For Warehouse and Industrial Concrete Floors

Polyurea Joint Filling in Central Florida

Lamphier & Company provides polyurea joint filling for warehouses, exhibit halls, distribution centers, and food plants across Central Florida. We saw cut each control joint to a uniform depth, fill it with two-component polyurea, and shave it flush. At 75°F the polyurea cures in about 40 minutes, so floors go back into service fast.

Why Forklift Floors Need Polyurea Joint Filling

Every saw-cut control joint is a small gap in the slab. Leave it open, and each hard forklift wheel drops into it and strikes the far edge. With a full pallet on the forks, that impact chips the edge, then widens it into a spall, then turns the aisle into a rough ride that shakes loads and wears out wheels and bearings.

A properly installed polyurea joint filler closes the gap so the wheel rolls across instead of dropping in. The filler carries the load from one slab edge to the other, which is what keeps the edges intact. It also keeps out the debris, water, and spills that collect in open joints.

Joint Filler vs Sealant: Where Most Floors Go Wrong

A joint sealant and a joint filler are not the same product. Sealants are soft and elastomeric, made for expansion and isolation joints that move a lot, like the joint around a column or along a wall. Put a sealant in a forklift aisle and it gives under the wheel, so the edges chip anyway.

A semi-rigid filler is hard enough to hold those edges up. ACI 302.1R, the industry guide for concrete floors, calls for a minimum Shore A hardness of 80 on joints that see hard-wheeled traffic. Most floors need both: filler in the saw-cut control joints, and commercial sealants at the moving joints.

How We Prep, Saw Cut, and Fill Each Joint

Many joint filler failures come down to installation, not the product. Filler placed shallow, or over a foam backer rod, has nothing under it and punches down under traffic. Every floor starts with the Lamphier ProGuard Process, then our crews follow the same sequence:

  • Saw cut: existing cracks cut to a uniform depth and width
  • Crack chase: control joints opened to the same uniform profile
  • Vacuum: every joint cleared of dust and debris
  • Tape (optional): both edges masked to stop overfill ghosting
  • Overfill: two-component polyurea placed with a DiamaPro dual-feed pump
  • Cure: about 40 minutes at 75°F
  • Shave: trimmed flush with a 6-inch floor scraper, tape pulled

Spalled Joint Edges Get Rebuilt First

Filler alone cannot fix a joint whose edges are already broken. Small chips can be filled with semi-rigid material. Wider spalls need the damaged concrete cut back to sound edges and the joint nosing rebuilt with a rapid-setting repair mortar. Then the joint is re-sawn and filled like new, so the wheel path rolls flat again.

Freezer, Cooler, and Food Plant Floors

Cold storage floors are hard on joints and hard to shut down. The polyurea Lamphier & Company installs cures at temperatures as low as -30°F, so freezer joints can be filled without thawing the room. The slab should hold its operating temperature for several days first. The same system suits food processing plants and other food-related facilities.

The Lamphier team were professional and great to work with. There were a few unique challenges with our location, building and tenant that we had to overcome. Gary and his team are very knowledgeable and visited the property on many occasions prior to the start of the project to test different products to figure out the best solutions for our building. Lamphier also went above and beyond adding to the scope of work services they did not charge for. I am very happy with how the project went and the finished result. The Lamphier team did a great job and went above and beyond. The crew was professional and polite, especially when interacting with our tenant. I would highly recommend Lamphier!
