Many architects, homeowners, builders, designers and city planners prefer clay brick pavers over other surfaces because of their superior color retention, durability, strength, unlimited design options and low maintenance.
Clay brick pavers can be used for both interior and exterior walkways, driveways, floors, patios, and sidewalks. They are timeless and will bring a long lasting classic appeal to a residential or commerial. Clay paving brick differs from the brick used on house walls in that paving brick are solid, without holes. In addition,paving brick are fired to a different standard than face brick to insure long-term durability: ASTM C902 (pedestrian & light traffic) or ASTM C1272 (heavy vehicular).

Shale or clay is mixed with water and forced into a vacuum under high pressure. Then a column of “green” shale extrudes out the head of a brick machine. The column is cut by wires to make individual pavers. The pavers are dried and fired to temperatures in excess of 2000 degrees. 90% of clay pavers are made from this method.
Clay is mixed with water and forced into a mould made of wood. Sand is typically used to line the mould so that the green paver can be extracted. Different colored sands provide for different colors. The pavers are dried and fired as with extruded pavers. Moulded pavers are popular because they look antique.
Nearly dry clay is pressed into a steel mould under high pressure. Vacuums may be used to extract air making the paver more dense. With less moisture, dry pressed pavers will shrink less thus giving these products good dimensional stability. The firing process is similar to that of extruded and moulded pavers. The mixing process is generally done in batches that allows for easier mixing of different clays to produce color varieties.
BEVELED PAVER WITH SPACER NIBS
Beveled edge pavers in conjunction with spacer nibs offer more consistent joints and very little edge chippage. The beveled edges serve to highlight the chosen pattern offering a clean, crisp appearance. This product is intended for sand joint applications.
These pavers achieve an "old world" look through the edge rounding and chips that occur when fired pavers are rolled together in a drum. The process leaves a weathered finish like a paver that was decades old. Although this type of paver is premium priced due to the costs of processing, the authentic look is remarkable and the price is typically less than actual reclaimed clay pavers.
SIMULATED ANTIQUE PAVER
Through texturing and color applications these pavers provide an aged appearance but offer the strength of an extruded paver. The antiquing process can be applied either before or after firing. These pavers offer low edge chippage as the edges are often relieved in the texturing process. This product is intended for sand joint applications although can be placed with mortar joints.
SQUARE EDGE PAVER
The most common clay paver and generally, the most economic. As the name implies, the edges are square and slightly patina over time. This paver is the workhorse of the industry, very durable and gets used in both sand and mortar joint applications. Installers need to employ the click and drop method in order to produce proper spacing (1/8”) in sand joint applications
