Precast concrete molds are pretty much just what they sound like: concrete that is cast ahead of time into reusable molds or forms designed ahead of time. These are usually done in a controlled environment, transported to the site where they will be used, and lifted into place as desired (known as tilt up). Frequently used in construction, precast concrete molds differ from standard concrete pours that pour the concrete on site usually into different molds specific to the site and then cured on site.

  • Stronger and more efficient. Precast concrete is specifically designed and constructed to have a high span-to-depth ratio, meaning it can bear loads better. This reduces the need for support columns within the interior of the building. Since it’s lighter, the structural material can be smaller and the foundational depth reduced. Precast concrete’s overall strength allows it to be durable for many, many years. Internally, it’s resistant to all kinds of scraps, dings, cracks, chips, and bangs from bumps here and there.
  • Cheaper than standard concrete pours. Precast concrete products are manufactured off-site and are delivered ready to install. This innovative process shortens project schedules, increases safety, reduces site disruption, and saves on overall project costs by requiring less manpower and contractors.
  • Sound control. Because of concrete’s density, precast buildings absorb sound, making it an ideal choice for commercial and residential buildings. This denser concrete reduces vibrations that move throughout the building, which is ideal for projects such as concert halls. The acoustic nature of precast concrete allows for noise from the outside such as road noise to bounce away from the structure, while reflecting the noise inside toward the center of the structure. This is perfect for restaurants and homes so conversation and music can be heard.
  • Environmentally-friendly. Precast concrete forms last forever, eliminating the need for more material in the future. There is less waste because of the preciseness of the precast concrete process. Less material is required in the overall manufacturing of precast concrete such as less need for soundproofing. And because we are using molds, these molds can be used over and over again. Precast concrete is also 100 percent recyclable at the end of its life.
    Stand up to the elements. Studies have shown precast concrete can withstand flood damage, high winds, heavy rain, and freeze-thaw cycles better than other construction and building materials.
  • Thermal efficient. Since precast concrete is denser and less of a thermal conductor, heat is more stable throughout the building. This type of concrete is slow to react and easier to heat or cool relative to external and temperatures. Costs associated with heating and cooling can be greatly reduced through concrete’s thermal mass benefits. Reduced peak heating and cooling loads can be achieved because concrete reacts slowly to changes in outside temperature.
  • Resistant to chemicals and rust. Precast concrete has become the go-to material for docks, bridges, overpasses, and more because interlocked precast concrete blocks maintain their resistance to oil, chemical spills, and fuel spills. Water and rain is less likely to cause rust. Also, for precast concrete forms that are in the water such as bridges, many of the microbes in waterways known to cause decay are less effective, thus improving safety as the internal steel and rebar are not exposed. If damage does occur to precast concrete, only the damaged panels need to be replaced.
  • Fire resistant. Due to the nature of concrete synthesis, precast concrete forms are fireproof when installed and manufactured correctly. Precast concrete doesn’t catch fire, won’t burn, and doesn’t drip. This allows for the occupants to stay safe. If a nearby fire does affect precast concrete in some way, it would most likely be merely cosmetic and simply require a new coat of paint to restore the aesthetic value.
  • Pest resistant. Critters like soft material. Precast concrete as we’ve seen is anything but soft. Rodents also like material they can chew such as wood.
  • Low Maintenance. The exterior of a precast concrete structure can be left unpainted without damage from the rain, wind, or snow. If you did paint the precast concrete forms, repainting would only be needed every five to ten years. Precast concrete form interiors are not subject to weather conditions and thus are less likely to be damaged. Interior precast concrete forms are also easier to wash.
  • Quality control. Since precast is manufactured in a controlled casting environment, it is easier to control the mix, placement, and curing process, and to monitor it as well. Strength and uniformity also comes from this quality control.
  • Wi-Fi friendly. Due to the more porous nature of precast concrete forms, Wi-Fi and other Internet networks can pass through more floors or walls, further decreasing the overall cost of the businesses housed inside the structure. This is one of the chief reasons precast concrete has started to show up in schools, homes, office parks, hotels, restaurants, and small stores.

Precast concrete molds are superior to regular concrete pours. The very nature of having something pre-made saves time, effort, and money and makes the planning process for construction companies simpler. Plumbers, electricians, and utility companies all benefit from using precast concrete molds. The ability to control the entire process from start to finish — from materials to consolidation to curing — cannot be overstated as the strength gains are immense. Furthermore, having a form that is repeatable is the best way to maximize economies of scale for businesses and individuals alike.
