Project Overview
A homeowner in Harbor, NY reached out to Zavza Seal due to multiple structural and water intrusion issues affecting their foundation, window wells, support posts, and sill plate. These issues posed significant risks to the property’s long-term stability and moisture control. The goal was to perform structural crack repair, improve basement waterproofing, and reinforce the support system of the home, all while preserving the surrounding finishes where possible.
The Problems
Upon inspection, our team identified four primary areas requiring remediation:
- Structural Crack in Foundation Wall
Cracks in the concrete threatened the structural integrity and waterproofing of the home. - Compromised Window Well Drainage
Poor drainage and aging window guards allowed moisture buildup and potential flooding. - Damaged Support Post
A weakened support post near the central beam posed a safety risk to the home’s structural load. - Water Intrusion at the Sill Plate
Water was seeping above the concrete foundation wall through the sill plate area, potentially leading to mold and wood rot.
Our Solutions
1. Structural Crack Stabilization
To address the foundation crack and prevent it from worsening, we implemented the following:
- Chased and ground the crack using a diamond blade to remove loose material.
- Installed Carbon Fiber Stitches embedded in structural epoxy. This restored tensile strength and halted further movement.
- Applied Basecrete waterproofing cement as a base layer.
- Installed 4.5 oz Basecrete fiberglass mesh to reinforce waterproofing.
- Applied a second layer of Basecrete cement to finalize the repair with long-term moisture protection.
2. Window Well Installation with Drainage
To eliminate water pooling near basement windows, we executed:
- Excavation to 3 feet depth around the window well.
- Installed a 4-inch gravel bed for proper drainage.
- Added a self-contained drainage system to move water away from the foundation.
- Installed galvanized window guards for safety and protection.
- Topped with a new plastic window well cover to shield from rain and debris.
3. Support Post Reinforcement
For improved structural support, we:
- Excavated 12 inches and removed compromised soil.
- Tampered the soil for a solid base.
- Poured high-strength concrete footings reinforced with #4 steel rebars.
- Installed a new 4-inch concrete-filled steel post next to the damaged post.
- Fastened steel plates at the top and bottom to securely tie the new post to the central beam.
4. Sill Plate Waterproofing
To stop moisture intrusion at the sill plate:
- Excavated down to 6 inches below the sill plate, exposing the vulnerable section.
- Applied liquid waterproofing membrane to seal the area.
- Installed a physical waterproofing membrane bonded to the liquid rubber for added protection.
Additional Service Notes
- As a courtesy, our team removed cabinets at no additional cost to access work areas.
