The invention relates to a paver supporting apparatus. The paver supporting apparatus has a pedestal with a top plate. A modular grid is positioned on the top plate and has a ballast receiving opening and a ballast is located in the ballast receiving opening.

Systems and modular devices for roof or ground-level stormwater management are disclosed. A modular stormwater management device includes a water retention mat structured to absorb stormwater, a rigid frame structured to support the water retention mat, and a perforated surface structured to permit drainage of the stormwater from the water retention mat through the perforated surface. A modular stormwater management system includes a plurality of modular stormwater management devices, each of the modular stormwater management devices including a water retention mat structured to absorb stormwater, a rigid frame structured to support the water retention mat, and a perforated surface structured to permit drainage of the stormwater from the water retention mat through the perforated surface.

A corrugated plate assembly includes at least two corrugated plates each having a crest portion. The crest portion is asymmetric and includes first and second arcuate ends, two longitudinal lateral sides connected between the first and second arcuate ends and two indentations indented from the first and second arcuate ends. The second arcuate ends of the corrugated plates are interconnected in such a manner that the indentations of the second arcuate ends are intersected each other and that the second arcuate ends overlap with each other. Ventilation gaps are formed between overlapping parts of the second arcuate ends.

The present disclosure provides a paver lockdown system that prevents strong wind from uplifting pavers from pedestals installed on rooftops.

A water barrier system to protect a roof surface from environmental conditions is disclosed. In one embodiment, the water barrier system includes an underlayment layer and a liquid applied coating. In use, the underlayment is coupled to the roof surface. Thereafter, the liquid coating is applied to the underlayment to form a barrier layer. The underlayment may be manufactured from a porous material so that the liquid applied coating is at least partially absorbed by the porous underlayment. In this manner, direct application of the liquid coating to the roof surface is eliminated. In one embodiment, the underlayment may be provided with a load bearing component/layer and a coating absorbing component/layer. For flat roof applications, the load bearing component/layer may be provided with increased rigidity for dimensional and installation stability. Meanwhile, for roof penetration applications, the load bearing component/layer may be provided with increased elasticity to enable the underlayment to wrap about the penetration.

A corrugated plate assembly includes at least two corrugated plates each having a crest portion. The crest portion is asymmetric and includes first and second arcuate ends, two longitudinal lateral sides connected between the first and second arcuate ends and two indentations indented from the first and second arcuate ends. The second arcuate ends of the corrugated plates are interconnected in such a manner that the indentations of the second arcuate ends are intersected each other and that the second arcuate ends overlap with each other. Ventilation gaps are formed between overlapping parts of the second arcuate ends.

A ventilating and heat dissipating assembly for a roof includes hollow bricks, first corrugated plates and second corrugate plates. Each first corrugated plate spans a gap between two pairs of the hollow bricks that are spaced apart along intersecting first and second directions. Each second corrugated plate spans a gap formed between two of the hollow bricks spaced apart in the first direction and a gap between two of the first corrugated plates spaced apart in the second direction.

A hollow brick includes a bottom wall, two side walls projecting from the bottom wall, a plurality of intermediate walls projecting from the bottom wall between the side walls, and a top wall opposite to the bottom wall and connecting the side walls and the intermediate walls. A plurality of ventilation holes is bounded by the bottom wall, the side walls, the intermediate walls and the top wall. Each ventilation hole has two ventilation open ends opposite to each other along the transverse sides of the bottom wall. Two outer holding ribs projects respectively from outer surfaces of the side walls in opposite outward directions.
