More Detail on the waterproofing process and certification?
Excavation and support of excavation for a footprint storage facility in College Point Queens, New York, was a project that included overhead utility challenges, adjacent structure concerns, waterproofing, and 500 cubic yard concrete pours.
A slab on deck foundation for this 30,000 sq. ft footprint was accomplished in phases as the excavation elevations were attained section by section. Over 2,000 truckloads of soil were removed from the project to make space for the three basement levels within the storage facility. (Four floors above grade would eventually complete the structure under a separate contract.)
Sandyston Contruction’s <SPECIFY> certified waterproofing unit applied <SPECIFY> process and materials for meeting the contractual criteria for water and moisture control.
Along the southeast corner of the excavation was a commercial single-story structure that was addressed with pressurized injections into the underlying sands and clays. The SOE wall adjacent to this structure was 13 3/8″ dia. drilled pipe pile soldier beam and lagging, installed in 10′ sections via an HD 200 rotary drill. This crawler foundation drill model is capable of torque up to 43,300 ft. lbs.
A Juntann piledriving <SPECIFY> rig drove H-piles for the remainder of the soldier piles to finish the perimeter of the excavation wall. R63 hollow bar was installed and grouted as tiebacks. Rakers and walers were also installed in the southwest corner of the SOE to complete the earth retention structure.
