Pavers Information

Selecting pavement pavers bricksPavers consist of pre-cast blocks or bricks utilized in exterior hardscaping to create even, unobstructed surfaces for people and vehicles. They are made from a selection of materials, including molded concrete, kiln-fired clay, rubber, grass, and natural stone.




The pre-cast blocks come in an assortment of configurations. High thicknesses are preferable for road construction and heavy-duty purposes such as freight yards and airports. Consumer usages, such as driveways, walkways, patios, and porches, do not require the same integrity. Pavers come in a wide variety of sizes; some types interlock when laid down and do not need a concrete foundation.


Blocks characterized as permeable allow fluid to drain through the structure instead of pooling water and creating run-off. These versions comprise concrete- or polymer-based substances. Concrete pavements with porosity enable the draining of fluids via base layers of stone. On the other hand, polymer pavers, such as grass, reinforce the load-bearing capacity of unpaved surfaces consisting of gravel or turf.


Concrete structures gained popularity in Europe following World War II as an affordable means of rebuilding streets. Interlocked pieces last longer than poured concrete and asphalt and are suitable for sand or gravel foundations. Pre-cast units are removable for road repairs, which reduces demolition costs when replacing a solid street surface. Pavers also are better for slightly uneven terrain. Depending on the need, pavers are either hand set or machine laid.




Pavers are produced in several variations. The most common categories are described below:


Natural stone: The durability and strength of these materials allow them to withstand harsh climates. Once extracted from quarries, the stone is cut into shapes appropriate for placement. Natural stone classes include bluestone, granite, travertine, marble, and flagstone. Their physical appearance is prized for its decorative appeal. They are found in garden steps, pathways, patios, driveways, and pool areas.


Concrete: Cement and aggregate are the two primary ingredients for constructing concrete units. Concrete surfaces withstand harsh environments caused by weather or heavy foot and road traffic. Some concrete versions are built to simulate natural stone. They are less expensive, making them appropriate for projects where cost is an issue. Such blocks feature many colors preserved with a color sealant.


Clay brick: Natural clay kiln-fired at very high temperatures serves to bond ingredients, enhancing the strength of the materials. As clay is a natural material, bricks made from clay maintain their color for an extended period. The designs exist in numerous arrangements, including rectangles, bull nose, boardwalk, and interlocking octagons.


Clay brick units support a diversity of styles, including:


  • Extruded: A mixture of clay and water is forced into a vacuum using high pressure. At this stage, a "green" shale column extends from the head of a brick machine and wires cut into the column to create individual parts. They are then dried and fired at extreme temperatures. The vast majority of clay structures are built via this method.
  • Molded: A mold built from wood is filled with a blend of clay and water. Sand serves as a liner for the mold. Sands of different colors allow for the manufacturing of bricks of many colors. As with extruded arrangements, drying and firing follow. This procedure is similar to methods engaged in prior centuries, giving the pavers an aged or antique look.
  • Dry Pressed: Clay in a dry state is pressed into a mold made of steel using high pressure. Air is extracted through vacuums to form denser units. The lack of moisture present in the dry pressing means pavers contract less, enabling these products to possess excellent stability. A firing technique similar to extruded arrangements is involved. Mixing is performed in batches of various clays to yield the multiple color shades.

Rubber: Recycled tires and other supplies make up the foundation for the rubber equivalents. They are installed in areas such as sporting arenas, stables, and gymnasiums. Installation of this selection is easy, and they feature low maintenance costs. Their non-slip nature makes them ideal for situations where safety considerations apply.


Permeable/porous: Permeable components display a solid surface with spaces in between the units to enable drainage. Porous products have surfaces with holes allowing water or other fluids to drain through to the soil and are filled with vegetation or aggregate. Both porous and permeable styles offer the additional benefit of avoiding the transmission of runoff into storm drains or other drainage structures. They comprise porous asphalt, concrete, and polymer-based structures using grass or aggregate. Other forms of permeable surface covering include plastic turf reinforcing grids (PTRG) and geocells built from polymer alloys.


Permeable products have the following benefits:


  • Decrease in demand for water via paving over grassy areas
  • Reduction in erosion rates occurring due to a lack of flora, thereby aiding landscaping
  • Removal of standing water to limit mosquito populations
  • Longer lasting than traditional paved surfaces
  • Replenishment groundwater supplies
  • Lower heat island effect through the use of light-colored, reflective pavers
  • Limiting the runoff of pollutants into drainage systems
  • Minimizing the need for storm water retention systems
  • Suitable for installation in remote areas without extensive construction infrastructure

  • Easy removal



The broad array of applications includes:


  • Decorative hardscaping
  • RV access and boat parking areas
  • Overflow parking
  • Fire lanes
  • Emergency vehicle access lanes
  • Parking lots
  • Golf cart and pedestrian paths

  • Recreational fields



When it comes to pricing, most concrete block alternatives are less expensive than fired clay bricks. Natural stone products cost more than both, given the difficulty in finding and shaping the rock. Specific applications require permeable components to deal with water runoff. This is common in communities where water is scarce or strict pollution controls are in effect. In these cases, permeable or porous pavers are desirable. Applications requiring certain load bearing attributes exist as well.
