Manuals and Literature

Mary Bartelme Park, ChicagoUNI-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 and products geared towards  home owners and do-it-yourself projects, please contact the local UNI® Manufacturer in your area.

Some of our most popular design manuals and brochures are included below. Some Quick Links are included at the bottom of the page for other items that may be of interest for 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.


For your convenience, you can go to our Download page where most of the items available for download on our site are all in one place.
