Problem

  • Soil Subsidence and erosion caused voids beneath the Seneca Rocks Discovery Center’s concrete slab foundations
  • Some slabs were left with dips of up to 3”
  • Settlement occurred in the Center’s conference rooms, hallways, bathrooms, and patio, causing tripping hazards

Solution

  • Remove existing caulking and drill 5/8” holes through the slabs, causing little dust or disruption
  • Inject the TerraThane 24-003 geotechnical polyurethane underneath the slabs to stabilize, voidfill, lift, and level the slabs
  • Add drainage, new caulking and cleanup the areas with minimal disruption to the center’s activities

Results

  • Filled all voids and leveled slabs
  • Added minimal weight to the area when compared to concrete grout (4lbs vs 130lbs)
  • Tripping hazards were mitigated
  • Completed in 3.5 daysSaved thousands of dollars by avoiding replacement or versus alternative methods
