Concrete Surface Profile Chips with Technical Guide

The International Concrete Repair Institute (ICRI) produces 10 distinct concrete profiles formed by various surface preparation methods. Each profile carries a CSP number ranging from CSP 1 (nearly flat) to CSP 10 (very rough; amplitude greater than ¼” [6 mm]).

The guide provides owners, specifiers, contractors, and manufacturers with the information required to select and specify the methods for preparing concrete surfaces prior to the application of a protective system or repair material.

These chips are designed as a visual and tactile comparator for identifying the degree of surface roughness. The user compares prepared concrete to the CSP chips and reports the chip number that most closely resembles the surface. Many jobs will specify the type of surface preparation required.
