Now, regardless of what they consider a tensile strength for their metal rod, it’s literally a bent rod. It has a bent elbow, like rebar, and is – no matter what you’re told, still able to bend when literally TONS of concrete decide to make a move. This isn’t good, because while it may be the least of its weakest points, it’s still a weak point that adds to the potential of failure.
This is why the Torque Lock Structural Staple was invented, and like the AquaStitch – many other companies have created a product in an attempt to mimic what the Torque Lock Staple provides – and they have failed to do so.
The Torque Lock Structural Staple AND method of installation are both patented. This means, only the Torque Lock Structural Staples address the needs of a swimming pool owner when making permanent repairs on structural cracks.
The Torque Lock Staple is designed to add upwards of 5000 lbs of controlled compression to either side of a structural crack. Don’t let other brands fool you with talks of tensile strength, it means nothing when a crack wants to shear or spread. Torque Lock Staples guaranteed a COMPRESSION; this is what keeps cracks from moving. AquaStitche’s mention of tensile strength speaks of how much stress a product might take when movement happens, and frankly, anything glued to a wall has literally zero strength to hold it. Compression, however, is direct resistance against the potential for that crack to move at all. Torque Lock Staples are the only product on the market that applies compression. As for the strength of the staple itself – we haven’t found a level of resistance that can break it yet, and that’s no joke! Even at the pressure of what concrete moving can provide, it doesn’t budge, and we can’t make a whole lot more pressure to test it than a few tons of direct pressure from concrete, so we’re confident it’s what you’re looking for.
When installed, the staples have a patented cam that rotates to provide the torqued compression. There is no oval hole and screw that moves that cam. The cam sets permanently and cannot slide, shift or bend when torqued properly. You don’t need to add epoxy to the underside of it to glue it to the wall, the compression causes it’s staying power, and again, you can’t add enough force to remove it. When it’s in, it’s permanent.
