CABIN FOUNDATIONS

There are a variety of excellent choices for Cabin Foundations. Let's look at few, starting with the simplest:

STONE PADS:

For details on how to install a stone pad for a cabin see 'site preparation.' A stone pad works great for some size cabins, they are quick, cheap and easy to install. Also should you ever decide to move the cabin a stone pad is easy to get rid of and very non obtrusive. Stone pads are most commonly used on smaller, single story cabins with no water/sewer hookups. As far as the structural integrity of the cabin is concerned almost any size cabin with a standard wood floor will work fine on a stone pad, even most two-story cabins. If you are running water and sewer hookups to the cabin a stone pad is still possible but less popular. The case against a stone pad for some size cabins is the fact that the cabin will float and heave with the land due to natural freezing and thawing and frost. Also many town codes have a size limit for cabins that may be set on a stone pad, it is very common (depending on your location and the size of the cabin) for local code enforcement officers to require concrete piers or footers to place your cabin on.

CONCRETE PIERS:

Concrete piers are generally 18" in diameter and dug into the ground 36" 48". The cabin may be placed on these concrete piers and still have the standard wood floor with 4x4 PT skids and Floor Joists. The exact location and spacing of these concrete piers will need to be coordinated with Wood-Tex so the skids of the cabin rests directly on the piers. The advantages of concrete piers include the fact that it usually very reasonable and efficient from a pricing stand point. The piers extend below the frost level in the ground so your cabin will not float or heave with the frost. This can be an advantage when hooking up to utilities. Also if code requires a permanent foundation this may meet their requirements. The area in and around the concrete piers is usually filled in with clean stone to allow good drainage, be sure the stone is at the same level or below the top of the concrete piers.

CONCRETE FOOTERS:

If the size or design of your cabin requires too many concrete piers to be efficient Concrete Footers may be an option. This is usually a 12" 18" wide trench dug 36" 48" deep, the trench is then filled with concrete giving you a very solid footer. The footers need to run perpendicular to our 4x4 PT skids and are usually placed every 4' throughout the length of the pad. For example if your cabin is 24x48 and has the standard wood floor it will have a total of (10) 4x4 PT skids running the 48' length of the cabin. Your footers would be installed running the 24' width of the cabin so every skid runs over the top of every footer. Again this will keep your cabin from shifting with the frost heaves and can be fairly simple to install. The area between the footers is usually filled in with clean stone, similar to concrete piers.

CONCRETE SLABS:

Concrete slabs may be poured in (3) different styles: Floating Slab, Monolithic Slab or Footer Slab. For more information see: Firm Foundations. The different styles have everything to do with the thickness of the perimeter of the slab. The entire surface area on all three styles is usually poured, giving you a solid surface to set the cabin on. Plumbing such as water supply and sewer hookups must be coordinated with Wood-Tex so everything hooks together smoothly. A solid concrete slab makes an excellent and easy site to place a cabin. Also it will make it nearly impossible for rodents to dig their way under your cabin where they can be a nuisance. Here again it is a good idea to check with your local town to find out if a floating slab is ok or if they will require frost footers.

CRAWL SPACE or BASEMENTS:

Standard cabin floors may be configured to be set directly on a crawl space or basement. The standard 4x4 PT skids are deleted and the Floor Joists are reinforced to carry the additional load. On most size cabins several posts or a weight bearing wall is required in the crawl space or basement to support the additional loading on the floor joists in the center of the floor. The crawl space or basement is generally constructed with Concrete Blocks or a Concrete Poured Wall. The person installing your basement will need to install a Pressure Treated Sill Plate (usually 2x8), this is anchored flat on top of the basement wall, the cabin is the fastened the sill plate. Depending on the size of the cabin and the configuration of the crawl space the cabin can sometimes be delivered directly from the delivery trailer onto the crawl space with no crane. However for full Basements the cabins generally will require a crane to be set or simply to be built on site.
