The installation of headwall outfalls has been vastly optimised using the patented Permashutter Polymer headwall system.
The Headwall is now complete and requires no further visits
Permashutter provide a full range of headwall ancillaries
All ancillaries can be ordered with the headwall and are installed by locating into the pre configured positions prior to filling the headwall mould with concrete.
This enables a high quality installation with only one visit.
Our ancillaries may also be ordered separately for retrospective fitting to precast or cast in situ headwall units.
