Our techniques apply when adding new structures: especially rock anchor, microfine cement, soil nailing, micropile installations for foundation support. We specialize in slope stabilization, anchors, permeation grouting, foundation repair and support, grouting, soil nails, rock drilling, micropile installations, and sinkholes. We use a problem-solving approach geotechnical architecture of buildings, bridges, water plants, sewage plants, tunnels, sinkholes, caisson, shoring, underpinning, agriculture, and roads construction. We are experienced in these applications: micro piles, sinkhole repair, permeation grouting, pressure grout, soil nails, chemical grouting, micropiles, compaction grout, and rock anchors. Our specialties are rock anchor, acrylamide and compaction grouting, mini piles, sinkhole repair, micropiles, acrylamide grouting, and soil nailing. We will continue to dedicate ourselves to excellence, including insurance mortgage, in our performance, in our integrity, and in our relationships with our customers. We will carefully weigh our decisions, actions, and results to make sure that we remain the most trusted name in the geotechnical contracting industry.

Figure 4-2: Footing Retrofit (increase footing size and add top mat of rebar)
Typically, columns are located at the center of spread footings, whereas retaining walls are
eccentrically located in relation to the centerline of a continuous footing.
Combined footings are generally required when loading conditions (magnitude and
location of load) are such that single column footings create undesirable engineering
problems, are impractical, or uneconomical. For example, locating a column at or near a
footing edge will invariably result in a soil bearing pressure that exceeds the allowable
bearing capacity of the soil mass. Other potential engineering problems associated with
edge-loaded footings are excessive settlement and/or footing rotation. The results of footing
rotation on soil bearing pressures can be seen in Figure 4-3.
These problems can be eliminated, or at least minimized, by combining an edge-loaded
footing with an adjacent single column footing. This is generally accomplished by one of
two methods. In the first method, two footings are combined to form a single rectangular or
trapezoidal footing. This type is referred to as a combined footing. In the other method, two
