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