Constructed beach houses – different types and constituents of foundations

When examining the different types of foundations, we first look at the foundations of the raft. The raft foundation is basically a large concrete slab designed to cover the entire area or part of the area. So soft or weak on natural soil or on surface soil or soil that is prone to descent as in mining areas or where the column is tightly separated so that their base may be closed, touched or overlapped, – the location one percent can be covered. Although the ground cover is used on poor soil, it can not be used for Jamaica beaches, which require a much more solid foundation.

Types of Types

The solid raft consists of a solid two-way reinforced concrete sheet. Light rafters are used for low-capacity buildings or low-wheel lightweight frame constructions. Heavier and larger buildings are used thicker and deeper rafts.

The beam and the deck pallet are located directly on the ground. It is useful if the load or rigidity requires a sheet of three hundred millimeters thicker. This was experimented with on some Jamaica beachfront property, but the concept was quickly dropped

The Cellular Raft consists of top and bottom plates (rafts) that form hollow cells in both directions. This is useful if the start ups are high and the low stiffness (nine hundred millimeters) is required to achieve greater stiffness.

Sometimes the depth can be full basement or brick reinforced concrete walls, monolithic, floor and rafters.

Pile basics

Fluffy foundations are those that transmit loads to deeper levels through long columns embedded in the soil. They are suitable for low-capacity soils where the water level is high where shale can be cured or other surfaces near the surface that can be trained. This is what most Jamaica beachfront properties are used for.

Types of Piles

Friction piles are transmitted by the friction between load and ground to the surrounding ground, ie the piles are supported by friction between the soil and the piles. End cap piles apply a bearing between the following layers through weaker layers.

Long-stacked piles are relatively short-length layers used in shrinkage clay as underlying moisture movement zone. Generally they are large in diameter (three hundred millimeters) in comparison to their short length, so generally there is no need for steel reinforcement and rigid.

Factors determining the width and depth of the bases

The width and depth of the base change with the following:

o The nature of the subsoil

o The weight of the wall and the load it carries

o The nature and strength of materials used in the design of foundations; and

o Probable behavior in soil load on which the foundation rests

Concrete in Foundations

Concrete strength is influenced by a number of factors:

1. Ratio and type of cement

2. Type, ratio, classification and aggregate quality

3. Water content

4. Accuracy of mixing, mixing, transporting, depositing, compressing and welding concrete

Most concrete concen- trations contain ordinary cement, though this may vary in particular circumstances. The standard standard mixture is 1: 2: 4.

Basic Selection Factors

o Soil Status

o Type of structure

o The structural load economy of the type of foundation

o Time available for construction

o Life of the building

o Future Use of the Building


Settlement is the vertical downward movement of the Foundation on a Compressible Soil

. Consolidation of soil particles

2. Reduction of the moisture content of some soils that collapses after drying

3. The general movement of earth for various reasons

4. Overloading the Earth

The Foundation's most important aspect of Jamaica's seaside homes, no matter how good the plan is, will not stand up if the foundation is weak.
