Types of groundwork foundations
The first step of every building construction is to lay down its foundation. It is the most significant element in any building structure. It is responsible for transferring the loads, managing stability, connecting with the soil, giving strength to the building and more. Even if your house is constructed at an angle of 30 degrees, a good groundwork contractor in London will ensure that it serves best to hold on to your building’s structure.
There are ’n’ numbers of factors that influence the selection of an ideal foundation for your structure. Site location; climate of the area; soil condition; soil humidity; and importantly budget are some major factors. Depending on these factors, there are different types & styles of groundworks in London. Here are some major & commonly preferred foundation types:
This type of foundation is constructed with a minimum of eight feet deep ground level. The structural foundations are placed on the concrete footings that run through the perimeter of the basement; also called basement foundation.
There must be at least 12 inches gap between undisturbed soil and foundation base. After that beams, erected foundation walls, and cement slabs are constructed.
Basement foundation can prove to be expensive groundworks in London. However, it is best for cold climates to prevent the home from moving during the freezing atmosphere.
The most important benefit of this foundation is that it provides extra living spaces and can also double any building’s square footage. It is durable and fire-resistant.
2. Crawlspace stem foundation:
It is made with short walls on concrete footings and has a slightly elevated space beneath a house through which you can crawl. This crawl space can be used for storage purposes or as a furnace.
Groundworks contractors in London prefer this for regions with warmer climates or areas prone to earthquakes and landslides. The elevated floor also prevents house flooding during calamities. Although it is a less expensive foundation, it requires frequent maintenance.
3. Concrete slab foundation:
Monolithic or mono slab foundations are other names of the concrete slab foundation. The construction of this foundation is such that a concrete slab rests on the ground and is poured into a single piece. The major advantage is that it is cheaper and fast in construction.
Also, the procedure of installation of this slab is so sorted and simple. At the depth of two feet, concrete slabs are installed along the perimeter of the slab. Downside the slab construction sewer and drainage pipes are put before concrete is poured.
This foundation isn’t suitable for extremely cold conditions. The benefit of a concrete slab foundation is that it is maintenance-free. However, it can have weak points that could crumble over time due to stiffness.
Professional groundwork contractors in London can help you understand which groundwork is suitable for your building, after a proper study of your site.
Many people consider wood as an unfavourable choice earlier but post the 1960s it became a preferred choice of builders. Commonly builders preserved wood to avoid any kind of decay. Wood foundations don’t require any concrete pouring or massive labour masonry work. They are quick in installation, less expensive and best for dry soil.
An amazing fact about this is that this type of foundation has been found in an archaeological survey in Egyptian pyramids over 6000 years old. Creepy yet intriguing. So if you want your house to last longer, make sure you have only the best groundwork in London for your property.
5. Pier and beam foundation:
Pier and beam foundation or pier and post foundation works the same as ocean pier. The installation procedure of this foundation is time-taking and expensive. However, it works best for areas prone to hurricane, shifting soil and flood-prone zones.
