Our “Plas-Crete” precast blocks are also fully nestable, lending constructed walls additional lateral strength.

You provide the concrete pad, we provide the design and construction crew. In most cases, you’ll have a completed project in under a week!

Dimensions: 24" x 24" x 48"

Our “Plas-Crete” blocks are made from plastic enhanced concrete. We’ve replaced the stone aggregate with recycled mixed plastic aggregate, so our blocks are half the weight.
