Concrete Floor Joint Filling

Virtually all interior floor slabs have saw-cut control, contraction, and construction joints. Over time, heavy point loads from material handling equipment, i.e. forklifts and pallet jacks will break the edges of these joints, causing them to spall out and worsen over time. A floor joint that has been properly cleaned, prepared, and filled with a joint filler will minimize or eliminate this damage.

Ace Avant’s Specialty Division installs over 500,000 linear feet of interior slab joint fillers annually. We are a multi-manufacturer approved applicator, have state of the art dual component, joint filling pumps, as well as gas, propane, & electric  powered clean out saws and vacuums that are used to properly prepare these floor joints.


Ace Avant’s Specialty Division provides slab stabilization and slab underpinning services.  The injection of a high density, structural grade polyurethane foam inside voids underneath settling or rocking concrete slabs can support them without excavation and added weight. The polyurethane material is fast setting and fast curing, to minimize any possible downtime.

Concrete slab curl as well as material handling operations that take place repeatedly on the surface of a concrete slab often cause concrete settlement and voids under the slab to occur. These slab on grade concrete surfaces can become unstable as well as dangerous. These problems become intensified in commercial/industrial warehouses that use heavy, solid wheel forklifts and other material handling equipment.
