A flood-resistant building is equipped with a flood barrier which enables safe and long-term refuge during floods. In a site surrounding a building, a flood barrier is constructed which encloses nearly the entire periphery of the building. An opening sealing means is connected to an entrance hall and another section serving as an entrance and exit at normal times. The opening sealing means seals the openings of these sections in a watertight manner where the openings are sealed via the opening sealing means. The flood barrier is watertight and at least as tall as the inundation depth estimated to occur in a target area when flooding or storm surges arise. In order to enable long-term refuge, an emergency-use water receiving tank 4 and an emergency-use generator are installed on the roof of the building, and an emergency-use septic tank is installed underground on the site.

Modular multipurpose, rapidly deployable, barriers that couple together into barrier walls and barrier blocks. The barrier walls are watertight, self-filling, and capable of being coupled horizontally without vertically lifting the barriers. The barriers are capable of being vertically and horizontally stacked in all directions while also allowing the stacked blocks to be offset and reinforced with poles, ropes and cables that thread through the stack vertically to support fencing and other materials. Horizontally, the barriers also permit poles, ropes and cables to be thread through the barriers greatly increasing their strength. The modular barriers are also stackable to be efficiently stored within truck and shipping container. The barriers may also be bullet proof.

Disclosed is a protective barrier segment for a temporary liquid-damming protective barrier configured for separating a flooded side from a protected side by abutting against a ground surface, the protective barrier segment including a liquid-damming member having a first surface facing the flooded side and a second surface facing the protected side. The protective barrier segment is characterized in that the liquid-damming member includes an opening connecting the flooded side and the protected side and in that the protective barrier segment further includes a pump arrangement, wherein the pump arrangement is located at the opening in sealed engagement with the liquid-damming member and wherein the pump arrangement, in use, pumps liquid from the protected side to the flooded side. Also disclosed is a protective barrier including such a protective barrier segment.

A modular building block apparatus for the construction of a coastal or river bank erosion defence or protection structure includes a plurality of blocks arranged in stacked rows, the blocks in each row having cooperating formations whereby the blocks in each row are interconnected with one another. Apertures formed in each block extend perpendicular to the rows, and a plurality of connector members extend through aligned apertures in adjacent rows of the blocks to interlock the rows to one another.

A flood barrier to protect an area of land from floodwaters, the flood barrier having a waterside to be placed adjacent a body of water and a protected side opposing the waterside, the flood barrier comprising a plurality of supports spaced apart from one another; at least one intermediate barrier section supported to extend between a pair of neighbouring supports when assembled, the intermediate barrier section comprising at least a first beam arrangeable such that it is supported to extend between the corresponding pair of neighbouring supports and a water impermeable membrane sheet attachable to said first beam via a mechanical connection to form a skirt extending from said first beam, outwardly from the waterside of the flood barrier onto the ground.

Protection of upland areas adjacent to a variety of water body shorelines from flooding events by combining modified drainage culverts with and hidden by natural ecosystem flood attenuation environments.

A pile mechanism to support water barrier elements in a self-closing flood barrier is described. The pile mechanism includes a pile that is arranged substantially beneath ground level when the water level is below the ground level, and that is automatically positioned above the ground level when the water level rises above the ground level. In some embodiments, the pile mechanism has a central float that is suited to cause the pile to rise at a water level that is higher than the ground level, a cover element suited to provide a water-tight seal between the pile and at least one water barrier element of the self-closing flood barrier, and a well having at least one flotation compartment from which the pile rises by means of the central float positioned in the flotation compartment.

A retaining wall extension system for extending a retaining wall, wherein the retaining wall includes an existing wall cap having an upper surface defining an elevation of the retaining wall, with the upper surface having a length and a width. The retaining wall extension system includes an extension cap arranged to be received by the existing wall cap of the retaining wall. The extension cap includes a first portion arranged to be received by the upper surface of the existing wall cap, and a second portion integrally formed with the first portion, wherein the second portion extends vertically upward from the first portion so as to extend the elevation of the retaining wall. A method of extending a retaining wall is also provided.
