Back Water Valves
Oftentimes, opening a hole inside your basement floor to set up a backwater control device will expose groundwater in areas having a high water level or recent large rainfall.
Water won't hurt the exterior of the backwater valve, but can allow it to be difficult to examine your valve. In this case, a sump pit could be excavated and the sump pump installed to pump out standing water and lower the water table below your own basement floor. A sump pump is generally used to get rid of water that has accumulated inside a water collecting sump hole or sump crock. Water will accumulate within the sump pit whenever rainwater or organic ground water is greater than the pit.
Sump Pump InstallationsPlumbing codes in many municipalities specify which sump pumps shouldn't be connected to the actual sanitary sewer. Another line should be set to the front ditch or other suitable water course.
Pumps are often dependant on the home's electrical program, and some sump pumps possess a battery backup. Since a sump hole may overflow unless constantly pumped, a backup system is essential for cases once the main power has gone out for prolonged amounts of time. The two main forms of battery backup sump pumps are, Pedestal Sump Pumps & Submersible Sump pumps.
Pedestal sump pumps and submersible sump pumps differ in that the pedestal sump pump's engine is mounted over the pit, where it's more easily serviced but tends to be a bit louder when operating and much more visible. The submersible sump pump motor is entirely mounted within the pit, and is specially sealed to avoid water from getting into its electrical circuits.
Choosing the best back water valves or sump pumps for your home really depends on the connectivity in your home's electrical system and best location on site.
One of the most common methods of waterproofing is called Positive side waterproofing. This is done on the same side of a structure that has its main source of water. The reason for this is that it prevents any structural damage right at the source before it has a chance to enter your building.
Negative waterproofing although not as common is done on the opposite side on the interior of the structure. This is usually done for things like remedial work, elevator pits and tank liners. Waterproofing can be done before the structural walls are laid as well. This is called Blind Side waterproofing. Typically cannot be accessed once the structure is complete.
