Juneau - Jordan Creek Slipline

Year(s): 2012
Overview:

Slipline a 120' long aluminum CMP section inside of an existing 8' deteriorated CMP pipe carrying Jordan Creek underneath the Juneau Airport. Difficult problems of high ground water levels from tidal inflow on one end and Jordan creek on the other were overcome by preliminary patching of host pipe and injecting multiple lifts of low-density grout to offset the buoyancy force of the liner pipe. MCGA consulted on the preparation and installment of the slipline and then mobilized equipment and personnel to produce and inject low-density grout to fill the annular space between pipes. 55 lb grout was produced to achieve 500 psi for the project.

2007 - Fill the void, stabilize and lift the 150' x 80' slab in the maintenance shop at Pogo Mine, which is 60 miles east of Delta Junction, deep in the Alaska Range. About 100 yards of low-density grout was used as an insulation barrier between frozen ground and the warm shop floor. In addition to filling the void, the sinking 12 inch thick reinforced slab was also jacked back up about 6 inches.

Seward Lowell Creek Tunnel Reconstruction

Year(s): 2003
Overview:

In 2003 Alaska Concrete Technologies provided 350 yards of 12,000psi+ silica-fume concrete during extreme winter conditions for the Lowell Creek Tunnel Relining in Seward. Even though Seward has ready-mix plants, they did not have suitable aggregates, or experience to procuce 10,000 psi concrete.Pre-weighed super bags were filled with specially screened aggregates by ACT in Anchorage, and then trucked 150 miles to Seward, along with bags of cement, and admixes.  The bags had to be covered and heated and then batched with heated water to produce the high-strength concrete in sub-freezing temperatures.A portion of the approach flume to the tunnel had water running through porous rocks underneath, creating hydrostatic pressure forcing water up the wall and out cracks. A special expanding grout was used to fill the void and seal off the water.
