Concrete or tarmac driveways
Weeds have a tendency to take hold wherever there is a free spot! They use every crack to take root and develop, and it is generally very difficult to get rid of them properly.
When a weed starts growing in a crack in the concrete or tarmac driveway, the roots worm their way in wherever they can, and grow with a force that can quickly destabilise the concrete or tarmac driveways by distorting them, making them permeable, etc. The weeds that are visible are only the tip of the iceberg, and over a period of time can cause irreparable damage.
There is a simple solution: a ready-to-use Roundup Path Weedkiller for Patios, Driveways and Terraces. This driveway weedkiller gets right to the roots of the weeds, allowing them to be properly eradicated, even in the narrowest cracks.
Gravel driveways
Weeds that infiltrate gravel driveways create unsightly patches. Techniques exist to limit the growth of weeds before a gravel driveway is laid: you can erect a tarpaulin that will stop vital elements such as light or moisture from reaching the weeds.
Unfortunately, using this technique necessitates some work before the driveway is laid. If the driveway is already in place, regular weeding is important, especially at the beginning of the season when weed growth is still short.
For this type of weeding you can use one of Roundup's Drive Weedkillers for Patios, Driveways and Terraces, that is ready to use and that will eliminate all weeds right down to the roots.
