Warehouse & Industrial Floors in Harrisonville, MO

Before anyone quotes a new floor, the honest question is whether the old one has to go. The answer comes down to one thing: is the slab failing, or is the ground under it failing? Surface and joint problems are usually repairable. Bearing problems are not — and no amount of new concrete on a bad base buys more than a few years.

Harrisonville has both. The Industrial Park and the rail-served buildings along MO-291 carry an 825,000-square-foot distribution footprint and heavy manufacturing, and much of that pavement is deep into a rehabilitation phase, while the Royal Street corridor is opening genuinely new ground. Same city, two completely different answers.

Here is roughly how we sort it:

• Joint filler failed, edges chipping, panels sound — repair. Clean the joints, re-fill, rebuild the spalled edges.
• Surface dusting or worn traffic lanes, structure intact — repair. Grind and re-harden the wear lanes.
• Slab curling at the edges but bearing everywhere else — usually repair. Grind the high edges and fill.
• Panels rocking or pumping water under a loaded truck — replace. The base is gone.
• Cracks fanning from rack posts, panels stepping at every joint — replace. The slab is under-designed for its load.

If the base has failed, replacement is the only durable option — and the replacement is mostly about what goes under it. Cass County's clay softens with water, and around the rail spurs and older industrial access ground, decades of heavy loading and leaking lines have left it inconsistent.

So we take the slab out, proof-roll the exposed subgrade, correct the soft ground rather than bridging it, rebuild the base in compacted lifts, and seal a vapor retarder against the underside of the new slab. Joints get cut early with a dowel basket for load transfer, and the dock impact lines get an armored joint. A slab poured back onto the base that just failed is a repeat appointment.
