Product Information

TRAP ROCK is a combination of 100% graded trap rock and portland cement. It is a polyhedral shaped, abrasion resistant, chemically inert, non-absorbent aggregate produced from igneous rock. This dense mineral aggregate is crushed into a polyhedral shape. It is carefully graded to assist ease of placement. This results in interlocking dense mass that produces high performance floors for abrasion resistance. Properly placed, TRAP ROCK reinforces the near wear surface of high traffic floors with one of the densest, most abrasion resistant aggregates on the market today.
