Mechanically restrained pedestal pavers are pavers that are physically locked to their pedestals to prevent uplift and movement caused by wind forces.

Rooftop pavers are exposed to wind uplift forces that can exceed their weight, especially under ASCE 7-16. Without restraint, pavers can lift and cause roof damage.

Yes. Urbanstrong’s concealed wind uplift restraint systems has been engineered to work in narrow conditions such as single rows of pavers, perimeter bands, and non-vegetated zones around green roofs. These edge conditions are often where wind uplift pressures are highest, so restraint is especially important even when the paved area is limited to a single 24-inch course or similar layout.

Our concealed system addresses this by modifying how the restraint engages the paver, using reduced tab counts or alternate engagement points to accommodate linear runs, herringbone patterns, or edge detailing. Urbanstrong’s concealed wind uplift solution is now available in configurations specifically designed for these conditions, including two-tab and three-tab units that allow secure restraint for single-row installations and perimeter zones. In these applications, kerf locations are adjusted to align with the restraint geometry while preserving a clean, concealed appearance.

Cap-based systems rely on visible surface hardware. A concealed system restrains the paver at the pedestal connection point, preserving clean design while improving performa

Hanover’s Guardian Paver System resists wind uplift using surface-visible restraint elements installed at the corners or intersections of each paver. These components mechanically tie adjacent pavers together to increase collective resistance to uplift forces.

Because the restraints remain visible in the finished deck surface, they can interrupt the clean appearance many designers prefer.
Urbanstrong offers a concealed wind uplift solution that restrains pavers at the pedestal connection point rather than on the surface, allowing teams to meet wind uplift requirements without visible hardware.

The Hidden LokDown System uses a concealed kerf-cut connection to restrain its dry cast pavers against wind uplift. Kerf durability depends on the manufacturing method of the paver, particularly flexural strength at the corner.

Dry cast pavers generally have lower flexural strength than wet cast pavers, which can increase susceptibility to corner chipping or breakage at the kerf during handling or installation. Urbanstrong pairs its concealed wind uplift system with wet cast pavers, which typically offer higher density, improved freeze-thaw durability, and greater resistance to kerf-related chipping in rooftop environments.

Traditional wind uplift systems for rooftop pavers often rely on surface-mounted clips, caps, plates, or bolt-down assemblies. While effective structurally, these systems can increase total project cost due to additional labor, alignment time, and coordination required during installation. In some cases, aesthetics-driven redesigns or late substitutions can further increase costs.

Concealed wind uplift systems are typically evaluated not just on material cost, but on overall installed cost. Urbanstrong’s concealed wind uplift system is designed to be competitively priced for rooftop paver projects while supporting faster installation. Urbanstrong’s system installs quickly, without adhesives or surface fasteners, thereby reducing labor time.

IteLead times for wind uplift–rated pedestal paver systems vary widely depending on manufacturing location, testing requirements, and regional distribution. Some systems are produced far from the project site or require longer fabrication cycles, which can introduce scheduling risk, especially on fast-track or phased rooftop projects.

Concealed systems that are regionally stocked or distributed can significantly reduce delivery timelines and help teams respond quickly to permitting or engineering changes. Urbanstrong, for example, ships concealed wind uplift components from New Jersey distribution point, which supports shorter lead times for projects in the Northeast compared to systems sourced farther away.

Yes. The system has been tested in Florida to extreme wind speeds exceeding 160 mph to verify high-wind performance.

 Yes. Preventing paver movement reduces membrane damage, displaced materials, and ongoing roof maintenance needs.

Insurance claims related to wind damage to roof systems may be challenged if pedestal pavers are not properly restrained. Mechanically restraining pavers helps reduce both physical risk and coverage disputes.
