SHalloduct
Engineered Frost Protection for Shallow Water Service Installations

SHalloduct provides an effective solution for protecting water pipes where standard burial depths cannot be achieved.
Whether navigating over rock formations, foundations, tree roots, or other obstacles, SHalloduct ensures your water pipes remain insulated and safeguarded against frost. Designed for both standard PE and barrier pipes of 25mm or 32mm diameter, it complies with and exceeds BS5422 and Water Regulation (4) standards, even under extreme weather conditions.
NB SHalloduct is the insulation that can be fitted inside a 94mm OD twin wall pipe (supplied by others).
