Under the name TERCA, Wienerberger offers an extensive program of facing bricks from the individual regional companies.
No other manufacturer produces such a large range of colours, surface textures and shapes. Wienerberger is therefore your most competent partner for brick façades. Our advisors at the regional companies will be happy provide you information about our extensive product range.
The TERCA hand moulded bricks are produced by the oldest method for manufacturing facing bricks is the hand-moulding method. First the raw material is rolled in sand then thrown forcefully into a dry mould. The sand acts like flour in a cake mould. The excess material is stripped off with a wire or a piece of wood.
The TERCA stock bricks are manufactured according to a similar principle, with the raw material being pressed into the mould under high pressure. This results in bricks with more subdued shapes and surface structures, and like hand-moulded bricks, five sides are sand-coated.
TERCA water-struck bricks also have a rustic appearance and sharp edges. They are manufactured on water-streaking revolving presses according to a long tradition. In this process, the moistened clay is thrown into a wet wooden mould. When the mould is lifted up, the water acts as a "lubricant" and draws the typical streaked design into the surface of the brick.
TERCA extruded bricks from Wienerberger are produced through extrusion of the carefully prepared clay. This gives them clear edges and smooth surfaces to which additional texturing can be added through sanding, milling, engobing, glazing or brushing. It is also possible to give them an "antique" look through subsequent tumbling of the bricks.
Engineering bricks are produced by firing at temperatures above 1100 degrees Celsius. At these temperatures, the brick begins to melt, called "sintering". The fine pores in the raw material close. The finished engineering quality brick has an extremely high density and is very hard and frost-resistant. Water cannot penetrate, thus being impervious to moisture.
TERCA pit-fired and ring-kiln-fired bricks are manufactured by hand according to a very traditional process. The firing takes place in historic pit-firing or ring kilns. This refined brick-making art produces bricks that are all individually unique.
