Finishing & Remodeling: Unfinished Basement Remodel

We also applied waterproofing cement on the floor before installing modern floor tiles, completed electrical work, and added lighting and paint, transforming the basement into a beautiful, functional space.

Basement Cracks Repair

  • Problem: The client had numerous cracks in the concrete surface of the basement, causing water leaks.
  • Solution: We excavated the existing concrete surface to a minimum depth of 3” and installed new waterproofing cement. This not only repaired the cracks but also prevented future water intrusion.
