Concrete paving blocks

Impeccable aesthetics

High-quality surfaces and large product variety

You need a mixer that allows you to produce high-quality surfaces and reduce the number of rejects? We have the answer! When it comes to producing paving stones, rely on the twin-shaft batch mixer (DKX). After all, it is particularly important for the top layer that structural additives and colors are mixed to perfection.

Benefits at a glance:

  • Twin-shaft batch mixer based on proven technology
  • Delivers a consistently high level of homogeneity in a short time
  • Partial batches as low as 10% of the nominal filling level
  • Low operating costs

Improved quality – Fewer rejects


Improved quality – Fewer rejects

The driveway and parking lot are often the first things you notice when making a house call. It is therefore no wonder that many companies and homeowners attach importance to attractive pavements. In the production of concrete paving stones, aesthetics are just as important as functionality. The proven three-dimensional mixing principle developed by BHS reduces optical defects to a minimum, resulting in fewer rejects and more satisfied customers.

The pressure is on to make your mixer shine


The pressure is on to make your mixer shine

For the production of concrete blocks, we recommend a mixer equipped with an integrated high-pressure cleaning system. Uncomplicated cleaning between two batches with different formulations virtually eliminates carryover. This reduces the number of rejects and guarantees reproducible results. Further optional equipment: adapted speed, precise moisture measurement and water metering as well as smooth mixing tools.

Success stories

More valuable fine sand from limestone

October 2021
No naturally formed rock is as versatile as limestone. Thanks to the high-performance crushing technology from BHS-Sonthofen, the French Colas-Group achieves high reduction ratio and excellent particle shape during sand mining.

More concrete paving blocks with less waste

September 2021
Excluton in the Netherlands expanded its capacity: Based on positive experience with the BHS twin-shaft batch mixer, one of the leading manufacturers of concrete paving stones again decided in favor of BHS-Sonthofen. Back in 2017, the company had already succeeded in producing significantly greater quantities of paving blocks within the same time while also reducing waste.

Complex concrete for dynamic projects in Paris

July 2021
The banks of the Seine river are home to Unibéton, an expert in liquid building materials. In Issy-les-Moulineaux, not far from the centre of Paris, the company produces a wide variety of concrete mixes on its 4,800 square meter site – from lightweight and high-performance to fibre concrete. In total, Unibéton manufactures around 2,000 formulations, especially for dynamic construction projects in Western Paris. Its machine park boasts some of the finest gear available – including a twin-shaft batch mixer of DKXS 4.50 from BHS-Sonthofen.

Mixing plants in use for concrete dams in Morocco and Cameroon

June 2021
International customers such as SGTM and the Nachtigal Hydro Power Company (NHPC) rely on mixing plants from BHS-Sonthofen for their concrete dam projects. The mixers used in Morocco and Cameroon continuously produce large quantities of RCC (Roller Compacted Concrete) to ensure completion of the infrastructure-relevant dam projects.

Concrete for Monaco’s land reclamation project

May 2021
Mareterra, formerly known as Portier Cove, is a major construction project, further extending the landmass of the principality of Monaco. EMT, Monaco’s only ready-mixed concrete producer and the supplier for the construction site, has installed a concrete plant from EMCI including a built-in twin-shaft batch mixer of type DKXS 3.00.

Caribbean sand: Company in the Dominican Republic uses crushing technology from BHS-Sonthofen

February 2021
Even in countries with large quantities of naturally occurring sand, manufacturing high-quality building materials is a challenge. Because this sand does not always have the properties required of a building material. On top of that, Dominican building materials manufacturer Calizamar, S.A. has set itself the target of meeting its customers’ demand for flawless building materials. The demand for fine sand to manufacture dry mortar and concrete in particular has risen continuously in recent times. Calizamar is using crushing technology from BHS-Sonthofen to fulfil its promise.

BHS mixer produces concrete for new hospital in Denmark

January 2021
DK Beton, one of the largest ready-mixed concrete suppliers in Denmark, was commissioned with supplying concrete for the Nyt Hospital Nordsjælland (New North Zealand Hospital) construction project in Denmark. In order to be able to supply 70,000 m³ of concrete over three years, it was decided to replace the existing concrete mixing plant in Farum. Our Danish partner CPT A/S was put in charge of planning and constructing the new plant. They selected a twin-shaft batch mixer DKX 3.0 with a new platform, new scales and a Walter cleaning system as the core component of the new facility. The customer is highly satisfied with the increased capacity as well as the longevity of this proven BHS mixer.

New mixer for NB Beton in Denmark

January 2021
A newly installed mixer from BHS-Sonthofen delivers high-quality concrete for NB Beton, a Danish concrete manufacturer with over 25 years of experience in the construction industry. The twin-shaft batch mixer DKX 3.0 is part of a new plant designed and built by BHS’ Danish partner CPT A/S. The construction site is located in Ejby, in the northwestern part of Funen island situated in southern Denmark.

Twin-shaft batch mixer used for construction of Tesla Gigafactory in Grünheide

September 2020
On Germany's most impressive construction site in Grünheide, Brandenburg, the US company Tesla is building its latest gigafactory for electric cars. The project worth several billion euros is to be completed in record time, with the first electric cars rolling off the assembly line as early as summer 2021. The construction of this gigantic factory requires huge amounts of concrete. To guarantee the required quantity, the plant operators involved also rely on high-performance mixers from BHS-Sonthofen. But what if a spare part is needed for these mixers? Every second counts in a case like this.

Twin-shaft batch mixers for Vietnam’s first offshore windfarm project

August 2020
Bac Liêu Province Wind Power Plant in Vietnam is Asia’s first large-scale coastal wind energy project. Operating since 2013, it is being expanded continuously. During the current third expansion phase, 71 turbines are being constructed. The challenge of this project can literally be found at the bottom of the sea: the cement bases for the wind turbines cannot simply be produced on land and then placed in the ocean. Instead, they have to be poured directly into the ground, using a floating platform. To this end, a mobile batching plant was installed on a dredge. At its heart are two twin-shaft batch mixers from BHS.
