What are excavation services?

Excavation services involve the removal of soil, rock, or other materials from a site, using tools and machinery, to create a space for construction or landscaping projects. These services are crucial for foundations, roadways, landscaping, and more. Professional excavators ensure that the process is done safely, efficiently, and in compliance with regulatory standards.​

What is the purpose of excavation?

The primary purpose of excavation is to prepare a site for construction or landscaping. It involves removing earth to form a cavity or hole of the required size and depth. This process is essential for laying foundations, installing drainage systems, constructing roads, and landscaping. Excavation also plays a vital role in archaeological digs to uncover historical artifacts.

How long does it take to excavate?

The duration of an excavation project by the Radtke team will vary greatly depending on the project's size, depth of excavation, soil type, and weather conditions. Small projects may take a few days, while larger ones could take several weeks or more. Professional assessment and planning are essential for an accurate timeline.

How do you calculate excavation cost?

To calculate the cost of a Radtke excavation service, you will need to take into account several factors: 1.) project size, 2.) depth of the excavation, 3.) soil type, 4.) site accessibility, and 5.) machinery used. Additionally, the cost of the excavation may also include labor, transportation of materials, and any additional services like grading or landscaping. Following the evaluation of your site, we'll provide a detailed quote so you know exactly what to expect for cost.

What must be done before excavation?

Before an excavation is performed, it's essential to have your excavation company conduct a site survey and soil analysis to plan the excavation strategy. As part of this step, obtaining necessary permits and ensuring the site is free from utilities or underground hazards is also important. Lastly, implementing appropriate safety measures for workers and nearby structures will also be a part of this process.

How much excavation can be done in a day?

The amount of excavation that can be completed in a day depends on several factors. These include: 1.) the type of equipment used, 2.) soil conditions, and 3.) the project's complexity. On average, a professional excavation company can move approximately 100 to 200 cubic yards of earth per day. However, this can vary widely based on specific project conditions.
