HydraPressed paving slabs are made from a concrete mix, using a 700 ton hydraulic press at intense pressures exceeding 2250 PSI. This process creates a product of high density and durability together with a surface comparable to that of natural stone. The compressive strength of the slabs if 8000 PSI. As the HydraPressed slab is made in a steel mold under exacting factory conditions, the product is true, square, and has clean chamfered edges to give a neat appearance, and to facilitate installation.
HydraPressed paving slabs are used for pedestrian traffic and are installed on sand, mortar, or pedestals, for patios, plaza decks, roof tops, or any other type of pedestrian walking surface.
Pedestal systems are designed for use over pitched surfaces. These systems ensure precise HydraPressed slab alignment and even spacing to allow for drainage and air circulation which are critical to the health of any deck installed over a waterproof membrane. This type of segmental system allows for ease of access for repairs or annual maintenance to the subsurface without damage to the HydraPressed slabs.
For Plaza or roof top applications caution should be exercised with respect to the weight of the product as well as the wind velocities in the areas of use.
