Waterproofing Calculator
Estimate waterproofing material for roofs and wet areas in Pakistan.
About the Waterproofing Calculator
Numbers should not slow you down. The Waterproofing Calculator does the arithmetic for you and shows the result live, so you can focus on the decision rather than the maths.
Building a house in Pakistan means budgeting in rates per square foot for grey structure, finishing and utilities — and those rates move with material prices. This Waterproofing Calculator estimates your construction cost from the covered area and current per-square-foot rates, so you can plan a realistic budget before you break ground.
The calculation applies the grey-structure rate and finishing rate to your covered area, with optional allowance for labour and contingency. The result is a total that matches how Pakistani contractors actually quote — per square foot of covered area.
Rates vary by city, specification and time of year. A 2025 benchmark is roughly Rs 1,800–2,500 per sq ft for grey structure and Rs 3,200–4,500 per sq ft for a complete house, but the calculator's rates are inputs so you can use your contractor's actual quote.
Construction budgets routinely overrun by 10–20% due to material price hikes and design changes during the build. Add a contingency of at least 10–15% to the estimate here, and update the rates monthly while construction is ongoing.
Use the Waterproofing Calculator as often as you like — it is free, needs no account, and pairs well with the other calculators in this category for a fuller picture.
How to estimate construction cost
- 1
Enter the covered area in square feet (or marlas if the tool accepts it).
- 2
Enter the current grey structure rate per sq ft.
- 3
Enter the finishing rate per sq ft and any contingency percentage.
- 4
Read the total estimated cost, updated live, and add 10–15% buffer.
Frequently Asked Questions
How much does construction cost per square foot?
In 2025 Pakistan, grey structure (structure + roof) runs about Rs 1,600–2,200/sq ft and complete finish about Rs 3,200–4,500/sq ft depending on materials and city.
How much does construction cost per square foot in Pakistan?
In 2025, grey structure runs roughly Rs 1,800–2,500 per sq ft and a complete house Rs 3,200–4,500 per sq ft, varying by city and material quality. These rates are editable in the calculator.
How much does a 5-marla house cost to build?
