Paper Sheets for Cement Grout Flow, Package of 100

Supported Standards: ASTM C1019

Grout Paper is a reliable and cost-effective solution for creating grout test specimens in accordance with ASTM C1019. Each sheet is precision-cut to 7½″ x 12″ and scored at three points, allowing it to be easily folded into a 3″ x 3″ x 7.5″ prism mold. Once folded, the molds are placed into a cavity formed by arranging concrete masonry units (CMU) and/or bricks to the same dimensions, after which grout is placed and consolidated into the paper-lined cavity.

Why Choose Humboldt Grout Paper?

• Cost-effective: Grout Paper is a more economical alternative to corrugated cardboard boxes, even when producing up to four specimens at a time.
• ASTM C1019 compliant: The permeable material meets the ASTM C1019 guideline for a thin, permeable barrier that prevents bonding between the grout and the mold.
• Consistent results: Unlike thinner materials, our grout paper is rigid enough to maintain the correct shape during casting, reducing the risk of producing irregular specimens.
• Simplifies testing: Using Grout Paper eliminates the need to produce comparison samples when considering alternative test sample methods, as outlined in ASTM C1019.
• Easy to use: The pre-scored design makes folding quick and straightforward, saving time on the job site or in the lab.

Whether you're testing in the field or the laboratory, Grout Paper delivers consistent, reliable results while keeping costs low.
