In 2004, frustrated with traditional crack repair methods, including epoxy injection, re-bar, etc., Torque Lock founder and inventor Darren Merlob developed a revolutionary technique for repairing structural cracks – the Torque Lock Staple. Built stronger, easier to use and guaranteed to deliver a controlled compression that stays – Darren’s device earned a Patent and has since been used world wide. That’s 7 Continents, hundreds of countries and in thousands upon thousands of applications. It’s the proven solution to structural cracking!

All Torque Lock Staples are made in house. This is how we guarantee consistency and quality control. Because the Torque-Lock ™ staple is used to repair and stabilize cracks in virtually any structure composed of cement, gunite, concrete, poured block and more, we insist that production is kept in house to ensure customers of only the best quality of their build. Applications include swimming pools, spas and fountains, concrete foundations, garage and basement floors, sea walls – if it’s concrete and it cracks, Torque Lock is there, and it works.

Using its patented Cam Lock™ technique, it stabilizes cracking by creating up to 5000 lbs of compression torque for each staple installed. When applied in the recommended stitching method, also patented, the end result is durability, strength and support.

When designing the Torque Lock™ staple, we kept 3 things in mind:

  • Easy Installation
  • Visibility
  • Guarantee


A 10 foot concrete crack can be repaired in as little as 1 hour. You do not need to be a professional contractor to install the staples. handy with tools helps, but be assured, complete video instruction is available here on the website and you can see how the process is done. while we may recommend hiring someone familiar with concrete and structural repair to do the job, it can be done by literally anyone.


The Torque Lock™ staple countersinks into the existing concrete structure allowing the installer to apply plaster, marcite, tile, exposed aggregate finishes, Chattahoochee, cool deck, or any other surface to create a finish like there was never a crack to begin with.
