School Floor Leveling

Princeton, West Virginia

The Job

The Princeton Middle School in Princeton, West Virginia is a slab on grade masonry structure, and serves approximately 550 students in grades 6 through 8.

The Challenge

The corridor floor in the arts wing settled up to 3.5 inches. A geotechnical investigation was performed, and identified voids up to 2.5 inches below the settled slab. Due to budgetary constraints, the repair needed to address the settlement & instability without requiring flooring replacement.

The Solution

CJGeo mobilized a two person polyurethane grouting crew to the site. Over a few hours they filled all the voids utilizing CJGrout geotechnical polyurethanes, and corrected the settlement. After the floor was lifted back into position and the voids all filled, the custodian reinstalled the cove base at the correct height. CJGeo patched the injection holes with off-white stained grout to match the VCT flooring.
