Does adding sand to soil help drainage?
Sand is one of the cheapest things you can add to your garden soil that will help to break up the soil. The small particle size of the sand will get in between soil clods and break them up, increase drainage, and help to aerate the soil for good root development.
What is best for drainage?
The stone should be no less than ¾” and dense (we suggest Granite, or River Gravel) so it will allow good water flow. Lime Rock, although inexpensive, is a poor choice for a French Drain because it will begin to deteriorate over time and eventually begin to pack down and restrict flow.

Does gravel help with drainage?

Since the drainage process is expedited when gravel is used at the base of the water body, puddles and wet areas are able to dry out quickly instead of pooling up on top of soil and other land materials.

How much gravel do I need for drainage pipe?

Key Differences While crushed stone is a commercial product created with the use of machines to mine and crush rock, gravel is a product created from natural weathering. Gravel is fragmented rock sourced from deposits of weathered rock found in rivers, streams, and gravel pits.
How does pea gravel help drainage?
Gravel is an ideal drainage solution for two primary reasons — weight and an impenetrable surface. The weight and coverage area provided by the material prevents erosion, and its solid, moisture-resistant design allows water to drain faster. As such, it prevents precipitation from pooling on the surface.
