Alliance Epoxy Flooring Corp centers every expansion joint project on one goal: fillers that hold, flex, and protect under daily traffic. We are not here to patch joints with quick-dry products that crack in six months. Our focus is on choosing the correct material chemistry for each slab, routing the joint to proper depth, and installing backer rod and filler that accommodate movement without debonding. Every joint we fill is treated with attention to substrate prep and cure conditions, ensuring it performs under forklift traffic, thermal cycling, and the wear your floor actually sees.
Concrete expansion joints need a filler that can handle constant movement, heavy loads, and daily wear without cracking or pulling away from the slab. We use high-performance polyurea and polyurethane materials selected for your floor’s specific traffic and environment. Each joint is routed to proper depth, cleaned, and filled with precision to create a smooth, durable surface that protects your concrete and reduces trip hazards for years.
We measure joint width, depth, and existing damage to determine correct preparation and material selection.
Two-component polyurea or polyurethane is mixed, then poured into routed joints over backer rod installation.
We confirm full cure, test bond adhesion, and verify the joint accommodates slab movement.
We approach every joint filling project with a clear set of principles that never change. Materials are selected for long-term performance under heavy traffic, not short-term cost savings. Each installation step is explained in simple terms so you understand exactly what’s happening and why. Our focus is on proper substrate preparation, accurate mixing ratios, and precise application techniques that deliver reliable adhesion and flexibility for years to come.
Filled joints eliminate uneven edges and trip hazards caused by gaps in your concrete slab.
Prevents water intrusion and debris buildup that accelerate cracking and spalling around joint lines.
Properly filled joints reduce stress concentration during thermal movement and freeze cycles.
Vehicles and forklifts cross joints without jolts or wheel impact damage.
Sealed joints prevent dirt and liquid from collecting in cracks and crevices.
Early filling avoids expensive slab replacement and emergency repairs caused by joint failure.
Expansion joint filler must be installed into clean, properly routed channels with correct backer rod depth to allow movement without debonding. We measure joint width, select the appropriate polyurea or polyurethane chemistry for the traffic load, and mix components to manufacturer specifications. Correct pour technique eliminates voids and ensures full adhesion to sidewalls. This process delivers joints that flex with thermal cycles, resist cracking under forklift traffic, and maintain floor safety for years.
Every joint is routed, cleaned, and measured to ensure proper filler depth and adhesion.
Two-component fillers are mixed accurately and poured to achieve full bond strength and flexibility.
Polyurea and elastomer products resist heavy traffic, forklift loads, and thermal movement.
Customers receive clear explanations of joint condition, cure times, and expected performance outcomes.
If the filler is cracking, pulling away from the edges, or missing chunks, it needs replacement. Failed joints create trip hazards and allow moisture penetration.
We use polyurea, polyurethane, and epoxy fillers depending on traffic load, movement, and chemical exposure. Each material offers different flexibility and durability properties for your floor.
Yes, industrial-grade polyurea and polyurethane fillers are engineered to handle constant forklift and heavy equipment loads. Proper installation and curing time ensure lasting performance under demanding conditions.
Most projects take one to three days depending on total linear footage and joint condition. We route, clean, install backer rod, and pour the filler in stages to ensure proper adhesion.
Yes, backer rod is installed in every joint to control filler depth and prevent hollow voids underneath. It ensures the filler bonds properly to both joint edges and moves with the slab.
