Outdoor floor slabs—whether concrete, ceramic, or stone—often collect puddles of water after rain or melting snow. These puddles don’t always drain through the gaps between tiles. Left unchecked, they can take days to dry, leave unsightly stains, or even freeze in winter, creating dangerous slip hazards. Existing drainage add-ons often bend, loosen, or stop working over time as slabs shift slightly.
Core Features of the Invention
This invention introduces a small drainage device that attaches directly to the side of a slab with adhesive. From it extend two tiny prongs (“drainage mandrels”) that rest lightly on the top surface or beveled edge of the slab. These prongs break the surface tension of pooled water, guiding it away from the top of the slab toward the side, where it can drain safely.
Inventive Step
Unlike older designs that were wedged between tiles and easily became loose or deformed, this device moves with the slab because it’s glued to its side. That means the drainage prongs always remain in contact with the slab surface, ensuring reliable water removal even if slabs shift slightly over time.
Tangible Benefits
- Prevents water puddles from lingering.
- Reduces slip hazards and injuries.
- Keeps patios and walkways cleaner and more visually appealing.
- Can be retrofitted to existing patios without removing slabs.
- Discreet design (transparent plastic, slim profile) makes it almost invisible.
Broader Impact
This simple but effective solution improves outdoor safety, reduces maintenance, and extends the life and beauty of tiled or stone surfaces. By making water drainage more reliable, it contributes to safer public and private spaces, especially in climates with heavy rain or freezing conditions.
