How to calculate the coverage area of interlocking paver blocks? ~ PARAM VISIONS

The interlocking paver blocks are available in numerous varieties having their own pattern, model, & dimensions. Out of them, the 3 shapes of paver blocks that are widely used are,

1. I-shaped paver block.

2. Dumbbell-shaped paver block &

3. Zig-zag patterned paver block.

The manufacturer provides the details & specifications of the paver blocks, to make our calculation work a lot easier. To understand what I said in a better way, go through the article 👇

How to calculate the number of interlocking paver blocks required for any given area?

But, when you purchase the locally manufactured paver blocks, you may need to calculate the coverage area of that particular shape.

So, let us go through the calculation procedure for the I-shaped paver block as shown below.

Area of I-shaped paver block

= [ external rectangular area - 2nos. of trapezoidal area.]

To understand the formula, you can observe the drawing as shown below.

Here, we will deduct the brown-colored trapezoidal portion from the total external rectangular area.

External area

= 160mm. × 200mm.

= 0.16m. × 0.2m.

= 0.032 sqm.

I have redrawn the trapezoidal part for your reference, as shown below.

Trapezoidal area

= [{(side AD + side BC) ÷ 2} × h]

Here, height h

= [(160mm - 120mm.) ÷ 2]

= [ 40mm ÷ 2]

= 20mm.

Trapezoidal area

= [{(120mm.+ 80mm.) ÷ 2} × 20mm.]

= [{200mm. ÷ 2} × 20mm.]

= [ 100mm.× 20mm.]

= 2000 sq. mm.

= 0.002 sq m.

Area of I- shaped paver block

= [ external rectangular area - (2nos. × trapezoidal area.)]

=[0.032 sq m. - (2nos. × 0.002 sq m.)]

=[0.032 sq m. - 0.004 sq m.]

= 0.028 sq m.

The no. of I - shaped paver blocks required / sq m.

= [1 sq. m. area ÷ area of a paver block in sq m.]

= [1sq m. ÷ 0.028 sq m.]

= 35.71 nos.

The no. of I - shaped paver blocks required / sq. ft.

= 35.71 nos. ÷ 10.764

= 3.32 nos.

Let us calculate the number of paver blocks required for 100 sq m. & 100 sq ft. area in a table format.

For 100 sq m.:

Sl. No.	Description.	Area to be paved in sq m.	Pavers required/sq m. in nos.	Total No. of paver blocks
1.	I-shaped paver block	100	35.71	3571 nos.
2.	Add 5% wastage =			178.55 nos.
3.	Total no. of I-shaped paver blocks required=			3749.55 nos.

For 100 sq ft.:

Sl. No.	Description.	Area to be paved in sq ft.	Pavers required/sq ft. in nos.	Total No. of paver blocks
1.	I-shaped paver block	100	3.32	332 nos.
2.	Add 5% wastage =			16.60 nos.
3.	Total no. of I-shaped paver blocks required=			348.6 nos.
