There are lots of concrete pavers on the market, but Olde World Stone and Tile Molds suggests you can make them yourself for less. Raw materials for a square foot of paver cost between 28 and 65 cents, depending on thickness, according to Olde World. The rubberized ABS plastic molds should last for hundreds of pours. The company has more than 200 styles and sizes on hand and also will make custom molds. Buyers can buy just the mold or a complete kit. Prices vary by mold and kit contents: A mold to make roughly 3 square feet of “Olde Drystack Ledgestone” is about $90; a kit containing mold, release agent, sealer, concrete colorant, and concrete additive is $200.
