How Expansive Clay Soil in Denver Affects Plumbing

Key takeaways:

• Denver's expansive clay soil can expand up to 20% when wet, exerting forces strong enough to damage foundations and underground plumbing systems.
  
  
• Regular plumbing inspections, drain cleaning, and water management are essential to prevent costly repairs caused by soil movement in Denver homes.
  
  

Most of Denver is composed of alkaline clay soils, and these soils can be bad news for homeowners. Clay soils can expand and shrink over time, creating movement and issues that often lead to costly home repairs. That's why it's important to understand what the potential issues are and how to prevent them.

Regular maintenance and professional help can keep your home safe. Regular drain cleaning and plumbing inspections help identify early warning signs of soil-related issues before they escalate into costly repairs. Roto-Rooter’s experienced technicians understand the unique demands of Denver's soil conditions and provide specialized water damage restoration services. Professional plumbing inspections can identify early warning signs of soil-related damage; our team is available 24/7, 365 days a year at 800-768-6911.

What is expansive clay soil, and why is it a Denver problem?

Let's start with facts: Clay soils can expand by 20% when wet, creating forces strong enough to damage foundations and plumbing. When the soil shifts and moves, it can stress building foundations and misalign underground pipes.

The movement stems from the bentonite minerals contained in clay soil, a common feature throughout Denver's geological landscape. During wet seasons or after plumbing leaks, soil absorbs water and expands significantly: up to several inches in every direction. This expansion can exert thousands of pounds of pressure against foundations and buried pipes, leading to stress fractures, sewer line damage, and pathways for water to enter basements. When dry conditions return, the soil shrinks away, potentially leaving gaps that compromise structural stability and underground plumbing systems.

While these challenges are common, professional water damage restoration services and regular plumbing maintenance can help repair and protect homes from expansive soil damage.

Warning signs of expansive clay soil damage in Denver homes

Your Denver home may be showing signs of expansive soil damage right now. Here's what to watch for.

Inside your home:

• Sticking doors or windows that won't close properly: This can indicate shifting foundations, which may lead to further structural issues if not addressed promptly.
  
  
• Uneven or sloping floors across rooms: This may suggest significant foundation movement, affecting the stability of your home and requiring immediate attention.
  
  
• New cracks in the walls, especially near door frames: These cracks can signal stress on the structure, often exacerbated by expansive soil, and should be monitored closely.
  
  
• Gaps appearing between the walls and ceiling: Such gaps can indicate foundation settling, which may lead to more severe structural problems if left unchecked.
  
  
• Molding or trim pulling away from the walls: This can be a sign of shifting walls due to foundation issues, suggesting the need for a professional evaluation.
  
  

Around your foundation:

• Water pooling near the foundation walls: This can lead to erosion and increased pressure on the foundation, heightening the risk of cracks and water intrusion.
• Visible cracks in the foundation, particularly if wider at the top or bottom: Wider cracks can indicate serious structural issues, requiring immediate professional assessment to prevent further damage.
• Soil pulling away from the foundation edges: This can create voids that compromise the foundation's stability, making it essential to address drainage issues right away.
• Tilting chimneys or posts: A tilting chimney may indicate significant foundation movement, which can lead to expensive repairs if not corrected quickly.
  
• Bulging walls in the basement or crawl space: Bulging walls can signal severe foundation issues, often requiring urgent intervention to prevent collapse.
  
  

Plumbing warning signs:

• Drains backing up regularly: Frequent backups may indicate blockages or damage in the plumbing system, necessitating professional drain cleaning to prevent further issues.
  
  
• Unexplained drops in water pressure: This could be a sign of leaks or issues within the plumbing system, making water heater repair essential for maintaining efficiency.
  
  
• Damp spots appearing on the walls or floors: These spots can indicate leaks or moisture intrusion, which may lead to mold growth and structural damage if not addressed.
  
  
• Sewer smells from drains: Unpleasant odors can suggest sewer line issues, potentially requiring sewer line repair to prevent health hazards.
  
  
• Gurgling sounds in pipes when running water: Gurgling can mean there is air trapped in the plumbing system, which is often a sign of blockages or venting issues that need professional attention.

How to protect your home plumbing and foundations from Denver's expansive clay soil

Protecting your home's plumbing and foundation is straightforward with the right approach.

• Start by managing water around your foundation.
  
  
• Maintain drainage systems. A well-maintained drainage system keeps soil moisture balanced through Colorado's dramatic weather shifts. Proper drainage becomes extra important during spring snowmelt and summer thunderstorms.
  
  
• Grade the yard to slope away from your home.
  
  
• Direct downspouts at least six feet from the foundation.
  
  
• Lightly water around the foundation during dry winters to prevent extreme soil shrinkage.
  
  
• Schedule professional drain cleaning each spring and check your water heater in the fall.
  
  
• Conduct monthly foundation checks for cracks or shifting soil, especially after weather changes.
  
  
• Install a water softener to protect pipes from mineral buildup.
  
  
• In the kitchen, maintain a properly functioning garbage disposal. This helps prevent drain clogs that could lead to water backing up near your foundation.
  
  
• Check outdoor spigots and visible pipes monthly for leaks.
  
  
• Utilize professional water damage restoration and sewer line repair services for soil-related issues.
