Should I build a crawl space foundation or a full basement? Building a crawlspace foundation may save money on the initial construction cost compared to a full basement, but not necessarily time, as they can take about as much time to build as a full basement foundation. Most realtors will tell you that the basement is the area of a house that will return the most money per square foot at the time of sale. A new basement living area can also create that much wanted entertainment room, family den or needed extra bedroom and bathroom combination. Finishing a basement is absolutely the least expensive way to generate more livable space. I already have a crawl space foundation. Is there anything I can do to change that? Basements converted from crawl spaces are a common solution when space and land are a concern. We can transform your crawl space into a basement while you are living in the home, so that means no need to move out during construction! Concrete Poured Walls vs Concrete Block Concrete block foundations over time can bow, settle, crack and are more susceptible to water leakage through their joints. At the same time they are unsightly when they are left unfinished! If the concrete block foundation isn't filled with steel rebar and concrete then it will be weak, structurally unsound and have little insulation value. Poured concrete walls are joint-free and typically 8-12 inches thick which makes them denser, stronger, drier and fire resistant which is crucial for basement walls. They can better withstand cave-ins created by lateral pressures from the ground, water and wind. Basements using poured concrete walls also provide an outstanding place to keep your family safe during natural disasters. Colorado, Wyoming and Nebraska all have their high wind areas. Basements are excellent for anchoring a property to the ground while extending the foundation below the area’s frost line, which helps maintain the integrity of the foundation over time.There is nothing more durable and safe than a concrete wall! Extremely versatile, poured concrete foundations can accommodate any foundation floor plan.
