Rock armour, also known as riprap, is a form of coastal defence, typically used to reduce erosion caused by water, waves, and wind. It consists of large, durable rocks placed along shorelines, riverbanks, or the foundations of structures to absorb and disperse the energy of waves and currents, thus minimising their destructive impact.

Riprap (in North American English), also known as rip rap, rip-rap, shot rock, rock armour (in British English) or rubble, is human-placed rock or other material used to protect shoreline structures against scour and water, wave, or ice erosion. [1][2][3] Riprap is used to armor shorelines, streambeds, bridge abutments, foundational ...

Rip Rap is a coarse rock available in a size range of 300-700mm to 500-700mm. It's an effective choice for the protection of shorelines, structures and rivers offering long lasting wave dissipation and scour protection.

2022年10月2日 · Riprap, also known as rip rap, rip-rap, shot rock, rock armour or rubble, is rock or other material used to armor shorelines, streambeds, bridge abutments, pilings and other shoreline structures against scour and water or ice erosion. These are the typical uses for riprap, but other uses are on a steep graded hill to prevent weather related ...

What is Rock Armour Stone? Rock Armour Stone, also known as armourstone or riprap, is large, heavy, natural stone typically used for coastal protection, erosion control, and landscaping. It is characterised by its size, and its irregular shape.

Rock armour is a barrier formed by large boulders that prevents erosion of coastal features such as beaches and cliffs. Rock armour, also known as riprap, provides protection against serious erosion by absorbing wave energy.

Also known as 'rock armour', rip rap involves placing large rocks and boulders in front of a cliff, sea wall or revetment. They are similar to gabions in their purpose, however they are not fixed in place with mesh like gabions are.

Rock armour is also known as rip-rap. It is made of hundreds of huge boulders of hard rock such as granite, and acts as a barrier between land and sea. Their downward slope arrangement …

Rock Armour works by absorbing and deflecting the impact of waves before they reach the beach or defended structure. The mass of the material absorbs the impact energy of storm waves, whilst the permeability (gaps between the rocks) slows the flow of water, reducing the erosion effect around structures or on the coastline.
