Those of a delicate disposition, please look away now !!!!!!!!!!!!!!!
Toads do not have penetrative sex, they pair up and go to their 'ancestral spawning pond' where the female lays strings of spawn into the water and the male on her back ejaculates sperm over the spawn, which fertilises it.
Your toads are looking for water - have you got an old sink or something you can fill with pondwater for them to use - they might just use it now.
They might wait for you to finish your pond - I don't know - but it needs to have pondweed and plants and mini-beasts in it for the tadpoles to feed on - you could go pond-dipping somewhere and bring some back and add to your pond to start it off but I don't know whether it would establish soon enough to raise a new batch of toads.
