Character from The Coastal Basement
Coastal Basement Services understands the importance of incorporating geologic mapping into your basement waterproofing plan. They will map out every inch of your house from the ground water level to the first floor to identify any buried or uncovered pipes or vents that may pose a threat to your home and its contents. Along with the buried and uncovered pipes, they will also map out the structure of your home from foundation to outer surface. Along with the structure, they will also do a free-site inspection of the exterior to check for any missing or cracked foundation walls, which can weaken the whole foundation. This inspection will also include a thorough evaluation of the soil around the house including any exposed roots, loose surface material or other potential sources of moisture that could get into your basement.
Most contractors will also utilize non-invasive methods of waterproofing your coastal-plain basement. For example, they may use an epoxy paint to conceal any flaws in the ground water, or sump pumps to move excess water away from the house and into a sealed excavation below the house. Most modern day sump pumps utilize pressure equalization to move water away from your home, which helps prevent ground water from rising above the surface of the earth. If the water in your coastal-plain basement is not moving away from the house, it could be due to earth movement underneath the ground.
Types of Coastal Basements Design
Coastal-plain basements are also classified as high-density and low-dense. High-density basement systems have a greater amount of internal space that is exposed to elevated water tables. This type of coastal basement usually has a series of exposed crawl spaces, which connect with a sealed upper level. The walls of the high-density basement are typically concrete, while the floors are made up of plywood and the remaining concrete is either perforated or void. The exposed interior space is covered with sheet rock and a slab of poured concrete.
Low-density coastal basements, on the other hand, have less exposed interior space and utilize concrete walls with plywood floors. These types of coastal basements are not as common as high-density ones. They are used more in low-space residential areas such as apartments. However, they do have more usable floor space and are easier to build. Most low-density coastal basements are two stories in height, compared to three or four stories in case of high-density ones.
Natural soil elevation also plays an important role in determining the amount of space you can allocate in a basement. If your coastal setting is on a slope and the soil slopes at a considerable angle, it will take more vertical space to build in than if the same basement were placed on flat terrain. In such cases, it would be better to use a secant pile wall system to create an earth-level living space in your basement.
Organizing a Coastal Basement Design
The most common design for a coastal setting is a two-level design. A secant pile wall system is first installed above the ground on the first floor level and then connected to a second, lower-level foundation. The wall is set at an approximate angle of thirty degrees to the slope. Secant walls are usually made using materials such as wood, concrete, steel, vinyl or fiberglass.
Determining the location of the bottom wall and the position of the first floor foundation is crucial to the proper construction of a secant wall system. If your coastal basement has no natural ground water access, you will need to dig a hole in the ground for the foundation. Once the foundation is in place, a concrete crib wall system can be installed. Secant pile walls are typically used in wet climates to provide additional protection against flooding.
