Hanover's Architectural Prest® Pavers are the perfect alternative to natural stone. High compressive strength and density give the product durability and low water absorption comparable to stone. Hanover® Prest® Pavers are manufactured by unique methods which duplicate the qualities of natural stone. Hanover® applies over a million pounds of pressure to each unit, fusing the aggregates and stones together. This unique process ensures a paver which is stronger and more durable than a cast or lightweight product. Hanover's test results show density, high compressive strength, and low water absorption qualities comparable to natural stone.
