This Marion, NC carport was sinking over the years. Within the last year the problem became increasingly worse, causing rain water to pool up just by the home’s entrance door.
Tar Heel Basement Systems lifted and restored the sinking slab by injecting a two-part structural grade foam beneath the carport called PolyRenewal. The expanding foam stabilized the soil beneath the slab, allowing the carport to raise back to the appropriate level in half a day. The homeowners were able to use their carport just thirty minutes after installation was complete.
