Where do I take the boulder once it’s removed?

• <div><p>After you successfully remove your boulder, you have a few options for what to do to get rid of it. You can rent a dumpster if your yard has many boulders or if you’re planning a larger project. You can even save the boulder and reuse it elsewhere on your property to save on <a href="https://www.angi.com/articles/how-much-does-landscaping-cost.htm">landscaping costs</a>. A few ideas include using the boulder as a natural, abstract statue, breaking it into smaller pieces to line your garden bed, or offering it to a landscaping company that could reuse it for another project.</p></div>

Can you make your basement deeper?

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

How deep should a trench be?

• <div><p>Trenches are 12 to 24 inches deep and 8 inches wide. However, the right depth for your trench will depend on the nature of your project. For example, if you’re digging a trench as part of a <a href="https://www.angi.com/articles/french-drain-installation.htm">French drain installation</a>, it should be 18 inches deep. An excavation professional can explain how deep your trench should be. </p></div>
