Before laying concrete for a driveway, patio, or any other construction projects it is common practice to first lay a bed of gravel or crush. While it might seem like an extra step, this process is crucial for several reasons.
1. Provides a Stable Base
Gravel acts as a stable foundation for the concrete to sit on. It helps distribute the weight of the concrete evenly, preventing it from sinking or shifting over time.
2. Improves Drainage
Gravel allows water to drain away from the concrete surface, reducing the risk of water pooling and causing damage to the concrete.
3. Prevents Soil Erosion
By creating a barrier between the soil and the concrete, gravel helps prevent soil erosion, which can weaken the concrete over time.
4. Reduces Frost Heave
In colder climates, gravel helps prevent frost heave, which can occur when water in the soil freezes and expands, causing the concrete to lift and crack.
5. Enhances Durability
A layer of gravel helps protect the concrete from damage caused by shifting soil, water infiltration, and other environmental factors, extending its lifespan.
While it may seem like a small detail and an added cost laying gravel or crush down before pouring concrete is an essential step that helps ensure the longevity and durability of your concrete surface. By providing a stable base, improving drainage, and protecting against environmental factors, gravel plays a vital role in this process and should not be overlooked!
