Advanced Foundation Repair’s, recently released an educational video and white paper which walks homeowners through how exterior foundation waterproofing membrane moisture barriers can be including in foundation drainage systems. “The purpose of the moisture barrier is to keep ground water from moving under a foundation.” states Fred Marshall, owner of Advanced Foundation Repair.

What is a Moisture Barrier?

Moisture barriers are exactly that. They hinder or stop moisture from moving from one place to another. Used through-out construction, moisture barriers come in various forms: moisture barrier film, moisture barrier plastic, or concrete moisture barrier.

Concrete Vapor Barriers

Don’t confuse a foundation waterproofing membrane moisture barrier with concrete vapor barriers which are installed when pouring a foundation. They help prevent damp cold and clammy concrete floors by stopping water vapor from moving through a concrete floor as well as hindering moisture from deteriorating the concrete and from damaging sealers and overlays. Place vapor barriers down before pouring the slab.

Exterior Foundation Waterproofing Membranes Moisture Barriers

For concrete slab foundations, bury foundation waterproofing membranes moisture barriers’ vertical layers of plastic in the ground around the perimeter of the foundation. Install foundation waterproofing moisture barriers after finishing concrete slab foundation installations.

Exterior foundation waterproofing membrane stop water as it flows up against it, thus preventing water from getting under a home. The purpose of the membrane is to keep ground water from moving under a foundation and to help maintain moisture levels in and around a foundation.

Moist Soil is Good

Keeping the right amount of water in the soil is important for foundation maintenance.

Under seal concrete slab membraneWith too little water the soils shrink and the foundation goes down but with too much water the soil expands and pushes the foundation up. To help control situations where too much water is entering the soil, engineers sometimes call for the construction of a foundation waterproofing membrane moisture barrier.

Exterior Foundation Waterproofing Membrane Moisture Barrier InstallationWhile installing foundation waterproofing membranes is fairly basic, they are exceedingly labor intensive. Attention to detail is critical to ensure the moisture barrier does not have any tears or gaps. Foundation membranes are most commonly a polyethylene membrane. Check with a local hardware store for supplies then determine the depth of seasonal moisture. Dig a trench around the foundation then install the membranes so that they are below the depth of seasonal moisture. This could be as far down as ten to twelve feet. Many have an adhesive system that attaches to the top of the foundation. Back fill the trench. Moisture Barrier

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
