These were the straps that were used during the time when your home's foundation was being constructed. After the concrete had cured, the rods were removed and the ends of the ties were carefully broken off. The area where the building device was will leave a hole on the wall where water may be able to seep inside over time.
To take care of the problem, the professionals at Don Kennedy and Sons can make use of an epoxy material to fill in and seal the holes so that moisture will never be able to leak into the basement of your home. This is great news if you are planning on finishing the basement - or even if you aren't planning to - so that you can have a safe, healthy, and dry space.
