Casting your own concrete pavers for walks, patios and driveways allows you a wide range of paver styles and colours. It's not the fastest way to complete a paving project, as the concrete must be allowed to cure for several days before being removed from the mould. However, casting your own pavers can save you money and give you greater control over the finished project.
One of the most familiar shapes for pavers is the paving brick, or rectangular paver. These bricks are usually around 9 inches in length and 5 inches in width. Pavers for walks and patios are usually cast about 1 1/2 inch thick, but pavers for driveways and other areas exposed to vehicle traffic should be 2 1/2 inches thick.
Keystone pavers are shaped like keystones, or truncated triangles, and are usually about 6 inches wide at the base and 4 inches wide at the top. These pavers may be oriented side by side in opposite directions to create straight courses of pavers or arranged with their wide sides facing outward to form circular patterns. Alternating keystones can also be made in contrasting colours to create a vivid pattern effect.
Keyhole pavers are shaped like octagons with short square tabs projecting from one side. They are arranged in interlocking patterns that provide a great deal of visual complexity. They also distribute weight more irregularly than rectangular or square pavers, and are less likely to separate from each other under load.
One of the most eye-catching styles of paver moulds are tessellated pavers, complex, nonsymetrical shapes that lock together in several orientations. Available shapes include pavers that look like puzzle pieces and others that look like frogs or geckos. While these unusual pavers are no more difficult to cast than plain old bricks, laying them out on a walkway or patio might be a dizzying experience.
