Yes and no. They leave the steel casing in the hole, and usually fill it with lean cement.
If the hole is very small the material you are brazing with should fill it. A small piece sheet metal can be brazed in place to cover larger holes.
Cement mixed with water, sand (gravel) - in other words more concrete.
difference between engineered fill and non engineered fill material
to fill the emptiness i think.
"Cut and fill" refers to the practice of excavating soil to make a hole in the ground and then refilling it later. The extracted material tends to increase in volume as it is no longer subject to the in-situ stress or in other words, the soil that has been dug up gets bigger because it isn't being squashed any more by the weight of soil surrounding it.This means that the volume of the hole or excavation will be smaller than the pile of material excavated and so you would have to squash (this process is more correctly described as consolidation and compaction) the soil to make it fit back into the original hole it came from.Therefore the volume of the cut material (the hole) must be considered separately from the volume of the fill (the pile of earth or soil removed).
Holes don't fill things up, they empty it
Fill them up again.
I used plumber's putty to fill the holes. It stays soft and maleable. That might work for you too. Plumber's putty will not allow you to paint or stain. If you need either of those abilities you need to use a latex exterior wood filler/putty or a urethane based caulk that stays flexible and is paint and stain accepting. You can also use wooden dowel rods, found at hardware and home improvement stores, cut to length (approximately 3/4 inch long) with wood glue to fill simple holes.
Bondo.
First, a hole was drilled into a piece of amber that contained a fossilized insect in it. The hole was drilled into the abdomen of the bug and any possible DNA was removed with a needle. Once DNA was obtained it was analyzed to determine species and fix any missing gaps which were repaired with avaian, amphibian, or reptile DNA to fill in missing holes. Once a sample was generated it would be interrupted at the cellular mitosis level and inserted into an unfertilized crocodile ova. The ova were then placed into synthetic eggs and incubated for around two months and then bam! A baby dinosaur.
steel mesh. the mesh is unpleasant to bite, or claw through, so they go elsewhere.

With a concrete crack filler
It will cover them and maybe fill them in a little but you should fill them in with food filler first.
Fill dirt is dirt that someone has removed from one area and needs to dump somewhere else. Often this is dirt that has been removed so that a swimming pool can be installed or excess dirt from clearing land for construction. There is clean fill dirt, which does not have trash, plant material, rocks or chemical additions and this is preferred for reuse in yards for planting.
to improve drainge In the area that I live in, some people use sand as a filler to fill holes in their grass area that has been removed by erosion. It works, but is not the best thing to use. Sand has nothing to offer except volume of soil for the roots for the grass to grow in. Its just a substitute for topsoil.
There are two reasons for holes in a football helmet. Helmets have always had holes drilled in the crown area for ventilation. Body heat accumulates inside the helmet, especially during strenuous activity, and must be able to escape. The newer modern helmet styles have larger and better placed ventilation holes designed to keep the player from overheating. The second reason for holes in a helmet shell is for access to the air bladder fill points. Most modern football helmets incorporate air filled padding, which have one or more insertion points for a needle to add or release air to conform to the players head.
