Understanding Foundation Problems

What is the difference between sinking and settling?

  • Sinking refers to a rapid, uneven descent of a foundation into the ground, often due to a specific failure in the soil structure or improper foundation construction. It's characterized by significant and localized damage.
  • Settling is a more gradual process where the foundation adjusts uniformly over time due to the natural compaction of the soil beneath it. It's typically expected and occurs evenly across the foundation.

Why do foundations sink?

Foundations sink due to various factors, including water erosion, soil shrinkage, inadequate compaction of fill soil, and the presence of expansive clay soils that fluctuate with moisture levels. Poor construction practices and overloading can also contribute to sinking.

How do you know if your foundation is sinking?

Signs include visible cracks in the foundation or walls, uneven floors, doors, and windows that stick or won't close, and gaps between walls and the floor or ceiling. Exterior cracks may also appear in bricks or masonry.

What does a sinking foundation look like?

A sinking foundation may manifest as uneven settling of the house, with one or more portions of the building appearing lower than the rest. Cracks may develop at an angle, and there might be visible separation from doors and windows.

How do you tell the difference between settling and foundation problems?

While settling is a uniform process that happens slowly over time, foundation problems like sinking occur unevenly and more rapidly, often resulting in visible damage to the structure. Monitoring for rapid changes or uneven damage is key.

When should I worry about my foundation?

Concerns should arise if you observe rapid changes, such as sudden or large cracks in the foundation or walls, doors, and windows that no longer operate properly, and significant unevenness in the flooring.

When should I be worried about foundation settling?

While some settling is normal, excessive or uneven settling could indicate problems. Be alert to large or expanding cracks, especially those wider than 1/4 inch, and doors or windows becoming misaligned.

What causes foundation settling?

Settling can be caused by a natural compaction of the soil over time, especially if the soil was not adequately compacted during construction. Other factors include changes in soil moisture levels and the decomposition of organic materials in the soil.

Is it normal for concrete to sink?

Yes, it can be normal for concrete slabs, including foundations, to experience some sinking over time due to settling. However, excessive or rapid sinking is not normal and indicates underlying issues that need to be addressed.

Identifying Foundation Damage

How long does it take a foundation to sink?

The timeline for a foundation to sink varies significantly depending on the underlying causes, soil conditions, and construction quality. Some foundations may show signs of sinking within a few years of construction, while others may take decades. Rapid sinking over a few months to a year, especially, should raise immediate concern.

How much foundation settling is normal?

Minor settling is normal for most foundations and can occur over the first few years after construction. Generally, settling up to an inch is considered normal, but the uniformity of the settling is as important as the amount.

How do you know if your foundation is strong?

A strong foundation will show no signs of distress in the structure it supports. Doors and windows operate properly, there are no significant cracks in the foundation or walls, and floors are level. A professional inspection can provide a comprehensive assessment of foundation strength.

Are small cracks in foundation OK?

Small, hairline cracks are common as a house settles and are usually not a cause for alarm if they don't widen or grow. These can be due to minor settling or changes in moisture. Monitoring for changes in size or new cracks developing is important.

Which foundation cracks are bad?

Horizontal cracks, stair-step cracks in brick or block exteriors, and vertical cracks wider than ¼ inch are concerning. These types of cracks can indicate structural issues, such as foundation sinking or shifting, that may require professional assessment.

What cracks are bad in a house?

Cracks that are wide (over ¼ inch), growing, or accompanied by other signs of foundation distress (like doors that won't close) are bad. Horizontal cracks in basement walls, especially, are often signs of significant pressure on the foundation.

How many inches is bad foundation?

There isn't a specific "inch" measurement that universally indicates a bad foundation, as the concern is more about how and where the movement occurs. However, noticeable sinking or shifting of several inches, especially if it's uneven or rapid, signifies serious foundation issues.

How do you know if foundation is good or bad?

A good foundation will support a level, stable structure without significant cracks or movement over time. Signs of a bad foundation include large or expanding cracks, uneven floors, stuck doors/windows, and visible separation between walls and floors or ceilings. Regular inspections by professionals can help determine the condition of a foundation accurately.

Construction and Materials

Foundation Types and Depths

How deep is a foundation?

The depth of a foundation can vary widely depending on the type of structure, soil conditions, and local building codes. Shallow foundations typically range from 1 to 3 meters (3 to 10 feet) deep, whereas deep foundations can extend 20 meters (65 feet) or more into the ground.

What is the maximum depth of foundation?

The maximum depth of a foundation is dictated by the structural needs of the building, the soil characteristics, and the depth at which stable soil or bedrock is found. There's no set maximum depth, but deep foundations such as caissons or pilings can reach depths of over 60 meters (200 feet) in some cases.

What are the 4 types of deep foundation?

  1. Pile Foundations: Long, slender columns typically made of steel, concrete, or wood, driven into the ground to reach stable soil or rock.
  2. Drilled Shafts (Caissons): Large diameter concrete shafts drilled deep into the earth.
  3. Cofferdams: Temporary enclosures built within or across water bodies, pumped dry to expose the bottom surface, where the foundation is then constructed.
  4. Slurry Walls: Constructed by pouring concrete into a trench filled with a protective slurry mixture that supports the trench walls until it hardens.

How do you know if a foundation is shallow or deep?

A foundation is considered shallow if it is constructed near the surface of the last soil layer, typically less than the width of the foundation away. Deep foundations are used when shallow soils are not capable of supporting the structure's load, and the foundation must be extended to reach more stable soil or rock layers.

What is the difference between pile and deep foundation?

"Pile foundation" refers to a type of deep foundation that uses long, slender columns (piles) driven deep into the ground to support structures on weak soil. Deep foundations encompass a broader category, including pile foundations but also other types like drilled shafts and caissons, designed to transfer loads to deeper, more stable soil layers or rock.

How deep are deep foundations?

Deep foundations typically extend 20 meters (65 feet) or more below the surface, though the exact depth can vary greatly based on the project's structural requirements and the ground conditions. Some deep foundations have been known to go as deep as 60 meters (200 feet) or more.

What is a deep foundation called?

Deep foundations are generally categorized by their construction method and design, such as pile foundations, drilled shafts (or caissons), and slurry walls. Each type has specific applications and is chosen based on the soil conditions, load requirements, and environmental considerations of the construction project.


Material Considerations

What kind of cement to use for foundation repair?

For foundation repair, especially for filling cracks or making small patches, a high-strength, non-shrink grout or a structural-grade concrete mix is often recommended. These materials are designed to achieve strong adhesion and durability necessary for foundation repairs.

Can you put cement on top of cement?

Yes, you can put cement on top of existing cement, but proper surface preparation is crucial. The existing surface needs to be clean, structurally sound, and roughened for the new cement to adhere properly. Additionally, using a bonding agent can improve adhesion between the two layers.

Can I pour 1 inch of concrete over existing concrete?

Pouring 1 inch of concrete over existing concrete is technically possible but not always recommended due to potential adhesion issues and the risk of the new layer cracking. If proceeding, ensure the surface is properly prepared, and consider using a bonding adhesive. For best results, the new layer should ideally be at least 2 inches thick.

Can cement stick to old cement?

Cement can adhere to old cement if the surface is properly prepared and a bonding agent is used. The old cement surface must be clean, free of any loose materials or contaminants, and slightly moistened before applying the new cement.

Can you pour new concrete over old cracked concrete?

Pouring new concrete over old cracked concrete is possible, but it's essential to address the underlying cause of the cracks first. The existing concrete surface should be properly prepared by cleaning and applying a bonding agent. For large or structural repairs, consulting a professional is advisable to ensure the integrity of the new surface.

Financial and Legal Aspects

Financial and Legal Aspects: Cost and Budgeting

How much does it cost to fix a sinking foundation?

Costs can escalate significantly depending on the depth to stable soil and the size of the structure.

What is the cheapest way to level a concrete floor?

The cheapest way to level a concrete floor is often through self-leveling concrete overlays or compound applications for minor adjustments. These materials can be applied directly over an existing concrete floor to fill in low spots and create a level surface. This solution is suitable for small areas and where the height discrepancy is not severe. DIY options can reduce costs but may require careful preparation and execution for effective results.

Legal and Insurance Issues

Can you replace a foundation without lifting the house?

Replacing a foundation without lifting the house is extremely challenging and rarely feasible. Typically, the house must be lifted or supported in some manner to remove the old foundation and construct a new one. This process requires careful planning and execution by professionals to ensure the structure's integrity. In some cases, less invasive methods such as underpinning may be considered to reinforce and repair the existing foundation without complete replacement.

How fast can water damage concrete foundation?

The rate at which water can damage a concrete foundation varies based on several factors, including the type of soil, the quality of drainage around the foundation, and the presence of waterproofing measures. While concrete is inherently resistant to water, prolonged exposure to moisture can lead to erosion, cracking, and other forms of damage over time. In cases of severe flooding or poor drainage, significant damage can occur in a matter of months or even weeks.

Can water damage concrete foundation?

Yes, water can damage a concrete foundation over time. Although concrete is durable and water-resistant, continuous exposure to water, especially if acidic or contaminated, can erode the material and weaken the foundation. Poor drainage, flooding, and water accumulation around the foundation are common culprits. Water can also exacerbate existing cracks, leading to more significant structural issues.

Foundation Maintenance and Application

Maintenance Tips

How do you level a cracked foundation?

Leveling a cracked foundation typically involves underpinning methods, where piers or pilings are driven deep into the ground beneath the foundation until they reach stable soil or bedrock. These supports are then used to gradually lift the foundation back to its original level, closing cracks and stabilizing the structure.

How do you fix a sinking wall?

Fixing a sinking wall may require stabilizing the foundation first, as the wall's movement is often a symptom of underlying foundation issues. Techniques like underpinning can address the foundation problem, after which the wall can be straightened and reinforced. In some cases, hydraulic jacks can be used to lift the wall back into position before securing it.

How do you level sinking concrete?

Leveling sinking concrete, such as sidewalks or driveways, is often done through a process called slabjacking. This involves drilling holes into the concrete slab and pumping a slurry underneath to fill voids and raise the slab back to its original level.

How do you fix dips in walls?

Fixing dips in walls can involve applying a layer of plaster or joint compound to fill in the dipped areas. For more significant dips caused by structural issues, it may be necessary to address any underlying problems with the wall's support or foundation first.

How do you fix dips in concrete floor?

Dips in concrete floors can be corrected by filling the low areas with a self-leveling compound designed for concrete. This compound flows into the dips and hardens to create a level surface. For deeper dips, additional preparation and materials, such as a concrete patching compound, may be required before applying the self-leveling compound.

How do you fix dips in concrete slab?

Similar to fixing dips in concrete floors, fixing dips in a concrete slab involves cleaning the area, filling it with a concrete patching compound for deeper dips, and then applying a self-leveling compound to ensure a smooth, level surface across the slab.

How do you raise a sinking retaining wall?

Raising a sinking retaining wall may require excavation around the affected area to relieve pressure and assess the underlying issue. Solutions can include underpinning the wall with piers or anchors to stabilize and lift it, or rebuilding portions of the wall if the damage is extensive. Proper drainage solutions should also be implemented to prevent future sinking.


Application Techniques

  1. How many pumps of foundation should you use?

    • The number of pumps of foundation you should use depends on the coverage you desire and the consistency of the product. Generally, start with one pump and gradually add more if needed, focusing on building coverage in thin layers for a natural look.
  2. How to make a flawless foundation?

    • To achieve a flawless foundation application, start with clean, moisturized skin. Use a primer to smooth the skin's texture and help the foundation last longer. Apply foundation using a damp makeup sponge, brush, or fingers, blending it evenly over the face and neck. Use concealer to spot-correct any imperfections, and set the foundation with a translucent powder for a long-lasting, flawless finish.
  3. What is the best way to apply foundation?

    • The best way to apply foundation depends on personal preference and the desired finish. Some popular methods include using a makeup sponge for a seamless, natural look, a foundation brush for precise application and buildable coverage, or fingers for quick and easy blending. Experiment with different techniques to find what works best for your skin type and desired makeup look.
  4. What if my foundation is too thick?

    • If your foundation is too thick, you can try mixing it with a lightweight moisturizer or primer to thin out the consistency. Alternatively, you can use a damp makeup sponge to apply the foundation, which can help sheer out the product for a lighter coverage. Remember to start with a small amount and gradually build up coverage as needed.

Structural Integrity and Longevity

Determining the strongest type of foundation depends on various factors such as soil type, building structure, and local building codes. However, some common types of foundations known for their strength include:

  1. Reinforced Concrete Strip Foundations: These are continuous footings that support load-bearing walls. They distribute the building's weight evenly, providing excellent strength.

  2. Reinforced Concrete Slab Foundations: Ideal for areas with expansive soils, these foundations consist of a single layer of concrete poured directly onto the ground. They offer robust support and are resistant to ground movement.

  3. Pile Foundations: Used in areas with weak soil conditions, pile foundations transfer the building's load to deeper, more stable soil layers or bedrock. They're particularly strong for tall or heavy structures.

The strength of a foundation is determined by its design, materials, and construction quality rather than a specific type. It's essential to consult with a structural engineer or a building professional to assess which foundation type is suitable for your specific project.

As for the size of cracks acceptable in a foundation, it largely depends on the severity and location of the crack. In general, hairline cracks are common and may not indicate a significant structural issue. However, cracks wider than 1/4 inch or those accompanied by other signs of foundation damage, such as uneven floors or doors sticking, should be inspected by a professional.

The weight a foundation can hold also varies based on factors like soil bearing capacity and the design of the foundation itself. Engineers calculate load-bearing capacities during the design phase to ensure the foundation can support the intended structure's weight safely.

The terms "footing" and "foundation" are often used interchangeably, but there's a distinction between them. A footing is the part of the foundation that sits below ground level and spreads the building's load over a wider area to prevent settling. The foundation, on the other hand, refers to the entire structure that supports the building above ground level, including the footing and any walls or slabs.

In terms of longevity, properly constructed and maintained concrete foundations tend to last the longest. However, factors such as soil conditions, climate, and maintenance practices can influence a foundation's lifespan.

Among the various types of building foundations, a well-designed and constructed reinforced concrete foundation is typically considered the longest-lasting for residential structures.

When a foundation sinks, it can lead to serious structural problems such as uneven floors, cracks in walls, and misaligned doors and windows. If left unaddressed, foundation sinking can compromise the stability and safety of the entire building.

Fortunately, many issues with foundations can be repaired. Solutions may include underpinning, which involves strengthening the foundation by extending it deeper into the ground, or mudjacking, which involves injecting a stabilizing material beneath the foundation to lift and level it. However, the appropriate repair method depends on the specific cause and extent of the foundation damage, so it's essential to consult with a qualified foundation repair specialist.
