Crawlspace Waterproofing & Structural Reinforcement

A homeowner reached out to Smouse Bros Foundation Repair & Waterproofing after another trade professional working in their crawlspace alerted them to significant moisture issues. Though a vapor barrier had been previously installed by a pest control company, it had become brittle, compromised, and submerged by pooling water across the entire backside of the home’s crawlspace. While the damage was not yet extensive, the situation posed risks of HVAC damage, structural issues, and major complications during future home sales. Additionally, Smouse Bros identified outdated softwood shims beneath the home’s structural support beams, which could lead to uneven floors, sticking doors, or drywall cracking.

The Solution

After a thorough inspection, Smouse Bros developed a comprehensive waterproofing and structural reinforcement plan:

Standard Crawlspace Sump Pump System: Installed a 24-gallon sump basin and 1/3 HP Wayne sump pump positioned at the crawlspace’s lowest point. The system effectively relieves hydrostatic pressure, directing excess water through the foundation to an exterior yard pop-up.

Interior French Drain System: Installed 4-inch perforated drain tiles around the interior perimeter of the crawlspace, surrounded by clean gravel to ensure proper drainage and prevent trench collapse.

Vapor Barrier Replacement: Completely removed the compromised barrier and replaced it with a robust 12-mil white woven vapor barrier, including dimple board drain matting beneath. The barrier was securely fastened above the footer with nails, avoiding adhesives that degrade over time. Crawlspace vents were left unsealed intentionally, and no dehumidifier was needed.

Structural Re-shimming: Hydraulically lifted main support beams to remove deteriorating softwood shims, replacing them with durable oak flats and wedges. Post-installation, Smouse Bros verified that all interior doors functioned correctly to ensure structural integrity and homeowner satisfaction.

The Result

With these targeted improvements, the crawlspace is now thoroughly waterproofed and structurally sound. The homeowner enjoys peace of mind knowing their property is protected against moisture-related damage, potential mold growth, and future resale issues. The proactive approach taken by Smouse Bros has safeguarded both the structural integrity and value of the home.
