Individual condition inspections & evaluations

As an accredited building materials test laboratory, VersuchsStollen Hagerbach AG offers individual condition inspections «à la carte», as well as custom itineraries for condition inspections.

At our facilities, we carry out inspections on concrete and reinforced concrete structures by means of:

  • Visual inspections
  • Percussive testing (tapping)
  • Locating reinforcement
  • Potential (field) measurement as per SIA MB 2006
  • Temperature measurements
  • Concrete strength measurement using a rebound hammer
  • Surface condition
  • Evenness testing 
  • Bond strength
  • Drill core extraction
  • Drilling dust extraction
  • Moisture measurement with CM measuring device
  • Probe openings

Laboratory tests on samples taken from the building:

  • Strength values
  • Elasticity modulus
  • Chloride content
  • Water absorption coefficient
  • Carbonation depth
  • Porosity
  • Hydraulic conductivity
  • Resistance to frost and de-icing salt
  • Chloride resistance
  • Sulphate resistance
