Am posting again as I can't see my previous one.
Soakers on Interlocking tiles have to be laid over the top of the tile and a book I've borrowed shows the soaker in one length covering several tiles and dressed into the tiles profile.
Q: Rather than using one long length of lead, is there any reason why each "over tile soaker" can't be laid to the length of each tile + 25mm overlap to the top with the top 25mm snipped on the upstand crease to form a straight hook over the tile to secure the soaker?
Many thanks Greengrass.
