Why laser engraved bricks? To avoid weather deterioration, we employ the laser-engraving process, and do so because of the precision and permanence laser-engraving produces: an intense heat is precisely focused upon the clay brick’s surface, which momentarily melts the sand (silicon) and metallic oxides within the clay, thus reconstituting them as a black, ceramic glazed depression, i.e. the lettering. The resulting lettering is thereby permanently bonded to the surrounding material and “sealed,” rendering it impervious to water penetration and permanently ensuring color contrast with the natural brick color.
Our patented laser-engraving process is very different from the traditional method of “sandblast and fill” engraving which requires the deeply cut, bare lettering cavities to be filled with lithochrome paint, grout, or epoxy so as to achieve color contrast with the surrounding material.
Regrettably, all of these “fills,” exposed to the elements and debris which collect in the lettering cavities, tend to fade and wear away…in a distressingly short time. Weather damaged “sandblast and fill” lettering is evidenced in the photos below. Such weather deterioration, unfortunately, is to be expected of “sandblast and fill” engraved pavers.
In northern climes especially, this is a critically important consideration. Exposure to the elements, particularly freeze/thaw, ice/snow, harsh de-icing chemicals, ultra-violet sunlight, abrasion by sand/dirt, and wear, simply will not deteriorate our laser engraved lettering. We, of course, warranty this assertion.
Laser-engraving renders permanence and precision…is superior…is permanent…and will not suffer such weather-induced damage.
