After being in the paving industry for over 30 years I was excited to have the opportunity to install the new Marshall's driveline drain,after only using aco drains in the past, first thing I noticed was the robust construction of the units, the installation was simple and straightforward the units are easy to handle and install to a string line, they are supplied with all the accessories you need to connect to existing drainage or soak away installs,we installed the charcoal drains on a pennant grey and charcoal border Driveway which looked really good when finished they blended into our installation fantastically, we will be incorporating the new driveline drains into all our future installations, Thank you Marshall's for bringing something new into the market which makes our installs definitely more pleasing to the eye. 👍 Regards Brian BR paving.
