The 24-inch holes you see here
for the new sams express car wash on Providence Rd, Waxhaw, NC needed some more core drill holes in them because they did not come from the concrete fabrication plant as needed. Often we perform core drilling services for plumbers who need more holes in the concrete slug boxes or water basins than the engineer called for. These 5-inch holes were just the size needed to ensure that a 4-inch pipe would pass through for plumbing.
