Foam Instead Of Concrete For Deck Footings

This is not to say alternative products cannot or should not be used in construction.

Foam instead of concrete for deck footings.

Instead of digging footing holes than hauling mixing and pouring hundreds of pounds of concrete you simply use a pad. The foam like i said in the post there were possible issues with maybe the weather or the depth of the hole etc but if the whole point is to beat concrete i still say this failed in that respect. We will teach you how to determine the code compliant size of your footings based on the soil type and tributary loads. No hauling cement bags no mixing no messy pouring no waiting for cement footings to dry.

But make sure the post is treated for ground contact and that you follow these principles for footings. Check out our deck footing frost map to help you understand how deep your footings will need to be excavated. Up from the bottom of the footing. How to get a solid frost proof footing.

Then dump concrete through the tube into the bottom of the hole. Has anybody used post setting foam in place of concrete for post footers. Do this by nailing the sides of the tube to the center of a tic tac toe grid of 2x4s at the top of the hole. Sika postfix is a two component pre proportioned polyurethane resin.

Is this foam replacing concrete. For more information check out this video. When you pour concrete footings hold the cardboard concrete form tube about 12 in. Effectively replaces two 50 lb.

The idea is simple. It s hard to imagine an easier deck footing option than deck footing pads. Bags of concrete mix. And this is why the building codes do not specify high density foam as an alternative to concrete as either a footing beneath a column or to backfill the space between the column and the surrounding undisturbed native soils.

Editors comments yes you can use the new foam that is available to stabilize support posts. It is mixed in the bag to produce expanding foam for supporting and backfilling fence mail box gate and signage posts.
