Question
What is an injection hose system?
Expert Answer
An injection hose is a perforated tube installed in concrete construction joints before the concrete is poured. If a leak occurs later, resin can be injected through the hose from accessible entry points, traveling along the joint and sealing it from within. It is a 'maintainable' detail often required by BS 8102:2022 for Type B structures, providing a backup plan for joint failure without the need for destructive drilling.
