ICRI Concrete Surface Profile Chips (Set of 10)

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]).

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.

The ICRI CSP Chips are approximately 16 square inches (3.5” x 4.5”) and are designed to replicate 10 surface profiles shown below.

Available with or without Technical Guideline (no. 310.2R-2013) Selecting and Specifying Concrete Surface Preparation for Sealers, Coatings, Polymer Overlays, and Concrete Repairs prepared by ICRI.
