How to Measure the Terrace ? Easy Method
Step 1: Measure the Terrace Length and Width
Most terraces are rectangular or square in shape. Use a steel tape or laser measure to note down the length and width in feet.
Example:
Length = 50 feet
Width = 25 feet
Step 2: Apply the Basic Formula
The formula for terrace area is simple:
Area (sq ft) = Length × Width
Example Calculation:
50 ft × 25 ft = 1,250 square feet
Step 3: Subtract Obstructions
Many terraces include features like water tanks, staircases, or solar panels. Measure the footprint of these obstructions and subtract them from the total area.
Example:
Staircase area = 80 sq ft
Tank base area = 20 sq ft
Net Terrace Area = 1,250 – (80 + 20) = 1,150 square feet
Step 4: Add a Safety Margin
For waterproofing, always include an extra 5–10% to cover joints, edges, and overlaps. This ensures complete coverage and prevents leaks.
Why Accurate Calculation is Important
Cost Efficiency – Prevents over-purchasing or under-purchasing waterproofing materials.
Better Planning – Helps contractors estimate labor and project time.
Long-lasting Results – Proper material coverage means stronger, leak-proof protection.
