Construct Deep Foundations System (Micropiles):

To provide support for a new football stadium, Rembco designed and installed a deep foundation system. Though the owner′s original plan called for a uniform layout of 185 piles, 5.5″ in diameter, we proposed a more sophisticated system that incorporated only 120 piles of various diameter. This approach reduced the owner′s costs, met the performance requirements and shortened the time required for our portion of the build. Rembco worked around existing utilities, other contractors and unfavorable weather conditions to meet the owner′s compressed schedule.

Specialty Grouting, Chemical Grouting (Water Stoppage):

Stopped a 350 gpm ground water leak in a rock seam of a coal mine slope tunnel. Grout ports were drilled to intersect the seam at a depth of 10 feet into the rock. 140 Gallons of expanding, hydrophilic polyurethane grout was pumped into the leaking seam. Drilling was provided by the mine. Supervision and grouting was provided by Rembco.

Cap Grouting, Compaction Grouting (Sinkhole Remediation):

At a solid waste composting center, three connected sink holes drained a 4-million gallon process water pond. This caused slope failures in an earthen dam between two ponds. Rembco advanced over 8,000 lineal feet of casing to bedrock, and injected 2,700 cubic yards of mortar-like grout to cap solution features and improve overburden soils. The pond was restored to full service without incident.

Slope Stabilization, Soil Nailing, Rock Anchoring:

Rembco completed multiple projects for a major retail department store. Approximately 150,000 SF of unstable cut face was stabilized using rock bolting with shotcrete facing, rock anchoring, rockfall protection systems, soil nailing, and shotcrete. Project value ranged from $100k to approximately $2M. Soil nail retaining walls ranged in size from 5,000 SF to 12,000 SF with lengths of up to 500 feet and heights up to 35 feet; many had residential properties directly above. Many designs were affected by property lines or utility rights of way. Rock slope stabilization and rock fall protection systems have been completed on cut rock faces up to 125 feet high. Rock anchors were used to construct a cast-in-place tieback retaining wall with a height of up to 60 feet. Multiple tiers of rock anchors were installed to support the 400 foot long, 15,000 SF retaining wall.

Anchored Piles and Lagging Retaining Walls:

Rembco has constructed multiple anchored tieback pile-and-lagging retaining walls to arrest active slope failures and to expand existing right of way for a major railroad company. The work is located at multiple sites in Tennessee, Georgia, and West Virginia. Retaining walls range in size from 5,000 SF to 25,000 SF and have been constructed alongside active mainlines without interfering with the daily operations of the railroad. Wall heights of up to 30-feet were constructed above and below track level. Solid-bar and wire strand anchors were used for permanent wall construction. Anchors were installed into the native bedrock at each site and then tensioned and tested. Lagging and walers were constructed using both concrete and timber.

Anchored Sheet Pile Wall

Rembco has completed a tieback sheetpile wall alongside a canal to provide a barge loading area. The tieback wall utilized driven sheets with soil bonded tieback anchors to resist the crane surcharge loads. Extending for a total length of approximately 800 feet along the canal bank, the tieback wall had a retained height of up to 20 feet with a crane surcharge load of up to 1,000 kips near the top of the wall. Tiebacks up to 100 feet long were installed using mud-rotary drilling techniques in the sands and marine clays alongside the canal. Drilling was completed by reaching over the top of the driven sheet pile above the canal’s waterline.

Radioactive Waste Grouting

Radioactive waste trenches were sealed with cement, microfine cement and acrylamide grout to “lock” it into place. The injection system included 700 sleeve pipes and a manifold that allowed up to eight simultaneous injections. Synchronized, multiple passes were conducted with a computerized data acquisition system. In-situ hydraulic conductivity measurements confirmed our success in reaching target levels.
