You should pull up and remove weeds by hand as and when they appear. If it is a regular problem, you might need to reseal the paving. In extreme cases, the sub layer itself may need to be re-laid. You can use weed killer, however some paving can be discoloured by stronger weed killers.
Wingate
Wingate is a town in County Durham, England. Wingate is a former pit village with a mixture of 19th-century, post-war, and also much more recent housing developments. It was originally occupied by around 30 farmers before 1839 when coal was discovered. It is located in the East of County Durham, 3 miles south west of Peterlee, and also 7 miles north west of Hartlepool. Similar to most towns in the location, it grew rapidly with the growth of coal-mining in the area. The name Wingate is stated to originate from the Anglo-Saxon words windig (gusty) and geat (roadway) meaning gusty road. Like all County Durham villages, locals are understood to speak the pitmatic language although new housing developments has actually seen a sharp increase in the village's population. An electoral ward in the same name exists. This ward extends north eastern to Peterlee and also has a complete population, taken at the 2011 census, of 10,302.
