Bored Piles  Bored Pile foundation is constructed by excavating or drilling the soil, installing reinforcement steel bars and filling the drill hole with concrete material to form a pile. This method is also referred as cast in situ method.In general, this tupe of foundation is applied in heavily built up areas, in city areas, in location where there are many existing structure and in soil condition where driven pile is not able to penetrate hard layers within the soil. The dimension of bored pile ranging from diameter of 30 cm to 200 cm, with depth from 5 meter to 50 meter. The method commonly used for the execution of bored pile are:

Driven Piles One of most common foundation type is driven pile. The piles are usually manufactured, then driven into the soil by one of the following type of equipments:
The material and dimension of driven pile are as follow:

| Pile Jacking Another method of driving pile into the ground is by 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 bore pile and conventional piling method:
PT. Berdikari Pondasi Perkasa is introducing Pile Jacking Equipment up to 800 Tons end bearing capacity. The machine is able to pile up to 600 mm diameter Pre-Cast Pile. Please contact us if you require more information. Back |
| Micro Piles 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. Back |
Diaphragm Walls Diaphragm Wall is a reinforced concrete retaining wall constructed from existing ground level and before bulk excavation. It is water tight and extremely stiff, hence minimising disturbance to the surroundings. It can also withstand high vertical load, thus also able to function as foundation. Diaphragm wall construction is an ideal method for construction of basement, dam, underpass and tunnel among others.Construction of diaphragm walls can be achieved through one of the following ways:

| Ground Anchors Ground Anchor is one type of construction method which is used in conjuction with other type of construction. It can be utilised to provide extra strength for retaining wall type of 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 material, installing and stressing ground anchors as required by our clients. Back |
Sheet Piles 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 as required.Main purposes of sheet pile construction are for shore protection and erotion prevention. The most common material utilised for sheet piles are as follow:

| Vibro Floatation & Stone Columns Vibro Floatation is commonly used to densify cohesionless soil, increasing its angle of internal friction , relative density and the elasticic modulus of soil; thus increasing the shear strength of the soil. A variation of vibro floatation method is to use gravels, which is then compacted to form stone columns. This method is utilised in a soil with very low shear strength. In sandy soil condition, vibro floatation and stone columns is ideal to prevent liquefaction in the event of earthquake. With PT. Berdikari Pondasi Perkasa's extensive expertise on soil mechanics and our fleet of equipments, we are able to advise and provide solution for any kind of soil improvement problems. Back |
| Vertical Drain Vertical Drain is a construction method which accelerate the consolidation process of compressible cohesive soil, by draining the underground water vertically to the ground level. Vertical drain is a common method to be applied to new reclamation area. Consolidation process can be expedited from years to only months, enabling the site to be developed quicker. PT. Berdikari Pondasi Perkasa provides a complete and cost effective Vertical drain program as required by our client. Back |
| Loading Test Loading Test on pile foundation is a method to test 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 equipments to perform any type of loading test as required by our client, whether it is axial, lateral, compression or tension. We perform the test under the strictest condition in order to ensure the accuracy and reliability of the results. Back |
Offshore and Jetty Construction One of PT. Berdikari Pondasi Perkasa's main expertise is construction of jetty and any offshore infrastructure such as: bridges foundation, shore protection, break water among others. Projects which is considered as technically difficult and challenging. Our offshore fleet includes the following:
