Pier Top Poured Without Commercial SureTopsThe photo to the left shows a pier top that was poured without the use of Commercial SureTops. Essentially, the result is an unintentional pier cap. When soil beneath the slab expands, the mushroomed top of the pier results in a binding of the soil against the pier top, raising the pier and causing stress cracks in the slab itself. |
Pier Top Poured With Commercial SureTopsThe photos below show pier tops that were poured with the use of a corrugated paper (left) and corrugated plastic (right) Commercial SureTops. Because the tops of these piers remains true to the shape and diameter of the main pier body, no angular pressures are exerted on the pier top that might result in an uplifting of the pier and cracking of the slab. |

Flat Commercial SureTopsThis compact product is pre-scored and shipped flat. When ready to complete the concrete placement in upper portion of the caison, simply open, shape, install and fill manually to required elevation. |
|
Wrap-Around Commercial SureTops™Factory scored for easy shaping, one-step assembly allows easy use in traditionally difficult areas that are not suited for one-piece rigid forms. Use this style to shape piers with long rebar projections, or returns that are larger than form diameters. Unroll, place around reinforcing bars, position interlocking ends, insert wooden spline connector, and position into upper portion of caison. Fill manually to required elevation. |
Commercial SureTops™ vs. Fiber TubingBy comparison, traditional fiber tube uses 24 times more storage than flat Commercial SureTops™. To obtain 96 usable 24" pieces would require 80 saw cuts with fiber tubing! |
