Specifications include, but are not limited to: 1. This project proposes to service approximately 3,000 – 4,000 sidewalk slabs, and an undetermined amount of street pavement slabs, of varying dimensions by mudjacking method using a slurry mixture. The proposed work is to correct alignment of offset slab joints and/or to elevate slabs so as to establish slope to eliminate areas of standing water. 2. Each ton of grout to be pumped shall consist of approximately 1,680 pounds of powdered limestone (containing a minimum of 90% calcium and magnesium carbonates graded so that 100% pass a 60 mesh screen, 85% pass a 100 mesh screen, and 60% pass a 200 mesh screen) and no less than 320 pounds of Portland cement. 3. Dry material is to be mixed with only potable water using mechanical mixing equipment capable of producing a uniformly mixed grout of the proper consistency. The grout should not exceed a 5” (five-inch) slump. Pump aids, mix additives or waterproofing agents may be added at this time if desired or needed. Grout mixture will provide 80 psi strength and no expansive or shrinkage qualities.
