Now that the walls of the basement foundation are poured, the next step is to add gravel to the floor of the basement. So, a huge pile of gravel was added to the job site and then it was spread over the dirt of the basement floor.
The gravel spread under the floor of a basement foundation helps drain any water from under the foundation. It also makes it easier to make the thickness even when pouring the concrete for the basement floor. The benefits of controlling the water and thickness of the concrete are that the basement floor will be more stable in a frost situation and it won’t crack as easily. Now I see why house plans with basement foundations are a more bit tedious, but worth the investment.
Next, we noticed a black substance was added to outside walls of our basement foundation. This tar-like substance will add a layer of waterproofing to the exterior of the concrete. This is the only chance to add this layer, so it’s important to get it on there before the grading of our lot occurs. From what I understand, this tar substance is known by builders to be temporary and if the foundation settles, the material can be brittle and crack. It’s a safeguard builder’s use, but keep in mind, most foundations are going to settle a bit, so the chance of leaks can still occur even after using this product.
However, anything extra to keep from having a flood in your home is worth it. You definitely don’t want to deal with flooding in your home. A flood is devastating and cleanup is a miserable task, so I’m happy to see the gravel put down and the tar added to the walls, so hopefully we’re a bit more protected.
This is exactly the reason why basements are not welcome typically in Southern states or coastal regions and they are never shown as an option with beach and coastal house plans. The shallow water tables are the main culprit for this option not being available. States with a considerable amount of wetland and coastline have too much water under the ground to allow a basement to be built. Thank goodness we live in the Midwest because basements are a secure place offering safety from violent storms and offer a great spot for safe rooms, and they allow for plenty of storage, or expansion area for the future.
