Covalent bonding is like a tug-of-war. Two atoms share their electrons, but each atom pulls those shared electrons towards itself. When the two atoms pull equally, it is called a nonpolar covalent bond. Atoms form bonds in order to achieve a stable, full outer energy level.For most atoms this means having eight electrons in the outer energy level, like the noble gases.ovalent bonding is like a tug-of-war.

One of the most typical causes of basement flooding is that the house has been constructed on an unsuitable site. Houses are usually built on sloped terrains, allowing accumulated water to drain. If your home has been built on the low part of your estate, chances are it will flooded frequently.
When the old clay and concrete perimeter drain tiles collapse, roots and dirt clog the drain; the basement has no drainage protection and the basement floods. Basement and floor perimeter drainage is essential for protection of your house or building foundation.he groundwater is pushed into the drain system and not into areas where it can damage carpets, walls or belongings. The water drains by gravity into a sump pit where a sump pump discharges it out of the house. There are two basic types of drain systems for wet basements.
