SLA® Barrier Pipe

Impermeable to protect potable water and the environment

The SLA® barrier pipe system reliably prevents the permeation of pollutants. The metallic permeation barrier enables permanent protection of sensitive media and the environment. In addition the electrical properties also provide the possibility of detecting the pipe and an integrity check after installation.

Product Structure | Installation techniques

  • permeation protection; even of trenchless installed pipelines
  • integrity test after trenchless installation as well as the possibility of permanent detection
  • open trench installation without sandbed, ploughing and milling, open installation in sandbed
  • black-box installations such as horizontal directional drilling, burstlining, relining and soil displacement
  • laying of pipe bundles with wastewater and potable water in one single-out route
