Jon Yankasky | DIY Repair Methods - Oklahoma City

Industry leaders including Jon Yankasky convey that there are several DIY methods for repairing minor cracks in the foundation, depending on the size and severity of the crack. For hairline cracks, applying a waterproof sealant or concrete patching compound can effectively seal the crack and prevent water infiltration. Clean the crack thoroughly, apply the sealant or patching compound according to manufacturer instructions, and allow sufficient drying time before assessing the results.

For larger cracks, consider using hydraulic cement, which expands as it sets to fill and seal the crack effectively. Use a trowel to apply the hydraulic cement into the crack, ensuring it reaches the full depth and width. Smooth the surface and allow the cement to cure completely before checking for any additional cracks or signs of water leakage.
