Root Barriers / Moisture Barriers

Learn about root barriers / moisture barriers and see how they can be used for foundations.

WHAT IS A MOISTURE BARRIER?

Moisture barriers are vertical layers of plastic that are buried in the ground.  As water flows up against a moisture barrier, it is stopped and prevented from getting under a home. Click here for foundation drainage solutions information >>

 

WHAT IS A ROOT BARRIER?

Root barriers can be solid objects, sheets of material, zones of chemically treated soil (typically, the chemicals come in the form of pellets that are attached to a fabric) or any other barrier that keeps roots from growing into areas where they are not wanted.

 

WHAT TYPE OF ROOT BARRIER DOES ADVANCED USED?

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?

Root barriers that are made of concrete, or plastic will last indefinitely.  Chemical root barriers have lives that range from 5 years upwards.  The life of a chemical barrier is strongly influenced by the amount of water that falls on or flows through the treated soil.

 

HOW ARE THEY INSTALLED?

Root barriers are installed by:

  1. digging a trench,
  2. laying the barrier material in the trench, and
  3. refilling the trench.

For concrete barriers, the concrete is simply poured into the trench.

WHAT DO THEY COST?

Root barriers should be at least 3 feet deep.  If they do not go at least one foot deeper than the side of your foundation, they will do no good.  For a standard 3 foot root barrier, the cost is typically around $65.00 per foot with a $1,000 minimum.  The cost may be higher or lower, depending on the types of trees that are present and how close the trees are to the barrier.

 

IS THERE A COST ADVANTAGE COMPARED TO FOUNDATION REPAIR?

Absolutely!  The minimum price for foundation repairs is $3,000.  The average residential foundation repair costs about $7,500.  Root barriers are cheaper and less disruptive to install than foundation repairs.

I can't too highly recommend this company. I had work done of my foundation by another company several years ago. That work did not resolve the problem, and that company did not fix. Advanced was recommended to me by mother, who said they were the best in the business. I agree! They were polite, professional, charged reasonable prices, and did excellent work. They also have a strong guarantee that is backed by a trust. I can't imagine why you'd use any other company.read more

Advanced Foundation repair is the only way to go! The engineer, Eric was kind, helpful and informative! The crew under Haynard's watch was unbelievably considerate. The crew was in and out of our house for 5 days. Everyone of them were happy even in the 90 degree weather. They work hard and were very polite. If you saw my house now you would never even know they were here. They cleaned up every night and on the last day it looked like new! Very thankful to have been able to work with them.read more

Advanced recently performed our foundation repair and did a fantastic job! The job took four days and throughout the process, the workers were on time each day, were kind and courteous. They left our house clean each day and took great care in making my wife and newborn comfortable during the repair. They came back out to make adjustments, as was expected, and I am more than pleased with the results. Thanks to Juan Martinez, Miguel Mata and Ernesto Alvarato for doing everything I requested. I highly recommend Advanced Foundation Repair, they know what they are doing.read more
