To determine how many 25kg bags of ready-mix concrete you need, you will first need to calculate the total volume of concrete required for your project. Once you have the total volume in cubic meters, you can then convert it to the number of 25kg bags needed by dividing the total volume by the yield per bag. Keep in mind that the yield per bag may vary depending on the specific type and brand of ready-mix concrete you are using. It is always a good idea to consult with a professional or the manufacturer to ensure you are using the correct amount for your project. **

Then, line the streambed with a geotextile fabric to prevent erosion and add a layer of concrete to form the desired shape. Finally, finish the streambed by adding rocks, boulders, and plants to create a more natural look and provide habitat for wildlife. **

To design a stream bed with concrete, you can start by creating a form or mold in the desired shape and size of the stream bed. Next, pour the concrete mixture into the form, making sure to smooth and level the surface. You can also add texture or patterns to the concrete to mimic the natural look of a stream bed. Once the concrete has set and cured, you can remove the form and place the concrete stream bed in its desired location, ensuring proper drainage and flow for water. **

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. **
