Description

We offer CFA-type earth drilling systems and related equipment : CFA-type couplings (adaptors), drilling reducers, earth drills, drill hangers, etc.

CFA drills are available in lengths from 2 metres up to the length you need. The most common drill bits used are 300, 400, 500, 600 mm in diameter. The drill bits are chosen according to the customer’s technique and the preference for drilling depths in 2 or 3 metre sections.

CFA drills are customised according to customer requirements. We assemble and connect on the customer’s equipment.

CFA stands for Continuous Flight Augers. This pile installation technology is very common in modern buildings because of its wide range of applications. To install these piles, special tools are used to drill the required diameter cavities, which are filled with concrete by pulling the drill back. CFA piles can be used in a wide range of situations, but they are most often used when the soil is very loose or when simple drilled or driven piles are not possible.

Prices vary according to the customer’s wishes and technical possibilities, but the system is many times cheaper than a self-propelled drilling machine.
