"Very Well. We can’t say enough about H-Bros excavating! When we approached Marcus to come bid on our job. We were impressed. He seemed to know what he was talking about and told us we would need a D6 or D8 cat to rip all the rocks from the area we wanted flattened. He said he could probably get it done with a D6 and quoted it for that. He ended up bringing a D8 which worked out great since it could rip the rocks a lot faster. To our delight we got done 2 days early. Marcus and team started the job on schedule, were on time each day and worked hard and long hours. They were very professional and very personable. They wanted to make sure that they did the job exactly how we wanted it done. Customer satisfaction was very important to them. They went above and beyond our expectations and we are extremely happy with their services and would recommend them to anyone! They were a pleasure to work with and very honest. Do not hesitate to call them for your excavating needs! They may be a newer company but they are worth it!"

Excavating questions, answered by experts

Trenches are typically 12 to 24 inches deep and 8 inches wide. However, the required depth depends on the specific project and local ordinances. For example, a French drain may need to be 18 inches deep, while a water pipe might require a depth of 24 inches and a drainage pipe 36 inches. Your city or county may have specific regulations, so it's wise to consult with an excavation professional to determine the correct depth for your project.

You can dig 60 to 80 linear feet by hand per day depending on the depth. Digging a 100-foot trench by hand will take you two work days, but it can take longer if you have heavy or rocky soil. If you’re digging a deep trench or one that’s over 100 feet, consider renting a mechanical trencher, such as a walk-behind or ride-on, or calling a pro for help. 

Yes, you can excavate in the winter, 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.

Concrete blocks are the cheapest way to base a shed. However, the space in between allows critters to go under, burrow, and even damage your shed’s frame. For a more pest-proof option, consider building a shed base with gravel or paver stones. Both options are fairly affordable and easy enough for a DIY project. For gravel, you can build a wooden frame to contain the loose material.

A mini excavator can dig between 5 and 11 feet deep, depending on the type and size of the mini excavator. Mini hydraulic excavators are more powerful and can reach deeper into the earth, but electric models have a more limited range. Mini excavators over two tons in size are also more powerful and able to dig as deep as 11 feet.
