Pull-in-place lining is a CIPP variant in which a resin-impregnated liner is winched through the host pipe between two access chambers and then inflated against the pipe wall using a calibration tube. It is typically used where inversion is not practical, for example on shorter sections, on pull-through patches or where access is restricted to one chamber. The method allows accurate positioning across defects and is well suited to spot or short-length repairs on London domestic drains. Curing is usually achieved by ambient resin or UV light, with works carried out in accordance with BS EN ISO 11296-4. Pull-in-place lining requires careful pre-cleaning of the host pipe so that the liner can slide without damaging the resin face.
