Limestone, a sedimentary rock primarily composed of calcium carbonate, presents a unique set of challenges when it comes to drilling operations. This ubiquitous rock formation, formed over millions of years through the accumulation and compression of marine organisms, is found globally and plays a significant role in various geological processes. Drilling through limestone requires a comprehensive understanding of its properties and specialized techniques to ensure efficient and safe extraction.

molded frp gratings are manufactured in a one piece construction which results in a bi-directionally strong product. This allows openings for piping or cables in the grating of up to 10” without any additional support required (may vary depending on grating depth and location of opening). During the molded manufacturing process, the continuous fiberglass rovings are completely covered in a high percentage of resin, 65% by volume. With this high resin content, molded gratings are the most chemically resistant gratings offered and are often used in caustic chemical environments without hesitation.
