Precast Reinforced Concrete Piles

PKM has been producing high performance reinforced concrete piles for more than 40 years now. Our technical expertise in the field of pile manufacturing and design has made us the foremost brand in terms of quality and performance.

PKM standard precast reinforced concrete piles are designed and manufactured according to:

BS 80041986 - Foundation
BS 81101997 - Structural Use of Concrete
CP 1161969 - The Structural Use of Precast Concrete

PKM also manufacture RC piles to the following specifications:

JKR Design
MS 13142004
Customised Design(Special Design Piles)

We have a wealth of experience in this field due to the fact that PKM is specialised in precast RC piles since 1985. All our units are made with High Strength Concrete.

Specifications

Concrete

Design Criteria

PKM piles are designed to resist normal handling and driving stresses and to support the required loading when installed.

Pile Shoes

PKM piles are normally provided with flat ended M.S. plate or pointed shoe at the pile toe. However, client can specify various pile shoes to be provided in accordance with the individual driving / site soil conditions as follows:

Easy / Medium hard drivingFlat ended mild steel plate.
Very hard drivingMild steel plate pointed shoe.
For penetration into rock / limestoneK-Shoe or Oslo pointed shoe.

Lifting Points

To ensure minimum lifting stress, 2 mild steel lifting hooks are incorporated in the pile at 0.21 times the pile length from each end.

PKM Standard Piles

PKM Standard Piles are designed to be used for high loading applications such as for high-rise buildings and even for bridges.

PKM Standard Piles have the following qualities and advantages:-

Up to Grade 70 concrete. Higher concrete grades available upon request.
Able to resist high axial loadings.
Enables huge savings in overall cost due to the reduced pilecap dimensions and reduced piling numbers as a result of using high performance concrete.
Very good durability due to the high concrete grade.
Time savings due to fewer pile points as a result of the high load-bearing capacity of the Standard Piles.

Maximum Load Capacity

In accordance to BS 8004, maximum axial load = 0.276 fcu ● Ac + fs ● As

fcu = Concrete characteristic strength at 28 days
Ac = Net concrete area
fs = Permissible compressive stress for longitudinal bars
= 0.55 fy but not greater than 175N/mm²
fy = Steel characteristic yield strength
As = Steel area of the longitudinal bars
