Pile foundationFor a good foundation
Not all soil is equally suitable for the construction of buildings. If the upper soil layers do not have sufficient load-bearing capacity, this can be overcome by using pile foundations. The building loads are transferred to deeper, load-bearing layers with the aid of piles, also known as piles. The loads are transferred via the friction of the piles (skin friction) and via the contact area of the pile foot (point pressure).
Our experts determine the cross-section and length of the piles depending on the soil conditions and the size of the pile loads to be transferred. The material used for pile foundations also varies depending on the intended use, soil conditions and environmental conditions. Nägele Hoch- und Tiefbau primarily uses precast reinforced concrete piles and timber piles. In addition to conventional foundation measures, we also offer piling using ductile piles.
Ductile pilePressure and/or tension piles & energy piles
Ductile piles are used as foundation piles – they are a driven displacement pile system made of ductile cast iron. With working loads of up to 1,900 kN, ductile piles support almost all foundation measures and can be used for all structures as foundation piles, buoyancy control piles and slope and embankment stabilisation piles.
Wooden pilesBuilt on wood
Wooden piles are an economical and safe foundation method. Particular attention must be paid to the use of reinforced concrete caps. This ensures that the head of the wooden pile remains below the water table all year round. This guarantees long-term load-bearing behaviour.
The diverse areas of application for wooden piles.
- Industrial and commercial construction
- Pipeline construction
- Bridge construction
- Residential complexes
- Terraced houses
- Detached houses
Precast reinforced concrete pilesStability through reinforced concrete
Prefabricated reinforced concrete piles with individual lengths of up to 14 m are used to transfer high structural loads into the subsoil. If the prevailing soil conditions require longer piles for load transfer, several piles can be connected using couplings. Depending on the pile load, different cross-sections are used: 24 x 24 cm, 30 x 30 cm, 40 x 40 cm, DN35, DN45.
Your benefits when using precast reinforced concrete piles.
- Easy control of load-bearing capacity using pile driving formulas
- Continuous pile cross-section over the entire pile length
- No constrictions, no excess concrete consumption – especially in soft, mushy soils
- Different pile cross-sections enable optimum adaptation to the pile loads to be transferred
- Possibility of empty piling – piles are driven from the existing terrain, so no excavation is required in advance
