If I need to join two pieces of wood to make the overall length of a
pergola longer than each individual piece of wood , would a half lap
join be the correct method ?

If so how do i stop water getting in between the joints ?

In addition would coach bolts be a recommended method to ensure the
horizontal pieces did not move from the vertical posts?

Thanks

This joint will not be as strong as unjoined single bit. I buy floor
joists for this type of activity, most builders merchants deliver.
