Building with Q-Forms ICF

Because each construction project is unique, local codes mandate requirements for foundation footings. However, many local code authorities use the 2018 International Building Codes (IBC) and 2018 International Residential Codes (IRC) as the model codes they modify to suit local conditions and legal requirements.

Utilize a Local Structural Engineer for Footing Design

Many factors determine the design of the footings and foundation. Therefore, it is critical to consult with a local structural engineer to specify the load requirements and footing sizing for the location of the project. A qualified structural engineer is familiar with all the components that ensure strong footings:

Insulated Concrete Forms, or ICFs, are a welcome game-changer in the realm of construction, that are known for their robustness, resilience, and energy efficiency.

This article explores the possibility of using ICF construction if the concrete is poured in stages, as well as the pros and cons of using that method.

Insulated Concrete Forms, often abbreviated as ICFs, are a type of building system designed for enhanced energy efficiency and durability. Essentially, ICFs are modular, interlocking blocks composed of two layers of foam insulation, between which concrete is poured. The blocks act as formwork for the poured concrete, but unlike traditional formwork, they remain in place after the concrete has cured in order to provide added insulation to the structure.

ICFs are predominantly used in the construction of exterior walls for various types of buildings. They are a popular choice for:

• Residential homes: ICFs are ideal for constructing energy-efficient and quiet homes.
• Commercial buildings: Given their resilience and thermal efficiency, ICFs are often used in commercial structures to reduce long-term maintenance and energy costs.
• Institutions: Schools, hospitals, and other institutions benefit from the noise reduction, energy savings, and safety features of ICF construction.

The advantages of ICFs extend beyond energy efficiency and noise reduction. They are highly resistant to fire and extreme weather conditions, which adds to the structural integrity and longevity of buildings constructed using this method.

Pouring Insulated Concrete Forms (ICFs) in stages is a widely practiced and recommended method, mainly owing to the control and precision it offers. The process involves placing concrete in the ICF walls in layers or 4-foot lifts and consolidating of the layers. Below-grade walls must have the concrete placed in lifts continuously to the top of the wall. Above-grade walls, also placed in lifts, may be placed with cold joints.

ICFs required a specific concrete mix design with a higher slump and smaller aggregate. Check with the ready-mix supplier. Typically, the concrete is placed from a pump truck.

The benefits of pouring ICFs in stages include:

• Control: The process offers better control over the quality and consistency of the wall. It also allows for regular checks for alignment and form stability.
• Prevents Form Failure: By limiting the pressure on the lower forms, this method reduces the risk of form blowouts.
• Consistency: It ensures a more consistent curing process, as the entire wall cures at a similar rate.

• Conduct a pre-placement checklist of the walls, alignment, scaffolding and equipment prior to concrete arrival
• Assign the crew with tasks for placement, consolidation, safety and any unexpected problems
• Discuss the placement plan with the pump truck operator
• Conduct a post-placement checklist to align and plum the walls.

Pouring ICFs in stages is a tried-and-true method that can yield high-quality, robust, and consistent walls. Fox Blocks Resource library has concrete specifications, and checklists for concrete placement.
