Frequently Asked Questions
What is the process for pouring a concrete foundation?
The process for pouring a concrete foundation typically includes the following steps:
- Excavation: The first step is to excavate the site where the foundation will be poured, including removing any grass, rocks or debris.
- Footings: Once the site is excavated, the next step is to create the footings, which are the base layer of the foundation. The footings are typically made of reinforced concrete and they support the weight of the walls and the structure above.
- Forms: The forms are the molds that will be used to pour the concrete. They are typically made of wood, steel, or plastic and are set up to the dimensions required for the foundation.
- Rebar and Wire Mesh: Reinforcing steel bars (rebar) are installed to provide additional strength to the foundation and prevent cracks. In addition, wire mesh is installed to help distribute the load evenly.
- Pouring the Concrete: Once the forms, rebar, and wire mesh are in place, the concrete is then poured into the forms. It is important to monitor the concrete during this process to ensure it is evenly distributed and there are no air pockets.
- Finishing the Concrete: After the concrete is poured, it will be smoothed and leveled. This process includes using tools to screed and finish the surface, making sure it is level and the finish is smooth.
- Curing: The final step is to allow time for the concrete to cure or harden for several days. During this time, it should be kept damp to prevent cracking and ensure proper strength.
Once the foundation is fully cured, the rest of the building process can begin.
What is concrete flatwork?
Concrete flatwork refers to any kind of flat, horizontal surface made of concrete. This can include sidewalks, driveways, patios, floors, and other structures. Concrete flatwork is typically poured on-site and then finished, smoothed, and leveled using various tools and techniques. It is a durable and versatile material that is commonly used for its strength, durability, and low maintenance requirements.

What is concrete pumping?
Concrete pumping is the process of using a machine to transfer liquid concrete through hoses or pipes to a designated location on a construction site. The process involves placing the concrete mixture into a hopper, which is connected to a series of pipes or hoses. A powerful pump system is then used to push the concrete mixture through the pipes or hoses to the desired location, where it is then poured into forms or directly onto the construction surface. This method of concrete placement is often used in large construction projects, where access to the site is limited or where the construction site is at a significant height above the ground. It is also commonly used in projects where the concrete needs to be delivered quickly and efficiently, such as in the case of emergency repairs.

What materials are used to make concrete?
The most common materials used to make concrete are cement, water, aggregates (such as gravel, sand, or crushed stone) and supplementary materials (such as fly ash or slag). The ingredients are mixed together to form a paste which hardens into a strong and durable construction material.
How long does it take for concrete to cure?
The curing of concrete can take anywhere from several days to a few weeks, depending on factors such as temperature, humidity, mix design, and local weather conditions. Generally, concrete will achieve its maximum strength after 28 days of curing, but it may reach a usable strength level in as little as 24 hours. It’s important to follow the proper curing procedures to ensure the best possible durability and long-term performance of the concrete.
