Grout Prism Liner

The grout prism liner meets the specific requirements of ASTM C1019. The liner utilizes a thin corrugated paper that allows moisture to pass through to the block. The grout prism spacer is durable, reusable and easy to clean. It keeps the grout prism liner square and properly aligned while assembling the block mold. Its thickness allows the specimen to maintain the correct height.
