As the winter season has passed and contractors are getting to repairs on public use land, one of the barriers that holds back safe public use is damaged retaining walls. They are built for a reason, and maintaining their structural integrity to literally, retain what’s behind them, is best done with solutions that make permanent repairs. For solid block retaining walls, that product is Torque Lock.
Australian contractor Steve Pisceteck explains, “We are lucky in the sense we have relatively benign soils in most cases. Different soils behave very differently, and along the coast the dune sands are very benign. But then as we move towards the hills, we start getting into clays. Clays tend to swell and shrink much more rapidly when the moisture content changes. And that’s generally where we see more of the structural problems.”
As structural cracking begins to show in weakened areas, getting the crack stabilized immediately keeps the integrity of the wall intact so cracks don’t widen or lengthen when soil movement takes place. By stitching the crack with Torque Lock Structural Staples, the strength of the wall stays in place.
Installing a Torque Lock Staple every 12 inches along the linear footage of the crack applies a controlled compression that doesn’t allow the concrete to spread. Where the applied pressure of shifting soil behind the wall presses against its back side, the compression made by the staples holds the wall in place. Repaired concrete stays in the crack and repaired walls retain the weight of what they are holding back.
