Ready for Pervious Pour

Northside College Prep. High School-
The concrete ribbon path that begins at the greenhouse,

winds back to the BBQ pit

turning north following the river is all set for a pervious pour……….

Pervious - What is it?
A unique porous concrete pavement that allows water and air to pass through tiny holes and filter into the soil below, think of it as a structured sod because it acts as a filter like grass. The mix is a slurry of gravel and concrete poured from a conventional cement truck. It is often used for sidewalks, driveways and parking lots.

This material provides a sustainable, economical and long lasting green building material for our world. It is comprised of local materials, a storm-water solution, helps decrease urban heat islands with it’s light color and has winter benefits. Water, snow and ice do not puddle or run-off this pavement, the water flows through and the voids allow warm air from the ground to rise naturally melting the snow. The gain in winter is less snow removal and salting with the pervious not cracking like other pavements which means less costs in the long run to repair or replace surfaces.


can be used for many other applications

Thursday August 9 Ozinga Brothers arrived at Northside College Prep to teach and demonstrate a pervious pour. The ribbon path is now complete to the celestial garden and many people benefited from the day. Interns joined in with the pour, moving wheelbarrows full of mix and allowed to become certified pervious concrete installers by taking an exam.

Thank-you Brian,Ozinga and everyone else that helped make the day a success
