Building with insulated concrete forms can simplify construction in many ways. The lightweight, stackable design means they can go up faster than traditional concrete forms. However, there are some common mistakes builders make. This post will cover mistakes to avoid when installing ICF forms.
7 Mistakes to Avoid When Installing ICF Forms
Poor Planning and Design
Inadequate planning can cause problems during ICF construction. You should work with an architect or designer with expertise in ICF construction. They can help you plan your layout, including where doors, windows, plumbing, and electrical systems will go. With proper planning, you can avoid many common issues and reduce waste.
Incorrect Block Alignment
Misalignment of ICF blocks can compromise the structural integrity. Use alignment tools and often check that the blocks are level and straight. Focus especially on corners and openings, where alignment problems are more common. Fixing alignment issues while building the formwork is much easier than afterward.
Using the Wrong Concrete Mix
Not using the correct concrete mix can damage the walls and structural integrity of the building. Each ICF manufacturer specifies the correct concrete mix for their forms. Learn the correct mix for the forms you are using and adhere closely to those guidelines. If you are unsure, you can contact the manufacturer for help.
Not Using Enough Fasteners
Some builders might try to save time and money by using fewer fasteners. Not using the correct number of fasteners can reduce durability and lead to early repair costs. Using the correct number and type of fasteners is crucial. If you’re unsure which fasteners to use, seek advice from an expert.
Ignoring the Roofline
Builders often make a common mistake by leaving a gap between the roof, the air barrier, and the insulation. This mistake can compromise the project’s thermal efficiency. Focus on getting the roofline right during installation to prevent any mistakes leading to such gaps.
Excessive Use of Cantilevers
Cantilevers can complicate ICF projects because they increase the load on the walls. ICF construction works best with straightforward wall designs. If you can, eliminate or minimize the use of cantilevers. When they must be part of the design, pay special attention and plan for extra support and bracing.
Failure To Do Proper Research
Building ICF walls without proper knowledge or research is a beginner’s mistake. Proper research helps you determine which forms to use and what mistakes to avoid. It also helps you find the best material suppliers.
