Answer : To design a basement wall, you'll need to consider a few factors. The most important factor is the soil type on which your home is built. Other factors include the climate (hot or cold), the weight of the building, and the moisture level of the soil.
You'll also need to decide if you want a poured concrete wall or a cinder block wall. A concrete wall will be more expensive but it will be stronger and longer-lasting. A cinder block wall will be less expensive but it may not be as strong or durable.
Once you've decided on the type of wall, you'll need to decide on the thickness of the wall and whether you want it reinforced with a rebar.
