• when the working height is limited, for example in existing buildings or in factory buildings under pipework, etc.; the sectional concrete pile is mainly used for industrial flooring;
• in places which are difficult to reach, for example inside an existing building or in a garden with a narrow access;
• in areas where loud vibrations from pile-driving are not permitted;
• where work has to be carried out at low vibration levels.

TECHNICAL INFORMATION ON SECTIONAL DRIVEN PILES:

General:

• Length of pile: depending on the depth of the bearing stratum;
• Raking piles: in general not used;
• Minimum working height: from approx. 3 m, depending on dimensions of the pile and the type of pile-driving rig required;
• Minimum access width: from 0.7 m, depending on the dimensions of the pile and the pile-driving rig required;
• Minimum access height: from 1.7 m, depending on the dimensions of the pile and the pile-driving rig required;
• Minimum distance from centre of pile to a wall: 400 mm or more, depending on the dimensions of the pile, the required type of machine and the working space available;
• Monitoring and testing: recording the set of the pile per number of blows.

Sectional concrete piles:

• Diameter of concrete pile sections: 230 mm, 280 mm, 310 mm, 350 mm;
• Grade of concrete: C30/37;
• Reinforcement: minimum longitudinal reinforcement 0.3%, FeB 500;
• Maximum bearing capacity 500 kN (in the above-mentioned standard dimensions); the pile does not resist tensile forces;
• The pile is built up of sections which are 1.5 m, 2 m or 3 m long;
• Weight of drop hammer: 400 kg to 2500 kg depending on the dimensions of the pile and type of soil.

Sectional tubular pile:

• Diameter of tubular sections: 133 mm, 168 mm, 219 mm;
• Grade of concrete: C30/37;
• Maximum bearing capacity 250 kN (in the above mentioned standard dimensions); the pile does not resist tensile forces;
• The pile is built up of sections which are 1.5 m or 2 m long;
• Other sizes are available on request;
• Weight of drop hammer: 400 kg to 2500 kg depending on the dimensions of the pile and type of soil.
