Tunnel Support

Somerville, New Jersey- utilizing a guided boring machine for sleeve port pipe installation, Constellation Group LLC provided technical and field support to install nearly 80,000 gallons of sodium silicate grout for a tunneling operation under active railroad tracks.  With four sets of dual component pumps operating, an average of 3000 gallons of grout were pumped daily.  The equipment was designed by CGLLC and built by the contractor. This project is discussed at length in this paper: Support of Tunneling with Chemical Grouting in New Jersey; presented at NASTT 2012.

Spillway Stabilization

Dennis, New Jersey- using two different  rapid setting urethane grouts and sleeve port pipes, erosion under a small environmentally sensitive dam spillway was minimized.  Grouts were supplied by Avanti.

Water Control

CGLLC has long-term experience in ground stabilization to control water infiltration and flow.  Work includes quarries and mines, including positive hydrostatic pressure situations.  Some notable projects include Millville Quarry, WV, Texas Quarry, Maryland and Rittenhouse Square, Philadelphia.
