WHY DO EUROPEAN ROADS & PLAZAS LAST? This question in 2010 led our founder, Robyn, on a journey where she collaborated with the president of the European Landscape Contractor’s Association to develop a system and procedure for creating enduring hardscapes with uncompromising durability.
More than 2,000 years ago, the Romans created structures that have endured centuries—roads, aqueducts, and harbors that remain intact. Their advantage? A volcanic mineral mixed into their concrete called pozzolana. This material made their concrete durable, water-resistant, and self-healing. That's why Roman concrete is known to become stronger over time. HPO’s Trass System, using our favorite Trass Mix, brings this ancient science to modern outdoor living. This European-style permeable bedding mortar combines volcanic trass with advanced polymers to create a strong, drainable foundation for pavers. It resists frost damage, controls moisture, and delivers unmatched longevity—ideal for Kansas City’s challenging climate. DISCOVER TRASS BEDDING- THE MOST DURABLE PAVER FOUNDATION IN THE WORLD
