As a Company

Benefil Nederland BV:

The company with which we do our speciality jobs such as floor lifting and void filling.

Lifting sunken floors is a highly specialised job. We have highly trained personnel operating the foaming installation and laser levelling equipment to ensure it is done safely and accurately.

Void filling is a highly specialised task also, one can not simply ‘fill a void’ but they have to be aware of complications to the void’s surroundings before, during and after filling. Our team has many years of experience and also trains our dealer network worldwide.

Benefil’s History:

Benefil as a brand, was set up in 2004 as a collaboration between Aquaresins Technologies and Uretek Worldwide;

Uretek, specialists in lifting foundations and structures using PolyUrethanes; and Aquaresins, the manufacturer of aminoplast hardfoams, used for floor lifting and filling large voids.

In 2009, after years of close partnership, the owners of Aquaresins(based in The Netherlands) acquired Benefil Nederland from Uretek Nederland. We still work closely with dealers in the Uretek network across the rest of the world.
