"This company has been the best landscaping company to work with in my area. They came in to install plants, lawn, slate paths, drainage, and did a total overhaul of my old broken-down irrigation system. Steve?s expertise and craftsmanship has made our outdoor space come alive again. The only contractor that actually showed up on time for our appointments!"

"Dan came out right away and gave an estimate on replacing our 2 car driveway. We decided to expand the side yard to make a 4 car driveway, and he accommodated the day of the start of work. Gave us an awesome price! He and his son were here 3 days, and finished everything. They are clean, professional and friendly. I would recommend Ultimate Concrete to anyone! They do other types of work as well. Thank you Dan!"

Excavating questions, answered by experts

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.

Because decomposed granite is a durable material, a crushed rock or gravel base is optional as long as the DG is properly installed and compacted. However, installing a base is a good idea because it will ensure proper drainage and stability and act as a weed suppressant (although you may still occasionally have to pull weeds). Installing an adequate base can also increase the durability of driveways and walkways. If you forego the paver base or gravel underneath, line the area with landscaping fabric to avoid weeds.

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.

The cost to repair a crawl space runs between $1,500 and $15,000, depending on the extent of the damage. Major flooding or water repairs can cost up to $10,000 for removal and repairs. If you simply need to clean your crawl space, expect to pay between $2,000 and $6,000 for a major cleanout. Replacing a crawl space beam due to rot or damage can cost between $1,500 and $5,000, while removing and replacing damaged insulation costs between $1,000 and $4,000.

Directional drilling is complex and requires training to use the advanced machinery. It can be challenging to monitor the position of the drill since there’s no direct line of sight. Directional drilling can also be more expensive with a cost of $10 to $30 per linear foot compared to $5 to $12 per linear foot for trenching.
