Composite material with the look and feel of natural stone.
For kitchen and bathroom countertops, wall cladding and other furniture applications.
A premium stone-like surface without the complexity and cost of stone.
A deep, natural stone pattern that pairs beautifully with natural oak. To the touch it feels like stone, not like a coated board.
It does not absorb water, stains or dirt. Even fully submerged it keeps its appearance and stays solid — like stone.
Solid material through its full thickness. Years later, scratches and damage are sanded and polished out without removing the worktop. The surface looks new again.
The material is not brittle, so it does not crack or chip. Edges and corners stay intact even where life happens every day.
Cutting, drilling, sanding and CNC machining on ordinary joinery machines. Fewer complications in fabrication mean shorter lead times and a lower final price.
Grunor is made from 80 % recovered waste material and is designed to be reprocessed into new material.

Grunor can be cut, drilled, screwed, sanded and CNC-machined using standard woodworking equipment. No water cooling, diamond tooling or dedicated workspace required.
Cutting, drilling, screwing, sanding and CNC machining with standard joinery tools. The mineral in the composition is chosen so that it is no harder than tool steel.
The material bonds easily using a suitable two-component adhesive. Joints stay tight, waterproof and invisible.
Sand the surface and edges with a hand sander in three steps: grit 120, then 600, then a G2000 or G4000 polishing pad.

Our vision is to turn waste raw materials into useful, high-quality materials. Grunor is made from 80 % recovered waste and is designed to be reprocessed into new material, closing the loop.
Not because it is expected of us, but because we believe sustainability is a property of an advanced future.
