Yes, a concrete patio step does in fact need to be on a footing. Without the proper footing foundation, the step will be uneven.
Also reffered to as 'slab footing' and it consists of concrete footing beams integrated into the concrete floor slab.
Pouring a concrete slab is the pouring of a fresh unset concrete mix into a prepared area, where it is finished by floating etc to give the required surface, and it sets to form a slab.

The necessary steps for properly installing a concrete footing for a retaining wall include: Excavating the area to the required depth and width. Compacting the soil at the bottom of the excavation. Building a form to contain the concrete. Adding a layer of gravel for drainage. Pouring and leveling the concrete into the form. Allowing the concrete to cure before building the retaining wall on top.

The best practices for preparing and pouring concrete for post holes include digging the hole to the correct depth and width, adding a base of gravel for drainage, setting the post securely in the hole, and pouring concrete evenly around the post. It is important to ensure the post is level and plumb before the concrete sets to ensure a strong and stable foundation.

Dry pouring concrete, also known as dry mix concrete, is not typically recommended for construction projects as it can lead to weaker and less durable structures. Wet pouring concrete, where water is added to the mix before pouring, is the preferred method as it ensures proper hydration and strength of the concrete.
Temprature of concrete while pouring at site should be in the range 23 to 28 degree C.

To build a strong footing for your new construction project, you should start by conducting a thorough soil analysis to determine the appropriate foundation design. Next, ensure proper excavation and compaction of the soil before pouring concrete for the footing. Use high-quality materials and follow engineering specifications to ensure the footing can support the weight of the structure. Regular inspections and adherence to building codes are also crucial for a strong foundation.
