Company Announcement - Designed to endure the physical and thermal shock common to the marine environment, the new chocking/grouting compound is specifically formulated to spread out evenly across irregular surfaces. More importantly, unlike similar liquid applied chocking systems, Belzona 7111 can be stored and has currently been tested to confirm a three year shelf life. The recommended shelf life is expected to increase to five years when the testing is concluded.

Belzona 7111 application demonstration

Belzona 7111 is reported to be ideal for pouring foundations for heavy ship propulsion systems and other heavy equipment where alignment and anchorage are essential.  Since machining of foundations is not required, the cost and time for machinery installation can be reduced significantly.

The system is 100% solids, therefore it will not shrink during cure and possesses self-levelling properties, facilitating quick and simple application. Excellent load bearing capability is demonstrated by a comparably high compressive strength. Tested in accordance with ASTM D695, compressive yield strength measures at 14930 psi (102.9 MPa) and compressive modulus at 5.75x105 psi (3964 MPa). Available in grey or orange, Belzona 7111 features high creep, corrosion and vibration resistance, ensuring lasting performance under various service conditions.

The American Bureau of Shipping has approved Belzona 7111 for marine applications such as chocking, backing and leveling in engines, pumps, generators, compressors, reduction gears, bearing blocks, crane rails and other machinery. Dr. Xi Chen, Belzona Vice President of Research and Development said, “This ABS approval is a significant testimony that Belzona 7111 meets the highest quality and performance standards set forth by the Marine Industry.” This material has also been approved to be used in constructions built under the Lloyd’s Register’s survey.

Belzona 7111 does not require hot work or specialist tools during application and once cured exhibits high load-bearing capacity while providing precise equipment alignment. The system dampens machine noise and vibration as well as prevents loosening of threaded bolts. Substantial marine and onshore projects utilising this newly introduced chocking system are currently being secured as a result of these application and in-service features.
