Sewer Line Repair & Replacement

Various elements can lead to damage within your sewer line, as outlined below. If you suspect a compromised line, addressing the problem promptly is crucial. Septic Check is proficiently equipped to identify, assess, and rectify damages within these sewer lines, ensuring a swift and effective resolution

Contributers to line damage:

1. Tree Roots:

  • Tree and plant roots are often drawn to sewer lines due to the water, nutrients, and oxygen they contain.

  • They can infiltrate the pipes through joints or cracks, and, over time, can block the pipe or cause it to break.

2. Aging and Corrosion:

  • Over time, sewer pipes, especially those made of iron or steel, can corrode and deteriorate, leading to leaks, breaks, or collapses.

  • Even PVC pipes, though more resistant to corrosion, can become brittle and crack over time.

3. Ground Movement:

  • Shifting soil or settling ground can lead to pipe misalignments, fractures, or collapses.

  • Earthquakes, landslides, or other ground movements can also damage sewer lines.

4. Blockages:

  • Accumulation of grease, hair, and other debris can cause blockages in sewer lines, leading to backups and possible damage.

  • Foreign objects flushed down toilets can also block pipes.

5. Temperature Changes:

  • In colder climates, sewer lines can freeze and then burst as the contents expand.

  • Extreme temperature fluctuations can also cause the ground to contract and expand, potentially damaging the pipes.

6. Improper Installation:

  • Poorly installed sewer lines are more susceptible to problems such as leaks, breaks, and blockages.

  • Incorrect slopes, poor pipe connections, or use of improper materials can lead to future issues.

7. Chemical Damage:

  • The continual disposal of harsh chemicals and cleaners can degrade the interior of sewer pipes over time, leading to damage.

8. Traffic and Construction Activity:

  • Heavy traffic or construction activity can exert pressure on the ground, potentially damaging buried sewer lines.

  • Direct impact from construction equipment can also cause breaks or collapses.

9. Clogs from Non-Flushable Items:

  • Flushing non-biodegradable items like wipes, diapers, sanitary products, or plastic can lead to severe clogs and possibly damage the sewer line.

10. Sagging or Bellied Lines:

  • Over time, sections of the sewer line can sag due to ground conditions, creating a "belly" or low spot where waste can accumulate and block the flow, leading to damage.

Drainfield Repair

All conventional septic systems have a finite life. Even properly used, drainfield rock eventually becomes plugged with the by-products of treating sewage. Septic systems that are used properly will still eventually fail. Replacement costs run from $7,200 to $20,000 or more in some areas.

Why systems fail:

As systems age, a clogging mat forms where the rock and soil meet. This biomat is comprised of dead bacteria, fine solids, and live soil bacteria. It performs a vital function by holding water in the rock long enough to prevent saturation of soil below the rock.
Over time this clogging mat gets too thick, however, and causes water to pond in the rock. Air is displaced by liquid and anaerobic conditions begin the decline of the soil treatment system.
Even if properly designed and constructed, conventional septic systems eventually need replacement or rehabilitation. Homeowners using them within design limits can expect drainfield or mound life of 7-25 years.
We offer system saving recovery solutions that can provide an immediate fix to your septic system and avoid replacement cost. Our service areas in Minnesota include Milaca, Princeton, Zimmerman, Isle, Onamia, Aitkin, Wahkon, Garrison, and surrounding areas. Contact us for a free site visit and estimate.

Terralift Drainfield Rejuvenation

The Terralift drainfeild repair provides new life for your problem drainfield or mound in one day without excavating your lawn. The Terralift process injects high pressure blasts of air into the ground to fracture soil and re-establish percolation. In addition, it stirs up excess biomat which is then digested. It provides an immediate fix to ponded and surfacing drainfields.
