01 / CHOOSING
1
HOW DO I KNOW WHICH POCKET FORM ISOLATOR IS RIGHT FOR MY JOB?
3
It comes down to three things: the plan dimensions of the blockout, its shape, and its depth.
↓
HOW DO I PICK THE RIGHT PLAN DIMENSION?
Look at the architectural or engineering requirements; the base plate's shape, size, rotation and location; the minimum concrete cover from the base plate to the edge of the blockout; and how you want the finished floor to look.
WHAT'S THE BEST SHAPE FOR AN ODD SITUATION?
Start with the standard PFI shapes. If none of them fits, we can manufacture a custom one.
WHAT DEPTH SHOULD I ORDER?
Usually the distance from the top of the footing up to finished floor elevation (FFE). Where columns bear on piers, there is often some room to choose.
02 / INSTALLATION
WHAT IS THE POCKET FORM ISOLATOR ANCHORED TO?
Usually the footing. On some pier projects it can be staked on compacted fill. It can also be anchored to walls, footings or stakes. Perimeter blockouts often need wall anchorage, and many are attached to temporary edge forms.
03 / ORDERING & LIDS
HOW CAN I BE SURE I'M ORDERING THE RIGHT PFI?
Call or email the sales team. There are over 1,600 shape and size combinations, and more than one may fit your job. We'll help you pick the best one.
DO LIDS COME WITH MY ORDER?
No. Not every project needs lids, and leaving them off can save you money.
WHICH PROJECTS DON'T NEED LIDS?
Projects where the columns go up before the blockout forms are placed.
If the blockouts are set before the slab is cast and the columns come later, lids pay off: finishers don't have to work around open holes, and the lids help you meet OSHA open-pit rules. Open column blockouts can bring serious OSHA fines, especially before the columns are up.
