Fabric formworks can be used when existing pipelines have been subject to scouring or where the seabed profile under the pipeline has created excessive free-spans.

Fabric Formworks are envelopes which incorporate one or more grout injected nozzles. These are then inflated with the grout which when cured forms a permanent support under the pipeline.

The envelopes are made from reinforced woven polypropylene, are quick to install and can be deployed either by diver or ROV.

They can be used in conjunction with smaller grout sacks to give complete support, and solve your free-span permanently.

Pipeshield have a standard range of fabric formworks or we can manufacture bespoke designs to suit your requirements.
