Kemsolid BY KEMROC, a leading German brand in innovative rock cutting technology

Kemsolid by KEMROC is proud to announce the launch of two new models specifically engineered for railway and specialized foundation projects, focusing on shoring, sealing, separation, stabilization for high-speed applications, and the construction of retaining walls: ‘KSI Twin 16000’ equipped with 2 blades, and the ‘KSI Hydra equipped with advanced four-blades.

Building on this achievement, Kemsolid will present these groundbreaking models at the IGIC exhibition in the UAE on October 30-31, 2024, at Le Méridien Dubai Hotel & Conference Centre, where potential customers are invited to connect with the team and discover how these innovations can elevate their construction projects.

With extensive expertise in rock cutting, Kemsolid developed a unique soil stabilization process using its KSI excavator attachment, which injects and mixes concrete suspension into non-load-bearing soils to create a homogeneous, frost-resistant soil-cement structure. The new KSI models enhance this capability, while Kemsolid’s Trench Soil Mixing ‘TSM’ technology offers a modern alternative for shoring, sealing, and stabilizing soil, ensuring greater efficiency and reliability in soil improvement.

Alongside its global reach, Kemsolid has established a strong presence in Egypt, Saudi Arabia, the UAE, and other regional countries, with offices around the world distributing Kemsolid’s services tailored to meet specific market demands. The introduction of Kemsolid TSM technology is set to revolutionize soil stabilization and enhancement methods, improving construction efficiency in the UAE and Saudi Arabia while supporting the sustainable development goals of both countries.

In that regard, Mr. Gerd Maitschke, Global Business Development at Kemsolid, stated, “The introduction of these new models marks a significant step forward for the region, as Kemsolid delivers a powerful combination of speed and cost-efficiency for foundation and soil improvement projects with production rates of 1,000 to 1,200 sqm per shift—four times faster than traditional methods—making this launch a smart investment that offers streamlined project execution, cost reductions, and uncompromised quality.”
Additionally, Mr. Klaus Ertmer, Managing Director of Kemsolid & KEMROC, said, “With over 25 years of experience in developing cutting-edge excavator attachments, we are proud to introduce the ‘KSI Twin 16000’ and the ‘KSI Hydra’ models. Our deep understanding of the market’s needs has allowed us to design innovative attachments that enhance the versatility of excavators and address the specific challenges faced by the construction industry. These models reflect our long-standing commitment to providing solutions that meet the evolving demands of our customers and the industry as a whole.”

It is worth mentioning that Kemsolid has successfully completed numerous projects worldwide, including a recent one in Bay Minnette, Alabama. In this project, the Kemsolid KSI 12000, installed on a Hitachi excavator, was utilized for constructing soil-mixed walls for shoring with steel beams. The project involved building walls at various depths, ranging from 7 to 13 meters, in sandy and clay soils, covering approximately 29,000 square meters. This is just one example of the 40 solutions Kemsolid has delivered to major players in the foundation construction sector across countries like Japan, the USA, Egypt, Germany, Austria, Bulgaria, Poland, and Singapore.

KEMROC’s advanced drum cutters have arrived in the U.S., transforming the construction and excavation sector. 

KEMROC cutting-edge attachments convert excavators into high-efficiency rock trenchers, delivering up to 4x the productivity of traditional trenching methods. Known for precision, durability, and low maintenance, the KRC bullhead cutters feature unique angled drums that cut trenches to exact widths, perfect for trenching in medium to hard rock with cutting width from 600 mm up to unlimited trench width.

With a focus on sustainability and cost saving, KEMROC cutters also reduce fuel consumption by up to 40% and allow reuse of 75% of excavated material, cutting costs and emissions. In addition, KEMROC Bullhead cutters are low maintenance, needing only pick replacements and gear oil changes every 1,000 hours, making them ideal for contractors and rental companies. Contractors across the U.S. now have quick access to these innovative solutions through a network of dealers, enhancing project timelines, minimizing downtime, and boosting productivity on job sites.

A KEMROC KDS 30 diamond saw on a compact excavator cuts out concrete cable ducts from the floor of the tunnel to make room for a new tunnel lining.

The Elleringhauser Tunnel in Germany’s Hochsauerland region is being completely renovated. To install new tunnel lining, concrete cable ducts had to be removed from the bottom of the tunnel wall. Specialists from the EET consortium (Max Bögl/Marti DE/Marti CH) chose an 8-tonne compact excavator and a KEMROC KDS diamond saw to cut the concrete ducting into manageable pieces …

Using a Powertool KRX 70 drive unit with milling attachment, recesses are made in bored piles, into which reinforced concrete spurs are poured at a later date.

Near Osterode in the Harz Mountains (Germany), the intake section of the Söse dam is being renovated. In the process, the holding dam had to be resealed using a new bored pile wall. This wall is strengthened at the top and bottom with two reinforced concrete belts. To excavate recesses in the bored pile wall to attach the reinforced concrete spurs, Umwelttechnik & Wasserbau GmbH uses one of their own 24-tonne excavators with a KEMROC KRX 70 Powertool drive unit with longitudinal milling attachment. As a result, the project was completed within the required specifications and on schedule …

A KRC 140 Bullhead milling attachment excavates trenches in hard sedimentary rock to connect new elevated tanks to the drinking water grid.

In the district of Neundorf in the municipality of Rosenthal am Rennsteig, two new elevated tanks will supply water for the future. A large pit had to be excavated in bedrock before trenching for foundations and pipelaying could start. Mounted on a 26-tonne excavator, a KRC 140 Bullhead milling attachment from KEMROC completed all excavation work and trenching within expected tolerances and within expected timeframe …

To underpin a building, rock below the façade is carefully and precisely milled out by using a 25-tonne excavator with an EKT 100 drum cutter attachment.

To underpin a building in Paderborn, the construction company Karl Immig used a 25-tonne crawler excavator with a KEMROC EKT 100 rotary drum cutter. This was used to excavate rock from underneath a building with precision and with little vibration to create space for the necessary foundations. Thereafter the excavator-milling combination excavated trenches for services – and thanks to a 3D excavator grade control system, it was extremely fast and accurate …

A KEMROC KR 120 rotary drum cutter and an EK 40 chain cutter complete site preparation work efficiently and accurately.

The “Königsteiner Höfe” is a new residential and commercial quarter being constructed in the middle of Königstein im Taunus in the German state of Hesse. Acting as a subcontractor to the Köster Group, the company Höfling Erdbau was engaged to complete the site preparation work. Using two excavators with cutter attachments from KEMROC, the contractor put all the bored pile walls in place and put in the drainage systems efficiently and to the required accuracy …

At the Kassel sewage treatment plant, rainwater overflow basins are being replaced. The ring-shaped edge of the concrete basin is cut with a DMW 220 cutter wheel.

The city of Kassel in the German state of Hesse is gearing up for the future. At the sewage treatment plant, two aging stormwater overflow basins are being replaced by larger ones. To demolish the massive, ring-shaped concrete rims of the basins, the contractor Schnittger decided to use technology from KEMROC. Last year, a DMW 130 cutter wheel was used to demolish the rim of the first basin. This summer, a larger DMW 220 cutter wheel was used on the second basin to complete the work faster …

Prior to the construction of a large factory and warehouse, a KEMROC EKT 100 milling machine on a 25-tonne excavator is used to excavate trenches and pits for strip and individual footings.

At an industrial park at its hometown, Haiger in the German state of Hesse, the construction company Wirth secured a major contract. Before construction of a new factory and warehouse could start, they had to prepare the site and install foundations. A 25-tonne excavator with a KEMROC EKT 100 milling attachment was used to work out the footings through solid and fissured rock – saving time and money compared to the use of hammer and bucket.
