Below-grade work is rarely visible in a completed home, but it plays a critical role in the long-term performance of the foundation. Our project partner, Ultimate Homes USA, recently shared this update from Aria Isle in The Woodlands, Texas:

Foundation work at Aria Isle, The Woodlands:
French drain and waterproofing system now complete.

Here’s what “high quality, high protection” looks like below grade on this build:

Conventional 24" concrete slab paired with ICF stem walls, then a five-layer waterproofing system anchored by DELTA®-DRAIN 6000 HI-X. A geotextile membrane wraps the perforated drain pipe as a filter, gravel is placed with a CAS Slinger for clean, consistent coverage, and the backfill — compacted lean clay — is finished with a smart remote-controlled trench roller from Third Coast Equipment.

None of this is visible once the home is finished. But it’s exactly what keeps a foundation dry and stable for decades rather than years. Getting the drainage plane right the first time is cheaper, faster, and far less disruptive than fixing water intrusion after the fact.

Proud of the crew’s attention to detail on this one.

This project update illustrates why foundation protection must be treated as a complete system rather than a single waterproofing product. The drainage, filtration, gravel placement, waterproofing, and backfill operations all have to be coordinated before the foundation disappears below grade.
