A paver retainer system for use with a pedestal (10) for forming a raised floor includes a support plate (20) locatable on the pedestal, the support plate having a centre and defining locking elements, each locking element defining a radially extending upstanding fin (44), projecting through the support plate, with the fins of the locking elements being arranged at 90o to one another. The locking elements are moveable relative to the support plate. A plurality of paver supports (12), typically four, are supported on the support plate; and define depending legs which extend into the support plate, the legs defining apertures (90). The locking elements define one or more projections which are engageable in the slots (90). In a first (locked) position, the projections of the locking elements engage in the slots in the legs of the paver supports preventing disengagement of the paver supports from the support plate. In a second position, the projections are disengaged from the legs of the paver supports, allowing the paver supports to be detached from the support plate.
A tray (10) for use in a green roof system has a floor (12) and four sides (14) and is moulded from a plastics material. At the centre of, and towards the base of each side wall, there is a circular hole/orifice (20) for use in connecting the interior of one tray with an adjacent tray. The trays may be connected together using male (24) and female (30) connectors and used particularly on roofs for temporary (or more permanent water storage and as a planting box for a green roof. The trays (10) may be linked together by fluid flow connectors (50) which include a short length of piping/tubing linking the holes of adjacent trays for fluid flow between trays. Connectors which block passage of fluid between two adjacent trays are also provided. A further connector which has a partial passage including a dam wall is also provided. The trays (10) can be connected to form a reservoir on the roof of a building with the connectors being used to control the flow of water e.g blocking the passage of water on downhill slopes.
A support structure (10) for supporting a surface area or for forming a tank comprises a deck (12) and an array of tubular studs (14, 16) extending from one side of the deck. The deck (12) defines an array of apertures (18, 20) for the transmission of fluids through the deck. The studs define male (52) and female connectors at their ends distal from the deck and the lengths of the studs (14, 16) including the male and female connectors are substantially the same as each other. The structure (10) is moulded from a plastics material. The structure may be used in multiple different arrangements for different applications. In a first arrangement the structure can be used as support for a surface area with the studs (14, 16) resting on a sub- surface or floor and the deck (12) supporting the surface area. In a second arrangement two identical support structures (10) may be connected stud end to stud end to form a tank or box like structure with the male studs connected to female studs and the decks defining the top and bottom of the tank. In a third arrangement, the modules (10) may be connected to form a tank like structure with the studs of one module engaged in the apertures of the deck of another module. Multiple modules (10) may stacked together in that arrangement. In a further arrangement two modules may be nested for transport at a reduced height compared to the tanks, with the ends of the studs of one deck adjacent the other deck.
A fastener (30) for attaching surface tiles (12) or the like to a support pedestal (10), wherein the pedestal includes a base and a head member for directly or indirectly supporting a tile. Each tile corner comprises a triangular slot (24) for receiving the fastener (30), which is generally rhomboidal in shape, with a central slot (32) extending between two opposed corners of the fastener. A tab (34) projects from the corner of the fastener adjacent each slot (32) end. An anchoring means such as a screw, in use, is located in the slot, and screws into the head of the pedestal ( 10). Tn use, the fastener can be located in or moved out of the slots in the sides of the surface tiles and the sliding movement can be used to secure the tiles to the pedestal or to disengage a tile when removal of a tile is required.

A vertically-adjustable support structure (10) for supporting paving slabs or the like includes a base plate (20) on which four wedge-like support blocks (30) are provided. Each support block (30) has an inclined surface defining a series of teeth/steps, and a horizontal top surface. A chock (40) is placed on top of each support block (30) to support a corner of a paving slab. Each chock includes an upper support surface (70) for supporting the paving slab, and a sloped underside (280) which defines teeth (290) which engage the teeth of the support block and secures each chock against displacement towards the base plate. Moving the chock up or down the inclined surface adjusts the height of the support structure. Additional height adjustment is provided by adjusting the height of the chocks themselves. In particular, each chock includes wings (320) which are hinged to the sides of the chock. In one orientation with the side elements disposed on opposed sides of the chock the chock has a first height. In a second orientation, the side elements (320) are rotated about hinges (330) through 180° so that the surface which was uppermost in the first orientation is located on top of the upper surface of the chock, with the height of the chock increased by the depth of the side elements. The side elements preferably include means (340, 350; 360, 370, 380, 390) to lock them together and/or to the upper surface of the chock in the second orientation.
A tray (10) for attachment to a wall for providing a green wall is disclosed. The rear of the tray provides a series of hooks (30, 32, 34) defining apertures for attachment to a support (100, 300) in the form of a mesh, rods, bars or the like. At least two vertically spaced rows of hooks are provided for hanging the trays from the support. The lowermost row of hooks (34) is defined at the bottom of tray and directly supports the weight of the tray. Typically lowermost hooks define a leg or rib (35) at the end of which is a foot (34) on which the tray is supported when the tray stands on ground. The upper part of the apertures of the hooks which receives and rests on the support are aligned in a plane (A). The plane (A) is oriented at an angle to the axis (B) of the leg or rib of the lowermost hooks.
A vertically-adjustable support structure for supporting paving slabs or the like including a base plate on which four wedge-like support blocks are provided. Each support block has an inclined surface defining a series of teeth/steps, and a horizontal top surface. A chock is placed on top of each support block to support a corner of a paving slab. Each chock includes an upper support surface for supporting the paving slab and a sloped underside which defines teeth which engage the teeth of the support block and secures each chock against displacement towards the base plate. Moving the chock up or down the inclined surface adjusts the height of the support structure. In particular, each chock includes wings which are hinged to the sides of the chock.

A module (10) for use in a green wall system is in the form of a box (10) with a base (12), rear wall (14) sides (16; 18) a front (20), and a top (22), made from six panels which slot together. Corner brackets (60) are provided for securing the panels together and attaching the module to rails. The front (20) defines a grid of perpendicular members (30, 32) having a first thickness, creating an array of large apertures, typically up to 16 apertures each having an area of from 50cm2 to 150cm2 Two, relatively thinner bars (38), which are typically less than one fifth to one tenth the thickness/cross sectional area of the perpendicular members, extend across each of the large apertures, spaced from 4 to 6cm apart. This spacing allows most plant root balls to fit through the gap between the thinner members. In use, when the module is filled with a geo-textile bag and growing medium the bars (38) help prevent bulging of the front of the module as well as the planting bag, but are thin enough to be relatively easily removed/cut out when plants with large root ball need to be inserted in the module.
