The structural and surface strengths of FIBREsheet overcome problems inherent with concrete, including its porosity and its inclination to movement and damage from hand tools, mechanical processes and general wear. FIBREsheet will resist chemical attack from acids, alkalis and solvents, giving complete protection from corrosion. |
Due to its tank-within-a-tank construction, the material is especially valuable in protecting concrete that is underground, and where hydrostatic pressure tends to delaminate conventional coatings.

A particular benefit of FIBREsheet is its ability to give effective protection in the area between steel pipes and their supports where damaging movement frequently occurs, causing serious abrasion. Water trapped in these areas inevitably leads to a highly corrosive situation. FIBREsheet, because it is flexible and easy to wrap, can shield both pipe and support. |

FIBREsheet provides a seamless, immensely flexible, glass reinforced, chemically resistant, easy-to-install, protective resin shield for pipes of every kind, including pipes underground. Its uniquely tough, translucent surface, once installed, does not dry out or crack, withstands abrasion, and is generally unaffected by stones and gravel pressed into it by vehicles passing above. Hence, pipes shielded by FIBREsheet are unaffected by water or chemical attack on the steel. |

| In the photograph, FIBREsheet is seen applied to pipe work at Paktank, in the Netherlands. Here the strength of the pipe wall was judged to be sufficient but a risk of leakage in the future was recognised. Plates could have been welded to the affected parts but, with the pipeline in constant use, this would have required down time. |

FIBREsheet was chosen to rebuild the thickness of the pipe and to prevent further erosion of the pipe wall. Throughout the application, the pipeline stayed active!

In the container ship seen in this picture, years of salt air circulating through the galvanised steel channels had almost completely destroyed the metal sheeting. FIBREsheet was wrapped around the outside of the corroded channels and cured in situ while at sea! The metal of the installation will continue to corrode and probably disappear. But the FIBREsheet will remain, maintaining a strong GRP channel that is not affected by the sea environment. |

Because FIBREsheet stays firmly in place, there are no cracks and no opening of seals through mechanical damage or thermal expansion. Once the material is installed, there is no parting at the seams.
| This effectively prevents water and chemicals penetrating thereby causing corrosion to the steel, and creating potential fire hazards. In these and other respects the material is superior to metal jacketing. |

Another of the many reasons why FIBREsheet was specified on Nedlloyd ships, the crew can walk, clamber and climb all over the steamlines and other pipe work throughout the length of the ship without damaging the stable, strong, protective material. With technical guidance, the ships crews were able to carry out a satisfactory installation.
