The Science of Drainage Matting
How Hollow Drainage Mats Work:
- Rapid Water Dispersal: 20mm drainage holes allow water to pass through immediately - prevents surface pooling and slip hazards
- Debris Clearance: Large holes allow dirt, leaves, and debris to fall through - keeps walking surface clean and clear
- Air Circulation: Hollow design promotes air flow underneath mat - speeds drying and prevents mold/mildew growth
- Raised Walking Surface: Hollow pattern elevates feet above water level - keeps feet dry even in flooded conditions
- Self-Cleaning Action: Water flow through holes washes away contaminants - maintains hygiene with minimal maintenance
Proven Performance Benefits:
- 95% faster drainage than solid mats
- Prevents slip-and-fall accidents in wet areas
- Reduces cleaning time by 50%
- Maintains dry, safe walking surface
- Prevents water damage to underlying floors
- Improves hygiene in wet environments
Hollow Drainage Mat vs Other Solutions - Comparison Guide
Hollow Mat vs Solid Rubber Mat: Hollow design drains 95% faster and stays cleaner. Solid mats trap water on surface. Choose hollow for wet areas and superior drainage.
Hollow Mat vs Wooden Decking: Rubber mat is non-slip when wet and requires no maintenance. Wood becomes slippery and rots. Choose hollow mat for safety and longevity.
Hollow Mat vs Plastic Grid: Rubber is more comfortable underfoot and provides cushioning. Plastic grids are hard and uncomfortable. Choose hollow mat for comfort and anti-fatigue.
Hollow Mat vs Concrete: Rubber provides drainage, cushioning, and warmth. Concrete is hard, cold, and slippery when wet. Choose hollow mat for safety and comfort.
Installation Guide
Surface Preparation:
- Clean existing surface - remove debris, dirt, and standing water
- Ensure surface is relatively level (minor undulations acceptable)
- No base work or ground preparation required
- Can be laid on concrete, wood, grass, gravel, or compacted earth
Mat Installation:
- Position Mats: Lay mats in desired location starting from one corner
- Butt Edges Together: Place mats edge-to-edge for seamless coverage
- Cut to Fit: Trim edges using straight edge and utility knife for custom fit
- No Fixing Required: Weight of mats keeps them in place - no adhesive needed
- Optional Securing: For high-movement areas, use double-sided tape on edges
Installation Time: Average 10m² area takes 30-60 minutes for DIY installation
Maintenance & Cleaning
- Daily (High-Traffic): Hose down to flush debris through drainage holes
- Weekly: Pressure wash or scrub with mild detergent and water
- Monthly: Lift mats and clean underneath if needed
- As Needed: Remove trapped debris from drainage holes with brush
- Winter: Remove snow and ice - mat remains flexible in freezing temperatures
- Longevity: Regular hosing maintains drainage efficiency and extends 10-15 year lifespan
Safety & Compliance
Slip Resistance: Hollow raised pattern provides excellent grip in wet conditions - reduces slip-and-fall accidents by up to 80% compared to smooth wet surfaces.

Frequently Asked Questions
What is a hollow drainage mat used for?
Hollow drainage mats are used for wet areas requiring rapid water dispersal and anti-slip safety. The 20mm drainage holes allow water, liquids, and debris to pass through, keeping the walking surface dry and safe. Perfect for pool decks, wet rooms, outdoor decking, commercial kitchens, and any flooded or damp area.
How fast does hollow drainage mat drain water?
Hollow drainage mats drain 95% faster than solid mats thanks to large 20mm diameter holes. Water passes through immediately, preventing surface pooling and maintaining a dry, safe walking surface even in heavy rain or flooding.
Can hollow drainage mats be used outdoors?
Yes! Hollow drainage mats are perfect for outdoor use. The weatherproof rubber withstands rain, snow, frost, UV exposure, and temperature extremes (-20°C to +60°C). Ideal for pool decks, outdoor decking, patios, and muddy areas.
Are hollow mats suitable for pool decks?
Absolutely! Hollow drainage mats are one of the best solutions for pool decks. They provide anti-slip safety when wet, drain water rapidly, resist chlorine exposure, and provide comfortable cushioning for bare feet. Widely used in residential and commercial pools.
How do I clean hollow drainage mats?
Simply hose down or pressure wash - water flushes debris through the drainage holes. For deeper cleaning, scrub with mild detergent and water. The self-draining design makes maintenance quick and easy.
Can grass grow through hollow drainage mats?
Yes! When laid on grass, the 20mm holes allow grass blades to grow through. This makes hollow mats perfect for muddy gateways, field entrances, and garden paths - protects ground from erosion while maintaining green appearance.
Do hollow mats provide anti-fatigue comfort?
Yes! The 23mm cushioned hollow design provides good anti-fatigue relief for standing workers. Suitable for commercial kitchens, bar areas, workshops, and workbenches where staff stand for extended periods.
How long do hollow drainage mats last?
With proper care, hollow drainage mats typically last 10-15 years in wet area applications. The heavy-duty rubber construction resists wear, UV degradation, and chemical exposure, maintaining drainage efficiency throughout lifespan.
Can hollow mats be cut to size?
Yes! Use a straight edge and sharp utility knife (Stanley knife) to cut mats to custom sizes. The rubber cuts easily, allowing you to fit mats around obstacles, corners, and irregular shapes.
Are hollow drainage mats suitable for commercial kitchens?
Yes! Hollow mats are excellent for commercial kitchens. They provide anti-slip safety in wet conditions, drain spills rapidly, offer anti-fatigue comfort for chefs, and are easy to clean. Widely used in restaurants, catering facilities, and food processing.
