About
Riprap consists of heavy stone used for erosion control, weighing about 100 pounds per cubic foot (1.6 grams per milliliter).
Riprap has a typical bulk density of about 100 pounds per cubic foot (1.6 grams per milliliter). Because it is made of loose, jagged chunks of rock or crushed concrete, empty spaces between the stones lower its overall bulk weight compared to a solid slab of stone. It settles at a similar weight to packed sand and sits much heavier than loose gravel or soil. A standard 5-gallon (19-liter) bucket filled with riprap weighs around 67 pounds (30 kilograms).
From Wikipedia
Riprap, also known as rip rap, rip-rap, shot rock, rock armour or rubble, is human-placed rock or other hard, heavy, unconsolidated material used to protect shoreline structures against scour and water, wave, or ice erosion. Riprap is used to armor shorelines, streambeds, bridge abutments, foundational infrastructure supports and other shoreline structures against erosion.
