Customers say: Quality work

"Marty and his team were awesome to work with and very professional. On time and the value they delivered was best in class! Neighbors and strangers that pass by have stopped and asked who did our driveway all the time which is a testimonial of their work quality in its self! The swirl design they put created makes our driveway stand out vs. the boring straight brush look you see from most contractors! I highly recommend Marty and Warrior Concrete!!!!!!!"

Excavating FAQs, answered by experts

In the United States, a depth of 36 inches (three feet) for underground water lines is the accepted industry standard. This depth varies from location to location based on local conditions. In areas with colder winters, they may be buried deeper to prevent frozen well water pipes : This is usually at least six inches below the frost level. The International Plumbing Code calls for a minimum of 12 inches below grade.

You do not have to dig footers for a deck as long as it meets local code and holds up to weather in your area. If you live somewhere that experiences high winds and earthquakes, you may need to dig for your deck posts. Deck blocks, post anchors with base plates, and helical pile systems are the three no-dig deck post options you can choose from if local code permits.

Water lines are buried at various depths, depending on the type of line. For example, most sprinkler lines are buried between four and 12 inches underground. On the other hand, water mains usually sit between one and 3 feet below ground. However, they can go even deeper in cold climates to prevent freezing.

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.

The rules for trenching and excavation include setting up and following safety protocols, learning how to use tools and machines properly, and ensuring there is a safe exit for all workers. Keep heavy equipment and materials away from the edge of the hole or trench. Call the 811 dig line before starting any excavation or trenching project to ensure you don’t hit any electrical or gas lines.
