Pad Foundation Pad foundation refers to the foundation which is intended for sustaining concentrated loads from a single point load such as structural columns.
Administration at the Local Government. And what does it mean for human resource? The raft foundation supports the overall structure, or a part of it for example the basement as a continuous structure. Unlike the flat foundation, which is not suitable in places where the ground water can be expected to appear, the raft foundation can absorb the load resulting from the pressure of groundwater.
By uneven surfaces, this technology is also a good choice, because it provides more stability. It is much easier to insulate around, than the strip foundation, this way the linear thermal bridges can be reduced, by passive houses definitely the raft foundation should be chosen.
An important consideration is that it can implemented in a single phase, unlike the strip foundation see image above. Namely raft foundation is more profitable by houses with basement. Regarding to the many benefits of the raft foundation, the difference is not that significant, so you should consider this technical solution as well.
The most important thing is to take in consideration the building, construction and terrain conditions, and the consultation with the static expert should be all the foundation of your decision and your house as well. HEYYA, I want to construct a 4 storey building commercial 2 floors, residential use 2 floors on soil which has 3m sand on top and 10m clay below, what foundation do u suggest for this 4 storey steel structure? Many thanks!!! Hi I want to build a house with 2 floor, which foundation do you think is better taft or strip?
Yours, Waleed. Article search Choose Strip foundations are normally used when ground conditions are good and mass concrete can be used. For a standard external cavity wall of mm mm block, mm cavity, mm block , a strip foundation would need to be mm wide. Some builds may require more concrete or the use of steel reinforcement within the concrete itself.
Strip foundations are usually the easiest and least expensive of the foundation systems used in Ireland. Unlike the strip foundation, raft foundations are used where the ground may be stable, but the bearing capacity is low, like boggy land, wet ground or where soils have been imported to site.
Concrete for raft foundations is poured over the total area of the house, making it look like one big concrete slab. Raft foundations must be specifically designed and constructed, meaning it should only be installed by competent contractors and supervised by a qualified architect or engineer. The finished raft foundation can support numerous columns and walls, spreading the load across the slab and ground floor area, and lowering the contact pressure.
Raft foundations are typically used for large loads, when the soil has low bearing capacity, when the footing to total floor space ratio is high or when building walls are in close proximity to each other and may overlap. A pile foundation is strong material in the form of concrete in the shape of a cylinder. This cylinder is pushed into the ground to support structures that sit on top of it. Pile foundations are used when there is low bearing soil at the surface the load is transferred to stronger ground found deeper, such as rock or stronger soil , or when the construction has very heavy and concentrated loads think sky rises, bridges etc.
