Crawl spaces are not useful imo.
Building on granite bedrock.
The lot where i m building my new home is quite rocky.
Posted in observatories.
The white arrows are pointing at green epoxy coated steel rebars 1 in diameter that are set in epoxy into drilled holes within the foundation lines.
If everything is solid and secure then you can set the concrete walls or concrete footings right on top of the rock.
The bedrock vibrates a lot less than sediments because of its structure.
Fortunately no blasting is required to dig into the rock.
They re also ideal in your case.
Indeed in some places the bedrock is exposed i am thinking.
I recently excavated my site for new construction and i m on exposed granite bedrock for the entire footprint.
The soil cover is somewhat thin perhaps only three feet deep at most.
It is much more compact than the sediments which are composed of multiple thin and inhomogeneous layers.
Here you can see that a wide footing area has been formed over bedrock.
Building a foundation on fill is no way stable enough to give me a secure solid feeling.
What is the best way to build a pier on bedrock.
The granite must be stable it cannot be flaking or crumbling away.
This is like macro dental work.
We are currently building a long 60m double story building with two expansion joints at aproximately 20m.
Insulated concrete forms icf are ideal for building foundations like yours on bedrock because you can custom cut them to fit the unique contours of the rock.
The area is on a bay and reasonably protected but the weather and the wind do kick up from time to time the ground is only a few inches deep literally before one hits bedrock.
I d planned a full basement with 2 storeys above all icf walls up to the top plate.
I d say 3 trying to put a foundation in bedrock only creates a bathtub effect full of water.
Having already spent time and money on.
Hi im building a house next summer in atlantic canada 700 200m from the ocean.
The foundations are reinforced concrete strip foundations in fairly good weathered granite gravel soils.
Buildings on solid bedrock tend to shake less than buildings on sediments or reclaimed lands because the bedrock itself shakes less than sediments or reclaimed land.
The deck footings will be sitting on bedrock with about 18 24 of back fill because our house footings are also built on bedrock.
This is called pinning the footings to the bedrock.
