Franki Africa Offices

Franki is the largest, oldest and most established specialist geotechnical contractor in Sub-Saharan Africa.

Brief Company HistoryFranki Africa has been operating in Sub-Saharan Africa for more than 70 years.

Franki Africa was originally founded as a branch of Frankipile, a Belgium-based international geotechnical company established in 1909. The Franki Piling Company of South Africa was founded in 1946. In the many years that it has operated in Africa, Franki has developed a powerful organizational culture. Three Core Values guide the business:

� RESPECT for colleagues, suppliers and customers,

� PROFESSIONALISM – the application of skill and diligence in the delivery of all our projects, and

� INTEGRITY – consistently acting with honesty, fairness and positive intent in everything that we do.

These Core Values remain key to the success of the organization.

In November 2013, Franki Africa was acquired by Keller, the world’s largest independent geotechnical contractor renowned for providing technically advanced and cost-effective geotechnical solutions anywhere in the world.As part of the Keller Group, Franki Africa has access to many new technologies and innovative products.

Piled Foundations

Piling involves the installation of structural elements to transfer foundation loads through weak soils to stronger underlying ground.

Franki Africa offers an extensive range of pile types including:

� Franki Driven Cast-in-Situ PilesThe Franki pile has been used extensively throughout Southern Africa for over 70 years and is still today one of the most popular pile types, due to its excellent load/deflection performance.

� Precast PilesPrecast piles can provide an economical solution, especially in deeper soil profiles.

� Driven Tube PilesThis system can achieve considerable depths (> 60 meters in a suitable profile) and is commonly used for river bridge foundations and in marine construction.

� Auger PilesA feature of this pile is the flexibility of size (300 mm to 2 500 mm Ø), depth and speed of installation under ideal conditions of non-collapsing, dry soils. Casings may be used in difficult ground conditions.

� Underslurry PilesCommonly used where the soil profile is saturated, resulting in unstable side-wall conditions.

� Oscillator PilesOne of the most versatile pile types ideal for heavily loaded structures in adverse soil conditions.

� Continuous Flight Auger (CFA) PilesThis piling system is fast and economical. It has no vibration and limited noise levels associated with installation.

� Franki Forum Bored PileThis is a versatile pile type that is suited to sites that are congested, remote, have limited headroom or uncertain ground conditions.

� Full Displacement ScrewpilesThis piling system is fast and economical. It has no vibration and limited noise levels associated with it. It exhibits equivalent pile performance to a driven pile.

� RotapilesThis piling system has the ability to penetrate boulders, rock formations and socketing into hard rock.

� MicropilesMicropiles can be installed in limited access and headroom conditions. They can be installed with minimum disturbance to adjacent structures with the appropriate installation methodology.

Lateral SupportO

ur S

ervi

ces

� Soil NailsThis system is an in-situ soil reinforcing technique used to stabilise slopes or excavations.

� Post Stressed AnchorsFrequently used as tie backs to provide temporary or permanent lateral support to deep excavations, unstable slopes or similar.

� Franki Titan AnchorsAn innovative and versatile soil anchor solution in soft or very difficult ground conditions, where hole collapse renders conventional methods impractical.

� Concrete Soldier PilesProvide support either as cantilever walls, braced or tie-back walls, or to act as structural elements against which anchor forces are mobilised.

� Contiguous and Secant Pile WallsA row of concrete soldier piles installed to provide support either as cantilever walls or tie-back walls.

� Diaphragm WallsA reinforced concrete wall constructed in the ground using underslurry techniques, with widths of between 300 mm and 1 500 mm and to depths of 60 meters.

� Steel Sheet PilesEasiest and quickest way to form a retaining wall, in soft or loose saturated soil profiles.

� Pre-Cast Concrete Sheet PilesPre-cast concrete sheets interlock using the tongue and groove methodology. This is an alternative to steel sheet piles.

Ground Improvement

Near Shore Marine Works

Trenchless Technology

� Dynamic Consolidation and ReplacementInsitu compaction of soils to depths of up to 12 m, using pounders to impact high energy compaction.

� Vibro Compaction and Stone ColumnsThe Vibro Replacement technique builds load bearing columns made from gravel or crushed stones in cohesive soils and granular soils with high fines content.

� Jet GroutingMixing and partial replacement of the in-situ soil with cement slurry, which involves the injection of cement slurry into the voids in the soil.

� Deep Soil Mixing and Rigid InclusionsIn-situ strengthening of weak soils using binders or grouts to form columns of improved soil.

� Franki’s services extend to the design and construction of all elements of harbour work including dry docks, fixed or floating break-waters, jetties and quays for all sizes of craft, the construction of mooring dolphins and dredging or land reclamation.

� Refurbishment of old marine structures is also undertaken.

� Installation of concrete culverts and pipes up to 3 000 mm in size in almost any ground conditions.

� It entails manual excavation from within the protective confines of the jacking shield. The jacking shield is jacked forward using high performance hydraulic jacks and once the shield has progressed far enough forward, a concrete pipe is then lowered into position behind the shield. Excavation and jacking continues until sufficient pipe sections have been installed.
