Foundation board XPS

BEWI’s foundation boards are used where there are exceptionally high requirements for compressive strength.

Ideal for eg railways and railway embankments

Manufactured in densities from XPS 300 to XPS 500. The qualities of the XPS makes it ideal to use for e.g. railways and railway embankments, airports, industrial floors, parking lots, sports facilities etc. where the requirements for compressive strength are high.

  • Insulation of courtyards and streets
  • Insulation of roads and ramps
  • Insulation of parking spaces
  • Insulation of water pipes and drains
  • Insulation of railways and railway yards
