Abstract
Embodiments of the invention relate to an on-grade joint-stability system for on-grade concrete slabs. Embodiments of the system may include: a first on-grade concrete-slab portion; a second on-grade concrete-slab portion that is separated from the first on-grade concrete-slab portion by a joint; a first on-grade plate having a first portion and a second portion, the first portion of the first on-grade plate being positioned underneath, and connected to, the first concrete-slab portion, and the second portion of the first on-grade plate being positioned underneath the second concrete-slab portion; and a second on-grade plate having a first portion and a second portion, the first portion of the second on-grade plate being positioned underneath the first concrete-slab portion, and the second portion of the second on-grade plate being positioned underneath, and connected to, the second concrete-slab portion, such that height differentials across the joint are substantially prevented.
