Tunneline is a one pass operation and requires no back grouting after the lining is installed, this has the added benefit of significant time and cost savings.
Tunneline is a stand alone structural element and as such the host structure acts as a back shutter, Tunneline does not require any advanced pre works or stabilization to the host, – voids, holes cracks or missing masonry does not need to be repaired prior to installation.
Tunneline can be constructed inside any existing man access structure regardless of shape, access or aspect, Tunneline can accommodate horizontal and vertical curves and can be designed to cater for changes and transitions in profile as well as significant deformation. Tunneline can be installed in vertical structures such as tanks and chambers as well as in horizontal elements.
Tunneline can be installed to recover the structural integrity of existing assets extending the life by 100 years and is suitable for any format of host ranging in size from 1200mm to 9000mm.
Tunneline is non-intrusive with access being gained from existing portals and man access chambers, surface intervention and disruption to traffic and the public is not required therefore delivering carbon savings over conventional construction replacement techniques.
