Mechanical InstallationUNI-GROUP U.S.A. offers extensive design and installation information for both traditional and permeable interlocking concrete pavements (PICPs), including design manuals, specifications, case studies and design software. This information is geared to design professionals and contractors. For information geared towards the homeowner and do-it-yourself projects, please contact your local UNI® Manufacturer.

For your convenience we've included Quick Links below for items of interest pertaining to design and construction. Permeable interlocking concrete paver design and construction differs from that of traditional pavers, so the information is often presented in two formats for your convenience.

Proper design and installation is very important to ensure a quality interlocking concrete pavement that will perform as intended, whether the project is a heavy-duty industrial shipyard or a pedestrian pathway. Traffic loading is a critical element in the design of interlocking pavements, and UNI Pavers feature interlocking shapes that enhance structural strength and stability. Interlocking concrete pavements are exceptionally durable despite their attractive appearance.

UNI Interlocking Traditional and Permeable Concrete Pavers can be installed either manually or mechanically. In mechanized paver installation, specialized paver installation equipment speeds construction time by installing approximately one square yard (one square meter) of pavers at a time in rapid succession. For an Interlocking Concrete Pavement Institute Tech Spec on Mechanical Installation visit your local UNI Manufacturer's web site or visit our Downloads page. ICPI Tech Specs are also available on Edge Restraints, Construction, Structural Design and more.

It is recommended that installation be performed by experienced interlocking concrete paver contractors that preferably are certified by the Interlocking Concrete Pavement Institute. Pavement design and installation varies with climate, available construction materials, design methods, soil conditions, and traffic loads. A qualified engineer, architect, and/or landscape architect should be consulted in concrete paver applications.

With permeable interlocking concrete pavements, you must not only design and construct for structural loads, but also for the hydraulic/hydrology component of water entering into the pavement structure. This requires the services of a professional engineer or other design professional with experience in hydrology and hydraulics.

We offer a number of guide specifications for the construction of traditional and permeable interlocking concrete pavements. The most common guide specifications are provided below. For other specifications such as construction over a cement-treated base, an overlay over existing concrete or asphalt, or bitumen-set applications, you may download these files by visiting our Downloads page. If you require an editable Word Document version of these PDF specification documents for editing purposes, these are also available on our Downloads page..
