Traditional and Heavy-Duty Pavers

Port of Mobile, ALUNI® 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 Interlocking Concrete Pavers can be used for a wide array of paving applications, including residential, commercial, municipal, and industrial projects.
