P400 injection system      

Inspection Report (in German)

Ever-greater importance is being attached to sealing concrete structures. Although construction joints are unavoidable in structural components for design and practical reasons, the damage that is often caused by moisture at such locations can be avoided. The extent of work and costs associated with remedial work are high. The growing awareness of quality and durability calls for new design solutions that guarantee long-term protection against penetration.

Application:Waterproofing construction joints P400 injection hose encased in bentonite, which swells on contact with water

P400 injection hose for injecting:
  • PUR resin
  • PUR foam
  • Epoxy resin
  • Acrylate gel

Allows multiple injection, e.g. with acrylate gel

  • Swells on contact with water
  • Initially no injection required as a general rule
  • Can be activated by filling hose with water
  • Resists penetration by foreign substances
  • Full surface contact
  • Ready-made in 5 m lengths
Sheath construction:
  • Sheath of swelling bentonite (based on natural clay) fully surrounding the hose
Injection hose construction:
  • Plasticized PVC injection hose with multiple functional features
  • Internal transportation channel surrounded by four secondary channels
  • Orifices in the form of micro-slots in linear arrangement with buffer zones to facilitate valve function
  • Duobox for connecting two hose ends; standard depth for concrete cover 30 mm
  • Nailed fitting
  • Hose end box
Hose mounting:
  • Betoquell levelling paste for gluing and levelling
  • FUMAX® contact adhesive
  • BETOFIX for gluing
