Sferio Magma

Manufactured product


Sferio is a new addition to our Kellen concrete paving range and is a first in the marketplace. Using small stainless steel pellets, the top layers of the setts and slabs are lightly shot-blasted to produce a subtle polished appearance.

The top layer consists of 100% natural aggregates, made from a blend of fine grain sizes that preserves original colours and provides an extremely hardwearing surface. Less susceptible to general fading and easy to maintain, Sferio’s dense structure makes it difficult for dirt to penetrate. As a C4C compliant product, it is also an environmentally-friendly choice. More details on the C4C standard can be found on page 8 of this brochure.
