Preparation is the most important aspect of pouring a concrete slab. Dig the ground down to the proper depth. Smooth out the ground with the flat side of a rake so that you have a level surface. Tamp the ground with a hand tamper or mechanical tamper. Pour 2 inches of small, rounded gravel for additional drainage needs. Click to see full answer. Then, can you pour concrete directly on dirt?Prepare the dirt before pouring concrete. If you are constructing a patio, shed or a sidewalk, the process often starts with pouring a solid concrete base to provide sturdy support. Home owners can accomplish the task themselves by pouring the concrete directly on the ground in the installation area.Subsequently, question is, what do you put under a concrete slab? Whether you pour concrete for a walkway or patio, a strong gravel base is required to prevent the concrete from cracking and shifting. Gravel is especially important in clay soil because it doesn’t drain well, which results in water pooling under the concrete slab and slowly eroding the soil as it finally drains. Also question is, what is the best base for concrete slab? Subgrade and subbase are the foundation of a concrete slab and play critical role in its performance. According to the ACI Code, the subgrade is a compacted and improved natural soil or brought infill whereas subbase is a layer of gravel placed on the top of the subgrade.When should I start watering my concrete?Be sure to start watering the concrete in the morning and keep watering throughout the hottest part of the day. Do not start watering during the hottest part of the day because it could shock the concrete into developing surface crazing (similar to a hot glass breaking when filled with cold water).
