Most decks can be free standing or floating did you know this.
What type of concrete should i use for deck footings.
If your deck is 6 feet or less with proper post to beam and joist bracing it is a perfect candidate for a floating deck.
Concrete footings may also be needed for projects such as a deck pergola retaining wall or other types of construction.
Placement of footings is crucial to provide the proper support for the foundation and ultimately the structure.
Ensure a solid footing.
Outdoor concrete used on home improvements should be ordered with a strength ranging from 3 500 to 4 500 psi.
Make sure you use 5 000 psi concrete mix.
The dimensions of footings also depend on the size and type of structure that will be built.
Your footing should be at least as thick as it is wide at its base.
That said this is one of the more laborious options on this list.
Decks and other permanent structures require deck supports and footings made from structural strength concrete mix.
When non reinforced concrete is used different strengths will be required.
To reduce the risk of shrinkage cracks use sakrete crack resistant concrete mix for projects with concrete thickness of 2 inches or greater.
That is assuming you are using a 4x4 which is 3 5 square.
Which means you must install proper concrete footing foundations that go below the frost line so the deck doesn t move independently in relation to the home.
Fortunately you can buy pre mixed bags of the dry ingredients and add your own water.
It is important to check local building codes for construction requirements in your area.
Concrete form tubes are the footings of choice if you are looking for maximum strength and durability.
It is a professional strength blend of cementitious materials sand stone and fibers that helps eliminate the need for wire mesh in many non critical applications.
Well for each hole you ll need to dig a hole 4 deep and 8 wide.
Once you have poured half of the concrete into the tube you should consolidate it with a shovel or a piece of rebar to eliminate air pocket voids.
You can get away with usually a 15 x15 base and then at least 6 thick so you don t crack the deck footing.
These requirements will include minimum diameter and minimum depth of the footings.
If you are using it on footings and walls a concrete strength of 2 500 psi could be enough while between 4 000 to 5 000 psi is needed for pavements.
For a quick and dirty concrete foundation this method can do the trick.
For an 8 10 freestanding deck you ll need six footings.
Save time and money on concrete with this style.
