Cement Strip Footings Foundation : Overview
Cement Foundation is not just a recommendation for sectional panel water tanks; it is the most critical factor ensuring the structural integrity, safety, and longevity of your entire water storage system. An inadequate foundation can lead to catastrophic failures, including leaks, panel distortions, and even total collapse.
When installing a sectional panel water tank—whether for potable water, fire protection, or industrial use—the tank itself often gets all the attention. But experienced engineers and contractors know the truth: the foundation determines the tank’s lifespan. even the highest-quality tank will fail prematurely without a proper cement foundation.

Why a Cement Foundation Is Non-Negotiable
Sectional panel water tanks are assembled from bolted steel or FRP panels. Once filled, they exert significant uniform load on the ground beneath. Without a solid, level base:
-Panels may warp or misalign
-Gaskets can compress unevenly → leading to leaks
-Structural stress concentrates at corners → risk of joint failure
-Settlement over time causes irreversible damage
Design Specifications for Export Projects
| Parameter | Recommendation |
| Strip Footing Width | 300mm |
| Strip Footing Height | 500mm |
| Concrete Grade | C25/30 or higher (compressive strength ≥25 MPa) |
| Surface Flatness | ≤3 mm deviation over 2-meter span |
| Reinforcement | Double-layer steel mesh (e.g., Φ8@150mm) or A grid of high-tensile steel rebar (e.g., 10mm or 12mm) at specified spacing is essential to control cracking and provide tensile strength.
|
| Drainage Slope | Optional slight slope (0.5%) for outdoor tanks to prevent water pooling |
| Curing Time | Allow ≥7 days before tank assembly |

Common Mistakes to Avoid
❌ Using compacted soil or gravel as a “base” – not acceptable for permanent tanks
❌ Skipping reinforcement – leads to cracking under load
❌ Installing on uneven or sloped ground without correction
❌ Pouring concrete in rainy or freezing conditions without protection
Conclusion
