Although concrete barriers, plastic barriers, and bin blocks are feasible for creating storage bins (mulch, sand, salt, gravel, dirt, etc.), they are not designed to hold water.
However, one model, the Water Filled Containment Barrier is designed to create a square or rectangular shape for containing water. This is the exception for a product ready to go.
If you are into modifying your barriers or concrete blocks, some folks use a sealant as they set and connect each block. This will be up to you and cannot guarantee water blockage, but is our most common solution.
