For setting lawn edging stones, garden concrete would be the better option. Garden concrete is specifically designed for outdoor use and is more durable and weather-resistant than concrete screed. It also has better adhesion properties, making it more suitable for securing the edging stones in place. Additionally, garden concrete is often formulated to be more resistant to cracking and shifting, which is important for maintaining the integrity of the lawn edging. **

To pour concrete garden paths, you will first need to prepare the area by clearing it of any debris and leveling the ground. Next, create a form using wood or metal edging to contain the concrete. Mix the concrete according to the manufacturer's instructions and pour it into the form, spreading it evenly with a trowel. Allow the concrete to set and cure for the recommended time before removing the form and finishing the surface as desired. **

Organic farming practices can be more sustainable than conventional methods in terms of reducing chemical inputs, promoting biodiversity, and improving soil health. However, there are challenges to the scalability and efficiency of organic farming, which can impact its overall sustainability. For example, organic farming typically requires more land and labor to produce the same amount of food as conventional methods, which can limit its ability to meet global food demand. Additionally, the transportation and distribution of organic products can have a higher environmental impact due to their shorter shelf life and the need for refrigeration. Overall, while organic farming has many sustainable benefits, there are also limitations to its long-term sustainability on a large scale. **

For a garden, you may need concrete for various purposes such as creating pathways, building retaining walls, or setting up a foundation for structures like sheds or gazebos. The type of concrete you need will depend on the specific project requirements, but generally, a standard concrete mix with a strength of 3,000 to 4,000 psi should suffice for most garden applications. Additionally, you may need additional materials like rebar or mesh for reinforcement, depending on the project's scale and complexity. **

To apply concrete on concrete, the existing surface must be clean, free of debris, and properly moistened. A bonding agent or primer should be applied to the existing concrete to ensure adhesion. The fresh concrete mix can then be poured or pumped onto the existing surface and spread evenly using a screed or trowel. It is important to properly cure the new concrete to prevent cracking and ensure a strong bond between the two layers. **

Yes, it is possible to pour new concrete over old concrete as long as the existing concrete is in good condition and properly prepared. The old concrete should be clean, free of any loose debris, and roughened to provide a good bonding surface for the new concrete. Additionally, a bonding agent may be used to ensure a strong bond between the old and new concrete. It is important to consult with a professional to assess the condition of the existing concrete and determine the best approach for pouring new concrete over it. **

Concrete with a minimum strength of 20MPa is typically used for a garden fence foundation. This type of concrete provides the necessary durability and stability to support the fence structure and withstand outdoor elements. It is important to ensure that the concrete is properly mixed and poured to create a solid foundation for the fence. Additionally, reinforcing the concrete with steel rebar can further enhance its strength and longevity. **

To pave a garden path with concrete, start by preparing the area by removing any existing vegetation and debris. Then, create a form for the concrete by using wooden boards or metal edging to define the edges of the path. Next, mix the concrete according to the manufacturer's instructions and pour it into the form, using a trowel to smooth and level the surface. Allow the concrete to cure for the recommended time before removing the form and adding any desired finishing touches, such as a brushed or stamped texture. Finally, seal the concrete to protect it from the elements and ensure its longevity. **
