One of the major fields in which Colas CZ, a.s. is focused on are all the activites connected with road constructions – realisation, reconstruction and repairs of roads and motorways – and many more, including local roads, monolithic constructions and bridges. We are also building and reconstructing infrastructure systems (i.e. waterworks) and railways.More about Projects
Particularly, we construct motorways, highways, local roads and utilitarian roads, including its necessary reconstructions or repairs.
Our other road constructions include (but are not limited to) cycle paths, footpaths, car parks, sports venues, etc.
In co-operation with COLAS RAIL, we realise railway and tramway constructions. This teamwork leads to a beautiful synergy which leads to both on-surface and underground constructions of railways. During the process, we are able to build artificial constructions, bridges, culverts or platforms. Together with our partners, we can cover realisation of overhead lines or railway signalling and traffic control intended for railway, as well as road transportation.
We are building, reconstructing and repairing monolithic constructions and bridges intended both for road and railway transport. In addition, we are constructing wooden or metal footbridges and bridges, retaining walls, noise barriers, collectors and constructions made from water-resistant concrete.
The main focus is upon bridges with the span up to 100 m, namely monolithic, reinforced-concrete, prestressed, pre-fabricated, composite-steel, steel or wooden.
Our another matter of interest is operating in and independent test laboratory with expertise in the field of road construction. Our focus in set upon testing asphalt mixes and binders, soils, aggregates and both fresh and hardened concrete.
Moreover, we perform inspection testing of individual road constructions including its subgrade and measuring the surface properties of concrete or asphalt roads and pavements.
