For decades, gravel-based drainage was the only option. Today, engineered systems like DrenaFast™ outperform gravel on every metric.
Installation time DrenaFast™: 1 day for a 50-meter run. Gravel: 3–4 days with the same crew.
Logistics DrenaFast™: a single van delivers materials. Gravel: multiple truck deliveries, crane access, storage area.
Performance DrenaFast™: stable drainage zone for 25+ years. Gravel: clogging and settling typically begins at 5–8 years.
Cost When labor, logistics and lifecycle are accounted for, DrenaFast™ is the more economical choice for the majority of projects.
When gravel still makes sense Large industrial drainage or very specific geotechnical conditions still favor gravel. For 90% of residential and commercial projects, engineered drainage wins.
