The root tips offer no resistance against obstacles, whether a small rock, a piece of wood, a foundation wall and even a hard and compacted soil. The elongation of the roots will follow the direction where the ground condition is ideal.<\/p>

When roots encounter crushed stones, under the parking lot or street, or when they reach the reinforcement of pavement or any other barrier, they grow in another direction.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

For the same reasons, a parking lot that has a properly structured foundation under the asphalt, or the paving stones or slabs, will create a barrier against the roots. When construction standards are respected and soil is stabilized to prevent the movements of freeze-thaw cracks, no root damage is possible. If after several years and for different reasons (soil compaction, freeze-thaw, water infiltration or other), the construction deteriorates enough for a root to infiltrate, cut the root and resurface the parking lot.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

Research shows that the presence of roots in pipes is due to dislocation or loss of a seal in the connecting joints. This opening permits root infiltration.<\/p>

The opportunist roots take advantage of water availability, nutrients and oxygen. As long as the conduits are not fixed and impermeable, roots will grow, ramify and colonize the place.<\/p>

The joint opening is due to a set of defect factors, often combined with age, such as the type of pipe used, the mechanical motion of the soil (packing or freeze-thaw), and the quality of the bedding or of the foundation when installing pipes, the type of filling and the type of connecting joints between the pipes.<\/p>

Roots take advantage of a weakness or of a default existing in the conduits. Repair of underground pipes solves the problem permanently. (People used to use concrete piping (or clay) of a length of 4 feet; and today, they use PVC plastic pipes or fibreglass FRP in longer sections.)<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
