Our Materials

Belgian natural stone from our own quarries.

Renier works with two types of Belgian natural stone: Belgian Blue Stone from La Préalle and Vinalmont Meuse Limestone from the Vinalmont quarry. These are two authentic materials, each with its own character, appearance, and technical qualities.

Belgian-owned quarries

Two quarries, two materials, one short supply chain.

By working with our own quarries, we ensure quality from the source to the finished product. The stone is quarried locally, processed in our own facilities, and finished according to its intended use.

Belgian Blue Stone

Sturdy, timeless, and quintessentially Belgian.

Belgian Blue Stone is one of Belgium’s best-known natural stones. The material is characterized by its blue-gray color, compact structure, and the presence of natural fossils and veins.

This stone is exceptionally versatile. It is used for door sills, window sills, facade base courses, stairs, floors, coping stones, pool coping, and numerous custom applications.

Thanks to its strength, frost resistance, and long lifespan, Belgian Blue Bluestone is suitable for both classical and contemporary architecture.

In-house production

From raw block to finished custom piece.

Renier not only quarries the stone, but also processes it in-house. At our production facility, blocks are cut, machined, and finished according to the intended application.

This combination of our own quarries and in-house production gives us maximum control over quality, scheduling, finishing, and technical execution.

A single block can be used for a wide variety of applications: sills, window sills, stairs, facade plinths, coping stones, pool coping, flooring, and custom work.
