Cement Gravel (Navvy Jack Blend)
C$30.00
Cement gravel also commonly known as Navvy Jack—is a sand and gravel blend used for mixing your own concrete. This material combines washed sand with ¾–1 inch round river rock, creating a clean, consistent aggregate that’s ideal for small construction projects, pathways, curbs, and DIY concrete work. Kel-Mor mixes this blend onsite using locally sourced river rock and washed sand, providing a cost-effective alternative to store-bought bagged concrete mixes.
