How foundation repairs relate to residential landscape?
Over the years, homeowners have heard many conflicting stories about how landscaping can cause foundation problems and induce foundation repairs.
Of course the benefit of landscaping are many and easily outweigh the potential negatives, specially if the landscaping is done with a correct plan.

When installing a root barrier, homeowners should place it as far away as possible from the tree in order to reduce the damage to the tree. The barrier should at least 4 feet deep and be made of a material capable of blocking the roots, typically reinforced concrete or corrugated hard plastic.
