Soil is a heterogeneous accumulation of unconsolidated sediments and deposit of solid particles derived from the disintegration of rock. This is typically important when you are trying to find homes for sale Montego Bay, Jamaica gated community. The soil in areas of housing schemes should be cohesive.
A soil is a loose mantle of mineral and organic matter of varying thickness that covers most land. It is formed under the combined influences of physical, chemical and biological activities
Soil is the comparatively thin layer of disintegrated material overlying the rocks of the earth's crust. Soil in Jamaica can be classified as cohesive or fine-grained, non-cohesive or coarse-grained and organic. Clay and silt are classified as cohesive or fine grained, sand is classified as non cohesive or coarse grained and peat is classified as organic.
Properties of Cohesive Soils
* High water holding capacity
* Small air spaces
* Water drains poorly
* Soil stays wet
* Considerable strength when dry
* Low strength with high moisture content
* Tends to be acidic
* Smooth and greasy to touch
* Shows high plasticity
* Grain sizes are small
* Particles not normally distinguished by the naked eye
* Exhibit cohesion between particles
* Dry slowly
* Shrink appreciably on drying
* Particles have flat, plate shape; flaked-shaped; needle shape
* Capable of holding a film of absorbed water on their surfaces
* Grain size are smaller than 0.001
Properties of Non-cohesive Soils
* Do not exhibit plasticity
* Tend to lack cohesion or negligible cohesion between the particles
* Little change in volume with variation in moisture content
* Cannot be molded
* Require pick axe for excavation
* Have large voids that permits easy drainage of water
* Less susceptible to capillary action
* Large air space or larger voids
* Water drains easily or frees draining
* Good bearing capacity
* Slightly compressible
* Permeable
* Particles are visible with the naked eye
* Feel gritty to the finger
* Space between the particles is large
* Get its strength from friction between the particles
* Allow water to percolate through them much easier than cohesive soil
Properties of Organic Soils
* Retain water
* Have low strength
* High moisture content
* High acidic content
* Derived from plant and animal remains
* Will absorb large quantity of water
* Increases in pressure to this soil cause large volume of water to be expelled
* Coarse fibrous texture
* Dark color
* Very smelly; odor often intensifies by heating
* Low bearing capacity
* Very compressible
With the different soil types that are available, when building foundation one has to be careful that they are building the right foundation on the available soil. This is proven with the homes for sale Montego Bay Rose Hall, St James which are built on strong foundations.
The following gives you an idea of what foundation types are suitable for what soil types.
1. Soil type of sand, gravel or rock with small portions of clay and silt - This is suitable for shallow strip, pad or isolated column and surface or solid slab raft, foundation type.
2. Soil type of uniform, firm and stiff clay - Suitable for strip, pad or isolated column, short-bored piles and beam and solid slab raft, foundation type.
3. Soil type of soft or soft silty clays - Is suitable for wide strip, inverted 'T' beam or variants of the raft foundations depending on soil bearing capacity of the soil.
4. Soil type of fill (made-up ground) and peat - This is suitable for pier, end bearing piles, or variants of the raft foundations depending on bearing capacity of the soil.
