FAQ

Frequently Asked Questions

What types of construction can I build with ICF?

ICF wall systems are ideal for above and below grade residential construction and low-rise commercial
buildings, but it’s an excellent solution for multi-story buildings, as well.

How tall can ICF walls be built?

ICFs have been a great solution for low-rise commercial buildings and residential projects for decades now. But there’s really no limit to how tall an ICF structure can be.

By working with a structural engineer, building teams can specify ICFs for taller structures like multifamily residential buildings.

How much bracing is needed for an ICF build?

The standard ICF bracing system includes scaffolding and an adjustable turnbuckle and strongback. 

As always, look to your local building code jurisdiction to ensure that you meet local standards for construction projects.

Should I waterproof a basement?

Waterproofing is recommended for all regions. ICF walls do not prevent groundwater penetration. Dampproofing is only adequate for extremely dry regions where groundwater is not present.

How high can I form and pour at one time?

There are techniques for forming and filling commercial walls 30 feet tall and more. Multi-story buildings are usually formed and filled a story (9-10 feet) at a time, paying close attention to proper concrete placement.

How fast can I place concrete?

Concrete should be placed in 4-foot lifts (passes), at a rate of 8-feet per hour. For an 8-foot wall, concrete is placed in 2 lifts. Approximately 30 minutes after placement, concrete will support its own weight, allowing for the 2nd lift to be placed above it. CAUTION! If concrete slump exceeds 6″ or contains liquefiers, place it in 3-foot lifts, to reduce the risk of a form failure.

How are electrical and plumbing installed in an ICF application?

Wall penetration sleeves should be installed to allow for electrical or plumbing, prior to concrete placement. After concrete placement, you can install electrical wiring or plumbing chases directly into the EPS foam. Just mark a layout of the path that the wire or chases will follow on the wall.

How should interior finishes be applied to ICF?

The interior finishes of an ICF aren’t much different than traditional construction. Drywall or approved interior finishes can be easily attached directly to the wall.

How are exterior applications like cladding or siding attached?

Almost any exterior finish can be used with an ICF system.

Rhino forms are designed with full-length 96″ (8ft) long studs that extend from floor to ceiling with no separations or break-points and embedded in the EPS.

Exterior finishes are attached to the studs within the ICF form. If additional anchorage is needed, concrete fasteners can be used to secure exterior finishes directly to the concrete wall.

How much rebar do I need?

That is determined by local building codes, structural engineers or the generally accepted construction practices for your type of structure.

Do you have ICF technical experts on staff?

At Rhino Form, a technical ICF representative will be assigned to every job to ensure the best experience possible. 

Can I Install this myself as a homeowner?

You can certainly install Rhino Forms yourself. We do recommend hiring a professional though if you don’t have prior construction experience.
