A large warehouse facility was experiencing floor joint damage to their 272,787 square foot warehouse facility. Geological issues below grade and heavy forklift traffic above grade caused the floors to deflect, and encounter some excessive joint damage. These deterioration issues raised a safety concern, and potential lost time and efficiency.
The Witmer Group was brought in to complete a thorough evaluation of the damage floor slab and remedy the situation. A progressive solution was necessary to repair the existing damage and to stabilize the floors for future rigors of above grade stress.
We combined multiple types of floor joint repair methods, along with floor slab stabilization techniques.
Existing floor joint repair: remove the existing filler, re-saw joints to square up spalled edges and install new sand modified MM-80 joint filler. Crack Repair: route out cracks and fill with MM-80 epoxy joint filler. Surface spalls/ defects: remove the deteriorated concrete and patch with Armor Hard Rigid Epoxy Mortar. Joint stabilization- inject high density polyurethane foam for the correction of deflection concrete slabs.
The finished repair was flush with the floor. The Witmer Group provided a smooth and continuous transition that will last for years to come. The floor was now safe for fork lift drivers, which will improve productivity.
