(gÉrÄ­l`É) [Span.,=little war], fighting by groups of irregular troops (guerrillas) within areas occupied by the enemy. When guerrillas obey the laws of conventional warfare they are entitled, if captured, to be treated as ordinary prisoners of war; however, they are often executed by their captors.
The Inside Story â Concrete Is Porous. Most people do not realize that concrete is porous â more porous than Swiss cheese! The pores constitute 12 â 18% or more of the concrete but they are invisible, much smaller than the diameter of human hair. After new concrete is poured, almost half of the water has to evaporate.
Once we grind the surface of the concrete, pores and air holes are opened. The top portion of our polyaspartic /polyurea coating is actually absorbed into the pores of your concrete just like water into a sponge. When it cures, it becomes part of your garage floor, not stuck to the surface as with an epoxy.e grind every garage floor to remove impurities, such as rust, oil, or grease, creating a smooth, flat surface. This also opens pores in the concrete, allowing for our polyaspartic / polyurea coating to be absorbed into your concrete.
