Cost of Interlocking Bricks

Planning for a landscaping project starts with a trusted cost analysis that will help the homeowner create and maintain a budget that they can stick to. Interlocking brick is a type of material that is often used for walkways, walls, patios and driveways in many commercial properties and residential homes. The difference between regular brick shapes and slabs and interlocking brick is that the pieces must adjoin at some point. Some specialty pieces may even have holes on either end in which rods can be inserted for a secure finish. As long as the ends and pieces are flush with one another, the project can be completed successfully. Examining the overall cost of interlocking brick and learning about the different types and advantages can help take the guesswork out of the planning process.

The Costs

  • Minimum: $5 per square foot
  • Maximum: $25 per square foot


Interlocking brick involves using brick made from clay and shale that is cut to a specified shape or design that adjoins with similar pieces. Similar to a jigsaw puzzle, this type of brick design allows the installer to easily create walkways or stellar patterns in a driveway or garden patio area. Interlocking brick is almost always used to create retaining walls because of the variety of colors and versatile design. While this project can be done by any experienced do-it-yourselfer, it is recommended that a landscape designer or patio designer with a proven portfolio tackle complex projects. It is important to consider the cost of interlocking brick, specifically what type of bricks are being used. More expensive pieces of custom-cut brick can boost a project into the $1,700 range based on a 144-square-foot patio space. Bricks that require a specific design or need to be incorporated into another patio or walkway can cause the overall project cost to go up significantly.

Material Sub-types

Standard brick is the main material for most interlocking brick projects. It offers a sturdy and easily-moldable base that is long-lasting and easy to work with. In some cases, interlocking brick is also referred to as paver bricks. Paver bricks are almost always interlocking and are sought after when intricate designs are needed within the landscape. Pavers can typically run between $10 to $25 per square foot, depending on design type and availability. Many pavers need to be custom-ordered, based on how large-scale the project is. Other materials that may be used alongside of interlocking brick include flagstone and concrete. Concrete bricks can also be custom-designed and often times lend the look of expensive brick. These may be used as an intertwining material for large-scale projects to keep costs down.

There are four main types of cuts with interlocking brick:

  • Length-wise
  • Herringbone
  • Parquet
  • Irregular cut

Length-wise brick is the most commonly used type because it is easily stackable and offers a straightforward design. It is also the most inexpensive cut and is used for projects that need to keep costs within a tight budget. Recommended project uses include straight path or walkways and straight driveways. Specialty-designed, length-wise brick can also be used for retaining walls or steps.

Herringbone designs are slightly smaller than lengthwise cuts. They vary slightly in color to give a true herringbone effect to the walkway or patio. They are often used in conjunction with other interlocking brick types. Herringbone paver walkways are great accent pieces for driveways and patio areas around a pool or backyard.

Parquet cuts are used when a specific design is requested by the homeowner. Careful design and measurement is required in order to prepare for this type of project. Because of the labor and expense of the brick, professional installation is recommended. For intricate design projects within gardens or yards, parquet cuts are often accent pieces within larger-scale interlocking brick projects.

Irregular cuts of brick material are almost always needed with any project. They allow the installer to fill in gaps that occur naturally within most projects. Irregular cuts can be custom-cut to fit the needs of a specific project. In some cases, if a homeowner is looking to create a project on a budget, many wholesalers and distributors offer irregular pieces at a drastic savings. This is a great way to obtain brick at a good price and start a new project.


The biggest advantages to interlocking brick is the ability to get a custom design that highlights a backyard or front yard area. Brick is a wonderful alternative to regular concrete, giving a home more curb appeal and increasing the overall property value. Brick is long-lasting and when installed correctly resists cracking and buckling. Brick, if well maintained, can withstand heavy traffic and outlast concrete surfaces, saving time and money in the long run.


Having to custom order interlocking brick can be a huge disadvantage when it comes to price. Rush deliveries that need to be completed within 14 days can drive prices to almost double because of delivery and shipping costs. Homeowners should visit local wholesalers or distributors whenever possible in order to keep costs at minimal and to see what is in stock. There are several things to consider such as color, shape and type of brick. If the wholesaler is located out of state or across the country, costs can also skyrocket. At this point, wholesalers may offer contractors a good deal on bulk pricing or a later delivery date.

There is a lot that goes into the overall cost of interlocking brick. Other things to consider are the preparation of the subgrade or the supporting ground and the degree of complexity within the design that the homeowner wants. Permits and licenses are also something to consider when dealing with a large-scale project. Hiring professional contractors who have a proven track record of quality installation is essential in obtaining the best results.
