Anchor block slope stabilization remediates slopes or existing retaining walls using anchored reaction blocks.
Soldier piles and lagging retains soil, using vertical steel piles with horizontal lagging. Whether an open or low headroom site, Keller has the equipment and experience to design and construct the optimal solution.
Diaphragm walls are very rigid walls that offer significant resistance to bending from lateral loads and are water-resistant.
Slurry walls create barriers to groundwater inflow or subsurface contaminants.
Sheet piles are steel sheets with interlocking edges that retain soil and are installed using vibratory and vibration-free rigs.
Gabions are rectangular, interconnected, stone-filled wire baskets formed from welded or woven mesh to form an aesthetic retaining wall.
CFA / ACIP piles (continuous flight auger piles, auger cast piles, or augered cast-in-place piles) are cast-in-place piles using a hollow stem auger with continuous flights.
Drilled shafts are high-capacity deep foundation systems, also known as drilled piers, caissons, bored piles, or cast-in-drilled-hole piles (CIDH).
Micropiles (mini piles, pin piles, needle piles, and root piles) are deep foundation elements constructed using high-strength, small-diameter steel casing and/or threaded bars.
Rigid inclusions (RIs) are high modulus/controlled stiffness grout columns typically installed through weak, highly compressible soils to reduce settlement and increase bearing capacity.
Vibro piers® (also known as aggregate piers) are stiff aggregate piers constructed to reinforce fine-grained soils. Our company founder, Johann Keller, developed this technique, which has been used on thousands of projects since.
Vibro stone columns, or vibro replacement, are the construction of dense aggregate columns (stone columns) with a down-hole vibrator suspended from a crane or specially built rig.
Wet soil mixing, or the deep mixing method, improves the characteristics of weak soils by mechanically mixing them with cementitious binder slurry.
