The syntactic foam is typically cast into blocks and then used to prepare large buoyancy modules that can be readily shaped to conform to the buoyancy final design.

BMTI® has over 20 years of experience in syntactic foam production and particularly in the manufacturing of pure syntactic foam blocks.

Each parameter of standard syntactic foam block manufacturing (from raw material to finished product) is monitored, including traceability, throughout the manufacturing process. These checks are also recorded.

BMTI® includes a pressure test control on all products, where the pressure is monitored for 24 hours on a segment of each standard block.

The prices of our blocks are EX WORKS prices.

We can quote for you transport prices (standard or premium) for anywhere in the world, please send us a request.

We have a large stock of off-the-shelf standard buoyancy blocks, ready for immediate delivery.

In the case of custom-made orders, we will do our best to deliver within your time frame, taking into account your specific requirements.

We can calculate the number of blocks needed according to your design and upthrust objective, as to optimize the sketch and also offer the assembly of the sketch from standard blocks, according to your 3D drawings.
