Q: How deep can a trench be without protection?

• <div><p>A trench that is less than 5 feet deep often doesn't require a protective system. Most residential trenches will not go this deep (the typical residential drainage trench is just 18 inches deep). In the event that an excavator needs to dig more than 5 feet beneath the surface, a protective system is required unless the excavation is in entirely stable rock. </p></div>

Q: Why is slab more affordable than a crawl space?

• <div><p>Slab foundations are more affordable than crawl spaces because they require minimal excavation, as the slab sits directly on the ground or on footers that only sink a few feet into the ground. Crawl spaces require excavation of the entire footprint of the home to several feet below the surface. Not only does that mean higher labor costs, but more materials are necessary for the concrete foundation walls. </p></div>

Q: How far should you bury downspouts from the house?

• <div><p>Downspouts should be buried at least 5 to 10 feet away from your foundation. This can vary depending on your local building codes, soil type, and property slope. The main goal is to ensure water is directed away from your foundation.</p></div>

Q: Can you make your basement deeper?

• <div><p>If you don&rsquo;t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less&mdash;between <b>$40,000 and $90,000</b> on average. However, if you&rsquo;re not adding new finished square footage, you won&rsquo;t see much in the way of ROI.</p></div>

Q: How deep are septic lines buried?

• <div><p>Septic drain lines (or leach lines) are typically buried between 18 and 36 inches underground, and should be at least 6 inches below the surface. These pipes are perforated and surrounded by filtering materials like sand or gravel. Burying the lines at this depth helps minimize odors and allows bacteria and other biological processes in the soil to effectively treat the wastewater. Burying lines too close to the surface can cause issues unless the soil is very compact and stable.</p></div>
