We were called out to a house because the homeowner kept getting water in one of the basement bedrooms. They were not sure if it was coming from the bathroom next to the bedroom or not. They had called a plumber and another contractor prior to calling us. Neither were able to find the cause of the leak. Once we got onsite we quickly determined it was a foundation leak at the cold joint. The house had an addition built on the rear of the house and one of the additional foundation walls was in the approximate location of this leak. We assumed when they dug down to virgin grade to pour the foundation walls they may have damaged the original drain tile in this area. This can cause water to back up and eventually with the right circumstances force through the cold joint and into the house.
You can see in this picture the water staining on the base board. It was more present under the window but not in the closet. This led us to the general area of where the water was coming from.
Once we removed the drywall and the wood studs. We removed a small portion of the basement slab floor. This was to expose the house drain tile and cold joint. You can see in the picture above the exact area where the water was pushing through the cold joint. We inspected the drain tile and found it to be in working condition and it did not need to be replaced.
We then backfilled the area with clean river washed gravel to aid in drainage and placed the Hydraway 300 bridging material over the cold joint to direct the water into the drain tile on the interior of the wall. This will prevent the water from coming into the bedroom again.
We then repour the slab floor to original strength and thickness.
This was another successful waterproofing job with excellent results. We completed this repair in about 2 hours and the customer was ready to put the room back in about a week after this once the floor dried.
If you have a leaky basement or bowing walls don’t hesitate to give us a call.
