CRUX Grout Seals
and Mud-Exclusion Diaphragms

The CRUX Grout Seal is a passive grout support system, requiring no activation. The action of pile installation through the Grout Seal sets up a hoop tension in the reinforced bulbous ring. The resultant radial reaction of the bulbous ring acting against the pile, associated with the hoop tension, then counteracts the grout pressure forces. This system offers many clear advantages over the inflatable packer systems.

Mud-Exclusion Diaphragms are used to prevent seabed material from entering the annulus between the pile and pile sleeve or structure leg prior to pile insertion.
This type of Diaphragm is used in conjunction with Grout Seals where there are soft seabed conditions, such as encountered in the Gulf of Mexico. The combined action of the Mud-Exclusion Diaphragm and Grout Seal ensures that no seabed material ever enters the annulus.
