What are helical piles?

Helical piles—also known as screw piles—are deep foundation elements made of steel shafts with helical (spiral-shaped) plates. They’re rotated into the ground like screws, reaching a stable soil layer to support structural loads for both permanent and temporary foundations.

When should helical piles be used?

Helical piles are ideal when soil conditions make traditional foundations unreliable. Common applications include:

• New residential or commercial construction
• Foundation repair or underpinning
• Retaining walls, boardwalks, and decks
• Projects in contaminated or restricted-access sites

How deep do helical piles go?

Most helical piles are installed between 10 to 25 feet below ground, but the actual depth depends on the soil conditions and load-bearing requirements of the project.

Are helical piles environmentally friendly?

Yes. Helical piles are removable, reusable, and cause minimal disturbance to the surrounding soil. This makes them a sustainable choice, especially for sensitive environments or areas with strict noise and vibration regulations.

Can helical piles be installed in any weather?

Absolutely. One of the biggest advantages of helical piles is their ability to be installed year-round, in virtually any weather, without relying on concrete curing times.

Do you perform load testing on helical piles?

Yes. At Rock Hard Excavating, we ensure every installation meets your project’s structural and settlement criteria through rigorous static load testing and torque monitoring.

What are site utility services?

Site utility services include installing, repairing, and maintaining essential infrastructure, such as water lines, sanitary sewer systems, stormwater management structures, fire hydrants, and more.

Yes. We assess and repair aging or inefficient systems to restore proper water flow, prevent damage, and bring them up to code. Our restoration services are efficient, cost-effective, and minimally disruptive.

What is a sewer disconnect service and why is it necessary?

Sewer disconnect services involve safely cutting off a property’s sewer connection to the municipal or septic system. This process ensures public health, environmental protection, and code compliance and is typically required before a demolition, major renovation, or new construction.

When do I need to disconnect my sewer line?

You’ll need a sewer disconnect when:

• Demolishing a structure
• Rebuilding or majorly renovating a property
• Upgrading sewer infrastructure before a new build
• Local jurisdictions often require disconnection and capping before issuing demolition permits.

Do you inspect the sewer lines before disconnecting?

Yes. We perform a full inspection using advanced sewer camera technology to assess the condition of your lines. This helps determine if existing pipes can be reused post-project, potentially saving you from unnecessary replacement costs.

Do you coordinate with local authorities?

We obtain necessary permits and coordinate with utility providers and municipalities to ensure a compliant disconnect process.

What is a sewer reconnect service?

A sewer reconnect involves restoring the connection between a property’s sewer system and the municipal sewer line after it has been previously disconnected. This is common during renovations, new builds, or after demolitions. It requires precise work to ensure the system flows properly and complies with all local codes.

When do I need a sewer reconnect?

You’ll need to reconnect if:

• You’re rebuilding on a property where the sewer was previously capped.
• Your renovation project requires the reactivation of an existing sewer system.
• You’re constructing a new home or commercial building and need a connection to the municipal line.

What’s involved in the sewer reconnect process?

Our reconnect process includes:

• Permit acquisition and municipal approvals.
• Sewer camera inspections to assess pipe conditions.
• Repairing or replacing damaged pipes if needed.
• Removing caps and reconnecting to the main line.
• Hydro jetting and pipe descaling to ensure clear flow.
• Final testing, inspection, backfilling, and property restoration.

What’s the difference between sewer repair and new sewer installation?

Sewer repair involves replacing or fixing damaged sections of an existing system, while new sewer installation is the process of laying down a brand-new system—typically for new residential or commercial construction.

When do I need a new sewer system installed?

You’ll need a new system if:

• You’re building a new home or commercial facility.
• The current sewer layout doesn’t meet updated building codes.
• The existing infrastructure is beyond repair or no longer efficient.

How do you ensure proper sewer installation?

We start by:

• Marking alignments for lateral and tap connections.
• Calculating accurate slope and elevation to ensure proper waste flow.
• Using approved materials and precise pipe placement techniques to avoid future issues like clogs, backups, or flooding.

What if I don’t have sewer layout plans for my property?

No problem. We use advanced sewer camera systems to map out your existing pipes and connections, ensuring minimal disruption and efficient planning—even when original blueprints are missing.

What is a sewer cap-off, and why is it necessary?

A sewer cap-off is the process of sealing a building’s lateral sewer line—the connection between your property and the main municipal line—before demolition. It prevents waste leakage, environmental contamination, and damage to the city’s sewer infrastructure.

How do you locate the sewer line before capping it?

We use advanced sewer video inspection tools to locate your lateral sewer line precisely. This ensures we choose the correct point of capping without damaging nearby pipes or utilities.

What materials are used to seal the sewer line?

It depends on the type of pipe:

• For plastic (PVC) pipes, we use specialized glues or caps.
• For cast iron or clay pipes, we use non-shrink cement grout for a durable, watertight seal.

What is pipe descaling and why is it necessary?

Pipe descaling is the process of removing rust, limescale, and other mineral deposits from the interior of your pipes. This buildup restricts water flow, leads to clogs, and can eventually cause cracks or corrosion—especially in cast iron or metal pipes.

How do I know if my pipes need descaling?

Common signs include:

• Slow drains or backups
• Unusual gurgling sounds from plumbing
• Foul odors coming from drains
• Recurring clogs, even after snaking

If you’re experiencing any of these, it might be time for a camera inspection and descaling.

What types of pipes benefit from descaling?

Descaling is especially effective for cast iron, galvanized steel, and older metal pipes, but it can also be used on other materials, depending on the buildup and pipe condition.

What methods do you use for pipe descaling?

We use three primary methods, depending on the pipe condition and severity of the scale:

• Pipe Scrubbing: A mechanical method using rotating abrasive tools to physically scrape buildup from inside the pipe.
• Chemical Descaling: Safe, professional-grade chemicals dissolve scale without damaging pipes.
• Hydro Jetting: High-pressure water blasts away thick deposits (used only on pipes that can withstand the pressure).

Is pipe descaling safe for my plumbing?

Yes. Before starting any descaling, we perform a sewer camera inspection to assess the condition of your pipes and choose the safest and most effective method.

How often should I have my pipes descaled?

We recommend descaling every 5 years to maintain healthy flow and prevent damage, especially in homes with older plumbing or hard water.

What is hydro jetting?

Hydro jetting is a high-pressure water cleaning method used to remove grease, scale, clogs, and debris from the inside walls of your pipes. It uses pressurized water up to 4,000 psi—no chemicals—to flush your plumbing system clean.

What types of blockages can hydro jetting remove?

Hydro jetting can tackle a wide range of problems, including:

• Grease buildup
• Hair clogs
• Food waste
• Scale and mineral deposits
• Small tree roots

It provides a more thorough cleaning than snaking or chemical solutions.

Is hydro jetting safe for all pipes?

No. Hydro jetting is not recommended for old or weakened pipes. That’s why our team begins every job with a sewer camera inspection—to assess pipe integrity before applying pressure.

How is hydro jetting different from snaking?

Snaking breaks through blockages but doesn’t clean pipe walls. Hydro jetting, on the other hand, scours the entire pipe interior, removing all buildup and preventing future clogs.

When should I consider hydro jetting?

Hydro jetting is ideal for:

• Recurring drain issues
• Foul odors from pipes
• Slow drainage despite snaking
• Routine pipe maintenance, especially in restaurants or commercial kitchens

Can hydro jetting be used in homes?

Yes. While hydro jetting is common in commercial properties, but it’s also highly effective for residential plumbing systems, especially older homes with metal pipes or chronic clogs.

How does sewer camera inspection work?

A professional plumber feeds the camera line into your pipes via a cleanout. As it moves through, live video footage displays the internal condition of the sewer line, allowing us to identify the exact problem location without unnecessary excavation.

Is it safe for my pipes?

Yes. Sewer camera inspection is a completely non-invasive method that is safe for all residential and commercial plumbing systems.

What problems can it detect?

The camera can detect:

• Tree root intrusions
• Pipe corrosion or wear
• Collapsed sections or cracks
• Grease or debris buildup
• Offset or bellied pipes

How long does the inspection take?

Most inspections take 30 to 60 minutes, depending on the length and complexity of the pipe system.

When should I get a sewer inspection?

If you’re experiencing frequent backups or slow drainage or are buying a new property, a video inspection is recommended to assess the condition of your pipes.
