1. General comparison between Concrete Foundation and Hi-Foundation
| Description | Concrete Foundation | Hi-Foundation |
|---|---|---|
| Shape |  |
 |
| Pad material | Plain concrete + Steel liner | STS pipe + SMC |
| Build | Moulding-Concrete pouring -Curing-Mortar plaster-Curing |
Bolt assembling |
| Leveling | Poor horizontality (Non-precise standing of skid base) |
Precise horizontality (Precise standing of skid base) |
| Durability (Strength) |
Good compression strength, but instabilities for curing, plastering & liner |
Standardized Uniform Quality with more than 8times safety ratio (Ready made product) |
| Corrosion resistance |
Rust on steel liner Concrete corrosion |
No rust (Anti corrosion material) |
| Pad weight reduction / 300 places |
165,600kg (100%) | 3,600kg (2%) |
| Build time / 500 tons |
More than 30days | Less than 3days |
2. Structural design and stability verification
SERIM HI-FOUNDATION is a proven product that has undergone a field test for a scientific design and compressive strength test by FEM and a 7 meter high water tank.
3. FEM analysis result
HI-FOUNDATION generation stress
Stiffener (Steel)
197kgf/cm² < 1600kgf/cm²
(Allowance rate 8.1 times)
Stiffener Plate (SMC)
17kgf/cm² < 212kgf/cm²
(Design Margin 12.5 times)
4. Field Test
| Water height | Skid base deflection | Spec (KS Standard) |
|---|---|---|
| 7mH | 1.25mm | Less than 10.0mm |
| Maximum deflection 1.25mm (strain safety factor 8 times) |
