DIY Crack Repair

This used to be a small opening in the cement screed on the driveway slab outside the main gate. It started life as a 12 cm dia hole. Then after two weeks the 12 cm dia. hole gradually turned into a big gaping hole measuring 25 cm x 25cm. It is definitely getting too big to ignore. 

Working with the wife we patched up the hole using a paint scraper with a small quantity of cement paste mix that we procured from a friendly Indonesian worker who was mixing cement sand paste in a nearby house that is under renovation. We asked only for a small quantity but received more than our request.  After patching up the hole we then leveled the side of the driveway slab with the excess cement paste .
