[CANUFNET] sidewalks over tree roots

[Alex Satel - UFI]

Hi Jessika,

You might be interested in checking out Reducing Infrastructure Damage by Tree Roots (Costello, L.R. and K.S. Jones, 2003).

https://wwv.isa-arbor.com/store/product/107/

It might be a little dated now, but it reviews tree-based, infrastructure-based, and root zone-based strategies to address the issues you're concerned about. It also includes some cross-section details and case studies (mainly from California, unfortunately) for sidewalk bridging and ramping over roots.

Cheers,

Alex

Subject: [CANUFNET] sidewalks over tree roots

Hello,

Does anyone have experience with products or techniques (and photos?) used when replacing sidewalks where there are large, mature trees and substantial roots pushing up on existing sidewalk and there is no room to move the sidewalk? Any good products to assist with bridging over?

Many thanks!
Jessika
