Riverfront Convention Center Concrete Floor Lift

Problem

• 12 year old New Bern Riverfront Conference Center’s floors were settling due to silt of an old riverbed subsiding into construction debris that was placed there during the 1970s
• Parts of the floor and patio sunk up to 7 inches
• Cracks and uneven joints in the concrete floors were causing tripping hazards
• Gaps beneath the walls were allowing sound to pass through soundproof rooms

Solution

• Hayward Baker injected the TerraThane 24-003 geotechnical polyurethane to stabilize, void fill, lift, and level the concrete flooring
• The 24-003 was injected using a 5’x5’ grid pattern to ensure optimal spread of the material.
• The injection holes were 5/8”, and the polyurethane ensured minimal impact to the building

Results

• Over 10,000 lbs of the 24-003 was injected, filling the voids beneath the slabs and realigning them to their original grade
• Work was performed around the convention centers operational hours to minimize impact to their business.
• The customer was satisfied with the results and was working with Hayward Baker on two additional buildings
