A stormwater management apparatus and method including a water storage component, and a drainage component. The water storage component, and protective component form a composite that allows for stormwater to be retained to an appropriate extent, and for excess stormwater to be adequately controlled. The water storage component and drainage component are provided in a single unit.

The present application relates to a roof-greening grass carpet, a cultivation method thereof, and a method for one-step establishment of a turf using the same. Wherein the roof-greening grass carpet comprises a first filtering cotton layer, a moisturizing cotton layer, a second filtering cotton layer and a planting layer; the first filtering cotton layer, the moisturizing cotton layer, the second filtering cotton layer and the planting layer are arranged one after the other from the bottom up; a thickness of the first filtering cotton layer ranges from 0.8 mm to 5 mm; a thickness of the moisturizing cotton layer ranges from 3 mm to 10 mm; and a thickness of the second filtering cotton layer ranges from 0.8 mm to 5 mm; roots in the planting layer run through the second filtering cotton layer, and further root into the moisturizing cotton layer.

A waterproof connecting structure is used in coordination with a solar panel array in order to construct a vertical wall or a rooftop panel of a building. The waterproof connecting structure comprises two half components and a connecting component. The two half components are disposed between the two solar panels. The connecting component covers a joint between the two half components so that rainwater flowed into a conduit passage formed by each of the half components is guided out. Thereby, the rainwater is prevented from infiltrating into a building.

A bond adhesive composition comprising a polymer having a silicon-containing hydrolyzable terminal group and a hydrocarbon resin, where the composition is substantially devoid of phenolic resin.

Environmentally responsible insulating construction blocks and structures constructed primarily of recycled materials are disclosed. The environmentally friendly construction blocks and structures comprise shredded rubber tire pieces coated with silica fume, slag cement and cement, which are then mixed with water and formed in a mold. A layer of grout or a fireproof material may be disposed on one side of the environmentally responsible insulating construction block. The environmentally responsible insulating construction blocks can be used in place of wood blocking for roof assembly applications such as installation of a drip edge or wall coping; or in expansion joints. The environmentally responsible insulating construction blocks provide high insulation as well as strength for applications such as green roofing, wall construction and green roofing decks. Environmentally friendly structures can be built by pouring the coated shredded rubber tire pieces into molds to form walls, and then to pour a layer of the coated shredded rubber tire pieces as a roof deck, thereby creating a self-supporting structure in a monolithic pour.

A protected membrane roof system for installation on a roof decking comprising an upper insulation board having an upwardly-facing upper board top surface and an opposite downwardly-facing upper board bottom surface, a ballast material positioned over the upper insulation board, and at least one fastener assembly having a base seated beneath the upper board, a rod extending substantially vertically from the base of sufficient size so as to extend beyond the upper insulation board and the ballast material, and a cap engaged with the rod above the ballast material, whereby the wind uplift resistance of the protected membrane roof system is improved and scour of the ballast material is reduced by effectively anchoring the ballast material to the upper insulation board beneath the ballast material.

In an embodiment, a method includes applying a liquid plural component polymer to a sloped roof to form a protective surface that inhibits moisture seepage to the roof sheathing. In some embodiments, the plural component polymer may be a polyurea compound having a hardening time that is less than approximately 10 minutes. In some embodiments, one or more of the components may be aerated prior to application to the roof substrate. In some embodiments, one or more polystyrene panels may be affixed to the sloped roof prior to application of the liquid plural component polymer. Other embodiments are described and claimed.

A ballast block is provided with a body and a plurality of fluid receiving channels. The body includes a top surface, a bottom surface positioned opposite the top surface, and a first side extending between the top surface and the bottom surface. The plurality of fluid receiving channels are disposed along the first side in a plurality of units and extending from the top surface to the bottom surface to form a zigzag pattern. Each unit of the plurality of units having an adjacent pair of fluid receiving channels extending at opposing angles toward each other from the top surface to the bottom surface in an approximate V-shape.
