Leeuwanchor piles

Since the main qualities of Leeuwanchors, i.e. vibration-free installation and their high tensile capacity, are also featured in Leeuwanchor piles, it was obvious that the Leeuwanchor pile would also be introduced into the market once the Leeuwanchor had been launched.

The principle of this type of pile is identical to that of the anchor: a combination of screwing and injecting. The Leeuwanchor pile consists of a steel core and a grout body along its full height.

The piles can be installed in a wet environment to serve as foundations for underwater concrete floors.

LEKA piles

LEKA piles, developed by Van Leeuwen and Aannemings- en Funderingsbedrijf Kandt B.V., are soil-displacing screw injection piles with a permanent steel casing that are formed in the soil and that are installed using a vibration-free method. The tube is drilled to the right depth from the ground level. While drilling, grout can be injected along the pile shaft. Once the required level has been reached, the rebar, if any, is installed and the pile is filled with concrete. The cast screw head on the underside serves as a 'base' that prevents the pile from sinking and increases its load-carrying capacity. LEKA piles can be installed in locations where there is little room to work.

GEWI piles

These piles are formed in the soil. They feature a steel core that is encased by a grout body. The drilled hollow tube in which the pile is constructed is pulled out of the soil afterwards.

VF pile (Ariepaal)

The VF pile (Vibration Fluidization piles) is a patented GEWI pile. The casing of this pile is introduced into the soil by vibration in combination with fluidization within a short period of time. After placing the steel core, the casing is retracted while injecting grout on the outside, through the pipes. This enables the length of the grout column to be determined accurately and to reduce grout spillage.
