PVC Waterstop - SikaFuko® VT-1

Re-injectable hose for sealing construction joints

SikaFuko® VT-1 is a re-injectable hose for sealing various construction and connection joints in watertight concrete structures. To seal the joint, SikaFuko® VT-1 is injected with suitable Sika® Injection materials, such as acrylate and microfine cement suspensions (for multiple injections) or polyurethane and epoxy resins (for single injection). With the integrated ‘valve techniques’ the hose can be used to re-inject multiple times if necessary.

  • Uses unique ‘valve techniques’ for injection
  • Multiple re-injections with Sika injection acrylate resins or microfine cement suspensions
  • One-time injectable with Sika injection polyurethane and epoxy resins
  • Easy and secure installation
  • Tested in water pressures up to 10 bar (328ft)
  • External test reports for suitable injection material
  • Ideal back-up system in combination with waterstops
  • Long-term references on many international projects

Usage

  • Sealing construction and connection joints
  • Suitable for many different structures and construction methods where additional joint security/safety is required
  • Prevents water ingress through concrete joints in the following typical structures: Water retaining or excluding structures, water reservoirs, dams, canals, sewage treatment plants, tunnels, subways, retaining walls
  • As a back-up system for waterstops
  • Enables testing for water leaks
