The pavement is a heart wedge - concrete is without a chance



Strolling through the streets of cities and towns of the Netherlands, England, Germany or Denmark, we look around and admire houses, cottages and office buildings with a clinker facade. When we look a little lower, we can see the clinker also on the streets, sidewalks, squares and in the gardens. Interestingly arranged clinker pavement, often cleverly combined with granite or wood, gives the places a unique elegance and charm. It is hard to believe that in many cases it is there for decades or even hundreds of years, because it still looks like new. We dream about making our city, our street and our garden look like ...

Fortunately, not only do we dream, but more and more often we begin to use these patterns and experiences in practice. We attach more and more importance to the durability of products, their practicality and elegance. That's why we replace gray, concrete and crumbled surfaces with natural material, resistant to weather conditions and almost indestructible, as evidenced by centuries-old streets with clinker surfaces. Clinker pavement works well on pavements, parking lots, streets, as well as in home gardens. Paths, terraces or driveways to the garage made from it blend in perfectly with the surrounding greenery. When we add the highest class of clinker's abrasiveness and perpetual guarantee of expressive and warm color, the choice of material for the surface seems to be sealed ...

We are all not entirely determined to get acquainted with the objective (created on the basis of Polish Construction Standard and technical manufacturers' cards) by comparison of clinker and concrete pavement. We leave your applications.

Prepared on the basis of PN-EN 1338: 2005 "Concrete paving blocks, Requirements and test methods"; PN-EN 1344: 2004 "Ceramic road brick, Requirements and test methods" and technical sheets of pavement producers.

Lack of resistance of concrete pavement even to weak acids (lemon slice) causes on its surface permanent discoloration, and with long enough effect also pitting. The photo shows irremovable stains on the concrete pavement after a 12-hour test with lemon. Clinker pavement is resistant to this type of factors, because as a result of thermal treatment it takes on a non-reactive form.

Concrete pavement due to the leaky structure of the material is not resistant to oils and other fatty substances. They sink into its surface within a few minutes, causing permanent dirt. Clinker pavement after firing gains a compact, tight structure that guarantees very low absorbability (0.8 - 3.0%), thanks to which oil does not penetrate into it.

Concrete pavement undergoes 40 times more abrasion than clinker, because its structure is made of stone aggregate surrounded by easily abrasive, hardened cement paste (cement + sand + water). Clinker pavement is a "sintered" ceramic, in which it is difficult to separate and detach individual grains, so its abrasiveness is minimal.
