Darren Merlob is a small business owner who has been a pioneer in the swimming pool business for more than 20 years. In 1989, starting with just a few pools on a service route, Darren grew to become one of the largest, most profitable pool renovation companies in South Florida.
In 2004, frustrated with traditional crack repair methods (epoxy injection, re-bar, etc.), he developed a revolutionary technique for repairing structural cracks using a patented compression staple.
Today, the Torque-Lock ™ staple is used world wide to repair and stabilize cracks in cement and gunite.
The Torque Lock™ Staple is a revolutionary technique used to repair structural cracks on any solid cement based surface. Using its patented Cam Lock™ technique, it stabilizes the concrete crack by creating up to 5000 lbs of compression torque for each staple installed.
When designing the Torque Lock™ staple, we kept 3 things in mind:
- Easy Installation
- Visibility
- Guarantee
Installation:
A 10 foot concrete crack can be repaired in approximately 1 hour.
Visibility:
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.
Our Guarantee:
Our Torque Lock™ Staple is Guaranteed. Its that simple (see warranty for full detail.)
Kits:
Three Torque Lock Kits are available:
Sizes:
The Torque Lock™ Staple is available in two sizes 3” and 6”. The cams are interchangeable and a ratchet attachment found in your local home improvement center is all that’s needed to turn the cam.
