How To: Maintain a Pier and Beam Foundation

Maintaining a proper drainage system is crucial for keeping a pier and beam foundation strong. When moisture seeps under the foundation, it can cause damage over time. During dry seasons, the ground may become dry, but heavy rains can lead to water accumulating under the house. This can lead to problems such as rotting wood, mold, and termites. To prevent these issues, it is important to make sure that water does not accumulate or flow towards the foundation. Regular maintenance of the drainage system will help ensure that water is not trapped near your house.

Keeping your foundation in good condition for a long time requires controlling moisture levels, especially around the perimeter of your house. Interior support piers are particularly susceptible to moisture damage, as mud and moisture can cause them to sink, mold, and rot. Exterior sections of piers can also be affected in the same way.

In the past, the focus was on keeping the soil dry, but recent advancements in technology now allow for more precise measurement of moisture content in the air below your home. Properties located in areas with high humidity are at risk of high moisture content entering beneath the structure, which can lead to costly maintenance for the foundation. The latest technology involves completely sealing off the underside of the structure and installing dehumidifiers to remove excess moisture that enters the crawlspace. This “encapsulating” technique is the best way to properly maintain your pier and beam foundation home in the Houston area.

It’s essential not to overlook checking your gutters and downspouts. Make sure that the water from the gutters is not splashing directly onto the ground near the foundation. It’s advisable to direct the water at least six feet away from the house using downspout extenders.

Avoid having gardens too close to the house, and if they must be, ensure that effective drainage systems are in place. Keep in mind that materials like peat, mulch, or bark tend to retain more water than necessary, which can negatively impact the underground structure.

While post and beam construction provides many benefits, it’s crucial to pay attention to the underground support as even a small movement of a single pier can result in significant damage inside the house.

It’s important to regularly inspect your crawl space, ideally every six months, to check for any signs of movement. In a pier and beam structure, it’s easy to spot these signs as the posts and beams are visible. Look for any angling or shifting of the piers, as this indicates movement and potential structural damage to your house.

If you can keep the area under your home dry and free of termites, you should have a strong, healthy foundation for years to come.
