Step 2: Flush the holes. When you drill, you create concrete dust. If you don’t flush this dust out of the holes, it will be forced into the crack during injection and may clog the crack preventing resin from getting where it needs to go. Put a flexible hose all the way to the back of the hole so that water flushes the dust from the back of the hole to the surface of the concrete. Flush until clean water is flowing.
Step 3: Install your injection port. The port is what seals the hole and gives the injection pump a direct connection to the crack.
Step 4: Flush the crack. Unless water is pouring out of the crack, you will need to inject clean water through the injection port and into the crack.
This serves several purposes:
• Cleans the crack of dirt and other contaminates to allow resin to flow freely.
• Gives you an idea of how far and how easily the resin will flow into the crack when you start injecting the foam.
• Helps to open areas that the resin wouldn’t otherwise flow. Water is thinner than resin and will penetrate deeper and into tighter areas.
• Ensures the resin will have enough moisture to react with.
Step 5: Inject the resin. Always use the lowest pressure that will continuously feed resin into the crack.
High Pressure Advantage
We inject cracks with a pressure of up to 3000 psi effectively sealing the crack with poly urethane. This is much more effective than those do it yourself kits which use low pressurre and never pentrate the crack. They all leak in a few years.
25 yr Warranty
We are so confident we offer a 25 yr warranty which is transferable to the next owner.
