How To Check The Square

How to check if a form is square

There are several ways to rectify if your walls or concrete forms are being placed square, but let me tell you, this one could be as easy as 3, 4, and 5. Here is the math behind this calculation.

So this is what you have to do:

Mark one wall at 3’

• Measure between points and it should be exactly 5’

The mathmatical formula is:

2. Mark the perpendicular wall at 4’

If is not 5’ you know is not square.

For really long walls, you can apply the same principal with 30’ 40’ should equal = 50’

You can use this method for many applications, so don’t be afraid of using this. It works every time!
