Welcome to CRUX Products
Developing Innovative hardware for the installation of offshore wind turbine structures

Crux Products was incorporated in 1989 with the purpose of developing innovative ideas into highly reliable and cost effective products for use in the offshore installation of oil and gas production substructures.

One of our aims was to produce a reliable passive grout seal, used to support grout between piles and pile sleeves or structure legs. Since introduction, the Crux Grout Seal has been supplied for use in all oil and gas producing regions of the world, and has operated with unprecedented reliability over the complete range of pile sizes currently in use. As a passive system, opposed to the alternative inflatable active system, the Crux Grout Seal provides very clear cost and operational advantage.

With the advent of offshore wind turbine structures where the pile is pre- installed, there was a need for a large, very strong but flexible grout seal. In answer to this, Crux developed the Tongue Seal as a reliable and economical grout sealing method. The CRUX Tongue Seal has now become the industry standard for wind energy structures and has been used during the instalation of the worlds largest wind farms. The standard Crux Grout Seal is being used widely for Wind Energy jacket and tripod structures with post driven piles.
