An aesthetically pleasing permeable solution to your driveway, the interlocking nib used in Alpha Flow provides an eco-friendly drainage system, allowing water to filter into a specially designed sub-base.

Alpha Flow possesses the same tumbled edges and classic charm as Alpha, not to mention three popular colour options to express your individuality and coordinate your home’s look.

Available in 60mm single-size packs, Alpha Flow combines the warmth and antique aesthetic of an aged product with forward-thinking permeable technology that will be an investment for years to come.
