Problem:
A homeowner in Northport, NY experienced water intrusion in a finished basement room and the adjacent boiler room. The water damage affected the drywall, studs, and baseplate and posed a risk of mold growth and structural weakening. Immediate action was needed to stop the leaks and restore the affected areas.

Solution:
Our team implemented a detailed repair and waterproofing process:

In the finished room:

• Cut drywall 24 inches above the floor along the entire 23 linear feet of the affected wall.
• Removed the studs and baseplate to access the concrete floor and wall cove joint.

At the joint:

• Ground the wall 3 inches vertically and the floor 3 inches horizontally with a diamond blade to remove efflorescence, dirt, and mold, exposing the original cement surface.
• Injected urethane and epoxy formulations into all penetration points to seal leaks from within.
• Applied one layer of Basecrete waterproofing cement over the cleaned surface.
• Installed reinforced 4.5oz Basecrete fiberglass mesh waterproofing cement along the length of the joint.
• Applied a second layer of Basecrete waterproofing cement for additional protection.

Finishing:

• Installed new drywall, then taped and compounded it for a clean, finished appearance.

Conclusion:
This Northport project demonstrates how comprehensive waterproofing combined with structural repair can effectively stop water intrusion and prevent future damage. Using proven materials like Basecrete and injection techniques ensures lasting protection.
