Abstract
A novel technique and seal-and-filling support for longitudinally extending concrete floor joints comprising a resiliently compressible cylindrical support member of cross-dimension similar to or lesser than the joint opening and compressibly inserted into the joint to seal the base thereof and to support thereupon and there along a semi-rigid epoxy filling the joint above the support and up flush to the concrete floor, and with the support having external longitudinally extending ribs or fins, and having hardness substantially matched to that of the epoxy filler.
Claims3
A method of sealing and supporting fillings in concrete floor joints and the like each having a joint opening and a bottom, that comprises, during floor construction and preparation, inserting a resiliently compressible cylindrical support member into a joint opening of a longitudinally extending concrete floor joint of lesser cross-dimension to lodge the member at and along the opening in order to retain moisture in the curing of the concrete at the joint, while sealing the opening from the entry of debris into the joint;
- following the concrete hardening, pushing the compressed support member to the bottom of the joint to seal the bottom;
- and filling the joint above the support member with semi-rigid epoxy filler flush with the concrete surface on each side of the joint;
- the hardness of the compressed support member being substantially matched to the hardness of the epoxy filler to prevent any substantial depression of the filler as vehicle wheels ride over the filled joint.
