Mae'r concrit wedi cael ei wythnos gyntaf ers i mi osod y swp olaf. Rydw i wedi darllen bod dydy e ddim yn gwbl galed tan 28 diwrnod ar ôl dodwy, ac mae'n gallu parhau sychu ar gyfradd o fodfedd y mis. Felly rydyn ni angen gadael fe i sychu tan y flwyddyn newydd cyn gwneud rhywbeth a allai atal anweddiad. Mae'n ddiddorol dysgu pethau fel hyn. Rydw i'n meddwl bod rhaid i mi roi tipyn bach o sment ar ffin y concrit nawr i atal glaw a phryfed rhag mynd i mewn.

The concrete has had its first week since I installed the last batch. I've read that it's not completely hard until 28 days after laying, and it can still dry out at a rate of an inch an month. So we need to let it dry until the new year before doing something that could prevent evaporation. It's interesting to learn things like this. I think I have to put a little bit of cement on the concrete edge now to stop rain and insects getting in.
