Fabric reinforced Grout Seals, manufactured as a concrete-filled ‘passive’ solution with none of the reliability issues surrounding inflatable options. Grout Seals, as a passive system (opposed to alternative inflatable active system) have become the product of choice due to their clear operational and cost advantage due to factors such as: No hoses, valves or other hardware to purchase, fit or test. This results in clear cost savings and eliminates the dominant cause of frequent grout support system failure No site testing or commissioning required The Grout Seal also functions as a wiper, preventing seabed material from entering the annulus to the detriment of grout connection strength No offshore operation is required No residual activation hardware remains to cause cathodic protection drain or diver hazard
