[CANUFNET] Materials for base of trees

[Alison Bond]

Hi Taylor,

The Town of Collingwood (Ontario) has open tree pits surrounded by unit pavers in their downtown.  Last year they installed clear stone mixed with resin to tidy things up and provide for a better walking surface.  I think it may have been supplied by Green Blue Urban.  The idea is that it remains porous, while provide a firmer surface.

It’s tidy and seems to be wearing well, but I haven’t looked at it closely this spring.

(I can take pictures of it if you wish.)

Regards,
Alison

Hello Canufnet!

I am currently exploring alternative materials to place around the base of trees that are surrounded by sidewalks/paving. Typically we use crushed rock and compact it in order to minimize tripping hazards. We are interested in finding other options to mitigate some compaction and provide better drainage for the trees. We've experimented with mulch, but have encountered challenges with its longevity, particularly due to heavy rainfall in the Pacific Northwest.

I'm reaching out to inquire if anyone in the community has experience with using pour-in-place rubber or molded rubber as an alternative solution?

Any insights or recommendations on materials or techniques would be greatly appreciated.

Thanks in advance!
