Special foundations & boreholes

A public health issue

The Duval Group, through its subsidiary Fondations et Forages d'Afrique, is involved in the water drilling business, in particular deep drilling (up to 500 metres) that allows the installation of drinking water supply networks in villages. These facilities provide African villages with clean drinking water, solving health problems associated with drinking unfiltered and untreated water.

Innovative solutions to soil problems

Our team of professionals responds to the problems of unstable, clayey, gravelly, marshy soils and the changing climatic effects associated with periods of severe droughts and heavy rainfall, wreaking havoc on all types of buildings. The technical department supports construction teams as well as our customers, upstream, starting at the project study phase but also during construction, by monitoring each phase. This local support allows the field teams to be highly responsive and adaptable to difficulties at the construction sites. For our customers, it ensures flawless performance and risk control, in compliance with contractual provisions.

Water drilling and deep drilling

Our Group is involved in the entire drilling cycle. FFA drills water wells and deep wells (up to 500 metres), and provides all the high value-added services related to well engineering. Our expertise, mastery of cutting-edge technological processes and full adherence to safety standards are appreciated by public and private institutions on the African continent, who renew their confidence year after year.

In addition to the technical, health and comfort advantages, village water supply also has an economic impact, including providing station managers a living as well as opening the way for other businesses that were previously impossible in village locations. The Group aims to offer a complete water service including drilling, pumping, filtration, storage and distribution through intelligent standpipes.

Geotechnics special foundations

We carry out soil studies (pressure meter, penetrometer, coring) as well as the installation and construction of piles for transport infrastructures and the construction of various buildings (Cameroon, Congo, Togo). The drilled piles are made by excavating materials and pouring concrete into the ground. The use of sludge (bentonite, polymer) ensures the soil's resistance during drilling operations.

Pipelines and water supply

To supply the population with water, the Group carries out piping and drinking water supply services. Water supply includes all the techniques used to bring water from its source to the places of consumption. The Group works with local authorities to distribute drinking water, renew pipes and connections and connect them to existing pipes. Qualified and experienced teams also offer the necessary know-how to carry out collective sanitation works.
