Let us calculate the cost of fixing an interlocking paver block for the belowgiven 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 abovegiven calculation of paver blocks, go through the articleðŸ‘‡
❤ 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 ðŸ‘‡
❤ 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.

ðŸ‘€. 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.
