mer in the light.”

Another pop­u­lar op­tion is to use stone pavers as a bor­der or to cre­ate geo­met­ric de­signs within a drive­way or patio.

The cost to in­stall a PurePave sys­tem is com­pa­ra­ble to higher-end ma­te­ri­als like in­ter­lock pavers or stamped con­crete, Davis said, and ranges in price de­pend­ing on the choice of stone and sur­face size.

Stud­ies on the longevity of por­ous pave­ments have found few if any cracking or pot­hole prob­lems even after 20 years, and still don’t need to be repaved.

“We re­ally dug into the re­search, and once it was re­vealed to us how strong and pow­er­ful this prod­uct was for our cli­mate, we re­al­ized it was a per­fect fit,” said Davis. ”It looks in­cred­i­ble, the ma­jor­ity of it is made of re­cy­cled ma­te­ri­als, and with our patented spray sys­tem, it can last for­ever.”
