What is a Basement Extension?
The popularity of basement extensions has increased in recent years due to the premium that comes with this venture. These spaces have been transformed from simple storage rooms into proper living spaces for the whole family. It might make economic sense to transform your basement or cellar to add value and living space in your home. Basement extensions can add significant usable space to your home. A professionally constructed basement can be used as an office, a playroom, a bedroom, a basement studio, a home office or a home theatre. A basement extension can add up to 30% floor space to your home and will add value to your home (usually 30-50% more than the basement project cost).

Usually the grouting method is used to stabilize ground weaker in nature. Grout is a kind of fluid form material for injecting into the sub-soil. The material can be of cement or chemical base. It can get hydrated inside the soil and make the subsoil much stronger to withstand itself or to resist penetration of ground water. |
Incorporating a basement into your extension project can be a cost effective way of gaining a significant increase in floor area with a relatively small increase in the overall building costs. The newly constructed basement acts as the foundations for the extension and therefore the additional cost of the basement will be in the region of 10-20% of the original project cost. Basement extensions added during refurbishments or rear/side extensions are a cost effective way of adding significant living space. Additionally, basements improve the energy efficiency of homes. Heat losses through basement floors and walls are less than those at ground and upper floor levels. Research carried out by BRE found that given two houses of the same above-ground size and construction, the one with a basement would be 10% more energy efficient. Living space below ground also offers excellent sound insulation, particularly where a suspended concrete floor is used at ground level. Construction of Deep Basements and Large Underground Structures: Following provisions should be made while constructing or extending a basement:

Cut-off Walls:
Constructed using sheet piles, soldier piles, hand-dug caissons, lagged piles, pipe piles, or diaphragm walls. Using Pipe-Pile as Side Support: After the steel piles/tubes are driven into the ground, steel bars will be inserted into the pile and then grouted. It is a relatively cheap but strong support system, suitable for use in excavation support up to 12m deep. |
