Q: How deep can you dig for a basement?

• <div><p>Most residential basements are 8 to 10 feet deep. You can dig deeper depending on building codes, but it does become more difficult. You&rsquo;ll likely need to install stronger foundation walls and additional supports to handle the increased load. Depending on the water table, you may also need a water management system. Clay soil can support a deeper foundation than sandy soil. A structural engineer will be able to tell you the maximum, feasible depth.</p></div>

Q: How deep are sewer lines buried?

• <div><p>Sewer lines can be buried anywhere from 18 inches to 8 feet deep, with a common average depth between 18 and 30 inches. The exact depth depends on local factors like climate and soil type. In colder regions, pipes must be buried deeper (below the frost line) to prevent freezing, sometimes as deep as 8 feet. The digging depth can also impact the cost of sewer line replacement. To find the specific depth for your property, you can check the building plans for your system, which should be on file with your city or local sanitation department since permits are required for installation.</p></div>

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: Is it OK to dig through tree roots?

• <div><p>Tree experts don&rsquo;t advise against digging through tree roots, but instead encourage caution and consultation with a local arborist to make sure you don&rsquo;t damage the tree&rsquo;s structure or interrupt its water or nutrient intake. An arborist can recommend specific practices when digging and help prune the roots or dig a trench for utilities with a tool that can remove soil without touching the tree&rsquo;s roots.</p></div>

Q: Can excavation be done in the winter?

• <div><p>Yes, you can <a href="https://www.angi.com/articles/can-you-excavate-in-the-winter.htm">excavate in the winter</a>, but it might make the job harder. Frozen ground is harder to dig, and snow or ice can make the work site more hazardous. A contractor may need special equipment and techniques, such as ground-thawing methods, to break through frozen soil. Although winter excavation is possible, it may take longer and be more costly than excavating during warmer months.</p></div>

Kimball and Fredy did our install. They were efficient, professional and the work came out beautifully for our bath to shower conversion. Morgan was the sales coordinator and did a top notched job of explaining everything to us and getting us a good price. Excellent experience, all around.
