  • Method and system for constructing large, continuous, concrete slabs
    Patent number: 7069703
    Abstract: A method and system are provided for constructing large, continuous, concrete slabs without using conventional shrinkage joints. The system comprises a grid of closely-spaced crack inducers (2) arranged relative to a concrete-pouring surface and adapted to be covered by concrete. The crack inducers (2) may be connected to one another with connectors (10). The crack inducers (2) are of a size, shape and spacing to promote formation of fine cracks in the vicinity of the inducers (2) throughout the slab when the concrete sets.
