Garden Before Irrigro®



We are the world's only manufacturer of Micro-Porous Drip Irrigation Systems. Our products are perfect for Home Gardeners, Commercial Growers, and Lanscaping Projects alike. All irrigation tubes are made with durable DuPont Tyvek.

Irrigro.com, home of International Irrigation Systems, was founded by Robert Neff back in 1973. He still owns and operates the company from its original headquarters, in St. Catharines, Ontario.


The evolution of the Irrigro® Drip Tube began in the home laboratory of DuPont researcher Dr. Robert Osborn. Dr. Osborn had been experimenting with a space-age plastic material called DuPont Tyvek®.  He discovered that in addition to having the appearance of paper and the tensile strength of steel, Tyvek® would 'sweat' water under slight pressure. Further investigation revealed that the material's microscopic pores would not clog, making for an exceptional irrigation product.

The Turning Point

Garden After Irrigro®


Dr. Osborn patented his invention, and in passing mentioned his findings to his Chemical Engineer, MBA, and Harvard-Business-School-Accredited son-in-law, Robert Neff. Robert immediately recognized the potential of his invention, and soon after acquired the patents. Trademarks were then registered for the name Irrigro®, and thus the first product of International Irrigation Systems was born.


International Irrigation Systems has been manufacturing and marketing the Irrigro® line of irrigation products for over 30 years, and has continued to achieve significant technological breakthroughs, elevating it to a class all its own.  Improvements in bonding strength, automated pressure compensating water flow controllers, and subsurface conduit have further expanded the applications of this truly miraculous product.  Not only is it used in Home Gardening and Commercial Irrigation, but it is also used today in Greenhouse Irrigation, Waste Water Filtration, Fish Pond Aeration, and is even a key component in the CERN/Atlas Supercollider, located in Switzerland.

Final Words

We're confident that if you invest a few minutes to look through this site, you'll be convinced of the unique merits of the Irrigro® line of products and will want to immediately apply this breakthrough technology to your own garden, landscape or commercial projects.
