Breakthrough on the IPAL Piping Project Zone 1&3 KIPP IKN East Kalimantan has been successfully carried out again by the PT Tohoma Mandiri team. The SPAN that we successfully worked on was from Departure MH0179 to Arrival MH0178 and the span was 47 meters long with 47 pipes. This breakthrough is an important milestone that shows the success of the microtunneling jacking method.
This project is designed to support an efficient and sustainable wastewater treatment system in the KIPP-IKN area. The scope of our work is DN200mm microtunneling work using Microtunneling Boring Machine (MTBM) technology, which is a technique that is very suitable for infrastructure projects in dense areas.
Our commitment to optimal results through the application of the latest technology and structured project management is reflected in the success of this breakthrough. In addition, work safety is our main priority in achieving mutual success.

Bentonite is a natural clay with a fine and soft texture that has the ability to form lubricating mud, control ground water, seal boreholes, and increase soil stability making it an irreplaceable element in many aspects of construction. Bentonite contains the mineral montmorillonite which can be used in various fields, while the basic ingredient that forms bentonite stone is volcanic ash.
PT Tohoma Mandiri is present as the exclusive distributor of Baroid – Halliburton as well as chemicals which can be used in underground drilling processes. Our product range includes Bentonite TUNNEL-GEL, QUIK- GEL, Polymer EZ-MUD, etc. Our team of experts has a deep understanding so you can say you have a partner you can rely on. For further information, you can contact us at the contacts provided.

In the midst of rapid infrastructure development in Indonesia, technology continues to develop to meet project needs. One of them is jacking technology, especially microtunneling, which is the main concern of the Indonesian construction industry. This method is done by making a small tunnel using a drilling machine (Microtunneling Boring Machines, MTBM) combined with pipe jacking techniques.
This method does not require open excavation so it is suitable for urban areas and environmentally sensitive areas so this method is increasingly popular as a solution to reduce environmental impacts and avoid disturbance to the community. PT Tohoma Mandiri is a company providing microtunneling services which has a team of professional experts in this field, with extensive experience and expertise.
Jacking methods are divided into several types. PT Tohoma Mandiri focuses on implementing pipe jacking on the slurry type and auger type. The slurry type uses slurry to maintain drilling stability and the types of pipe that can be installed are RCP, RCCP and DCIP pipes with diameter variations of 450mm-1800mm. Meanwhile, the auger type uses a casing as a means of transmitting the thrust force and the pipes that can be installed are RCP pipe, PVC and clay pipe with a diameter of 200mm-300mm.

PT Tohoma Mandiri was selected as a sub-contractor in the Zone 1 and 3 Waste Water Treatment Plant project in the East Kalimantan Nusantara Capital Area with PT Wika – Hutama, KSO as the Main Contractor.
The waste water pipe installation work using the Jacking Auger Diameter 200 method has several challenges that need to be faced, including hard ground conditions, especially rocks in the form of shale mudstone. This condition has an impact on the daily productivity level of pipe installation.
However, with cooperation between professional and experienced teams, this challenge will be overcome well and always prioritize work health and safety so as to achieve optimal results.

We at PT Tohoma Mandiri are very aware of the seriousness of the problem of air pollution which has become an important issue recently. The impact not only threatens public health, but also places an additional burden on our vulnerable environment. Therefore, we have committed to being part of the solution.
In every project, we adopt innovative technologies such as microtunneling and separation plants. The aim is not only to ensure the efficiency of our work, but also to keep environmentally friendly aspects as a top priority. By using sophisticated underground drilling machines, we have succeeded in avoiding air pollution emissions that can damage our air quality, as well as keeping the environment clean and healthy.
Not only that, our separation system also plays a role in keeping hazardous materials under control and not polluting the surrounding environment. Together, we are united in supporting the ‘Zero Emission’ movement which is the key to a greener and more sustainable future.

Finally! Once again, PT Tohoma Mandiri succeeded in making a breakthrough using the Jacking Microtunneling method on the Makassar WWTP B1 Project, Makassar City Main Waste Water Channel Work Package. The SPAN with the Jongaya Canal crossing that we successfully completed from Departure MH10343 to Arrival MH10340 has a length of 150.66 meters with 62 pipes.
The Microtunneling Jacking method allows us to deal with various obstacles. This includes the drilling route passing under the Jongaya Canal, which is a densely populated area so we have to drill without having a negative impact on the environment. The entire process is also carried out carefully and meticulously, ensuring that each step is carried out optimally and in accordance with procedures.
PT Tohoma Mandiri has successfully undertaken a project aimed at enhancing wastewater management in the urban areas of Makassar City. Serving as a Sub-Contractor, we specialized in microtunneling DN1000mm, with strong support from PT PP as the Main Contractor. Together, we are committed to advancing sustainable infrastructure solutions for a cleaner and more efficient urban environment.
