Leaking Cold Joints Repairs in Basement Foundation Walls & Floors – MA, RI, NH & CT

Joseph Coupal - Thursday, May 29, 2014
  1. What are cold joints?

    A cold joint is the joining between the end of one concrete pour that has partially or fully cured and the beginning of a new pour. Cold joints are usually seen when new addition or garage is added onto a house, bulkheads, and even in new construction.

  2. Why do they Leak?

    Cold joints generally leak because this is a weak point in the concrete structure and there are voids at the seam between the two pours. This weak point is caused from the freshly poured, wet concrete, not intermixing with the hardened concrete.

  3. How Much Water can Leak from a Single Cold Joint?

    Homeowners may be surprised by this but 1 leaking cold joint can ruin an entire basement. Gallons upon gallons of water can penetrate through this small void in your basement walls and cause thousands of dollars’ worth of damage.

  4. Are there any signs that a Cold Joint has leaked or is going to leak?

    If you notice a rust color or white powder material near the cold joint, these are signs that water has leak through or is forthcoming. The white powdery substance is efflorescence, which is simply the salts and minerals of the concrete being pushed out from water pressure. If you notice either of these signs the cold joint should be repaired before any serious leaks occur.

  5. How are leaking Cold Joints repaired?

    The good news is that the repair can be achieved through the inside, avoiding costly exterior excavation. A-1 Foundation Crack Repair’s warrantied repair method for leaking cold joints is achieved by injecting a closed-cell polymer resin into the concrete cold joint from the inside.
