Crumbling Foundations from Pyrrhotite

To date, we have not found a repair that has been successful related to crumbling foundations from pyrrhotite. Keep in mind that not all foundation cracking is related to pyrrhotite and not all mapping cracks related to pyrrhotite lead to failure of the foundation.

3 Ways to Repair a Foundation

  1. The most common and also most expensive method is replacing the foundation with a poured concrete foundation. This is expensive because the house has to be jacked up, all utilities have to be disconnected, and exterior landscaping will be disrupted. The average cost ranges from $170,000 to $400,000. The state of Connecticut’s program only covers reimbursement for the replacement of the foundation itself. The program does not reimburse for exterior porches, landscaping, patios, etc.

  2. The second method is replacing the foundation with cement block. This tends to be cheaper and just as successful. The average cost for this can range from $60,000 to $180,000. Some downsides to the cement block method are that if the blocks are hollow, you risk them getting moisture penetration which can cause wood decay and insect damage to sills. It is also vulnerable to earth backpressure which may lead to cracks in the future.

  3. The third method we are familiar with is using foundation fiberglass resin panels. Unlike the other two methods, this one would not require you to raise the house or disconnect utilities, so people can continue living in the homes throughout the process. There might be disruptive machinery on the outside, but residents can at least continue living on the inside with all of their utilities still working. If grading and gutters are done properly, it is unlikely you will get water intrusion through panels. Furthermore, the panels can be insulated for higher R-Value (a rating given for insulation). The average cost of this method ranges from $80,000 to $160,000.

To determine which method will be the best option for your foundation: first determine a time frame, check with local contractors for pricing, and review the CFSIC reimbursement program requirements.
