The Aarsleff Tube consists of acid-proof polyester fibre impregnated with resin.

Aarsleff CIPP lining normally takes place without any excavations at all and is therefore suitable for rehabilitation of laterals.

A tube in soft condition is inverted into the defect lateral from the entry manhole. The inversion is executed with air and when the tube is in place and cured it has become hard and abrasion-resistant.
