These castings were produced by Hanson Precast in Houston, Texas. They are called chain walls and support buildings that are being constructed in flood areas, swampy areas or areas that have bad soil conditions. The ability to cast these structures at Hanson's facility rather than on site has saved time and allowed them to create a superior product.
Precise Forms offers a full line of one piece round or elliptical Hole Formers that are simple to install and remove. Very few hammer strikes will be required to remove the Hole Former from the casting. This is a tremendous advantage leading to extended life and service.
