Hydraway Versus other Drainage Systems

There are several French drain options available on the market today. However, none compare to the compressive strength, guaranteed results, and as shown in the video below, in-flow rate. Flow ratings are only a measure of how quickly water flows from the pipe. A more important question to ask is, “what is the in-flow rate?”

Helitech’s Drainage System Hydraway VS Perforated Pipe

Below is a photo of a failed perforated pipe system (left) that has been clogged and caved in because of its lack of strength. Hydraway (right) has high composite strength due to its polyethylene core. Hydraway’s unique design allows for 85% available open space for water intake. Take a look at the chart below for more comparisons between traditional perforated pipe drainage and irrigation systems, and the industry-best Hydraway system.
