Building On Granite Bedrock

I d planned a full basement with 2 storeys above all icf walls up to the top plate.

Building on granite bedrock.

The foundations are reinforced concrete strip foundations in fairly good weathered granite gravel soils. 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. Fortunately no blasting is required to dig into the rock. 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.

Having already spent time and money on. The granite must be stable it cannot be flaking or crumbling away. They re also ideal in your case. 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.

If the lot that you are thinking about building your cottage on is waterfront then chances are that the rock will be slopping towards the water naturally. Posted in observatories. The lot where i m building my new home is quite rocky. The problem i have.

I d say 3 trying to put a foundation in bedrock only creates a bathtub effect full of water. The deck would be inset into a 6 foot deep 14 foot wide u shaped space at the back of our house approximately 8 feet above the ground. The bedrock vibrates a lot less than sediments because of its structure. It is much more compact than the sediments which are composed of multiple thin and inhomogeneous layers.

Crawl spaces are not useful imo. If everything is solid and secure then you can set the concrete walls or concrete footings right on top of the rock. This is like macro dental work. Building a foundation on fill is no way stable enough to give me a secure solid feeling.

Here you can see that a wide footing area has been formed over bedrock. Indeed in some places the bedrock is exposed i am thinking. Hi im building a house next summer in atlantic canada 700 200m from the ocean. We are currently building a long 60m double story building with two expansion joints at aproximately 20m.

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. The deck footings will be sitting on bedrock with about 18 24 of back fill because our house footings are also built on bedrock. The soil cover is somewhat thin perhaps only three feet deep at most.
