WATER BOREHOLE DRILLING. In carrying out borehole drilling projects in Nigeria, I strongly advice every prospective client to assign a geologist with his borehole project. it is important for the client to also beware that we have different borehole types depending on your water need and affordability.

We have Direct shallow borehole and industrial(deepwell) borehole. Each one of these borehole types is designed to serve a particular purpose different from the other. In carrying out a drilling project, whether in the basement complex or sedimentary terrain, certain factors like underground water contaminants, depth of the fresh water aquifer, productivity of the well, septic contamination, mineralogical composition of the project site, salinity and so on, should be taken into consideration.
Note: A Geo-physical survey is highly recommended.

Geo-physical survey is a scientific method of acquiring geological and hydro-geological features of the earth through some standard recommendations and adopted applications. The acquisition data helps both the client and the geologist to make a better judgement.

1) Direct shallow borehole: This borehole type is the most common within lagos and its environs. It is the least expensive of all borehole types, the reason why it is called shallow borehole is because the borehole is not drilled to a far depth, it has active production sustainance and it is economically very affordable. In some challenging environments like victoria island, lekki, ikoyi, ajah, lagos island, satellite town, sango-tedo, etc. There is the possibility of saline contamination,sewage infiltration, organics, hydrogen sulphide(H2S) and run-off incursion in the shallow bed. It is therefore advised that water treatment plant be installed for safety, human health and environmental pressure

2) Industrial or deep borehole[/b]: This borehole type is the most reliable in terms of production capacity and resistance to contaminants infiltration. The aquifer is confined and deep depth located. This well production possess industrial capacity, the confine nature of the aquifer is safe from all quality interference . It is the most reliable of all the borehole types and is specially designed for bottle or pure water processing factories, large residence, hotels and high rise buildings, production factories, community water schemes,etc. The deep borehole is the most expensive of all the borehole types, because of the depth and the nature of materials involved in the drilling operations.

we can work both in BASEMENT AND SEDIMENTARY REGIONS

GEOTECHNICAL INVESTIGATION (SOIL TEST)
The soil is the most important yet most neglected in a construction project. All structures, buildings, roads, bridges, dams and even life itself is based on the soil. The soil is the natural foundation that supports all structures and investment. Most clients see soil investigation as a waste of fund despite being the cheapest in the construction process, hardly is the cost of soil test up to one percent of the cost of construction. Some contractors too, ignore the importance of proper soil investigation and analysis and base their design on assumed bearing capacity and rate of settlement.

Soil test helps to determine varying physical and chemical characteristic of soil, which can vary from place to place and from layer to layer even within the limits of the proposed structure. Soil characteristics can change considerably within a small area. Weather, climatic changes, and site management can in the future affect the bearing qualities of the soil, if the foundation is not designed properly to the bearing capacity of the soil, then they will fail and so will the building. This is as important as the entire project itself that may cause long term complications and may result to loss of life and property, endanger residents, tenants and damage other neighboring properties. The extent of exploration depends on whether the area is built up or not and size of the structure.

The soil investigation help to determine the following:

1. Bearing capacity of the soil which determine the load sustenance capability of the soil,
2. Rate of settlement of the soil which affect the rate at which any structure placed on it settles,
3. To select a type and depth of foundation,
4. To select suitable construction technique ,
5. To predict and resolve probable foundation problems,
6. To determine if the land can be subjected to subsidence and cause sinking of the building,
7. To determine water table which affects humidity within the foundation and greatly affects the character of a soil which varies considerably with water content, mineral or chemical component of the soil that might affect the choice of construction materials. For example if the soil found to contain sulphur it can attack our foundation, therefore sulphur resisting cement must be used in the foundation in such soil.

Whether you're working in peat, gravel, clay, silt, sand, or loam soil, understanding the soil properties of your site help you make good construction decisions leading to success of the project. The structural engineers can efficiently and accurately design the structural elements required based on the results of the soil test analysis so that for long term viability and soundness of the project. The result also helps to determine whether there is need for soil stabilization and the foundation depth to attain the required bearing capacity.

All intending property owners or real estate investors should note that for a small sum of money you can protect, possibly the largest investment of your life. Without soil investigation buildings can collapse or rendered non functional for intended purpose. Why risk the expense for the cost of a soil test? Being aware of any problems will enable you to determine future costs and help you to make vital decisions about the suitability of the land for building. The design will match the site conditions, give you peace of mind yet will reduce the risk of over design thus saving you money.

PILE FOUNDATION: pile are used to support the ground in unstable soil where a large structural loads are involved. Piles are driven into the ground by pile drivers, machines usually of a high frame with appliances for raising and dropping a pile hammer or for supporting and guiding a stream or hammer.
Pile foundation are used when the soil is cannot support the weight of the building or if the building has very heavy, concentrated loads, such as in a high rise structure, bridges or water tank.
Types are end bearing pile and friction pile
In end bearing piles, the bottom of end of the pile rest on the layer the strong soil or rock. The load of the building is transferred through the pile onto the strong layer.
And in the friction piles, the load transfer s the load of the building to the soil across the height of the pile, by friction, thats is the cylindrical sharp works to transfer the forces of the soil.
