Technical information


The technical performance of ULTIBALAST can be engineered to meet ship or structure requirements. It is non-flammable and conforms to MARPOL and the IBC codes for toxicity.


Density Range = 1.5t/m3 up to 5.0 t/m3

Non-Magnetic options available up to 3.6t/m3

Density can be modified during installation.

ULTIBALLAST has been tested to establish a pH 12 rating.

Material strength classes are:

  • Fully Stiffened = 18 – 24N/mm2
  • Semi Stiffened = 12 – 18N/mm2
  • Non Stiffened = 5 – 12N/mm2

The residual moisture is typically less than 10% by weight after consolidation to a semi-solid like mass.

Through the migration of moisture to the surface, Ultiballast will settle into a homogeneous mass, reaching a maximum settlement of 0.3cm per 30cm depth.

Setting times usually between 8 and 12 hours, fully set and material strength achieved after 28 days.
