pau wrap® OT

TDC’s pau wrap® OT was specially developed as a pipe protection solution against backfill materials for open trench installations. The factory-applied fibre reinforced composite has been engineered to withstand soil used for burying pipelines in rugged terrain, making it an ideal choice for projects that have particularly difficult geology, drainage issues, and steep right-of-way.

pau wrap® OT is a lightweight pipe protection product that mitigates the risk of damages during transportation, storage, the construction process and thereafter throughout the entire operating life of the pipeline. It provides protection against high impact loads, indentations, rock falls, gouging, and other abrasive conditions. As such, it eliminates the need for protective measures such as soil replacement or pipe protection mats, keeping the native soil and hydrology closer to their natural environmental state and minimising the foreign backfill substances used around the pipeline.

One of the key benefits of pau wrap® OT is its customisable design and flexibility, fully compatible with on-site cold bending, which is customarily used during the open trench pipeline construction process. This feature is a proprietary design characteristic specially made for open trench pau wrap® OT products. Depending on the pipeline project’s design and specifications, our engineering team works closely with the client to determine the final exact composition needed to meet the project’s individual requirements.
