Learn about the Precast Concrete Manufacturing and Installation Process

Precast concrete is a construction product made by pouring concrete into reusable molds, which are then transported on-site for installation. The molds are typically made from steel, wood, or other materials that can withstand the pressure of wet concrete.

Precast concrete companies specialize in the production of precast concrete products, such as septic tanks, water tanks, cisterns, oil separators, well casings, manhole covers, light basins, and other building components, as well as custom and decorative work. We have the expertise and equipment needed to produce high-quality precast concrete products that meet the specific needs of your construction projects.

The process of precasting concrete involves several steps, including:

  • Design: We work with engineers to design the product to meet the project's specifications.

  • Molding: The mold is created based on the design, and the concrete is poured into the mold.

  • Curing: The concrete is left to cure and harden in the mold, which can take several days.

  • Finishing: Once the concrete has cured, the product is removed from the mold, and any finishing touches, such as smoothing or texturing, are applied.

  • Transport and installation: The precast concrete product is transported to the construction site and installed using specialized equipment and techniques.

Precast concrete products offer several advantages over traditional cast-in-place concrete, including faster installation, better quality control, and reduced on-site construction time. There are also numerous advantages over plastic products, such as durability, strength, and stability. Precast concrete companies play a crucial role in the construction industry by providing high-quality precast concrete products that meet the specific needs of construction projects.

Great Experience


i had a great experience in dealing with  Dans Precast. i had to lift and move a septic tank to a lower level and the whole process went very smooth. The driver (cliff i believe) was very professional,  thoughtful and friendly and very easy to deal with .

i had to coordinate the lift after i had pumped the tank. Ernie (in the office) was able to coordinate a lift time that worked out for all of us.

i will use Dans Septic in the future for sure. do not hesitate to call, they have a newer crane truck that can lift all kinds of things...just call them and talk to them about your needs....Great job and thank you again, jim
