Interlocking Strength
Unlike smooth, rounded stones that slide past one another under pressure, the angular shape of this material facilitates a mechanical bond. Each shard interlocks with its neighbors, creating a matrix of interconnected points of resistance. Imagine a wall constructed of such stones; the jagged edges grip each other, distributing weight and preventing slippage. This interlocking strength is crucial in applications such as driveway bases or retaining walls, where the stone must withstand significant loads and prevent shifting over time.
-
Enhanced Drainage
The spaces between these angular fragments, the voids left unfilled by smooth surfaces, are not weaknesses but rather channels for water. The irregular shapes create a network of pathways allowing water to percolate through the stone rather than pooling on its surface. This is vital in drainage applications, preventing water buildup that can lead to erosion, frost heave, or even structural damage. Picture a French drain, the aggregate’s angularity allows water to disperse efficiently, protecting foundations from water damage.
-
Increased Friction
The sharp edges and rough surfaces of angular stones provide a high coefficient of friction, a critical factor in preventing slippage and maintaining stability.
