Use a good quality cement and push the cement in as far as you can, if it a thru-hole, do the same on the inside, smooth one or both patches flush. If its below ground level apply a "Tar base material" to the patch after the cement dries, this will help in waterproofing the patch.
If the hole is clear of the concrete get a little bit of pipe 25mm or an inch and cut it along the length so that you have a ring that opens up. Get some PVC primer and PVC solvent cement . use the primer to clean the outside of the pipe with the hole in it and the inside of the patch. put solvent cement on the pipe around where the patch is going. stretch the ring so it opens up and covers the hole and hold it in place. you can do this with a suitable hose clamp. wait a couple of hours before use. if you can reach the inside of the pipe you can use a similar procedure,
Yes, but the walls of the hole may contaminate the cement. Mixing the cement may be very hard, and precarious. Further, you may not be able to remove all the cement from the hold afterwards. It is more advisable to use a cement-mixer.
You can plaster a wall with Portland cement and fine sand mixture. Polymers are plastics and I've found nothing on using them in a mixture to plaster a wall.
Balanced cement plug is pumped through drill string or open-ended tubing. 'Balanced Cement Plug' means that the top of cement outside the drillstring/ tubing will be the same height as the top of cement inside the drillstring at the end of pumping. The drillstring/ tubing is then slowly pulled from the wet cement, allowing the cement inside the string to fill the centre of the plug. There are lots of refinements in this method with open hole cement retainers or high viscosity 'cushions' often placed below cement. In vertical hole, most balanced plugs are successful. In extended reach wells, failure rates can be high with cement slumping and mixing with synthetic based muds. A typical checklist to improve cement plug success in extended reach wells would have: 1. Always use a tailpipe. This reduces the disruption to the plug caused by removal of the drillstring. 2. Clean up the hole thoroughly before pumping cement. Cement is an excellent hole cleaner. Many 'flash set' events reported are really packoffs caused by cement picking up a cuttings dune. 3. Put a diverter tool with BIG holes on the bottom of the tailpipe. This directs fluids up the hole during cementing 4. Use a scavenger spacer in front of the cement job to convert the formation from oil wet to water wet. 5. Slow down pumping to 1 BPM while displacing cement into open hole. This reduces mixing of cement and mud. 6. Put a cushion below the cement plug. A cement retainer is best. If a viscous cushion is spotted, weight the cushion to 1 ppg below the cement weight. 7. Gravity is NOT on your side. Cement can stay inside the tail pipe as you pull it from the plug. Pump the volume of cement inside the tailpipe as you pull the tailpipe from the plug. 8. Circulate clean the long way with the bottom of the tailpipe at the planned cement plug top.

To patch a hole in a wall, you will need to clean the area around the hole, cut a patch of drywall to fit the hole, apply joint compound to the edges of the hole, place the patch over the hole, and then smooth out the joint compound.

To patch a wall effectively, start by cleaning the area, cutting a patch to fit the hole, applying joint compound, smoothing it out, and letting it dry before sanding and painting.
To effectively patch a hole in your roof, you will need to clean the area around the hole, apply roofing cement or sealant to the hole and surrounding area, and cover the patch with a piece of roofing material. Make sure the patch is secure and watertight to prevent further damage. It is recommended to consult a professional roofer for larger or more complex repairs.
To effectively patch a small hole in a wall, you will need to clean the area around the hole, apply spackling compound or patching plaster, smooth it out with a putty knife, let it dry, sand it down, and then paint over the patched area to match the rest of the wall.
To effectively patch a hole in drywall, you will need to clean the area around the hole, cut a patch of drywall to fit the hole, secure the patch in place with drywall screws, apply joint compound over the patch, let it dry, sand it smooth, and then paint over the patched area to match the surrounding wall.
