A structural system that includes at least two pavers partially defining a paved surface, the pavers partially defining a void between them. The system also includes a permeable joint located in the void between the pavers, where the permeable joint also partially defines the paved surface. The permeable joint includes a base layer formed of aggregate and bonded together with a non-cement binder, and a membrane layer formed of aggregate that is sized smaller than the aggregate of the base layer, where the aggregate of the membrane is also bonded together with a non-cement binder. The membrane is less permeable than the base layer and is located above the base layer.

The invention is directed to a photovoltaic multilayer laminate, to a method for preparing a photovoltaic multilayer laminate, to a method for preparing a photovoltaic roadway, and to a photovoltaic roadway.

The photovoltaic multilayer laminate of the invention comprises multiple flexible photovoltaic foil elements laminated at least to a carrier layer comprising electrical interconnections for said flexible photovoltaic foil elements, wherein said multiple flexible photovoltaic elements are arranged transversely to the longitudinal direction of the laminate, wherein a stretchable or compressible space is provided between each pair of multiple flexible photovoltaic foil elements.

Provided is a block compactor equipped with a brake mechanism capable of securely locking rollers with a simple structure and stably maintaining a locked state and an unlocked state even when exposed to vibration. A brake pad 12 is fixed to a lower end portion of a brake shaft 11 and is configured to be rotatable together with the brake shaft 11 between two rollers 5 adjacent in the front and rear. By rotating a brake lever 13, the brake pad 12 can be switched between an unlocked state in which the brake pad 12 does not contact with the outer circumferential surfaces of the rollers 5, and the rollers 5 are free to rotate, and a locked state in which the brake pad 12 contacts with the outer circumferential surfaces of the rollers 5, and the rollers 5 cannot rotate with the friction force.

A series of modules serve to provide a base for walkway members to be assembled into a walkway. Modules provide for support and orientation of walkway members and the ability to produce complex walkways with segments at varying orientations. In a preferred embodiment, a base mat is sized to engage walkway members. Using a combination of a number of base mats and walkway members, segments of walkway of any desired size can be readily assembled. Reflective and non-slip surfaces can be applied to increase safety when in use.

An apparatus for treating water in soil-less growing systems has a container having a cross-sectional area and a height, with a first access port for liquid at an upper end, and a second access port for liquid at a lower end, and a porous matrix filling the container, the matrix comprising a hydrophilic polymer mixed with rocks and natural minerals. Water drawn from a soil-less growing system, is urged into the container through one of the liquid access ports, causes the water to flow through the matrix in the container, the water in contact with the rocks and natural minerals in the matrix, leaching elements from the matrix, and causes the water to exit the container at the other of the liquid access ports, to flow back to the soil-less growing system.

A structure has a high-impact plastic polymer tile comprising interconnected individual cells, each having an outer wall of a vertical dimension forming a closed outer periphery, and a matrix filling the cells from a lowermost extremity of the walls of the cells, to level below an uppermost extremity of the internal walls of the cells, the matrix comprising material supporting plant growth. With the tile lying on a base surface, the individual cells of the tile constrain the matrix material from horizontal translation, and wherein the walls of the cells, extending above the level of the matrix in the cells, provide support for any wheeled vehicle without disturbing the matrix.
