UNI® Interlocking Concrete Pavers are available in several shapes that are ideal for a wide range of residential, commercial, municipal, and industrial pavement applications. UNI® Pavers are produced nationwide by a network of licensed manufacturers. They are available in an array of solid colors and blends of two or more colors. Custom colors and finishes may be produced by individual UNI® manufacturers at their discretion. Due to regional color preferences, all colors, blends and finishes may not be available nationwide. Cost varies depending on geographical area, shipping distance, shape, and color. Consult your local UNI® Manufacturer for more information.

UNI® Pavers are manufactured to meet or exceed ASTM C936 Standard Specification for Solid Concrete Interlocking Paving units, requiring minimum compressive strength of 8000 psi, maximum absorption of 5%, and freeze-thaw testing per section 8 of ASTM C67.

Segmental concrete unit pavers have been a proven paving material for over 45 years. They offer many advantages over other traditional types of concrete and asphalt pavements such as ability to withstand heavy loads, low maintenance, exceptional durability, and high quality. UNI® pavers allow access to underground utilities for repairs without leaving a patch that other paving materials leave behind.

UNI-Anchorlock's® patented anchor-interlocking shape was designed for high-load pavements and fast mechanical installation of large-scale projects.  It is especially well suited to projects such as streets, loading docks and ports. UNI-Anchorlock can be used in conjunction with permeable Ecoloc® pavers.

UNI-Decor® is a world-wide favorite that combines two shapes in one unit for a classic, elegant appearance. The dentated shape provides good structural stability as well as aesthetics. It is equally suited to residential, commercial or municipal applications.


UNI-Stone® was the original interlocking concrete paver shape designed by Fritz von Langsdorff, a pioneer in the development of the industry in Germany and North America. This shape provides superior interlocking capabilities with it's angled, dentated sides. It has been used throughout the years for heavy-duty installations, however, it is also an attractive design for other types of applications.

UNI Optiloc® is one of the newest additions to the UNI® line of interlocking pavers. This L-shaped unit combines three geometric shapes in a single design for a cobblestone appearance with superior interlocking capability. This paver is ideal for applications such as streets and plazas that experience heavier loads such as frequent bus traffic. 

Priora® is another new addition to the UNI® line of interlocking pavers. Priora can be made in a number of square and rectangular sizes and may also be used in conjunction with our permeable Eco-Priora paver. Both styles feature patented interlocking spacers that provide superior structural stability under loading. The flat surface also makes it an ideal choice for pedestrian and handicap-accessible pavements.
