Advanced Foundation Repair, a Texas Foundation Repair company, recently released an educational video and white paper combination walking homeowners through how foundation waterproofing membrane moisture barriers can be included in foundation drainage systems. “The purpose of the foundation waterproofing membrane 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 throughout construction, moisture barriers come in various forms: moisture barrier film, moisture barrier plastic, or concrete moisture barrier.
Don’t confuse a foundation waterproofing membrane moisture barrier with concrete vapor barriers. Concrete vapor barriers are installed when a foundation is poured. They are there to prevent a damp, cold and clammy concrete floor. By stopping water vapor from moving through a concrete floor, vapor barriers help prevent moisture from deteriorating the concrete and from damaging sealers and overlays. Vapor barriers are placed down before the slab is poured.
For concrete slab foundations, foundation waterproofing membranes moisture barriers are vertical layers of plastic that are buried in the ground around the perimeter of the foundation. They can be installed after a concrete slab foundation has been completed. As water flows up against an exterior foundation waterproofing membrane, it is stopped and prevented 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.
Keeping the right amount of water in the soil is important for foundation maintenance. With too little water the soil shrinks and the foundation goes down. 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.
While 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. Determine the depth of seasonal moisture. Dig a trench around the foundation. 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.
