What are you building?

No construction knowledge needed.
1. How a house is built (tap each part)
2. Foundation
Material & spec: RCC strip footing, mix 1:2:4 (1:1.5:3 for heavy / seismic), Grade 60 bars. Use SRC cement in salty or waterlogged soil. Depth must be confirmed by soil test.
Why it matters: The foundation spreads the building's weight on the ground. Never cut corners here — you cannot fix it later.

2. Steel bars: Grade 60 vs Grade 40
- ✔ Grade 60 is 50% stronger, so the same load needs less steel and the columns stay less crowded.
- ✔ Hazara / Haripur is an earthquake region: use Grade 60 for columns, beams and slabs. In an earthquake the steel must be strong AND stretch without snapping.
- ✔ Only buy mill-certified bars. Avoid scrap or re-rolled steel — it is brittle and can snap suddenly.
- ✔ Grade 40 is only for minor items (lintels, small rings) in low-rise houses outside high seismic zones.
3. Concrete mix: how much cement, sand and crush
Standard RCC: slabs, beams, columns, lintels (≈3000 psi)
Mix 1:2:4: 1 part cement : 2 sand : 4 crush
Measuring box (thaghar / gauge box): make a wooden box 12" × 12" × 15" = 1.25 cu ft = exactly one 50 kg bag of cement. Use the SAME box for cement, sand and crush — count the boxes.
So one bag of cement needs 2 boxes of sand and 4 boxes of crush.
Use clean water, not too much — extra water weakens concrete.
4. Sand & crush: which one where
- ✔ Use clean, coarse Lawrencepur sand for concrete; fine sand is for plaster only. Muddy sand weakens concrete — wash or reject it.
- ✔ Crush should be angular, clean and between ½" and ¾". Use ½" in thin slabs and lintels, ¾" in columns and footings.
5. Why the DPC (damp-proof course) is a must
Bricks and mortar are full of tiny pores, like thin tubes. Without a DPC, ground moisture is pulled up the wall (up to 3–4 ft) and brings salts that spoil plaster and paint. A DPC at plinth level breaks this path — it costs very little compared with repairing damp walls later.
