Beam Pockets and Blockouts
Creating a Beam Pocket
- Determine the proper placement height of bearing plate and size of the beam. Consult your engineer.
- Cut out foam and web ties to accommodate beam size.
- Brace the back side of the beam pocket well with 3/4 plywood or 2×4 scabbing to support the back foam panel once the web ties are removed.
- Reuse the cut-out portions of EPS foam to bulkhead the sides of the pocket or create small bucking from wood to hold back concrete on both sides of the beam pocket.
- Secure the bulkheads/bucking with adhesive foam and/or screws to prohibit movement during the pour.
- If a bearing or weld plate is needed at the base, insert it after you have poured the concrete and the pocket has slaked but is still workable.
- It is critical the height of the beam pocket is correct.
- On solid foam, cut slightly larger than the beam pocket size, secure and pour in place.
Note:
Beam pockets and placement will impact other trades such as framers and truss engineering. During the plan review stage, ensure the location is noted and planned for. If you suspect by examining the plans that you may need to install a beam pocket, communicate with trades and engineering to obtain specifications and placement. Add these locations to your pre-pour checklist.
