Review on GLEEJON Interlocking Drainage Flooring with Splicing Capabilities by Mike Bigglesworth

Easy to attach, secure enough to stand and walk on and easy to walk on. Probably not strong enough for anything other than carrying a person or a wheelbarrow. I cut out the rubber where I attach some 4x4 bars for the bottom shelves. It's firm but soft. The bottom supports are spaced 1.5 inches apart, but that's a good narrowness for, say, a kitchen.
