Throughout the industry, for years, rebar was considered the solution to repair cracks. Repairs worked short term, leaks continued and most of the time, the process of installing rebar to make repairs actually made for leaks. By burrowing into the gunite, then repairing concrete, the area dug into creates an entirely new area that will eventually crack and leak. At best, rebar crack repair is a temporary band-aid measure, but ultimately, it’s like trying to repair a car window with a plastic trash bag. It might stop the rain for a little while, but it’s not a window. When it comes to concrete, you repair it with concrete, and for the crack – you add a controlled compression to keep it from spreading open and causing water loss and long term damage.
When properly installed, Torque Lock Staples put pressure against both sides of the crack. This pressure keeps the crack from spreading open, which is what cracks want to do. Pressure behind them wants to push them apart.
Newton’s 3rd law states: for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A.
So, what’s behind a wall wants to push force on the wall and make it crack. That’s where the Torque Lock Staple puts force back into the wall and keeps it from moving. The staples offer upwards of 5000lbs of compression to resist the force that’s trying to open the wall of your pool. In the end, when the staples are inset, that wall isn’t moving. The crack is stabilized and when you penetrate the crack with concrete and refinish the pool, it’s fixed. permanently.
