Spun concrete piles are manufactured in a well organized and controlled factory, Hence uniform quality can be obtained

Using High strength concrete of 60-80 N/mmi together with spinning process and the effect of prestressing in the concrete improve the structural strength of piles and other special features:

• High axial load capacity
• High tensile capacity
• Large bending moment
• Prevents cracking in the pile
• High resistance to sulphate attack and steel reinforcement corrosion
• Absence of torsional stresses induced during driving
• Enables the piles to be driven through hard strata

Spun concrete piles can be manufactured in longer length of 36m. Fast, economical and easy splicing, low unit weight hence lower cost. High rate of production, high early strength enable the quick delivery of the piles.
