Part of České Budějovice Bypass Finished

The South Bohemian metropolis is chronically overloaded with transit traffic, so any new road that has the potential to relieve České Budějovice, is only welcomed. This is also true of the so-called South Tangent (road II/143), which connects the existing I/3 road with the construction of the city section of the D3 motorway. The nearly three-kilometre-long link, whose investor is the South Bohemia Region, is being completed these days by a consortium of Colas CZ and FIRESTA-Fišer.


Construction Start Ceremony of Lešná - Palačov

In the presence of the Minister of Transport Martin Kupka and the Director General of ŘSD Radek Mátl, we have ceremonially started the construction of the road I/35 Lešná - Palačov.


Tramway line Ohrada - Palmovka

From March 2022, the tramway line Ohrada - Krejcárek was closed for reconstruction and passengers had to take alternative buses. However, the fast connection between Žižkov and Libeň on rails was re-opened this June. The complete reconstruction of the tramway link, which was carried out by a consortium of Colas CZ, a.s. and FIRESTA-Fišer and whose investor was the Prague Public Transit Company (DPP), is now fully functional.

Projects

We specialize in road construction, focusing on construction, refurbishment, rehabilitation and other works on roads and bridge structures. We also build and refurbish utility networks and infrastructure for trains and trams.

Road Construction

More

We construct, refurbish and rehabilitate various types of roads - from motorways, major roads, urban and suburban roads; to cycle paths, field and forest roads or even footpaths. In addition, we specialise in sports grounds projects and paved areas such as public car parks and parking areas, shopping centre car parks, paved areas in industrial zones, etc. Our portfolio also includes the construction and refurbishment of water management networks or environmental projects.

Railway & Tramway Construction

More

We perform construction and rehabilitation works both on railway and tramway projects, including works on the railway track substructure and superstructure and related structures such as bridges, culverts or platforms. In co-operation with our partners, we also deliver catenary equipment or signalling and communication systems for railway and tramway transport.

Bridges & Concrete Structures

More

We construct, refurbish and modernise road as well as railway bridge structures. Focusing particularly on bridges with a medium span up to 100 m, our scope of projects includes mainly RC bridges, pre-stressed concrete bridges, pre-cast concrete bridges and steel-concrete composite bridges. We also build wooden structures. In addition, we deliver projects of retaining walls, utility tunnels and various tanks, basins and structures made of waterproof concrete.

 

Products

We operate a network of 12 hot asphalt mixing plants (HAMPs) and 12 quarries, which allows us to supply construction sites throughout the Czech Republic. We offer a full range of aggregates, hot mix asphalts and polymer-modified asphalts (produced by our ASTECH plant).

 

Quarries

We produce crushed aggregates and sell quarried aggregates. We supply material for concrete batching plants, precast concrete plants, HAMPs, road and railway construction projects and water management projects. We also have five mixing centres to produce wet-mix macadam. We can also arrange transport of aggregates to construction sites. In selected quarries we can even load the material in railway freight wagons.

Hot asphalt mixing plants

We operate modern and efficient hot asphalt mixing plants (HAMPs) with an annual production output of about 700,000 tons of hot mix asphalt. In addition to traditional mixes, we can offer asphalt mixes developed in the laboratory of the COLAS Group in France. Our facilities undergo a regular modernization and upgrade to make production more efficient and environmentally friendly. Our ASTECH production plant in Holubice near Brno uses state-of-the-art technology in the field of polymer-modified bitumen to increase the quality and ensure a highly reliable supply of our products.

Our journey

Everything you might have not known about our company from its beginning

COLAS CZ, a.s. entered the Czech road construction market in 1994 as a merger of three traditional companies - Silnice Jihlava, Silnice Znojmo and Silniční stavitelství Praha. Gradually, COLAS grew its business in the Czech Republic and integrated many other construction companies. In 2008, COLAS acquired ASTECH, a specialist in polymers of modified bitumen, and since 2014 it has held a majority share in Silnice Horšovský Týn, s.r.o.

In 2020, COLAS purchased the at-that-time family-owned company Silnice Žáček, s.r.o., a strong regional player.
