[CANUFNET] sidewalk materials suitable for a winter city

[Reny, Robert]

Hi Martha,

We are dealing with a similar scenario where a new sidewalk is planned to be built adjacent to a 100 year old Heritage Oak tree. To address this conflict, we plan to build a root bridge over the critical root zone of the oak tree. The root bridge is built using 1 meter long ground screws spaced along the perimeter of the sidewalk, a metal frame is then attached to the head of the screws and cantilevered over the roots. The frame supports any type of poured hard surfaces, we plan to use a porous concrete.

While our winters are certainly not as cold as your area, I'm not sure how this system would react to freezing and thawing conditions. I would recommend contacting our representative to find out more.

Subject: [CANUFNET] sidewalk materials suitable for a winter city

We are looking for alternative sidewalk treatments adjacent to mature American elms for a new apartment development in an older neighbourhood near our city center (Osborne Village). The proposed sidewalk is within 2 m of the trees where there has never been a sidewalk previously.

We are looking for a treatment other than concrete or pavers. Has anyone had experience with rubber sidewalks or other materials / methods in conditions similar to ours - freeze/thaw cycles, clay soils, very active winter road maintenance program (de-icing salt and snow clearing equipment on sidewalks)? The sidewalk would have to withstand sidewalk snow clearing equipment and meet accessibility design standards.

Any information would be greatly appreciated!

Thanks,
