Modulo
VS
Prefab Concrete
Not all prefab pools are built the same.
While concrete pools may appear solid, their rigidity, weight, limited sizing, and installation constraints create challenges that today’s homeowners don’t want to deal with.
Modulo was engineered to solve those challenges entirely.
With a lighter yet stronger steel structure, true design flexibility, multiple size options, and fully customizable exterior finishes, Modulo delivers a modern prefab pool experience that concrete simply can’t match.
And even though both systems use a PVC membrane interior, the difference lies in everything underneath — from structural performance and adaptability to long-term durability and architectural possibilities.
Here’s how Modulo compares to prefab concrete pools.
Structure & Durability
| Criteria | Modulo (Steel + Reinforced PVC Membrane) | Prefab Concrete |
| Structural Material | Industrial-grade steel | Concrete shell (rigid, brittle) |
| Strenght & Stability | Flexible + robust | Strong but rigid |
| Crack risk | None | High in feeze/thaw or soil movement |
| Impact Resistance | Very high | Medium |
| Weight | Light (easy transport & crane) | Very heavy (costly crane & access limits) |
| Anticorrosion | Epoxy-coated steel | Concrete prone to microcracks & degradation |
Interior Finish
| Criteria | Modulo (Reinforced PVC Membrane) | Prefab Concrete (PVC Membrane) |
| Membrane Tickness | 3x thicker than standard inground pool liners | Similar, depending on brand |
| Waterproofing | 100% waterproof | 100% waterproof |
| Repairs | Easy (replace membrane only) | Easy (membrane), but concrete structural cracks harder |
| Comfort | Soft & pleasant | Same (membrane) |
Installation & Flexibility
| Criteria | Modulo | Prefab Concrete |
| Installation types | Above ground, semi inground, inground | Above ground, semi inground, inground |
| Installation on pile | ✔ Possible | ✘ Not possible |
| Base options | Stone or slab | Stone or slab |
| Installation time | Tipically 1 to 3 days | Tipically 1 to 3 days |
| Relocatable | ✔ Yes | ✘ Not built to relocate |
| Interior Modules | 8 options + custom configurations | Fixed shape (1 permanent module only) |
| Skimmer placement | Fully flexible | Fixed position |
| Available Sizes | 12+ size options | 3 - 4 sizes |
Climate Resistance & Maintenance
| Criteria | Modulo | Prefab Concrete |
| Freeze/Thaw Behavior | Excellent | High crack risk |
| Maintenance | Low | Higher (concrete aging) |
| Pet-Friendly | ✔ Yes | ✔ With membrane |
| Visual Aging | Membrane and siding upgradeable | Membrane ugradeable but concrete ages (outside) |
Aesthetic & Customization
| Criteria | Modulo | Prefab Concrete |
| Look & Style Options | Wide variety | Limited |
| Ability to Refresh Interior Look | Replace membrane | Replace membrane |
| Exterior Appearance | Modern, architectural | Plain concrete box (industrial) |
| Exterior Siding | Compatible with any siding; some can be pre-assembled before delivery. | Not designed for siding; site-built modifications required |
