But sometimes rot sets in early, with a curious result. Certain types of wood, like cypress, have a surprisingly long lifespan when set in the ground as a foundation and can remain structurally sound for 100 years or more. The piles are often milled tree trunks that rely on the friction between the soil and buried surface area of the pile for stability. A coastal pile foundation, for example, is well suited and frequently used for waterfront locations that require an elevated floor level due to a flood-prone site. Also, every region has a customary local foundation type. Each is chosen by the architect or builder based on a particular site’s topography and soil, along with kind of structure the foundation will support. Quality construction starts with a solid and consistent foundation.There is no single, perfect foundation type. When dealing with varying lot conditions Stem-Walls are a much more consistent method of foundation construction. This process takes a bit longer than the Monolithic Slab, but a more stable foundation will prevent other issues down the road that could arise with trusses or wall construction. This type of foundation is much more stable when fill dirt is required achieve the final build elevation. Stem-Wall slabs are constructed in a multi-part process where a footer is poured at virgin ground level, then blocks are laid forming a wall up to the finished slab elevation. This cracking can cause structural issues which affect other aspects of the house further down the building process like drywall and flooring if the framed walls aren’t stable.įor these reasons, most lot builders in Florida (including us) prefer stem-wall foundations. In this situation, Monoslabs tend to crack around the perimeter walls and other major load bearing areas. This is a problem for homes that need to be built up to rise above a flood plain provided by your engineer (as most lot builds in Florida must). They can not be used when a lot of fill dirt is required because the concrete is more likely to crack if the ground isn’t compacted well enough. There are some major issues that can arise if lot conditions are not conducive to a Monolithic Slab. In this case, if all finished floor elevations are the same from lot to lot and there is very little slope, Monoslabs may be the best choice. In most sub division community builds, the ground is level throughout the entire property and more densely compacted with very little fill dirt required. When used under the right conditions, Monoslabs can be just as sound as Stem-Wall slabs. Because this Slab is poured all at once, it is much faster and keeps labor costs low. Monolithic means “all in one pour” so the foundation is constructed in one single pour that is made up of a concrete slab with thicker areas under load bearing walls and all perimeter edges to take the place of footers. In this article we will explore the differences and benefits between the two types of foundations. Both carry specific benefits and challenges during construction and it is important to know these before breaking ground during a new home building project. There are two types of foundations predominantly used during the construction of a new home Stem-Walls and Monolithic slabs.
