Advantages to using CRUX Grout Seal Systems • 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.
CRUX ECCENT Grout Seals for
pre-installed piles A special Grout Seal is available for structures with
pre-installed piles. Pile verticality and positioning tolerance dictates that
greater eccentricity may occur between pile and sleeves. The special Grout Seal
is designed to accept the increased annular dimension with provision of shape
allowing for extension.
CRUX TONGUE Seals for
drilled piles The Tongue Seal supports grout between a pile and a pile
sleeve on structures where the piles are installed by drilling. The Seal is
fitted on the pile prior to the pile being lowered into pre-drilled hole and
‘self activates’ as grout is injected. Two seals can be used for
greater pressure head. TONGUE Seals can
also be fitted to offshore windfarm structures
CRUX VULCAN Seals for
small pile sizes The VULCAN Seal has been developed and tested for use on
structures with relatively small pile sizes. The Seal is vulcanised onto the
Seal Can. The Seal Can is of similar size to the structure member (leg or
sleeve).
A single Seal can be used for limited pressure head (around 10 metres of grout)
but two or more Seals can be used for greater pressure head (detail shows two
Seals).
