Solution & Construction Partner in Special Foundation Works
From largest bored piles to micro-piles – we are equipped for all pile foundation methods. Depending on the subsoil conditions we offer you several economically-efficient alternatives for heavily loaded foundations. Special Foundation improvement underneath existing buildings with limited working heights is available as well. Moreover we utilise our own inspection tools and we work out reliable optimisation concepts with the help of test piles
Grout injections
The subsoil can be improved by injecting various environmentally-compatible substances. This technique results in increased stability, mitigated settlement or reduced water permeability of the soil. Especially in the latter case, complex and lengthy water rights proceedings as well as high fees can be avoided, since the ground water is prevented from seeping into the building pit. As a leading company in the field of grouting ECC-LCC. Special Foundation Work contributes to the definition of consistent standards, even at European level.
Diaphragm walls
Diaphragm walls can be installed in close proximity to existing buildings serving – in combination with other methods – as solid retaining walls, as load-bearing foundation elements or as sealing against groundwater. Diaphragm walls are typically used in urban locations with difficult subsoil conditions or for landfill sites or complex infrastructure projects. To be able to meet various individual requirements our portfolio includes all diaphragm walling techniques.
Retaining walls
We offer several solutions for the construction of building pits where there is not enough space for a slope and watertightness is not the primary requirement. Depending on your demands we offer the following types of retaining walls: bored pile walls, , sheet pile walls, soldier pile walls, soil nail walls,reinforced concrete diaphragm walls, element walls, combi walls and more.
Anchor
Ground anchors are prestressed tension members made of steel strand or bar installed into mortared boreholes. They are used as temporary or permanent aids to transfer high tensile forces into the ground and in pit retaining walls, to protect buildings against groundwater uplift forces, to secure slopes or to transfer the reaction forces during pile test loading.
Micropiles
are piles of diameter generally smaller than 30cm executed with special technologies. Many times, micropile installation is chosen to the limitation imposed by extremely small working space and difficult working conditions.
