Bugholes are surface voids that result from the migration of entrapped air (and to a lesser extent water) to the fresh concrete-form interface. These surface defects manifest themselves mostly in vertical surfaces.

How To Prevent Bugholes In Concrete?
What causes bug holes in concrete walls?
One of the primary influences affecting the surface aesthetics of concrete are bugholes. Bugholes are surface voids that result from the migration of entrapped air (and to a lesser extent water) to the fresh concrete-form interface. These surface defects manifest themselves mostly in vertical surfaces.
Why does my concrete have small holes?
Air. Air becomes entrapped in concrete during the mixing and pouring process. While some air is necessary to avoid damage when the concrete experiences freezing and thawing temperatures, too much causes blisters or bubbles on the surface that then erupt into holes.

What causes bug holes in concrete surfaces?
Bugholes are surface voids that result from the migration of entrapped air (and to a lesser extent water) to the fresh concrete-form interface. These surface defects manifest themselves mostly in vertical surfaces.
Are holes in concrete normal?
Problem:Small pop outs or holes that occur on concrete slabs are often the result of lignite or shale carbons that were in the sand when the concrete was mixed. The lignite or shale particles are lightweight and float near the surface of the slab when the concrete is installed and troweled.

How do you get rid of bug holes in concrete?
CSA cement seems to have been invented to fill bug holes. It shrinks a lot less than portland cement and it sets a lot faster. I use a mixture of CSA cement, pigment as needed, and a 1 to 1 ratio of Acryl 60 and water. Once you master bug holes, it's possible to achieve a close-to-perfect surface.
