Wood permeable pavement is a natural and sustainable building material. Architects and landscape designers turning towards permeable pavers will find that some types of highly durable hardwoods (e.g. Black Locust) are an effective permeable pavers material. Wood paver blocks made of Black Locust provide a highly permeable, durable surface that will last for decades because of the characteristics of the wood. Black Locust Lumber wood pavers exceed 10.180 PSI (pounds per square inch) and have a Janka Hardness 1,700 lbf. They are suitable for pedestrian and vehicular traffic in the form of pathways and driveways and are placed upon permeable foundations.
