Drought Defense System – foundation watering protects your home from the damaging effects of drought

olshan drought defense systemThe risk of foundation damage threatens Texas homes as drought conditions drag on. As we face yet another season of extended dry weather, now is a good time for Texas homeowners to revisit the importance of foundation watering as a common-sense protective measure.

How do drought conditions affect foundations?

A foundation is only as good as the soil that supports it. A reputable homebuilder will take several important precautions before and during construction to make sure that the foundation stays in alignment with full load-bearing capacity for the life of the home above it.

  • Confirm the surrounding soil type and composition
  • Confirm the correct soil depth for piers and support enhancements
  • Prepare the site with proper soil compaction and rough grading
  • Account for local ground water conditions in foundation design and construction
  • Plan fine grading that draws excessive water away from the completed home

There’s a “Goldilocks” factor at work in the partnership between your home’s foundation and the soil holding it up. Too much moisture leads to erosion and causes parts of your foundation to sink or drift out of alignment. Too little moisture causes the surrounding soil to contract and pull away, compromising the foundation’s ability to support the weight above it.

Extended drought conditions increase the odds that dry, shrinking soil will pull away from below-grade concrete or masonry and attack the integrity of your foundation. The ideal is just enough moisture to keep the soil around your foundation properly compacted with even contact (and resistance) all the way around the entire structure.

What is foundation watering and how does it work?

All homes tend to settle naturally over time as building materials age and interact with the environment. Ideally the settling is minimal and occurs evenly, but structural damage can start (and worsen over time) if erosion leaves parts of your foundation unsupported.

Fortunately for Texas homeowners, foundation watering is a protective measure that can help maintain moderate and consistent soil moisture. If you’re a DIY enthusiast with less severe issues and catch problems before the serious foundation damage begins, this is something you might be able to manage yourself, with a simple homemade solution that includes a soaker hose.

For more serious structural problems related to drought, you’ll want a more comprehensive and long-term solution.

Olshan’s Drought Defense – Foundation Watering System – Maintain Stable Soil Conditions Underneath Your Home

Don’t let drought conditions ruin your home’s foundation. Olshan’s innovative Foundation Watering System can be installed to protect and monitor the soil underneath your home.

For moderate-to-extreme cases, especially in extended drought conditions like we have in the Texas area, a DIY approach can be too time-consuming and less effective long-term. The good news is, Olshan’s Automated Foundation Watering System is designed to take the worry, hassle and guesswork out of foundation maintenance.

Paul Howland of Olshan Foundation Solutions in Houston, TX explains how the process works:

The first step is to dig a two-inch-wide trench around the outside of your foundation. The trench runs from 12 to 18 inches deep and sits about two feet out from the exterior walls. Next, we install an engineered water line with emitters at 12-inch intervals to maintain consistent moisture levels. Moisture sensors ensure optimal saturation and prevent water waste.

Unlike a simple soaker hose solution, Olshan’s Automated Watering System waters deep below your home’s foundation – where it’s needed most.

Keeping Your Home on Stable Ground

  • Deep Hydration. A dripline is installed inside the trench with moisture emitters. Moisture emitters are spaced every 12 inches to help maintain consistent moisture levels.​
  • System Protection. A freeze-resistant backflow preventer is installed to protect you and your system from outside elements. ​
  • Take Control. Easy-to-access controller is installed inside an access box, allowing you to maintain your watering plan effectively, throughout the seasons.​

    I wish you serviced Kansas. This is the only such service I have seen offered anywhere. We had a structural engineer come out to inspect our foundation due to drywall cracks and he said you can either spend $50,000 and pier the whole thing or just keep your soil properly moisturized . Easier said than done.
