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.
Talybont
Tal-y-Bont is a small town in Conwy County Borough, Wales and also depends on the Conwy Valley, west of the River Conwy, on the B5106 road, 6 miles from the community of Conwy to the north, and 6 miles from Llanrwst to the south, as well as in the area of Caerhun. It lies adjacent to the town of Dolgarrog to the south, and listed below the little settlement of Llanbedr-y-Cennin to the west. The 'Bont' (the altered form of pont, Welsh for "bridge") in the name most likely describes the bridge over the Afon Dulyn, a tributary of the neighboring River Conwy, which goes through the village. Tal-y-Bont is the beginning point for the roadway to Llyn Eigiau and the southern Carneddau hills. Access to the northern end of the Carneddau Range and also the Roman road over to Aberystwyth can also be achieved by following the road up from Tal-y-Bont with Llanbedr-y-Cennin - which is on the eastern side of the Snowdonia National Park - and taking a left fork at the club, Ye Olde Bull Inn, in Llanbedr. Pedestrians can access peaks in the north end of the Carneddau Range such as Drum and Foel Fras, and afterwards continue southern eastern to reach Carnedd Llewelyn.
