What is a root barrier?


What type of root barrier does Advanced use?

Advanced installs root barriers made of a three layer plastic membrane.  The second and third layers give extra protection against penetration by roots and make the membrane tougher.  By using a tough plastic membrane that is water proof, Advanced’s root barriers have the added benefit of acting as moisture barriers.

Why use a root barrier to protect your foundation?

When roots get under your foundations, they can cause foundation damage by drying out the soil under your foundation and causing your foundation to settle.  Roots also break into pipes causing extensive plumbing damage. In this case broken pipes lead to over wet soils which will cause foundations to heave. Stop the problem before it starts. Installing root barriers will be cheaper than foundation repairs.  Just as brushing your teeth is cheaper than paying for fillings, root barriers will not prevent all problems but they will stop most of them.

How long do root barriers last?
