Xperiment Posted July 16, 2018 The thing about roots is they can be soft and fleshy yet still exert incredible force. Have you ever seen an abandoned road? Within a few years the bitumen is torn up by weeds and wattle trees growing through it. The seeds germinate and the roots find a crack and slowly swell with water and life. Similarly, a city footpath with 40 year old fig trees tossing the slabs of concrete aside in slow motion. There's a lot of power there - plant wisely with the mature size of the plant in mind 1 Share this post Link to post Share on other sites

waterboy 2.0 Posted September 16, 2018 I missed this, but on foundations, trees and soil.... It's not just physical root force on foundations, it's the change In moisture status, which can have parts of the foundation move differently and then cracking the foundation, or exert the movement into the house frame(cracking internal walls, jamming doors ect). If it's a "reactive" clay this action is more prominent, no probs in sand (doesn't shrink/crack or swell with changing water status) . Plants can draw out the water in their zone of roots and change the soil state if a reactive soil. Also some pour water into a drying soil and cause the differential movement. In Australia that's H1, H2 and E Foundation classifications(high reactive clay content, close to the surface). Share this post Link to post Share on other sites
