My leaky foundation crack started the top right corner and bottom left corner of the basement window well all the way down to the floor. I got a couple of estimates and both companies were asking $900.00. So I went to Google to see what I could find and here I am. This was so easy to do. Total time, prep to clean up was 3.5 hours on a cold Saturday morning.The lower crack cut through the bumpy seams of the concrete forms. I cold chiseled the seam as smooth as I could get, but it was not ideal. I wire brushed the crack area, which created lots of concrete dust. Wear a mask when you do this.One section of the crack was so bumpy, I had to trim the base of the injection port so it would seat more flush. I epoxied each of the ports in place. Careful not to put the port to close to floor, you need some room to work with the epoxy. Mix a small amount of epoxy but it will take longer, as the stuff does harden in about 5 minutes to the point you cannot spread it very well. Tip, Get a box of disposable gloves so you change out the gloves quickly when you get to much on the gloves, you'll go through them quickly. After the ports were epoxied in, I started to seal the crack. I radiated out from the port and stayed on a 2-3 inch line to the next port. I was mixing just enough epoxy for each run between the ports. At the window frame corners, I spread the epoxy over the metal frame. I used roughly 70% of the epoxy in the containers. I started the water filling of the ports. This is where the kit needs some improvement because it does not provide a good method to fill the ports. I took a turkey baster and piece of rubber tubing and combined it with the kits tubing. My crack initially took a lot of water before coming out the port above. As expected, I had a water leak coming out at the frame, so I added more epoxy to that area. Amazingly, the concrete seam that I straddled with the injectors were functioning properly.I was ready to start injecting the polyurethane at this point. Works exactly as everyone in this blog states. I didn't think any was going in because the caulk gun trigger was hard to pull. The viscosity of the stuff is deceiving. Next thing I know is the foam is coming out of the port above and quickly moved to the next port. TIP: Hold the port in with while you are injecting because the back pressure of a small crack will push the port in the closed position. After all the ports were filled, Green foam was visible through the edge of the window frame. Small holes in the concrete also oozzed the blue/green foam. It was awesome. The visible foam is a good indicator that the urethane is expanding and sealing. It continues to expand slowly for another 5 minutes.Here's were I deviated from the instructions. I left the injection ports in.You won't be disappointed in the product, and yes, you can do it yourself. There's even a couple of YouTube videos to increase your confidence and save yourself a lot of money.
