Anti-Scour Mattress

Scour can occur in a suprisingly short amount of time. In fast running waters with granual soild, excessive scour can create serious structural voids, leading to excessive free spans, excessive pile exposure or other structural problems.

Pipeshield have developed Anti Scour Fronded Bi-Flex Mattress to combat this problem. These frond mattresses interupt and reduce the velocity of the near bottom current. Transported sediment drops out due to the reduced velocity and builds up to form an enbankment on and around the mattress.

Embankments can be formed in excess of one metre high, in some cases within a few weeks of installation. Pipes and cables are not protected from scour effects, but the enbankment enhances the protection and stabilisation and even permits marine life to colonise the final bank.
