This BBQ surround is cast out of GFRC high performance concrete suitable for indoor or outdoor use. This job consists of two 10 foot loong pieces with no seams and a 4" drop edge giving it a massive and heavy look. This counter is ultra high quality made from a custom blended proprietary mix. Our mixes achieve close to 6,000 psi in 24 hours and 14-18,000 psi strength in 28 days. The industry norm is 6,000 to 10,000 psi strength in 28 days as a comparison. Can be cast in virtually any size, shape and color. Price is based on per sq ft and location along with other factors. Contact me for more details and thanks for looking.
