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

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

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

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

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

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

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

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

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

Dynamic compaction involves the controlled impact of a crane hoisted weight, of around 10-12 tonnes, falling in a pre-determined grid pattern to improve loose, granular and mixed soils and fills: increase bearing capacity; decrease settlement; mitigate liquefaction; avoid major below-ground obstruction removal. Dynamic compaction is a ground

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

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

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

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

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

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

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

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

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

Continuous flight auger (CFA) piles are drilled and concreted in one continuous operation enabling much faster installation time than for bored piles. Reinforcement is placed into the wet concrete after casting, enabling the pile to resist the full range of structural loading

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

Rock grouting is normally done in fissured rock to reduce the flow of water along the joints and discontinuities in the rock. Applications include: reducing conductivity/transmissivity via interconnected porous zones in an aquifier; increasing resistance against deformation

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

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
