Meet the Experts in Drilling Consumables – Robit Blasting Team
A project is underway in Helsinki, Finland to build a completely new tram line, along with new municipal infrastructure and green spaces. The contractor Destia is using a wide range of Robit wear parts for soil and rock drilling in the project.
The alliance model project will involve the construction of approximately 4.5 kilometres of tramway and associated street areas and municipal engineering between Nihti and Pasila. The project will also include the renovation of street areas as well as improved pedestrian and cycling connections. Preconstruction started in Nihti in July 2021.
A massive groundwork project
An alliance group led by Destia is working in challenging street conditions in the middle of urban Kalasatama. The group’s share of the construction work on the new line comprises some three kilometres of road, the entire cross-section of which will be rebuilt in the course of the project.
“The section will be built on a pile slab structure, covering a total area of over 36,000 square meters, or about the size of five football pitches. During the project, about 100 kilometres of individual piles 15 to 20 meters in length will be used for road foundations,” says Alexei Kesonen, Project Manager for Foundation Engineering at Destia Oy.
At the same time, a ramp will be built for the possible future construction of a tunnel to Sörnäinen.
“The support structures of the ramp and tunnel walls combine three techniques: pipe pile wall, sheet pile wall and combi wall. Based on excavations, each was chosen to save time and, of course, to achieve a highquality result. The ground on the site varies widely from soft clay to hard rock to bouldery fill.”
“A wide variety of drilling equipment, sheet pile drivers and piling rigs are needed on site, allowing the choice of optimal working methods. With skilled workers, the right equipment and careful planning, even the largest projects can proceed on schedule,” says Kesonen.
Using domestic wear parts is an asset
Destia has a long history of solid cooperation with Robit on wear parts for soil and rock drilling.
“You can always trust the quality of Robit’s products and their service level as a domestic manufacturer. Speed of delivery is also excellent, which is an absolute must, as the schedules are tight, and work cannot stop because of missing parts. Robit supplies us with drilling consumables directly from their factory in Lempäälä. Of course, we also store them onsite, which ensures there is no downtime.”
“The pipe piles are installed using Robit’s 18″ DTH hammers, 508 mm SR XL2 ring bits, 508 mm SR pilots and L-model impact shoes, which arrive on site pre-welded to the pile ends. For the installation of combi wall piles, Robit Prime ring bits and pilots are used. For the supporting wall anchors, we are using Robit’s DT (Drill Through) technology, which allows us to drill the pilots into the rock through the ring bit assembly,” Kesonen says.
Construction of the new tramway line started in the summer of 2021. If all goes according to plan, the line will be operational by the end of 2024, greatly streamlining cross-town traffic: you can get from Kalasatama to Pasila by tram in 15 minutes. The route will also conveniently link trams to trains and the metro at several transport hubs.

One of the world’s largest construction projects is currently underway in Saudi Arabia near the northern end of the Red Sea. It is the future site of Neom, an ambitiously futuristic city planned to cover a total area of 26,500 km2 – more than twice the New York metropolitan area.
Still mostly on the drawing board, Neom is planned to comprise various high-profile regions, each catering to different needs. By late 2022, the plans for four regions have been publicized. Sindalah, a luxury island resort on the Red Sea, is expected to be the first physical showcase of Neom, scheduled to open in early 2024. Trojena will be a mountain destination for year-round skiing, while Oxagon is going to be a coastal clean industry hub.
The region that has attracted the most press coverage and provoked discussion worldwide, is called The Line. It is planned to consist of a single structure that is 500 m tall, 200 m wide – and no less than 170 km long, stretching from the Red Sea coast deep into the desert.
The Line is planned to house nine million residents, all with access to their basic services within a five-minute walking distance. Eliminating the need for cars, it is planned to use high-speed trains for transport within the city.
The transport system of The Line will consist of two separate railroads: one for the high-speed passenger trains and the other for freight services. The rail system will require the excavation of some 28 km of tunnels.
The tunnel construction bid was won by the Korean consortium of Hyundai E&C and Samsung C&T. The value of the order is estimated at no less than US$1 billion.
In the summer of 2022, the bidding for jumbo drilling and rock tools in the tunnel project was won by Jinyang R&S, one of the largest jumbo drill rental companies in Korea. Jinyang manages some 35 jumbo drill units, renting them with operators to tunneling and mining sites, mostly within South Korea.
Rock tools for the tunnel jumbos will be supplied by Robit. Since their distribution deal struck in 2017, Robit has supplied Jinyang with rock tools for several domestic job sites in Korea; the Neom deal, however, is unprecedented in scope.
“This is a huge project and a major deal for Robit for the coming years”, says Sales Manager Sunyong Choi of Robit.
At the future tunneling job site, the first test drillings using Robit’s tools started in November 2022. Still in its infancy, the entire Neom project is guaranteed to keep drawing widespread attention.

Hilla Niemelä is one of the rising young stars in Finnish skiing. A corporate supporter of sports, Robit signed a sponsorship and cooperation agreement with Hilla in late summer 2021.
The collaboration between Robit and Hilla is based on shared values and jointly produced media content that gives glimpses into Hilla’s training, racing career, goals, current affairs and future expectations. Hilla put the season opening update together:
The season has now progressed to the point that it is time for a little Christmas holiday. While this won’t really be a break from exercise, I will still have time to relax and recover at home and to prepare for my main objective for this season.
In May, I had to put practice on the backburner, when studying for the university entrance exams required a lot of energy. I did train even then, but in freeform, completely without a program and without stress. That same month, I also moved officially to Tampere, which has felt like the right choice ever since.
With the entrance exams over in June, I headed to Otepää for a training camp with my skiing club. And at the end of the month, I had this training season’s first U23 (Under 23) national training camp.
In July, I clocked over 100 hours of training. I had plenty of successful practice sets and even managed to break a few personal records during the test in the final days, despite considerable stress from all the training.
At the beginning of August, I attended yet another camp in Vuokatti, together with the U23 group. During that month, I also finally started my studies at Tampere University. All the studying for the entrance exams in the spring bore fruit as I managed to secure a study place, and now I am studying environment and biotechnology while training and competing.
I attended university regularly in September and October, but also managed to train a fair bit. At the end of October, I had a snow camp in Vuokatti and started accumulating the first skiing kilometers on snow.
November arrived with the start of the competition season at the Finnish Cup in Vuokatti. I got up to a good speed on both competition days and it started becoming evident that I was in good condition for competitions. The first races of the season have always been a bit more difficult for me, but I continued with a good flow at Olos the following weekend. Success at the high-level, traditional-style race on 10-kilometer distance guaranteed me a spot representing at the World Cup in Ruka. In a race in Taivalkoski, one week after Olos, I secured a spot for the sprint race in Ruka as well.
My first World Cup weekend started well, and I made it all the way to the Quarter Finals, finishing as 25th. I was also happy with my results in the 10-kilometer traditional race in Ruka. These successes gave me the opportunity to participate in the World Cup in Lillehammer in the 20-kilometer, traditional-style mass-start race. I had a couple of peaceful days at home after Ruka, before heading off to Lillehammer, where I had a clean race and loads of great experience. In the final listings I was 37th.
Having participated in races five weekends in a row, I was in dire need of a training break after Lillehammer. For me, this means a weekend without a race to attend to. After the training break I headed to Östersund for Scandinavia Cup, which is in practice a B-Class World Cup. I reached the 6th place in the qualification round of the traditional-style sprint, meaning that in the Quarter Finals I was up against the Olympic winner of last winter’s sprint, among others. High performance in the Quarter Finals netted me a spot in the Semi Finals with a lucky loser time, and there I achieved the 11th place in the final rankings.
Now I have some time to rest and recover again, gaining some energy from Christmas food. The next important races are in January of 2023. The plan is to head over to the United States at the start of January, in order to participate in the Winter Universiade, or the World Championship for students, in Lake Placid. The competitions will run for a couple of weeks, after which I will transfer from the US directly to Canada. This is where my main competition for the season, the U23 World Championship, will be held. I am now in a better condition than ever before and I am eagerly looking forward to finding out, just how far that will get me this year.
Best Regards, Hilla
