Located in Sinking Spring, Pennsylvania, just 50 miles west of Philadelphia, C. Strunk, Inc. continues to provide their customers with quality and reliable service. A locally-owned business operated by the same family for five generations, C. Strunk, Inc. is ready to bring that high level of service to meet your Reading PA concrete block needs for the next millennium.

When Clarence Strunk purchased the small tract of land along the Green Valley road in Sinking Spring, he started crushing limestone and making the unique Reading PA concrete block by hand, one block at a time. Over the years, the #1 Reading PA block producer has grown from 300 blocks a day to over 6,000. Today, the business is run by Clarence's great-grandson. Stephen Strunk runs the business along with his wife and son, proving that the American dream is alive and well in the 21st Century.
