Foundation Cracks happen for a number of reasons. Considering that tension is a main cause of the crack, the separation of the slab at the point of the crack is bound to expand with any further tension. In areas prone to movement, such as minor earthquakes, it’s guaranteed that the depth and widening of the crack will continue to occur beyond the point of repair over time. Stabilizing cracks immediately when they are evident is important to stop further inevitable cracking with time.
Why epoxy alone is never a solution.
Epoxy is an intended sealant that can keep further moisture damage from occurring as water continues to invade a crack over time. Epoxy consists of two parts – 1.) a resin and 2.) a hardener. The epoxy mixture is a liquid, which contributes to several problems when using it as a fix for cracking.
Some of the major issues with epoxy injection include:
Epoxy will stay in it’s liquid state for hours after injection before hardening. As a result, the liquid will run out the back of the crack, leaving voids that are susceptible to water seeping back in to the crack. As gravity causes the epoxy to settle, this is a guarantee to happen, especially at the top of the crack.
The crack must be completely dry before injecting epoxy. If there is still a moisture leak in the crack, this will block hardening, and can cause channels through the epoxy that will create new leaks in the repair.
Any previous epoxy attempts to a crack will have potentially hardened throughout the crack which means new epoxy applications will not be able to find the right injection spot, nor with they have the ability to flow in to the cracks that have failed epoxy from a previous injection.
Above all, the epoxy is forming a rigid injection that is more prone to cracking, or simply pulling away from the lining of the concrete when more tension is applied – that is, during the next minor shake of the property. While it coats the lining of the crack, it does nothing to keep the crack from becoming a bigger problem tomorrow.
It’s a simple fact. Epoxy is useless to stabilize a crack and keep it from widening and causing further irreparable damage. This is why you need the patented security of Torque Lock Staples.
Using the patented stitching method and staples provided by Torque Lock, as seen in the video, you prepare your concrete for the installation of the Torque Lock Staples. This includes marking the location of the staples in the recommended pattern of 6 inch, then 3 inch, then 6 inch staples at 12 inch intervals, then drilling the required holes for installation and cutting the wall to the insertion depth for installing the staples. Once your wall is prepared for inserting the staples, you can, though it isn’t necessary, then inject the crack with epoxy.
As the staples are inserted, and torqued to the proper compression, the two separated segments of cement will be permanently stabilized with up to 5,000 lbs of controlled compression per staple, guaranteeing that the potential for further crack separation does not exist. When properly applied, the entire length of the crack is permanently secured from further separation. Using hydraulic cement, you can cover the staples and finish the surface to match the surrounding plane.
Torque Lock is applicable to cracks in cement, gunite, shotcrete, foundations, sea walls, fountains and all types of cement structures. Torque Lock is the final fix to stop structural separation. For stabilizing, strengthening and repairing cracked concrete – epoxy is a band aid, not a cure. A structural crack injected with epoxy simply isn’t fixed without the patented Torque Lock Staple.
