RENOVATION OF IDUSTRIAL CONSTRUCTIONS

Repairs and modernizations performed on constructions put in operation without interruption of the operation/production during works.

Protection and repair of building structures

  • repair of concrete and reinforced concrete structures by using technologies of PCC and SPCC reprofiling by manual or spray application
  • shotcrete – sprayed concrete
  • anticorrosive treatment and hydrophobization of concrete
  • strengthening structures with tapes and carbon fiber reinforced composites
  • strengthening and stitching masonry structures
  • application of specialist chemical resistant coatings for all types of loadings, e.g.
    • open tanks and sewers
    • process vessels
    • firefighting water tanks
    • tanks for drinking water, raw water and process water
    • closed pressure vessels and digestion chambers
  • execution of resin-based floors and pathways for all types of loadings
  • repair of industrial floors
  • waterproofing of foundations (mineral coatings, seamless and rolled bituminous etc.)
  • waterproofing of tanks (swimming pools, firefighting tanks etc.)
  • drying of buildings (basements, underground car parks etc.)

Repair and rehabilitation of sewer manholes and chambers, man-accessible sewers etc.

      • repair and rehabilitation of drainage manholes with trenchless methods
      • resetting manhole frames and covers
      • application of resin-based composites
      • trenchless rehabilitation of sewer systems
      • cleaning and TV inspections of existing installations

INJECTIONS IN GEOENGINEERING

Soil stabilization and consolidation by injection techniques:

      • stabilization of soil at the foundation structures (abutments, foundations, bottom slabs)
      • stabilization of floors
      • improvement of load-bearing capacity of soils – soli consolidation
      • filling voids and cavities – foundation underpinning
      • cut-off walls – anti-filtration barriers and removal of quick sand
