The secret to underpinning a basement of a building is, undoubtedly enough, supporting the existing building. Even while we excavate away the ground beneath the building we have to ensure that the building above does not move or settle at all. To do this we need to ensure that the mass of the building is moved via appropriate structures to solid ground at all times.
An approach we commonly use is called “Underpinning” and for that we need Basement Underpinning drawings and permit in Washington DC. Really merely this includes excavating underneath the existing foundations and extending them downwards. Naturally, we don’t try to do the entire structure at the same time rather we do a small area at a time. The size of these areas depends very much on the website in question but are normally about a meter broad and a meter deep.
This is the most crucial phase of a basement project and needs to be very carefully carried out and kept track of. When we have meticulously excavated an area by hand, we can then add steel reinforcing rods around which we pour concrete. Using this technique we can ensure that the prolonged structures are far stronger than what was there prior to.
While the first section treatments we then move off to a different area of the structures and excavate another area by hand and repeat the process. In this way, the house is gradually extended downwards while staying completely constant and still. Once the foundations are protected the excavation can be processed at full speed.
