Crawl Space Foundation

Different Foundation Techniques and There Benefits For Housing
There are three basic foundation types and they are basement, crawl space and slab-on-grade. The different foundation techniques and there benefits will be examined here. There has been quite an upsurge in interest recently about the design as well as the construction methods of house foundations and the main reason for this has been connected to the conservation of energy, although people are becoming ever more aware of radon gas seeping into their homes.
House owners are now looking very carefully at the design of house foundations with a view to cutting costs and making a house more comfortable to live in. Many years ago, the down payment followed by the monthly payments for the mortgage installments were the most important considerations. Today however, with high energy bills and upkeep costs, the focus is beginning to shift. Homeowners not only want to be able to buy a house, they want to be able to live in it too.
The construction method used for the first foundation type, the full basement, is to dig the hole for the basement, erect forms the thickness required for the walls then pour liquid concrete into the forms. Once the concrete has dried the forms are removed and a solid insulated wall remains. This type of construction is utilized in areas where frost occurs in the ground. Using the proper insulation, a basement room can be conditioned to the extent that it can be warm enough for family activities on even the coldest days.
Another method used for basement construction utilizes concrete blocks for the walls. These blocks are usually hollow and reinforcing rods may be passed through the holes. Quite often, the holes are filled with liquid concrete. Insulating measures to guard against water seepage, radon and termite infestations should be considered.
The next foundation type is the crawl space. This is used on sloping ground or where the bedrock is fairly close to the surface making a basement foundation very expensive. The crawl space foundation is constructed by building a low cinder block wall the shape of the house on a concrete plinth, just wider than the wall, which is then faced with bricks. There is no slab to lay as the floor joists are attached to the wall and the interior of the wall is left as soil. The walls are built on top of the flooring timbers.
This type of construction makes it easy to run plumbing and electrical wiring under the house. It also simplifies maintenance and the relocation of these services if required, thereby cutting costs. The space under the house may be used for storage if certain steps are taken to keep out the elements and to protect the stored articles from termites.
The last foundation type is the slab-on-grade which is often utilized where the depth of a water table is less than 8 feet of the ground surface. The major components of this type are the slab itself with grade beams or footings around the edges making the slab thicker at its perimeter. The slab and the supporting walls are poured from liquid concrete and the floor is designed to be strong enough to support varied loads when poured onto compacted or bare soil without reinforcing.
The type of foundation chosen will depend on various factors, such as cost, aesthetics and the expectations of the buyer who will in many cases be interested in the different foundation techniques and there benefits.

Is 130,000 too much to pay for a double wide on a crawl space foundation?
We are in upstate NY and cannot find a house to buy in our price range…~150k. There has been an updated 1989 double-wide listed, 1600 sq. ft on a foundation (crawl space). It has newer appliances, roof… needs new windows. It has ceramic tiled bathrooms, whirlpool tub, nice extras there. Has no garage or outbuildings… just a slate patio and deck that needs a little work.
On one hand, to get a home that needs little work at a price we can afford is appealing, but I have a feeling the asking price is too high. How do I get a good price on this type of home without offending the seller? I am not looking for a super deal here… just a fair, honest price.
The home is on a 1/2 acre lot on a country road. Behind the lot is an open field.
Oh, I should add that I found a website that lists recent home sales. The website advised that this home sold in October 2006 for 61,000. (presumably before the updates and new roof were done.) They are asking 148k, but how much would be a more reasonable offer?

Is my crawl space foundation in trouble?
I live in middle Tennessee. My home was built a bit over three years ago. I have a crawl space. The floor of the space is covered with gravel and there is a black tarp on top of the gravel (I guess it is the vapor barrier). I have not really had a problem before, but it has rained a BUNCH over the last couple of days.
Today, we noticed brush debris in my yard and my neighbor’s, and there was mud about two feet into my garage where water had actually flowed into it at one point. I was compelled to look under my crawl space and noticed that on the perimeter concrete walls there is dampness about two inches off the ground and on at least a couple of concrete piers there is also dampness about 4 or 5 inches off the ground.
Other than that, it seems dry. I didn’t see any standing water and it did not look like any water had actually been down there. I’ve never seen dampness on the concrete before. I am both confused and worried. Should I be?

Are homes in the coastal areas of North/ South Carolina available with crawl space foundations?
We are considering relocating and I definitely do not want a slab foundation. Everything I have researched online shows a slab foundation.

Which is cheaper, a block foundation with crawl space or a pier and beam foundation for a room addition?
November 13th, 2011 at 1:36 am
can you add a garage addition if you have a crawl space foundation?
Its on a ranch house, standard crawl space from what I know. We’re wondering if you can add a 2 car attached garage on a slab foundation with this scenerio.
Also, if you could give me a vague idea of how much this might cost, that would be great.
Thanks!

Could I get an approximate cost of replacing 3 sides of a concrete block crawl space foundation wall?
The total length of the wall is approx. 90 ft.long and 36 inches tall. I need it excavated and replaced and backfilled.
I need a cost for having a contractor do all the work.

For a house, is it better to have a concrete foundation or a crawl space underneath the house?
We are looking for a house and wanted to get people’s opinions. Are there pros and cons?

How much cheaper is a slab foundation compared to a crawl space foundation?
November 13th, 2011 at 5:33 am
unless that includes a decent lot, that’s pretty high for a nearly 20 year old DW
Sold for 61K less than a year ago before updates in a bad market on 1/2 acre?
WAAAAAAY high. Give them that number and ask them what they REALLY expect to get.

Do you mean a slab foundation or a crawlspace? A concrete foundation can give you a crawlspace if it has concrete walls extending above the ground. That would be my first choice, concrete foundation walls, decent crawlspace underneath. I don’t like a house sitting right on the ground. In my relatively damp climate, that means that water has too much chance to get at the wood the house is built of. If there’s going to be a crawlspace, best to have it tall enough to move around in easily. Part of my house, unfortunately the part with things in it that might need looking after, has a crawlspace that gives me claustrophobia when I have to go into it. My last house was on a concrete foundation and was part full basement and part crawlspace since it was on a slope. The concrete was completely solid around the outside, which was a blessing when rats arrived in the community. They just couldn’t get into that crawlspace.

Wouldn’t that be a slab of concrete with concrete block piers for your floor beam. You can frame above the beam or put down strong panel and pour your finished floor.
November 13th, 2011 at 10:25 am
I would think the pier system would be cheaper but you should get estimates for both. I think the block foundation would be better if your in a cold area. It would keep the wind off the floor and you would be better able to insulate it.

access and your houses cond. are key. Your footings might be inadequate . Did they contribute to the wall failure? You need to get a back hoe in there .do you have room ? You will need to replace your perimeter drains. the materials needed to do this job are not a big factor in pricing it. the labor involved could vary a great deal sorry I can,t offer the help you need

Bathroom remodel help- ceramic tile with crawl space foundation?
We would REALLY like to put ceramic tile down just because its more durable and water proof BUT this is a crawl space foundation in Oklahoma… if your not familiar with this, the soil is mostly clay and the house shifts during hotter and colder weather. The house was built in 1977 so its fairly older and already has settled and has a few hair line cracks above doorways. The previous owners put ceramic tile in the kitchen recently and the grout is chipping out and my guess is because of the shifting of the house. My grandma always had ceramic tile in her entry way and the tiles actually broke into pieces after a few years. Is there any way to put ceramic tile down with out this happening on a crawl space foundation here? Or would you say viynl tile would be the best way to go. I absolutly HATE linolium… but which one would be the best? I have read though that viynl tile in a bathroom is a bad idea because moisture will get through the cracks and cause it to rott again… any help?
Thats all fine and dandy about laying the concrete board, BUT the house shifts, if it breaks ceramic tile, it will break concrete board too right? Because I am thinking so. Slab foundations in this area break because of the soil below them, so I dont think 1/2 inch conrete board would hold up… I am asking, is there a special way to install it like you have to install natural stone because it expands with heat and shrinks in the cold?

What is a good price for a contractor to pour a crawl space foundation on a 2,040 sized modular home.?
November 13th, 2011 at 7:58 pm
Yes you can; the garage slab will be separate from the crawl space.
Cost will depend on a lot of things, size, type of roof attachments, your area, etc.
November 13th, 2011 at 8:30 pm
20$ is a real good price, but I dought any one will do it for that .
Get multiple bids on the job. Some contractors will bid high on jobs that they don’t want to do, so if they do win the bid, atleast it worth there hastle in doing it.
November 13th, 2011 at 9:56 pm
Try lamiate flooring. It is not really expensive, looks great, and it floats, so it won;t be bothered by minute shifting.

There are far too many variables to give you a definitive answer. Many people assume that a slab foundation is cheaper than a crawl space, but that is not necessarily the case. A lot depends on the area of the country in which you live and the soil type. A slab may be cheaper in Florida or much of Texas, but may actually cost more than a crawlspace in northern climates. In the end, you need to consult your local builders for opinions and pricing.
Good luck with your search for information.
