Pepsi Bottling Plant Rocking Slab Stabilization

Problem

• Erosion beneath warehouse concrete slab floor causing uneven joints and rocking slabs
• Forklift traffic travelling over the unsupported slabs caused the slabs to rock up and down and created breaks and fractures called “joint spalling”
• Rocking and unlevel slabs were causing jolts and bumps to forklifts, leading to falling loads and safety issues

Solution

• Clean out all joints and remove the debris
• Inject TerraThane™ 24-003 polyurethane on a 4 ft grid pattern to fill joints, voids and stabilize rocking slabs

Results

• Stabilized over 130 ft of slabs
• Work performed to minimize operational interruption
• Fast cure time ensured the installation locations would be drive-able during the same day as the installation
