Wolfspeed Materials Facility
Siler City, NC
This project was a $5 billion, 1,800-acre advanced materials
manufacturing facility. Low-Density Cellular Concrete (LDCC)
was selected as the engineered backfill material to reduce
lateral loads and accelerate wall backfill operations.
Annular Space Grout
West Jefferson, NC
Stormwater Slipline Annular Space Grouting:
Rehabilitation of storm drain with new carrier pipe installation
and LDCC annular space stabilization.
Stormwater Abandonment
Camp Lejeune, NC
Abandonment of Stormwater Pipe:
High flowability of LDCC allowed it to encapsulate debris-laden
pipe sections and migrate into surrounding voids.
Large-Diameter Water Line
Abandonment
Charlotte, NC
Abandonment of Large-Diameter Water Line:
LDCC allowed the pipe to be filled efficiently, and minimize
external loads without pipe excavation.
Wall Backfill
Charlotte, NC
New construction adjacent to existing structure:
Lightweight LDCC precisely placed in controlled lifts, reducing
lateral pressures.
Duke Hospital
Durham, NC
Support elevated slab over loading docks:
LDCC significantly reduced dead load and provided the required
bearing capacity for the finished slab.
Foundation Wall Backfill
Charlotte, NC
Support foundation construction in a tight urban site:
LDCC provided uniform support while reducing lateral pressures
on the permanent structure.
Large-Diameter Stormwater
Abandonment
Greenville, NC
Deteriorated stormwater pipe abandonment:
LDCC was used due to high flowability and ability to fill irregular
void spaces without excavation.
Soil Nail Wall Lightweight Fill
Lake Lure, NC
Slope failure destabalized the road:
Soil nails and Shotcrete formed a durable, reinforced protective
wall; remaining voids were filled with LDCC.
Large-Diameter Stormwater
Abandonment
Newton, NC
Abandonment of stormwater system beneath the football field:
LDCC fully filled the pipe system in one day with minimal surface
disruption.
Load Balancing
Lexington, NC
Sanitary sewer pipe sagging, even after previous remediation
attempts: LDCC successfully stabilized the alignment and
preserved pipe geometry.
Pool Abandonment
Duck, NC
Infill of existing indoor pool:
Reduced estimated removal and infill time from 30 days to one
day, fully infilling the pool with self-leveling LDCC.
Westinghouse Blvd. Bridge
Charlotte, NC
Emergency roadway repairs to fix bridge abutment:
Use of Cellular Concrete accelerated construction while
maintaining structural stability.
Wet Well Abandonment
Rock Hill, SC
Abandonment of wet well:
RyanGeo placed 180 cubic yards of LDCC in three controlled lifts
over three days, achieving a total fill height of 12 feet.
