Method of Installation
SABAS Injection-moulded segments are jacked from an access point or located with a positioning trolley and jointed within the host-structure. For Type I linings, multi-piece segments can be longitudinally bonded within the host-structure; this ability can have major benefits for limited access situations.
Compounded, cemented or elastomeric radial joints are supplied as dictated by the geometry, application and specific project requirements. A SABAS designed ‘chocking-system’ is employed by the installer to ensure adequate restraint of the liner during grouting.
The annular gap is grouted with either 12 MPa structural grout, in the case of Type I composite systems, or 3 MPa non-structural grout in the case of Type II flexible lining systems. Additives are employed in the grout to ensure that good flow and anti-washout characteristics are achieved.
Following the reinstatement of entry and exit points, the completed system provides a fully renovated structure with a 50-year design life.Materials
