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.
During construction, it is often necessary to form a stable excavation to ensure that any associated movement will not damage neighboring structures or utilities. Keller offers flexible solutions to solve even highly complex temporary support of excavation or permanent support of excavation…
The iconic Hard Rock Hotel and Casino is undergoing a $1.8 billion expansion, with a gleaming 36-story, guitar-shaped hotel as its stunning centerpiece. Such a unique and challenging project requires a wide range of specialist geotechnical skills and expertise – making it ideal for the Keller…
Wet soil mixing, or the deep mixing method, improves the characteristics of weak soils by mechanically mixing them with cementitious binder slurry.
Trench cutting and remixing deep (TRD) soil mix walls are mixed in place using a specialized vertical cutter post mounted on a base crawler machine.
Soil nailing uses grouted, tension-resisting steel elements (nails) to reinforce in situ soils and create a gravity retaining wall for permanent or temporary excavation support.
Compensation grouting, or fracture grouting, is the injection of a cement slurry grout, hydrofracturing soil, and creating lenses. The lenses compact the surrounding soil and lift the overlying soil and structures.
The micropile slide stabilization system (MS3) consists of an array of micropiles, working in tension and compression, that connect as a system using a structurally reinforced grade beam to stop slide movements.
Keller provides geotechnical solutions for the commercial market sector, including office buildings, hotels, distribution centers, retail, data centers, and other structures.
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.
Permeation grouting (cement grouting, chemical grouting, or pressure grouting) fills cracks or voids in soil and rock, permeating granular soils with flowable grouts to create a cemented mass.
Vibro compaction is a ground improvement technique that densifies clean, cohesionless granular soils with a downhole vibrator. It is a technique first developed by Keller in the 1930s that has been used on thousands of projects since.
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.
Aragon Properties Ltd. is establishing a new mid-rise development complex in Port Moody, British Columbia called Platform featuring over 100 one to three-bedroom homes, townhomes, and live/work lofts.
Keller completed work at a new Marriott hotel in Austin, Texas. With Suncoast Post-Tension also on board, Keller has once again demonstrated its ability to offer a comprehensive, seamless service.
