Chula Vista, CA – Construction of a 17,000 square foot Soil Nail wall to provide earth retention for the construction of new Clear Well water storage tanks. The wall measured approximately 54 feet at its tallest point. Over 500 cubic yards of Shotcrete was installed in addition to 530 soil nails ranging in length from 25 to 52 feet deep. Excavation for the wall required in excess of 35,000 cubic yards of grading.
This local carwash business had been faced with the duration and expense of constructing both a Shoring Wall and a Cast in Place Concrete Wall. Groundforce was contacted for our expertise in Shoring Walls and the client called us to see about an alternative approach.
Soil Nail Wall Design
We gave them a Design/Build proposal to do the job using a permanent Soil Nail Wall. Groundforce Team are experts with Soil Nail Wall and other retaining wall structures.
This is an interesting video showing CAT 259 excavation equipment dropping in on a 1.5 to 1 slope.
The Cat 259 Compact Track Loader, with its vertical lift design, delivers extended reach and lift height for quick and easy truck loading. Its standard, suspended undercarriage system provides superior traction, flotation, stability and speed to work in a wide range of applications and underfoot conditions.

Soil nailing is a construction remedial measure to treat unstable natural soil slopes or as a construction technique that allows the safe over-steepening of new or existing soil slopes.
Groundforce can be seen here providing down hole hammer drilling in Temecula, CA. Serpentine Soil Nail Walls are challenging to build but look good when they are finished and provide quality support. This one is for an estate site that will have a pool at the base of the wall.

Here is some fun footage of a job we just wrapped in in San Diego for an apartment project in the Mission Hills area. Groundforce did all of the Soil Nail Wall Work and Grading. Our guys really did a great job on this one. On to the next job!
Spring Valley, CA – A roadway improvement project to increase pedestrian safety. Cast in place retaining walls were constructed at existing side slopes to widen the street for sidewalk and curb ramp construction. In addition to the 2700 square foot cast in place retaining wall a 4250 square foot soil nail and shotcrete retaining wall was constructed in order to cut back a slope on the opposite side of the street.
Working under contract with the City of Alhambra, Groundforce has just completed the Grandview Drive Wall Stabilization Project. The work included installation of 125 Soil Nails, 180 Cubic Yards of Reinforced Shotcrete, Wrought Iron Fencing and a Plaster finish at the shotcrete wall.
The project Geotechnical Engineer was David Colbaugh with Evans, Colbaugh and Associates. Soil Nail wall design was by Ricardo Jordan with Earth Support Systems, Inc.
