Torpedo sand is a type of sand that is commonly used for construction and landscaping projects. It is a coarse-grained sand that is typically a mix of fine gravel, rock fragments, and sand particles.The name "torpedo sand" comes from the fact that the sand grains are shaped like torpedoes or small cylinders. This shape allows the sand to interlock tightly, which makes it a good choice for a variety of applications such as building foundations, creating pathways, and filling in low spots in the yard.Torpedo sand is often mixed with cement to create a strong and stable base for building structures like retaining walls and patios. It can also be used to improve drainage in soil, as it allows water to flow more freely through the soil.Overall, torpedo sand is a versatile and durable material that is widely used in construction and landscaping.
