The C20 concrete (Gen 3) is a standard-strength concrete grade its minimum compressive strength after 28 days of curing. The compressive strength of the C20 concrete mix is 20MPa (N/mm2) in 28 days. The ratio is as follows:
When we use premixed ballast, the concrete mix ratio of 6 parts is used for 1 part of the cement. The ideal water-to-cement ratio is 55% if all other materials are completely dry. However, in reality, the materials are often damp, especially the sand. In such cases, you may need to adjust the amount of water added.
Owing to its lightweight composition, the C20 / Gen 3 concrete mix contains a high cement content, making it suitable for a variety of applications, such as:

The C20/Gen 3 concrete mix requires 28 days for full curing. After one week, the concrete will have approximately 70% strength. It takes 24 to 48 hours for concrete to set.
Concrete mix design considers several important factors, including strength, durability, workability, the desired appearance of the concrete, and the specific raw materials.
The C20 concrete mix has a strength of 20 Newton per square millimetre in 28 days, making it suitable for lightweight structures like workshop bases, garages, domestic flooring, and foundations. The C25 concrete mix is stronger and is used for heavier structures or larger buildings.
To calculate the amount of concrete you need, it’s recommended to use the standard C20 concrete mix ratio, 1:2:4 (one part cement, two parts fine aggregate, and four parts coarse aggregate). This ratio provides the fundamental mixture for C20 concrete.
A boom pump uses a robotic arm (boom) to deliver concrete with precision at height or distance, making it ideal for large-scale and high-rise projects. A line pump, on the other hand, is better suited for smaller, ground-level jobs and uses flexible hoses to deliver concrete. We offer both types depending on your project requirements.
With a boom pump, concrete can be pumped up to 70 metres vertically and over 200 metres horizontally. Line pumps can reach around 150 metres horizontally, depending on the setup and hose diameter. Our experts will assess your site and recommend the best solution to reach even the most challenging locations.
Yes, it’s important to ensure the site is accessible, level, and free from obstructions. There should be enough space for the pump vehicle to park and operate safely. If you’re unsure about access or clearance, our team can provide advice or arrange a pre-site visit.
The duration of a concrete pumping job depends on the volume and complexity of the pour. In general, a typical residential pour can be completed in under two hours. Our efficient service aims to minimise downtime and keep your construction project on schedule.
Yes, concrete pumps can operate in light rain and mild weather conditions, but heavy rain, high winds, or frozen ground may delay or halt operations for safety reasons. We always monitor the forecast and keep you informed of any possible schedule changes.
Yes, all our pump hires include a trained and experienced operator who will handle the equipment and ensure concrete is placed efficiently and safely. They’ll also help guide you through the process on-site, ensuring a smooth pour every time.
