INTRODUCTION

ICP Pile is a high performance and high strength pretensioned spun concrete piles that are extensively used in large, complex and technically challenging projects – from high-rise buildings, marine structures to power stations.

ICP Pile comes in concrete Grade 80, Grade 90 and Grade 100 with lengths varying from 6m to 46m. It also comes in three classes based on the effective prestressed as specified by Malaysian Standard (MS 1314:Part 4:2004). Generally, its prestressed bars are made of high frequency heat-treated bars manufactured to JIS G 3137:1994 standards to ensure only the highest quality and strength.

ICP PILES ATTRIBUTES

High productivity enables immediate delivery to project sites.
Piles can be delivered as early as 3 days after casting.
Customizable to suit any project requirements.
Spinning process results in denser concrete, giving high resistance to corrosion.
High strength concrete of up to Grade 100 enables piles to be driven through hard strata, providing a more economical solution.

Can be manufactured up to diameter 1200mm and a maximum single length of 54m.
Big diameter piles can be joined in the factory up to the length of 90m.
Environmental-friendly installation which are noise, pollution and vibration-free using hydraulic jacking pile installing machine.
Prestressed concrete provides higher bending moment capacity compared to conventional reinforced concrete piles.

JOINT WELDING DETAILS

BONDING ICP PILES INTO PILE CAP

As the PC bars are bonded with concrete, ICP Piles may be cut off at any point. The piles need not be stripped down to expose the bars and can be bonded to the pile cap as shown in the below sketch. If the piles are not subjected to tensile load, the recommended H.T. bars are considered adequate.

PILE SHOE

ICP Piles can be supplied with various types of shoes upon request. Below are the most commonly used pile shoes that has been used with ICP Piles. ICP Piles can also be supplied open ended or with flat shoe when required.
