Where can I send my plans to see if my job is suitable for this?
Job and Site Requirements
What types of jobs are suitable for a monopour?
Simple layouts under 300' perimeters with 4-8 corners on a level site are best.
Can I monopour an offset / eccentric footing?
Yes, but you would not attach the Fastfoot forms to the blocks. You would frame the footing with 2x4s and just stand the ICF on the feet inside the footing.
What is the maximum size of a footing that I can monopour?
28 x 12 or 30 x 10, using our widest Fastfoot 74.
Can I monopour 1 row of ICF?
No, you need at least two blocks of ICF to prevent uplift. With one block, there is insufficient material for proper bracing and staking.
Can I monopour steps?
Yes, but it's best to keep steps in multiples of block height, as managing a cut ICF course on a monopour is difficult and wasteful.
Can I monopour ICF in a trench footing?
Yes.
Product and Equipment Needs
What products do you supply for the monopour?
Fastfoot: To form the footings.
Side Supports: To support the block.
Zont Bracing: To brace the walls and stake in position.
What other materials will I need to provide myself?
You will need all your typical forming supplies for example:
- Lumber / Rebar / Concrete
- ICF Blocks
- Tools / Screws / Etc
How many side support feet do I need?
Use a pair of side supports every 4 feet.
You will use an additional pair in every corner, tee, or step.
What ICF blocks can I use for a monopour?
Any ICF block with plastic ties embedded into the foam.
Do I need the Fastfoot corner MP, or can I use the standard corner?
You need the special monopour corner to wrap up onto the block. The standard corner forms the bottom and sides of the footing, while the monopour corner forms the bottom, sides, and top of the footing.
Why do you have pre-sewn tees for monopours but not regular footings?
The Fastfoot Tee needs to wrap up onto the block at the tee and requires a special fabric design. Standard tees for traditional fastfoot footings are simple to make on-site.
Do I need Zont Bracing for a monopour?
Yes. Zonts stake everything in place by offsetting vertical strongbacks 3 1/2" from the ICF using 2x4s.
Steel braces go directly on the ICF and rest on a footing. The footing does not exist yet with a monopour.
Steel braces attach directly to the ICF, there is no room behind the brace to attach the bag to the block.
Pouring Details and Techniques
What slump do I need?
A slump of 5-6 with an ICF mix design for free flow into the footing bag.
On-site plasticizing is likely needed for optimal flow.
Do I need to vibrate a monopour?
Yes, vibrate and consolidate all ICF pours. Make sure the concrete is flowing well into the bag; even gently kicking the bag as it pours can help with consolidation.
How much concrete will I use?
You will use about the same amount as a standard strip footing and wall. However, as they are poured together, you will reduce waste from ordering 2 deliveries.
Extra concrete will be used at the bottom of the bag's bulge, but you will save the same amount at the top of the footing.
There is no leakage or spillage out of the forms.
How do I prevent uplift on the monopour?
Pour the first lift as just the footing and the first 6 inches of the first block.
Our Zont Bracing will stake everything in place. The camlock on the zonts prevent blocks from lifting (make sure to twist counterclockwise as per installation guide).
Maximum monopour height?
We recommend no more than 14' monopours but have seen pours up to 20'.
Your first lift will be the footing and first half of the first block, after that, pour in 3' lifts.
Note: trying to adjust the heights on a heavy 12'+ wall (fully stacked with rebar and bracing on it) can cause the adjustable foot to "punch through" the plastic footpad.
Special Considerations
Can I pour a monopour in winter?
No, you cannot monopour in freezing conditions, as it is challenging to warm the ground around a monopour using heaters and blankets.
Can I pour integrated pads?
Yes, simply frame them out with 2x4s.
Does this blow out?
The fastfoot is designed to handle the pressure and load of the concrete pour, it will not be the failure point unless it is damaged.
Improper installation of the bag to the block can be a failure point. Ensure battens are attached at every web.
