Amino-plastic resin (Benefil)
Low-pressure amino-plastic resin fills large and small voids, including annular spaces in pipelines.
We use an amino-plastic material called Benefil. It is a multi-purpose, super-lightweight or filler grout. This makes it a very economical void-fill material.
Benefil is easy to apply: it can be pumped, poured, or injected into voids, holes, and interstitial spaces. It can also be distributed downwards, upwards, or laterally and can also be pumped over very long distances, making site access problems a thing of the past.
Benefil is environment inert and even absorbs residual hydrocarbons.
While not intended to withstand point-loading or abrasion, Benefil can be produced in various densities to achieve compressive strength in accordance with load requirements.
Amino-plastic resins are environmentally inert and are bio-degradable in sunlight. Benefil is used extensively in horticultural and landscaping applications.
Benefil is also long-lasting. In typical engineering applications it does not decompose and it resists hydrocarbons, solvents, and other chemicals, for a life expectancy of up to 150 years. The product has been used in Europe for more than 30 years.
