Products and Services

TDC’s pau wrap® is a composite based mechanical protection system consisting of factory-applied coating for pipes and welded joint protection at the construction site. Its main function is to protect pipes from damages due to indentation from sharp objects (i.e. rocks, gravel or debris), abrasion from dragging the pipe (i.e. during trenchless installations) and from strong impacts (i.e. heavy backfill material).

The outstanding mechanical shear strength of TDC’s pau wrap® to the pipe and its anti-corrosion system makes the optimum solution when the normal coatings are not able to guarantee the integrity of the pipelines.

Three of our main pau wrap® products are:
- pau wrap® TL: Factory-applied line pipe coating for Trenchless installations
- pau wrap® OT: Factory-applied line pipe coating for Open Trench installations
- pau wrap® FJC: On-site field joint coating for Trenchless installations

pau wrap® OT

TDC’s factory-applied GRP line pipe open trench application, pau wrap® OT, serves as a mechanical protection layer to the anti-corrosion layer. It has been specifically designed to allow the pipe to be directly buried in rocky terrain in open trenches without the need for additional protective measures such as pipe protection mats or soil replacement, even in the case of coarse-grained excavated material or rocky subsoil.

pau wrap® TL

TDC’s factory-applied GRP line pipe trenchless application, pau wrap® TL, serves as a mechanical protection layer to the anti-corrosion layer. It offers extreme protection to abrasion, corrosion, temperature, physical force and chemicals, and can withstand harsh underground geological conditions.

Specifically designed for trenchless technologies, pau wrap® TL has been successfully used across all typical trenchless installation methods including HDD, Direct Pipe and micro-tunnelling.
