How a Site Pad Protects Your Home
Proper site pad development is essential. If helps ensure that your slab is properly installed and protected. A good slab has solid compacted area that will not shift, is level and is raised above the surrounding area to keep water from collecting around or entering your home.
Choosing an experienced grading operator is one of the most important factor in getting a quality house site pad. Don’t cut corners to save money on site preparation and pad construction. If a house builder arrives at the site to begin construction and finds that the pad and site preparation are inadequate, it can delay the project and become an unplanned expense. If poor pad construction is not detected before the house is build, house settling, erosion and flooding are some of the problems that will be a serious cash flow drain for years until corrected.
Land Clearing — Remove stumps
It is important for all the stumps and vegetation to be removed. You don’t want these root balls to be under your pad. They will eventually decompose and create a void under your slab, compromising the structural integrity of your house.
The area is deep raked to remove organics.
We scrape off 4–6 inches of topsoil from the pad area, plus an additional 5–8 feet beyond the pad area. Scraping off the topsoil eliminates the highest percentage of vegetation and organics.
Some contractors take short cuts and won’t use enough loads of dirt for the pad. If you want to take short cuts on your house, don’t do it on the pad. You can’t redo your pad later.
Select fill is imported and compacted where your house pad will be built. The select fill is spread and compacted in 4–6 inch lifts to maximize the efficiency of compaction.
We shaped the topsoil up to the pad to give it a nice even taper on all four sides. Usually we recommend building the pad at least 10–12 inches higher than the highest natural grade elevation that meets the pad. So, when you’re ready to place a 12-inch form board for your slab, it will have 20–24 inches to taper and shape the dirt around your structure. This taper will redirect water around your structure.
This pad—built by someone else—originally didn’t have enough taper on the side of the house. Daniel Dean imported dirt to give it a nice gradual slope away from the house add to the integrity of the pad.
