Finally A Crack Repair System For Do-It-Yourselfers That Works Since the first hard tennis court was built we have been filling cracks with everything from cement to rubber, only to have them relentlessly re-appear. Until recently, there have been only three options: live with the cracks reappearing every Winter, re-fill them every year or two, or perform some kind of major reconstruction. It has been equally frustrating for court owners and contractors. Finally, there is a fourth option. A long-term crack repair system that doesn't fight the structural movement of the court slab around the cracked areas. CrackSpan (patent pending) covers the crack and surrounding court area with a flexible, yet tough, membrane that stretches and contracts with the movement of the slab. The cracks are still opening and closing, they just don't reflect through the membrane. How does CrackSpan Work? After a crack has been filled with a typical latex cement patching compound and allowed to dry over night, our 24" wide membrane is centered and glued down over the crack everywhere except an 8" strip in the middle (4" on either side of the crack). This 8 inch non-adhered middle area of the membrane can easily absorb the movement of a crack as large as 2 inches without affecting the tennis coatings and cannot be seen or felt by the player. The cracks are still there and are expanding and contracting slightly around the crack filler, but they are hidden and protected by the membrane. Freezing water, dirt and dust which will cause a crack to widen over time cannot enter through the CrackSpan membrane. What Makes CrackShield Better? There are two key innovations we believe set CrackSpan apart from similar systems. Number one, we provide a strong, waterproof, adhesive with our kit. The other systems only recommend the use of a concentrated tennis court coating called 'Acrylic Resurfacer'. Even in concentrate form it has, at least, 60% more water than our adhesive. Less water + More Adhesive = Stronger Bond. Our second major innovation is the use of, what we call, a soft coat between the court surface and the special CrackSpan membrane in the 8" center area. This soft coat does not adhere to the court surface or the CrackSpan membrane, insuring maximum free movement of the membrane as needed. Since we don't use tapes or other types of slip-sheets, you won't hear that hollow sound (as if there is paper) beneath the membrane when a ball strikes it. For CrackSpan Pricing 'Click Here'
