Foundation Repair Settlement in Columbia MO

  1. 1. Foundation Problems In Columbia, MissouriOur particular foundation problems inand near Columbia, Missouri are due tothe types of soils we have. While theglaciers long ago brought us mineralwealth and our flat prairie land, theyalso left sizeable clay deposits. It is theclay that is one source of our problems,as this can expand and contract -causing extreme stress on any buildingfoundation or basements.Another interesting scenario is the coal that has been mined (or not) below the surface. You cansee many of the old mining pits that several housing developments have built close to and ontop of. While these used to be on the city limits, expansion has taken over many of these areas,especially as Nature has tended to reclaim their rocky surfaces with new growth over the years.Finally, formerly undisturbed land that had been near creeks and run-off areas has beendeveloped extensively as the housing demand continued to grow. While early settlers couldafford to pitch their cabin on high, well-drained soil, our newer houses have been placed nearor right on top of natural drainage lines. And even though our new technologies and variousmeans of dealing with run-off have improved on historical problem areas, these moisture-enabled areas can and do affect the security of our home foundations.This series of PDFs are designed to give you more information about cracks, settlement, bowedwalls, and shifting slabs.

  2. 2. What does that crack in the side ofyour home, your concrete foundationor basement wall mean?Is your home slowly disintegrating asyou live in it? Is there some majorcatastrophe about to happen? Arethose cracks related to the moisture inyour basement or under your home?Foundation settlement and movementtypically in Missouri is caused bybuilding on expansive clay,improperly compacted fill soils, orimproper maintenance aroundfoundations.Almost like oil and vinegar, it isnt a good mix when water meets clay. Clay and water attracteach other instead of repelling. This is the beginning of the story that your cracks are trying totell you.Soil Suction Moisture can move from outside to under your foundation through a property of soils known as suction. Soil suction is similar to placing just a corner of a dry, compressed sponge in contact with a puddle of water. In a short time, the sponge has drawn water throughout itself and gotten larger. While a water source is present, the sponge will continue to absorb water until it is completely filled. Like a sponge on a plate - if you stop adding water, the sponge moves the water around inside so its all uniformly damp, but still can take more.This is how water can move horizontally and vertically through the soils under yourfoundation. As clayey soils draw water to themselves, they too grow in volume (swell orheave) causing your foundation to move. The pressures are intense, since the clay has nowhereto expand. Drying outside your foundation reverses the process. The moist soils will losevolume (shrink) as soil moisture moves out from under your foundation causing the foundationto settle. You may have seen this out in your yard, where the soil opens up cracks in the surfaceduring dry periods. Our clay soil is expanding and contracting every day and month out of theyear. Your foundation is taking this stress.
  3. 3. Shrinking and swelling soil motions can lead to damaging your foundation and structure.Uniform changes in soil moisture are less damaging to your structure than localized changes.We know the soil varies from location to location. Soil also changes with construction, as youmay have various soils and soil types added to fill a low spot or restore sod when a higher areais removed.The rest of this PDF series will tell you more about these causes and their solutions. For now,do an inspection of your home and note the cracks present. Measure their length and anynoticeable gaps. This inspection should then be done after the next rain and regularly after that.This is how you can find the stories your cracks are trying to tell you.Related Sites From Columbia Foundation Repair Site:Foundation Repair Jefferson City, MOFoundation Repair Fulton, MO Foundation SettlementCrawl Space Repair Columbia, MO SettlementCrawl Space Repair Jefferson City, MO Bowed Or Leaning Walls Foundation CracksAlso of Interest: Sinking Slab Foundation Problem CausesFrom Gibbons Basement Inc.: Soil Effects Moisture EffectsFoundation Repair Exterior LeaksCauses Of Foundation Settlement Other Drainage IssueFoundation Settlement SolutionsBowed or Leaning Basement Walls Foundation Repair SolutionsResistance Piers Solutions for Foundation SettlementHelical Piers Solutions for Sinking SlabsNew Construction Foundation Piers Solutions for Bowed Walls Contact Us Provided as a public service by Gibbons Basement, Inc.
