The cost of fixing interlocking paver blocks./ Rate analysis of paver block flooring.

 Let us calculate the cost of fixing an interlocking paver block for the below-given drawing.



Given data:

Flooring area = 20 ft. × 18 ft.

Sand bed thickness = 2" = 0.166 ft.

Cement mortar thickness = 3" = 0.25 ft.

Cement mortar depth = 4.5" = 0.375 ft.


A. Material calculation:

1. Paver blocks:

The number of paver blocks required = 1044 nos.

To observe the above-given calculation of paver blocks, go through the article👇

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


2. Sand:

The volume of the sand bed

   = length × breadth × thickness

   = 20 ft. × 18 ft. × (2 ÷ 12 ) ft.

   = 60 cu ft.


3. Cement mortar:

   = [(flooring periphery)  × depth × thickness]

  = [(2nos. × 18 ft. + 2nos. × 20 ft.) × 0.375 ft. × 0.25 ft.]

  = [( 36 ft. + 40 ft.) × 0.375 ft. × 0.25 ft.]

  = [ 76 ft. × 0.375 ft. × 0.25 ft.]

 = 7.125 cu ft.


Let us make the cement mortar in a 1:4 ratio.

Cement required /cu ft. of mortar =0.217 bags.

Sand required/ cu ft. of mortar   = 1.064 cu ft.

Note:  The above data is extracted from my article 👇

 Calculating the quantity of materials in 1 cum. & 1cuft. of plastering mortar in different mix ratios.

Cement required for preparing the mortar

  = total mortar vol. in cu ft.× cement / cu ft.

  = 7.125 cu ft. × 0.217 bags

 = 1.55 bags.


Sand required for mortar

  = total mortar vol. in cu ft.× sand / cu ft.

  = 7.125 cu ft. × 1.064 cu ft.

 = 8.19 cu ft.


So, the total vol. of the sand required for paver installation

  = [for sand bed + for cement mortar]

  = [60 cu ft. + 8.19 cu ft.]

  = 68.19 cu ft.


B. Labor calculation:

The labor rate for the paver fixing inclusive of mechanical floor compaction ranges from INR 10/- to INR 16/- per sq ft.

Let us consider the average rate of INR 13/- for the calculation purpose.

The total cost of the labor

   = total area × rate / sq ft.

   = 360 sq ft. × 13/-

   = INR 4680/-


Now, let us calculate the cost of fixing the interlocking paver blocks in a table format.

 👀. What are interlocking paver blocks? - their advantages & disadvantages.


1.  The cost of paver flooring / sq ft.

   = [The total cost of paver installation ÷ total flooring area]

   = [INR 27,533.67/-  ÷ 360 sq ft.]

   = INR 76.48 / sq ft.


2. The cost of paver flooring / sq m.

  = [the cost/ sq ft. × 10.764]

    (As 1sq m. = 10.764 sq ft.)

 = [ 76.48 × 10.764]

  = INR 823.23 / sq m.
