DO THIS IF YOU WANT TO START WITH A STRONG FOUNDATION.
Most building failures don’t start from the roof, they begin underground, at the foundation. If the base of your structure is weak, everything above it is living on borrowed time. Unfortunately, this is where many unqualified quacks take shortcuts.
To avoid disasters and wasted money, here are some vital checks you must not ignore during foundation work:
1. Proper Digging
The trench must go deep enough to reach firm soil. For bungalows, at least 450mm (1feet six inches) is required, while multi-storey houses need about 900mm (3 feet) or more. Never assume the surface soil will carry your load. ( This is usually determined by a structural engineer)
2. Concrete Before Blocks
Laying blocks directly on soil with mortar is a recipe for failure. A proper concrete layer (blinding) must be poured first before blockwork begins.
3. Elevation Against Floods
Your foundation height should protect your home from rainwater or flooding. Don’t only rely on the road level, observe the area’s water flow and neighboring plots.
4. Waterproofing with DPM
A damp-proof membrane (DPM) is your shield against ground moisture. Without it, your tiles, plaster, and finishes will get damaged over time.
5. Strength of Materials
Weak or substandard materials compromise the entire structure. Only use quality cement, aggregates, and reinforcement that guarantee durability.
6. Professional Input
For All buildings, only a structural engineer can confirm how deep and what type of foundation is safe after reviewing soil test results.
The foundation is the heartbeat of your building. Compromising here is like gambling with your life and money. Build right from below, and the rest of your structure will stand strong.
