A Bored Pile foundation is constructed by excavating or drilling soil, installing reinforcement steel bars and filling the drill hole with concrete material to form a pile. This method is also referred to as cast in situ method.
In general, this type of foundation is applied in areas where vibration and noise are not permitted such as in densely populated areas and in locations where there are many existing structures. This method is also applicable in conditions where driven pile is not able to penetrate hard layers or rocks within the soil strata.
The method commonly used for the execution of bored pile are:
- Temporary Casing (full or partial)
- Bentonite Slurry
PT. Berdikari Pondasi Perkasa has full a set of equipment to perform any kind of bored pile project. Our strong line of both mechanical and hydraulic drilling rigs are also complemented by auxiliary equipment such as vibratory hammers and bentonite plants, in order to provide our client with a complete and cost effective bored pile solution.
One of most common foundation types is driven pile. The piles are usually manufactured, then driven into the soil by one of the following types of equipment:
- Diesel Hammer
- Hydraulic Hammer
When noise and vibration do not present a problem to the surrounding area, driven pile is possibly the best solution for your foundation needs. It is also the most common method for offshore construction projects.
The material and dimension of driven pile are as follow:
- Steel Pipe Pile with a diameter of 300 mm to 1200 mm
- Concrete Square Pile with dimensions of 20 x 20 cm to 50 x50 cm
- Spun Pile with a diameter of 150 mm to 600 mm
PT. Berdikari Pondasi Perkasa has a proven record of performing driven pile projects, from small piles to steel pipe pile 1200 mm in diameter, both onshore and offshore. We have a complete range of diesel and hydraulic hammers to suit your pile driving requirements.
Another method of driving piles into the ground is the Pile Jacking method. This method employs a hydraulic clamp in which the pile is completely 'jacked' into the ground by using static force. This method has many advantages over the bore pile and conventional piling methods:
- There is no noise, vibration and pollution
- The project is left in a tidy and clean state
- It is much more efficient than any other pile driving method
- Quality is guaranteed as the driving process is similiar to that of a test pile
Pile Jacking is suitable for sensitive project sites such as within heavily urbanised areas (e.g. Jakarta City Centre) and in sites where existing buildings or utilities present a problem for other pile driving methods.
PT. Berdikari Pondasi Perkasa is introducing Pile Jacking Equipment with up to 800 tons end bearing capacity. The machine is able to pile up to 600 mm diameter pre-cast piles. Please contact us if you require more information.
Micro Piles is an advanced and delicate foundation technique which is particularly suitable in restricted area and limited space or where there are many existing structures, which prohibit conventional foundation technique.
Despite their small size (only 15 to 25 cm in diameter), micro piles are able to carry load up to 100 tons. They consist of steel bearing element which is placed into small diameter borehole and is later bonded to the ground by high pressure cement grouting carried out in several stages.
PT. Berdikari Pondasi Perkasa in the past has successfully implemented micro piles project in various projects with great success.
A Diaphragm Wall is a reinforced concrete retaining wall constructed at existing ground level and before bulk excavation. It is water tight and extremely stiff, and hence minimises any disturbance to the surroundings. It can also withstand high vertical load, and thus also function as a foundation. Diaphragm wall construction is an ideal method for construction of basements, dams, underpasses and tunnels among others.
Construction of diaphragm walls can be achieved through one of the following methods:
- Cast in situ method
- Pre cast method
PT. Berdikari Pondasi Perkasa, with its extensive equipment and years of experience is able to provide their clients with a quality and cost effective diaphragm wall solution for any kind of construction requirement.
Ground Anchor and Tie Rod/Waler are types of construction methods which are always used in conjunction with other type of construction methods. It can be utilised to provide extra strength for retaining wall type foundations or to provide extra tension capacity on conventional piles.
Once ground anchor is installed, tension process using hydraulic jack is then employed. PT. Berdikari Pondasi Perkasa has a complete solution package for providing materials for and installation of ground anchor and tie rod constructions to meet various client needs.
Sheet Piling is one type of construction method which is used for retaining wall purposes. The installation of sheet pile is usually done using vibratory hammer. The sheet pile is vibrated into the ground to the desired depth. Sometimes, depending on the soil type and the depth, sheet piles can also be installed using a piling hammers.
The main purposes of sheet pile construction are for shore protection and erosion prevention. It is also applicable for basement construction or as cofferdam.The most common material utilised for sheet piles are:
- Steel Sheet Pile
- Corrugated Concrete Sheet Pile (CCSP)
PT. Berdikari Pondasi Perkasa has a large range of vibratory hammers and piling hammers to perform any kind of sheet piling duties. Combined with our extensive line up of cranes and offshore equipment, PT. Berdikari Pondasi Perkasa is able to perform any kind of sheet piling project, whether onshore or offshore.
A loading test on pile foundations used to devise whether the loading of the pile is aligned with the initial design. There are many methods in which to conduct loading test. PT. Berdikari Pondasi Perkasa is able to propose and advise the most efficient and technically sound method.
PT. Berdikari Pondasi Perkasa has extensive experience and equipment to perform any type of loading test as required by our client, whether it be axial, lateral, compression or tension. We perform the test under the strictest condition in order to ensure the accuracy and reliability of the results.
Vibro floatation is commonly used to compact cohesionless soil, increasing its angle of internal friction, relative density and the elastic modulus of soil; thus increasing the shear strength.
A variation of vibro floatation method is to use gravel, which is then compacted to form stone columns. This method is utilised in soil with very low shear strength. In sandy soil conditions, vibro floatation and stone columns are ideal to prevent liquefaction in the event of earthquake.
With PT. Berdikari Pondasi Perkasa's extensive expertise on soil mechanics and our fleet of equipment, we are able to advise and provide solutions for any kind of soil improvement problems.
Vertical Drain is a construction method which accelerate the consolidation process of compressible cohesive soil, by draining the underground water vertically to ground level.
Vertical drain is a common method to be applied to new reclamation areas. The consolidation process can be expedited from years to only months, enabling the site to be faster developed.
PT. Berdikari Pondasi Perkasa provides a complete and cost effective Vertical drain program to satisfy client needs.
One of PT. Berdikari Pondasi Perkasa's main areas of expertise is the construction of jetty and offshore infrastructure such as: bridge foundations, shore protection and break waters. These projects are considered technically difficult and challenging.
