Installation of road barriers is one of the main activities in our company with more than 15-year history. In the beginning, we installed traffic barriers according to the client's specification (especially products of Arcellor Mittal). Since 2007 when the company launched its own type of road barriers (bridge barrier MS4/H2 and bridge railings crash barriers ZMS4/H2 and ZMS4/H3), we have prioritized OMO road barriers because of their excellent technical parameters for intended applications (bridges, along roadsides, retaining walls, etc.).

We supply and install road barriers not only in the Czech Republic, but also along the roads in the Slovak Republic and EU member states where they have the appropriate approvals and homologation. We act as subcontractors for big construction companies such as SKANSKA, EUROVIA, STRABAG, PORR, METROSTAV, COLAS CZ, SWIETELSKY stavební, OHL ŽS and HOCHTIEF, but also as a contractor to road owners, i.e. the state, county, city or private entities.

Drilling is performed using diamond core bits of high quality. Because core bits are routinely cooled by the water, the technology is virtually dust-free.

Core drilling of materials by OMO Stavby - key data:

• diameters from 10 mm to 1000 mm
• practical experience with drill holes up to 12 m deep
• drilling at precisely set angles in horizontal or vertical planes (i.e. in floors, walls, ceilings)
• electric or hydraulic drills
• drilling into various kinds of building materials - concrete, reinforced concrete, stone, various kinds of masonry, wall and floor tiles and material combinations
• upon request, we will arrange for structural analysis, required measurements

Resin-based anchoring systems

are comprised of an anchor - mostly a threaded rod of appropriate strength parameters - and resin-based grout that fixes the anchor in the hole.
Anchors – we use either own proprietary certified threaded rods (strength class 5.6), anchors from reputable manufacturers (e.g. Hilti) or other anchors requested by the customer (various bars, rods, hooks, and other anchoring systems).
Anchor putty – we mostly use Hilti systems or systems according to customer’s requirements and structural calculations.

Cement-based anchoring systems

Probably the most economical anchorage option. It consists of the anchor proper and anchoring grout, which is polymer-modified mortar (e.g. Groutex products).

Diamond wire sawing is a modern and cost-effective technology for cutting and removing large sections of concrete structures. Using a system of suitably positioned and attached pulleys, an electrical unit drives a special high-strength cable fitted with beads with diamond grit through the structure to be cut.

Diamond wire sawing by OMO Stavby - key data:

• virtually unlimited cut depth and area
• cut length according to client requirements
• precision cuts with relatively smooth walls (with possibly minor irregularities caused by the cable)
• cutting at precisely set angles in horizontal or vertical planes
• different kinds of building materials

It is an alternative to traditional demolition techniques using hand-held demolition hammers or large demolition machines. It is a more friendly technology for the immediate surroundings (eliminates shocks to the substrate material that might cause structural instability of nearby structures), and enables demolitions in places inaccessible to a large demolition equipment.

Hydraulic splitting by OMO Stavby - key data:

• maximum achievable force - 2800 kN
• area treated- no limitations
• depth of the structure – also no limitations thanks to the gradual breaking up of material
