Problem:

The homeowner noticed water intrusion in the basement, and further inspection revealed a structural crack in the basement wall. This damage compromised both the stability and waterproofing of the foundation, increasing the risk of further deterioration and water damage.

Solution:

Work Area A: Structural Crack Repair and Waterproofing
We began by drilling every 6 inches vertically along the entire length of the crack from top to bottom. We injected epoxy and urethane formulations into these points to stabilize the wall structure and provide a watertight seal. Once stabilized, we applied a strip of Basecrete 4.5 oz mesh-reinforced waterproof cement over the crack to create a durable protective layer.

Work Area B: Floor-to-Wall Joint Reinforcement
 At the base of the wall where it meets the floor, we ground 3 inches vertically and 3 inches horizontally along the entire joint using a diamond blade. We then applied Basecrete 4.5 oz mesh-reinforced waterproof cement the entire length of the joint, extending 4 linear feet to the left of the inside corner, for a total of approximately 24 linear feet. This ensured complete waterproofing and structural reinforcement of the vulnerable joint area.

Conclusion:

Through precise crack injection, reinforced cement application, and joint sealing, we restored the integrity of the basement wall and stopped water intrusion. The homeowner now has a structurally sound and dry basement, with the repairs designed to last for many years.
