So, if your foundation hole is up to one inch deeper than take mortar mix with the sand, and if your foundation hole is deeper than one inch then buy a mixture with gravel to repair the hole.
But if you are not purchasing it from the store and preparing the mixture yourself, then mix up one part cement with three parts of gravel or sand and mix them with water.
Now wear your gloves and put the bonding material on the surface of the hole and lay it correctly on the whole surface for proper bonding.
Now take a bucket, and pour the mortar mix in that bucket and add water in it mix it well in the water.
Do not pour water one time it is better to add a little amount of water mix it and add more water if required.
While you pour the mortar mix in the bucket and water, there will release dust and debris so make it sure that you have worn all the safety equipment such as glasses, mask and gloves.
While you have added the required amount of water in the mixture, shake it well and keep it going for three to five minutes to prepare a well-mixed mortar mixture.
If your foundation has a small hole, you can pour and spread the mixture on the foundation hole with the help of a putty knife.
But while you are pouring and spreading the mixture first pour it on the corner and deep areas and adjust the mixture with a knife tip.
Once sides and around areas filled adequately with mortar, pour the mixture in the middle surface.
Take a balanced quantity of mixture do not add too much; you can remove the excessive quantity when the mixture is wet.
It is better to fill the patches one by one after drying, but you can also do continuous repairing.
Once you have placed the mortar mix and fill it, make it smooth. You can make it smooth and remove the excessive mixture with the help of a straight board.
Take a board and drag it with its sides to remove the excess mortar mixture. After removing the excess mortar, you will get a better and balanced level with the old concrete level.
If you found some extra mortar, then take a float and remove the other excessive mortar to make all surface smooth and good looking.
Before finishing the task check the patches from all sides to make it sure that level is proper and there is no unbalancing found with old concrete level.
Cover the patches with a plastic sheet to keep them protected from damages.
