  • Love these guys. They are professional, punctual, and saved me $1,000's explaining exactly what my foundation problem was and what I needed. Other companies were trying to sell me on the bells and whistles pushing services I didn't really need. These guys were transparent and the pricing for the job came out about $500 less then the other quotes.

  • Does Foundation Movement Affect Saint Augustine, Florida?

    Unfortunately, foundation movement and the resulting damages are widespread problems in Eastern Florida and throughout the state. Property owners in Saint Augustine, Jacksonville Beach, Atlantic Beach, Gainesville, Orlando, Orange Park, Ponte Vedra, and many other cities in the surrounding areas are regularly faced with foundation problems and sometimes astronomically high repairs.

  • What Causes Foundation Problems In Saint Augustine, Florida?

    There are a few factors related to the geology and the climate in Saint Augustine that make it less than ideal for foundation stability and longevity. We’ll discuss the most common underlying causes of damages below.

    Poorly-Drained, Sandy Soil

    Florida’s Atlantic Coast is well-known for its abundance of beautiful beaches, but the gradual deterioration of seashells, oceanic rock, and other organic materials that created the beaches also contributes to very sandy soil throughout Eastern Florida.

    The most abundant dirt in the area is called Myakka soil, which has a high ratio of sand to other soil particles. Sandy soil typically drains rapidly, but the total lack of elevation above sea level and minimal topographical relief leave the area poorly drained. Poorly-drained, sandy soil is detrimental to foundations for a few reasons.

    First, Saint Augustine’s soil is prone to underground erosion because the sand particles are so large and loosely packed. Runoff moving through the ground often pulls the soil with it, contributing to instability under your home.

    Over time, the soil can sink at varying rates depending on how rainwater drains through it, leaving sections of your foundation without level support. The process of uneven movement is called differential settling, and it can easily cause structural damage to your property.

    Much of the area is not only at or slightly above sea level but is also poorly drained, meaning the groundwater is located very near to the surface. When rain falls on the city and soaks into the ground, it has minimal space to drain before getting backed up to the surface.

    The frequently saturated soil can leave your foundation exposed to moisture for long periods, allowing it to wick through cracks or pores in your concrete slab. The result is prevalent water intrusion and moisture accumulation under your first floor, which can lead to damaging and hazardous mold growth, rotting of construction material, and decreased indoor air quality.

    Concentrated Rainfall and Flooding

    The risk of underground erosion of Saint Augustine’s sandy soil and elevated groundwater is made more severe by rainfall. While the city receives an average amount of rain, the precipitation is concentrated from June to October during hurricane season, when hurricanes and tropical storms bring more than double the monthly rainfall the rest of the year.

    The heavy rainfall during those months increases the rate of underground erosion and the resulting differential settling beneath your house. The poor drainage in the area not only exposes your concrete foundation to moisture for long periods during these months, but it also contributes to multiple types of flooding in St. Augustine.

    The majority of the city is situated in a flood plain, with most areas being prone to tidal flooding from the ocean and rivers. Flash floods are also common because of the shallow groundwater and slowly draining soil.

    Flooding contributes to underground erosion as an abundance of water drains through the soil. It also increases the likelihood of water intrusion and moisture accumulation under your home.

    Acidic Soil

    Myakka soil is known to be acidic, as are most of the other soil types in the region. This is primarily because of the deterioration of organic materials in the ground, like seashells. Acidic soil is detrimental to foundations, as it can eat away at the concrete over time, gradually weakening it.

    The process of foundation corrosion occurs over many years, but eventually, you could be left with a structurally compromised concrete slab.

    Limestone Bedrock

    Lastly, Florida’s bedrock is mostly limestone and dolomite, two minerals that can be supportive in the right conditions. However, they also dissolve in the presence of water, meaning that groundwater and draining runoff will erode them over time and leave subterranean caverns and channels behind.

    These voids are the reason that sinkholes are such a widespread issue in Florida. The loose, sandy soil above these caverns and waterways can eventually collapse, creating instability in the ground above. Differential settling is a significant risk above these areas of eroded bedrock. If the voids are large enough, sinkholes can form and cause massive damage to your foundation and your home, often necessitating structural repair.

  • What Are The Signs of Basement Foundation Damage In Saint Augustine, Florida?

    The symptoms of foundation damage that you notice in your home can vary depending on the underlying cause and how extensive the problem is. Below, we’ll describe the more typical signs of a foundation issue in Saint Augustine and the likely culprit.

    Foundation Cracks

    Cracks form in most concrete foundations, but they don’t always signify structural problems or significant damage. Identifying foundation cracks in Saint Augustine can be challenging; physical damages are easiest to see in crawlspaces and basements, but most homes in the area are built on slabs that are hidden from view. However, the location and direction of the fissure can help determine the severity.

    Hairline Cracks

    Hairline cracks that are thinner than ⅛” develop on nearly all foundations, and you may notice them while replacing flooring on your lower level. These cracks are generally harmless, as they result from the natural settling of the concrete after new construction. The risk of water intrusion and moisture build-up in Saint Augustine means you should consider having them sealed, but no stabilization is typically necessary.

    Wide or Uneven Cracks

    If you uncover cracks on your slab that are more than ⅛” wide or that have two sides that aren’t level with one another, your foundation is likely suffering from differential settling. These cracks are prevalent in St. Augustine because the sandy soil, concentrated rainfall, and karst topography all contribute to the risk of uneven settling under your home.

    gaps in the wall

    These gaps need to be stabilized by a concrete repair specialist as quickly as possible to limit the structural damage to your home.

    Cracks Near the Corners of Your Foundation

    If you inspect the visible area of your home’s foundation outside, you may notice cracks that begin on one side of your foundation and move around the corner to the perpendicular face.

    Fissures that follow this pattern are typically a result of differential settling as well, and they suggest that the corner of your property, which is the most prone to uneven settling, is sinking into the ground more quickly than the rest of your home.

    These cracks should be addressed by a concrete repair company immediately, as they can result in massive damage to your structure.

    Vertical Slab Cracks

    The last type of crack you’re likely to see on your concrete slab is one traveling in a vertical direction on the outside of your foundation. These are typically not severe and only indicate that normal settling has occurred. The best option is to have them sealed by a foundation repair contractor to prevent water and moisture issues.

    Crumbling Foundation

    The acidic soil in Eastern Florida can deteriorate concrete over time, so you may notice crumbling sections of foundation or large gouges underground or near the earth’s surface. Some homeowners find that they can pull pieces of concrete off of the foundation with just finger strength, which is a clear indication that the concrete is weakened.

    Poor Indoor Air Quality

    Lastly, water and moisture seeping up through your slab can accumulate between your foundation and first floor, increasing the humidity in the small space and your living area above.

    Humid air often makes temperatures feel more extreme, so unusually hot or moist air in your home can indicate that you have a problem with water or water vapor getting through your concrete. You and your family members may try to combat the discomfort using your cooling system, so above-average utility bills can also indicate a water issue.

    Moisture promotes mold growth and also naturally attracts insects. As such, you may have moisture build-up under your first floor if you notice musty odors, visible mold growth, or frequent pest infestations in your home.

  • How to Find Signs of Foundation Damage In Saint Augustine, Florida?

    Foundation damage can be challenging to identify in Saint Augustine because most foundations are slabs that aren’t easily accessible for inspection. Problems also tend to develop slowly and go unnoticed. We recommend carrying out a full property inspection every three or four months to look specifically for budding issues. We’ll detail a comprehensive foundation inspection below.

    Inspect the Concrete Under Your Home

    You can begin your examination by inspecting the concrete under your home, as most problems will originate there. Checking the surface of your slab will be challenging unless you are replacing or removing your flooring for some reason. If you are, check the area thoroughly for fissures, and report any uneven or wide slab cracks to a concrete repair expert.

    Otherwise, your inspection will need to take place outside. Look for cracks on the strip of concrete under your home and report them to a concrete repair specialist for sealing.

    You should give special attention to your structure’s corners, as differential settling will most often affect these areas. You should also check for signs of crumbling or gouges in the foundation, which can indicate problems with corrosion from the acidic soil.

    Inspect the Outside of Your Home

    Once you’re done examining the concrete beneath your house, you can look at the rest of your property for signs of damage or drainage issues. Look for sagging or wavy roofing, crumbling chimneys, and cracks in your stucco, brick, or stone siding. These can all signify differential settling in the concrete below.

    Divots in your lawn, damaged retaining walls or seawalls, and puddling on your property following rainfall or flooding suggest that you have drainage or settling issues that could have an impact on your foundation over time.

    Inspect the Inside Your Home

    Finally, finish your inspection inside, where you’ll look for signs of differential settling and moisture or water issues. Symptoms include cracking sheetrock, nails pushing through the drywall, and other damages that require wall repair.

    You may also see countertops or cabinets separating from the walls in your kitchen or bathrooms, doors or windows becoming challenging to open or close, and buckling or sloping flooring as a result of differential settling.

    Pay attention for moldy odors, high utility bills, and uncomfortably hot temperatures in your living space. These symptoms can signify moisture accumulation between your slab and your first floor.

  • Cost of Basement Foundation Repair In Saint Augustine, Florida?

    Foundation repair services cost an average of around $5,500 in Saint Augustine, but the total can be as low as $250 or above $100,000. It’s challenging to estimate repair costs in most cases, but we’ll offer some general pricing for common home improvement projects in Eastern Florida below.

    Cost to Seal Foundation Cracks

    Foundation cracks that aren’t indicative of structural damage can often just be sealed to keep water and moisture out. This is the most straightforward crack repair, and most general contractors in the area charge between $250 and $750.

    Cost to Fix Sinking Foundation

    The best solution for problems with differential settling is underpinning. Foundation repair specialists install push piers under your foundation to support the concrete in areas where the soil has eroded or sunk into the ground. Helical piers are the typical piling used in Saint Augustine, and they cost around $3,000 each.

    Most homeowners in the area pay between $10,000 and $20,000 for this type of concrete leveling. Your price will depend on the number of helical piles needed and the size of the affected area.

    Foundation leveling can also be done using mudjacking, which is the use of a cementitious solution under your slab to raise it up to its original position. This is a less permanent solution and rarely comes with a warranty, but it can be very useful for minor issues or for pool decks and patios.

    Cost to Fix Water Intrusion or Moisture Build-Up

    A waterproofing system may be required if you have frequent or severe problems with water intrusion or moisture build-up in your home. The system typically includes an exterior drainage system, foundation encapsulation, gutters, leaders, and gutter extensions, among other methods for limiting water near your concrete slab.

    The average price for one of these foundation systems is around $5,500, but your total can range from $2,500 up to $10,000 depending on the size of your home, the severity of the problem, and how straightforward excavation is outside.

    Cost of Sinkhole Repair

    Sinkhole remediation is a somewhat complicated and time-consuming process, so it is typically the most expensive repair solution. It’s best to choose a foundation repair company with years of experience and positive testimonials, even if their pricing is more expensive than other options.

    Some homeowners pay as little as a few thousand dollars, while larger repair jobs can reach over $100,000. The average price is around $12,000, but your total can vary based on the size of the sinkhole, the ease of access, and the damages they caused to your home that also require repair.
