It is a popular dream of the common American to own a home. It seems like the culmination of all the high school and college efforts, and a little certificate on its own of how well you have done in your career. Whether you build yours or you bought yours, you financially have a stable roof over your head –a personalized roof this time. Good for you!
How about the foundation of your home? The type of foundation on which your house was constructed is of immense significance as it actively indulges in the durability and structural sustainability of the building. You could have seen houses which don’t have a basement, right? They don’t have a crawl space. Such buildings are simply built on a concrete slab. The factors motivating such construction methods is not farfetched. It could be because the site location has a high water table. Another reason that could inspire this kind of slab foundation is the building being constructed on a bedrock.
Getting a slab foundation done involves digging say a foot or thereabout into the ground in the proposed siting of the house. After going in by that foot as stipulated, concrete is then poured in the dug ditch and then reinforcement is realized by means of steel bars. After this building of the house starts proper! The composition of the soil of the location is another gigantic factor to draft into calculation when deciding on going with slab foundation or not. This is why a lot of buildings in Texas and other southern US states readily go with slab foundation.
Of course, slab foundations have their immense advantages. One pretty advocate of slab foundations is that they comparatively take less to construct financially. Getting a slab foundation done is unlikely to burn a big hole into your pocket. We have seen cases where as much as $10,000 was saved in building cost by adopting the choice of slab foundation. In addition to this, slab foundation heavily help in preventing flooding. What more, it takes lesser time for your slab foundation to dry. So you are forgiven if you completely think slab foundation is good business and you can readily jump into it. Of course it has its good sides, yet slab foundations have their dark sides. Before you rush to take slab foundations, exercise patience let us go through some reasons why you should calmly have a second thought.
Slab foundations are so commonly plagued with shifting
This is one of the most popular woes of slab foundations. Shifting precisely uneven shifting. Slab-on-grade foundation are so miserably afflicted with shifting and this is almost deserved. For one thing slab foundations are not really deep. So when there is the occurrence of soil expansion close to the surface, they are readily affected. Therefore the foundation is molested with undistributed pressure from expansion and contraction of the slab foundation. The end product of this could be settling. In other cases, it could be cracking or even worse sinking!
Slab foundations are regular victims of inconsistent soil moisture
Although during the construction of slab foundations, we have good level of moisture in the soil on the site. This gets constructors smiling only for a wretched frown to sneak in when they realize that such even level of moisture can go AWOL anytime and be altered. In fact slab foundations have a way of disrupting the consistency of soil moisture. The slab may bow from the wet soil near the foundation drying up. This is facilitated hastily by the faster of shrinking (and drying) of the soil at the edges of the foundation as compared against the slower drying foundation center.
Tree roots readily break into the slab
Such moisture in the soil under the foundation of the slab is an open invitation to tree roots to come and sure they honor the invitation. Tree roots are notorious for their gravitation and how their roots search for water. Now when those roots detect moisture (or water) under or around your foundation, they will come calling. The roots will break into the slab eventually cracking it more with expansion and consequent dangers to your foundation.
So there you are. These thoughts should guide you when choosing your type of foundation. Slab or not!
