No Dig?

FFI offers the no-dig system of fence instillation but what exactly does it involve? The no-dig fence process is gaining popularity for its simplicity and efficiency. Instead of excavating large holes, this method utilizes metal posts that are pounded into the ground using specialized equipment. These posts often come with a sleeve and bracketing system for easy attachment of fence panels. The no-dig approach eliminates the need for extensive digging and reduces the time required for fence installation.

Pros of No-Dig Fence Process:

1. Time and Labor Efficiency: No-dig fencing is notably quicker to install compared to the traditional method. The absence of extensive digging and concrete curing time allows for a faster and more straightforward installation process. This has specific advantages when installing gates. Instead of waiting 24 hours for conventional concrete to cure, once the post is driven in can support the weight of a singe or double gate immediately.

2. Minimal Disruption and Landscape Impact: The no-dig method minimizes disruption to the landscape. There's no need for heavy machinery or large holes, preserving the integrity of the surrounding area. This is particularly beneficial for those who want to install a fence without causing significant disturbance to existing gardens or hardscapes. Also, there is a lower risk of disturbing utility lines.

3. Adaptability to Various Soil Types: Pounding metal posts into the ground is suitable for a variety of soil types, including rocky or hard soils where digging may be challenging. This adaptability makes the no-dig method a versatile solution for different terrains. Very rock soil can present additional challenges so a hybrid method may be used were some posts are driven and some are dug and set with concrete.

Cons of No-Dig Fence Process:

1. Potential for Shifting: Since no-dig fences rely on the friction between the soil and the metal posts for stability, there is a potential for shifting over time, especially in loose or sandy soils. The potential for shifting is present in the dig and pour method as well, especially in sandy soils that have a high moisture content.

2. Load Capacity: No-dig fences may have limitations of load-bearing capacity. Since shear forces are correlated to post diameter, there is a limit to the size of the post that can be driven effectively. The upper boundaries are around a three inch diameter metal post. For project that have extreme load requirements a dig and pour approach may be more suitable.

Comparison with Traditional Digging and Pour (Concrete):

Traditional methods involve digging holes from 9" to 12", setting posts in concrete, and allowing it to cure. While this method provides excellent stability and resistance to shifting, it requires more time, effort, resources and can be disruptive to current landscaping.

Pros of Traditional Digging and Pour:

1. Stability and Durability: Concrete-set posts provide a stable and durable foundation, ensuring that the fence remains secure over time.

2. Suitability for Heavy Structures: Traditional methods are ideal for heavy or tall fences that require additional support to withstand external forces such as wind or pressure.

3. Industry standard: Dig and pour has been used for fencing for over 100 years and is widely accepted and the industry standard for professional fence instillation.

Cons of Traditional Digging and Concrete:

1. Extended Installation Time: The curing time for concrete significantly extends the installation timeline, making it a less attractive option for those seeking a quick fence installation. Temperature can also affect the concretes ability to achieve maximum strength. Too hot or cold can prevent concrete from curing properly.

2. Disruption to Landscape: The excavation process can cause significant disruption to the landscape, potentially damaging existing vegetation and hardscapes. The use of a 12" boring bit plus a mini-skid steer can leave disturbed dirt and disrupted landscape in its wake.

Conclusion:

Choosing between the no-dig fence process and the traditional method depends on specific needs and preferences. The no-dig approach offers speed, ease of installation, and minimal landscape disruption but may be less suitable for heavy-duty applications. Traditional digging and concrete provide unparalleled stability and durability but require more time. Ultimately, the decision should be based on factors such as soil conditions, fence height, and the desired installation timeline.
