Basements are a fantastic option for building’s space shortages. They are particularly useful where the houses are small and above ground expansions are prohibited due to planning restrictions. Long gone are the days where basements were meant only for car parking or for extra storage purposes. Today basements under houses can house home theaters, gyms, bowling alleys, wine cellars, swimming pools to car collections. However, most of them are still excavated and dug to provide functional living space to the family.
Steps for basement excavation
It is advisable to have a thorough planning before beginning basement excavation, as it is highly important to have a strong foundation for it to be safe and have structural integrity. It is important for the finished basement walls to be high enough above ground so that there is good water drainage and the hole is not too deep. If this is not done then the foundation of the basement will have to be increased in height and this will increase the cost of the basement. Basement excavation can be noisy, dusty and disruptive. Basement excavations are not just limited to one level and can go as deep as a couple of storey. Basement excavation can involve various technically complex construction techniques. And if done incorrectly, it can bring literally the house down. In such a case not only the homeowner suffers his or her own loss but can also be liable for any damage cause to their neighbors’ homes. Thus, it is advisable to have the right insurance coverage and hire a qualified and experienced contractor for your basement excavation.
Make use of the modern technology
Excavators today believe that there are no particular insurmountable and very difficult obstacles in engineering a basemen excavation. Basement digging can be done both by manual labor and with use of hi-tech machines. Digging by hand, being labor intensive is expensive. A surveying transit is an important tool for an excavation contractor. This tool helps the excavator to know how deep the excavation is getting while digging also how level it is. Today modern techniques and equipment allow basement excavations not only in dry areas but also wet areas and the presence of water is now usually not a problem for excavators. In such cases, excavation may take a bit longer as digging out wet clay and sand is more time consuming than digging out dry sand. Few years ago, basement used to be about blocking water i.e. tanking. However, nowadays water is not just blocked but managed. These days, modern systems allow cavity membranes to be built inside the foundation of a basement that further allow the water to drain down through them into a slump from where it is pumped out. Houses can even have two such pumps running, one being a back up for the other in case of any failure. Some of the dirt removed from a basement excavation can be used for landscaping or back filling.
The most important factor driving a basement excavation decision is the cost, as it can be expensive depending on various factors, such as the kind of basement you want i.e. the basement design, the basement depth, the area required i.e. the basement size, where it is being dug up i.e. the soil conditions and land terrain and who is doing it! Digging up all the way down to two to three storey can be an expensive affair. Also, excavating for a partial basement, a walkout basement or a full basement is more expensive than excavating for a crawl or slab space. Certain planning policies at various places limit the basement excavation to a single storey.
