We are committed to developing creative solutions for all of your paving needs. Hydra-pressed / Architectural Slabs Hydra-pressed Slabs from a variety of manufacturers are used both on grade and on roof decks to protect roofing membranes against harsh weather and to create a level walking surface for patios and terraces when placed on a pedestal to allow drainage. The slabs are hydraulically pressed giving a dense, durable, non-slip surface. The mix is subjected to 400 tons of hydraulic pressure giving strength, density and durability comparable to natural stone. Using concrete pavers on roofs, plaza decks, and terraces has created new opportunities for otherwise lost space. Both amenity & non-amenity areas can now be functional, as well as attractive (including when viewed from higher elevations). The popularity of energy-efficient roofs, or "green" roofs, is increasing as its value is appreciated. Pedestal set paver installations allow easy access to the roof and waterproofing system for making repairs or standard maintenance.
