A stake consists of two planar panels joined on a longitudinal axis and angularly disposed with respect to one another. Lower portions of the panels converge to a tip on the axis, and an axial tang is formed at the top of the stake. An inwardly directed flange is formed near the top of each panel, the flanges being disposed substantially in a common plane, generally perpendicular to the panels. The flanges and the tang facilitate driving of the stake into a substrate by use of a power hammer, and the driven stake resists both upward and lateral displacement. It is especially adapted for the securement of edging for restraining paving and landscaping materials.

There is disclosed a foundation system made up of panels for supporting a load bearing surface on underlying ground in use. Each foundation panel has a panel body having a peripheral edge, first and second opposing major surfaces spaced by a depth dimension of the panel body, and a plurality of internal walls upstanding in the depth dimension so as to define a plurality of cells within the panel. Each cell of the panel is open at one of the first and second major surface and closed at the other of the first and second major surfaces. Connection formations are provided at the peripheral edge of the panel body, where the connection formations comprise a neck portion and a head portion. The head portion is configured to engage with a corresponding connection formation of one or more adjacent panel in use to resist separation of the foundation panel from an adjacent panel in a direction within a plane of the first or second major surface. A support surface may be assembled using multiple foundation panels, each connected to an adjacent panel.

A tile, which may be a component of a modular flooring system, includes a plurality of cells on its underside, adjacent cells being interconnected to form two sets of channels parallel to the upper surface and open to the underside of the tile. The tile may have recesses in its upper surface, into which inserts can be pressed to form a decorative pattern. The channels may be used as ducting for cables under the floor surface. The cables can be held in place by clips that bridge between a pair of the cells. The cables may include a lighting cable, which can be arranged to transmit light to the upper surface of the tile through inserts that are translucent.

A joint edge protection apparatus for protecting an edge of a first component formed of settable material and an edge of a second component formed of settable material at a joint, wherein the apparatus includes a first anchorage part for anchoring within the first component and a second anchorage part for anchoring within the second component, a first plate coupled to the first anchorage part, a second plate coupled to the second anchorage part, the first plate defining a first abutment surface, the second plate defining a second abutment surface, wherein the first abutment surface and the second abutment surface are shaped to facilitate abutment of at least a portion of the second abutment surface against the first abutment surface, and wherein the second anchorage part is adapted to be movable relative to the first anchorage part from an abutting configuration in which at least a portion of the second abutment surface is in abutment with the first abutment surface to a spaced configuration in which the second abutment surface is spaced relative to the first abutment surface, wherein the first anchorage part defines a support surface to support the second plate as the second anchorage part is moved between the abutting configuration and the spaced configuration, and wherein, in the abutting configuration an interface between the first abutment surface and the second abutment surface is offset relative to an interface between the first anchorage part and the second anchorage part such that the interface of the first abutment surface and the second abutment surface is positioned above the support surface.

A retention system for retaining a milling drum to a driveshaft of a milling assembly. The driveshaft is powered to drive the milling drum about an axis. The retention system includes a retention member coupled to the driveshaft between a first position and a second position. In the first position, the retention member restricts a disengagement between an engagement surface of the driveshaft and a mating surface of the milling drum, inhibiting a release of the milling drum from the driveshaft along the axis. In the second position, the retention member provides clearance for the disengagement of the engagement surface and the mating surface, facilitating the release of the milling drum from the driveshaft along the axis.

An edge protection system for use with concrete flooring, including a first part for coupling to an edge portion of a first concrete flooring panel and a second part for coupling to an opposed edge portion of a second, neighbouring, concrete flooring panel, and a support foot for supporting the system relative to a ground surface, wherein the first part has a pair of vertically opposed longitudinal rails, and the support foot has an engagement formation which has an unlocked orientation for inserting the formation between the opposed rails to abut against the first part and a rotated, locked orientation wherein the formation is locked by the rails against lateral withdrawal from the first part.

Disclosed is a multifunctional synthetic resin block for roads. The synthetic resin block includes a water permeable sheet configured as a synthetic resin block having a flat sheet shape so as to be laid on a ground, a block frame configured as a synthetic resin body taking a form of a rectangular frame, which is divided into multiple rectangular areas each having open top and bottom sides, so as to be installed on the upper surface of the water permeable sheet, the rectangular areas being filled with filler stones, and multiple corrugated plates each configured as a synthetic resin having a rectangular plate shape and arranged so that corrugations thereof are oriented perpendicular to each other so as to cover the rectangular areas of the block frame. The synthetic resin block provides almost all functions, such as a rainwater retention function, water permeation function, and anti-slippage function, at low cost.
