What is a floating slab?
Floating Concrete Slabs- Floating slabs are concrete slabs that are laying over the ground, without any kind of anchoring, as if it simply sits on it and floats. The main application of floating slabs is to use as a base foundation for sheds, manufacturing workshops, home additional room, or garages. Why Use a Floating Slab?

Individual Reinforcement In Civil Engineering
Here is a video tutorial on how to do individual reinforcement in civil engineering that is featured by Allplan.
What Is Floating Slab?
Floating slab foundations are used in any building where there is a need for low load-bearing for the structure. A floating slab is a form of foundation.
Purpose of Floating Slab
Where there is no need for a deep foundation for a small structure. Float foundation is used there. This type of slab is made over water with no connection between them.
Construction of Floating Slab
Details of planning and commissioning of the proposed building for the construction of floating slabs are collected. So that a strong foundation can be built to fully support the weight of the superstructure.
Disadvantage of Floating Slab
There is no space for a sewage line from this type of foundation. So a trench has to be made for it during the floating slab.
A: Site Excavation for Floating Slab Construction
The initial stage of floating slab construction is to clear the land and excavate the area as per the plan. This is the initial preparation for the construction.
C: Reinforcement for Slabs
The slab mold is placed for casting procedure. To strengthen the slab, the reinforcing bars are provided as per dimensions and codes.
D: Casted Floating Slab
The concrete is poured into the slab formwork. It is compacted either my labor or mechanical vibrator depending on the area and workmanship. Proper compaction has to be undergone, to make the slab fully productive. Proper curing has to undergone for almost 2 to 3 days.
Disadvantages of Floating Slabs
The floating slab does not make underground land available for underground access for connection lines facing the utilities.
What is a live edge shelf?
A live edge shelf is a piece of rustic wood attached to the wall as a shelf.
Basic materials needed to build DIY floating shelves from a live edge slab
If you are looking to make live edge floating shelves, the basic materials you need are:
What wood do you use for floating shelves?
You can technically use any wood for floating shelves. Generally, people choose to use live edge hardwood slabs for floating shelves.
How thick should a live edge shelf be?
A live edge shelf should be at least 1 1/2″ thick, but preferably at least 2″.
How to cut a live edge slab with basic tools
Not everyone has a bandsaw and a planer and a bunch of fancy woodworking tools. However, most people doing a project like this will have a miter saw, table saw and sander.
How to cut thick wood with circular saw
For cutting a board in half, mark the center point on in five or six places on the board, then draw a line straight through those points.
How to use floating shelf brackets
Floating shelf brackets are great for hanging heavy, live edge shelves on the wall.
Pour In Place Concrete Walkways
We chose the more difficult DIY path and enjoyed learning a few things along the way as a first-time project. It turned out no where near the quality of a pro-grade job, but certainly suited the budget. We had previous experience casting our concrete countertops so this project was definitely easier, but still involved a lot of sweat and patience.
Excavating the Ground for Concrete Steps
2x4 planks were laid out to help calculate how many steps and what size to make them. I measured a total rise of 18" from the sidewalk to the landing, and figured that each step would be about six inches. This left me with an option of three steps to get to the sidewalk level, where I would need to put two small pads even with the sidewalk.
Forms for Concrete Steps
Each step was 3.5" thick (standard 2x4 plank), so the first two steps could be simply formed using 2x4s. The three steps up would require 1x6 or 2x6 lumber, because the floating effect required a 2x4 to fill in under the step. Stakes were hammered in to keep the forms in place.
Clean Up the Live Edge
My board was looking pretty good on the top and bottom, but one end was a little ragged. I used my miter saw to cut the slab into two 24" pieces, and kept the ragged end piece to test finishes later.
Buy the Right Hardware
It took a bit of research to find the right floating shelf hardware for these narrow boards. These ones are only 4 ¼" long, so I won't accidentally drill straight through the live edge side! You'll want to use brackets that are at least an inch shorter than the width of your board.
Mark and Drill the Bracket Hole in the Shelf
The position of your brackets depends on the location of the studs in the wall. Unfortunately, the only stud I could use was in the center of the board, so I decided to use wall anchors on the sides instead. I don't plan to put heavy items on the shelves, and the anchors are rated for 75 pounds, so I think I'm good. 🙂
Apply Finish to Shelves (optional)
Now that the sanding and drilling is done, it's time to apply a beautiful finish to the shelves. If you bought prefinished boards like these, you can skip this step and go straight to the installation!
Attach Wall Brackets
The tricky part about any invisible brackets is getting the placement right on the wall. Installing the brackets too close or too far apart, even just by a few millimeters, will prevent the floating shelves from sliding on properly. But this painter's tape trick will help you get it right the first time!
Slide Live Edge Floating Shelves onto the Brackets
Installing these live edge floating shelves couldn't be easier! Just line up the brackets with the holes and slide it on.
