Anchored Reinforced Grid Solutions (ARGS®) stabilise challenging slopes. All slopes with a lack of deep-rooted vegetation, excess water or poor drainage are susceptible to erosion or instability. The combination of Percussion Driven Earth Anchors (PDEAs®) and a facing material strong enough to support the load generated by the PDEA® will work to

The Percussion Driven Earth Anchor (PDEA®) is a unique, modern and versatile device that can be rapidly deployed in most displaceable ground conditions. It offers a lightweight, corrosion-resistant anchor that can be driven from ground level using conventional portable equipment. It creates minimal disturbance of the soil during installation, can

To complement its comprehensive range of tree anchoring systems, Platipus has developed the simple, cost-effective and reliable S2 Zip Anchor, designed to secure a wide variety of landscaping fabrics: ideal for weed control, ground covers and grass reinforcement; reliable alternative to traditional pins or pegs, meaning fewer anchors may be

Mechanical earth anchors for rapid deployment in most displaceable ground conditions. Lightweight and corrosion resistant. Fast and easy to install. Immediate quantifiable loads. Holding capacity up to 200kN. Cost effective alternative to traditional anchoring techniques

Gripple Terra-Lock System is a geotechnical engineering solution designed for slope stability and erosion control. The system uses anchor technology and Turf Reinforcement Matting (TRM) to stabilise slopes, embankments, and water-adjacent structures. Terra-Lock System is designed to work with or replace traditional soil retention and slope

Vibro compaction is a ground improvement technique that densifies clean, cohesionless granular soils with a downhole vibrator. It’s a technique first developed by Keller in the 1930s and has been used on thousands of projects since: reduce foundation settlement; increase bearing capacity, allowing reduction in foundation size or width; increasing

Compaction grouting involves the injection of a low slump, mortar grout to densify loose, granular soils and stabilise subsurface voids or sinkholes. It is suitable for rubble fills, poorly placed fills, loosened or collapsible soils, soluble rocks and liquefiable soils

Permeation grouting, also known as cement grouting or pressure grouting, fills cracks or voids in soil and rock and permeates coarse, granular soils with flowable particulate grouts to create a cemented mass

This technique involves construction of concrete columns with a bottom-feed depth vibrator to transfer loads through weak strata to a firm underlying stratum: as an alternative to piling techniques which generate spoil; avoid piling into deep aquifers; supporting road and rail embankments when other vibro or soil mixing techniques cannot; when a

Wet soil mixing, also known as the deep mixing method, improves the characteristics of weak soils by mechanically mixing them with cementitious binder slurry: road and railway embankments; support of strip, pad and slab foundations when traditional piling methods cannot be used; bridge supports and abutments, wind-turbine foundations; retention

Mixed modulus columns, also known as columns with Mixed Moduli, mixed columns or CMM®, is a sustainable ground improvement method using high deformation modulus columns constructed through compressible soils to reduce settlement and increase bearing capacity. CMM® is the combination of a rigid inclusion for its lower part with a ‘supple’ inclusion

This technique involves the improvement of weak soils by the installation of densely compacted columns made from gravel or similar material with a vibrator. The displacement process reinforces all soils in the treatment zone and densifies surrounding granular soils. This technique was first developed by company founder, Johann Keller, and has been

Driven cast in-situ (DCIS) piles are constructed by driving a closed-ended thick-walled steel casing into the ground and then filling it with concrete. They can be used as foundations for new buildings (residential and commercial), and are ideal for large distribution warehouses, bridge abutments and piers, and floor slabs and load transfer platforms

Rigid inclusions is a ground improvement method using high deformation modulus columns constructed through compressible soils to reduce settlement and increase bearing capacity. Ground improvement efficiency depends on the stiffness relationship between the soil and the columns. Load from the structure is distributed to the soil and columns via a

Pali Radice (literal translation ‘Root Pile’ from the Italian) is a versatile foundation system using small diameter cast in situ bored piles, developed in Italy in the 1950s. It has been extensively employed as an underpinning/stabilisation system for strengthening existing foundations which are settling or are required to support increased

Contiguous pile walls consist of piles arranged in a line typically with a 150mm gap between the piles. Where required the soil between the piles can be stabilised using grouting techniques if necessary, either before or after pile installation. Common uses include the support of excavations, slope stabilisation, and supporting wing walls

Minipiles are a deep foundation element constructed using high-strength, small-diameter steel casing and/or threaded bars. They can be used to provide support to most structures, underpin foundations, enhance mass stability, and transfer loads. A key advantage is they can be installed in locations with restricted access or low headroom, with minimal disruption

Driven precast piles are installed using impact or vibration hammers to a design depth or resistance. They can be used for all types of construction, particularly in aggressive soil condition, and are well suited to sites where the ground conditions are highly variable as they are driven to a set or pre-determined resistance

Compensation or fracture grouting is the injection of a cement slurry grout into the soil creating and filling fractures that then lift the overlying soil and structures. Applications include re-levelling structures, and stabilising and mitigating the settlement of overlying structures during tunnelling

In restricted access situations, where large, heavy conventional plant cannot be used, Keller provides a choice of piling systems such as continuous flight auger, cased CFA, rotary bored, drilled rock socket or driven. A number of Keller's restricted access rigs are able to enter buildings via a normal service entrance or a standard doorway

Bored piles are a very effective, state-of-the-art construction element with many applications in foundation and civil engineering. They are typically used as heavy foundations, and suitable for infrastructure projects such as tunnelling, road or bridge construction, and flood protection, as well as ground retaining and slope stabilisation applications

Helical piles, also known as screw piles, are constructed using steel shafts with helical flights of various sizes to suit the site specific ground conditions. They are a reusable, sustainable product suitable for permanent or temporary installations, with no noise or vibration during installation. They are suitable for most soil conditions, including contaminated soil

Jet grouting uses high velocity fluid jets to construct cemented soil of varying geometries in the ground. It is often the preferred solution in any situation requiring control of groundwater or excavation of unstable soil (water-bearing or otherwise), and can be used to underpin foundations such as quay walls and heavy structures, as well as provide excavation support

Keller offers a complete design and construct service using rotary and rotary percussive drilling methods to install both hollow and solid bar soil nails. We maintain a variety of plant so that they can deal with the challenges of site conditions and productivity targets. With available development land becoming ever more costly, gaining usable
