When excavating house foundations how much more would it cost to use hydro-vacuum excavation rather than traditional hydraulic digging?

Answer 1

The cost difference between using hydro-vacuum excavation and traditional hydraulic digging for house foundations can vary depending on several factors:

Project specifics:

Size and depth of the foundation: Larger and deeper foundations will generally require more time and resources, increasing the cost of both methods.

Soil conditions: Hard, rocky soil might be more challenging for hydro-vacuum, potentially pushing the cost closer to traditional methods.

Accessibility: If the excavation site is difficult to access with large machinery, hydro-vacuum's smaller footprint might be advantageous and cost-effective.

Local factors:

Availability of hydro-vacuum services: In areas with limited hydro-vacuum providers, the cost might be higher due to lower competition.

Labor costs: Different regions have varying labor rates, impacting the overall cost of both methods.

Additional considerations:

Precision and safety: While hydro-vacuum is generally more precise and minimizes the risk of damaging underground utilities, the price difference might be justified for sensitive projects.

Environmental impact: If minimizing dust and noise pollution is crucial, hydro-vacuum's eco-friendly approach might warrant the additional cost.

Estimates:

It's difficult to give a precise cost difference without specific details about your project. However, some studies suggest that hydro-vacuum can be 20-50% more expensive than traditional methods for simple excavations. However, the advantages in precision, safety, and environmental impact can sometimes offset the higher cost, especially for complex projects.

Answer 2

If the question was "can a hydrovac do it", the answer is "Yes". However, since you wish to compare alternatives based on cost, I offer the following comments.

Short answer: Unless there are challenging circumstances (limited access to proposed dig site, existing buried utilities, landscaped property), hydrovac would likely cost more than traditional mechanical excavation methods.

Longer answer: The cost to excavate a house foundation by hydrovac will depend on:

1) Soil conditions

2) Volume to be excavated

3) Rate of production per load (for the particular hydrovac used)

4) Time per load

5) Time to dispose of material

6) Cost of disposal per load

7) Hourly rental rate of the hydrovac

There are many hydrovacs available in the market, however not all hydrovacs deliver the same rate of production (nor do they cost the same).

Also, you could save on restoration costs (compared to traditional means) if the work were to be done at an already developed property. Hydrovacs can work at distances greater than 450' from an excavation site, thereby minimizing the footprint left on existing property.
