Easiest installation of any expansion joint replacement product


Welcome To Trim-A-Slab Expansion Joint Repair

Sitemap Trim-A-Slab is a product made from exterior-grade materials designed to replace rotten or missing wood often found in driveways and sidewalks over 5 years old. It offers many advantages over the tube-dispensed gooey stuff that has been about the only option available for years. Trim-A-Slab installs incredibly fast, looks great, and can be removed and replaced in case you need to run wires for outdoor lighting across your driveway. Additionally, Trim-A-Slab is very durable; we guarantee it for up to 10 years.
