House Underpinning Cost refers to the cost incurred in strengthening the foundation of any given construction. Underpinning may be necessary for a various reasons, which also have a bearing on the house underpinning cost, such as the original foundation is simply not strong and stable enough, the usage of the structure has changed, the property of the soil supporting the foundation may have changed possibly through sinking or changed during building construction, the construction of nearby structures requires the diggings of soil supporting existing foundations, to increase the depth or load capacity of existing foundation, to support the addition of another storey to the building above or below.
It is more economical to work on the present structures foundation than to build a new one due to land price or many other reasons, and Earthquake, flood, drought or other natural causes have caused the structure to move, thereby requiring maintenance of foundation soils and/or grips.
Underpinning may be accomplished by encompassing the foundation in penetration or in extent so the foundation rests on a more supportive soil layer or allocates its load across a larger area. Use of micro piles and jet grouting are common methods in underpinning, an alternative to underpinning is the strengthening of the soil by the introduction of a filling, which includes increasing urethane based engineered structural mastics. Underpinning may be necessary where p-class problem of soils in certain areas of the site are faced.
There are a few different methods used for house underpinning and each result in varying house underpinning cost.
Traditional underpinning is the concrete underpinning method, which is nearly 100 years old underpinning method with the same procedure, as earlier. This underpinning method toughens an existing structure of the foundation by digging boxes by hand underneath and consecutively pouring concrete in a tactical order. This underpinning method is applied when the existing foundation is at a low depth and can work well for up to 15 meter depth. This is the method with the least house underpinning cost.
Mini-piled underpinning is used when the loads from the foundation need to be transferred to stable soils at considerable depths, usually in excess of 5 meters. Mini-piled may either be augured or driven steel-cased.
Beam and base underpinning in this is more progressive method of underpinning than traditional mass concrete underpinning. In this steel-clad concrete beam is built underneath, overhead or as a replacement of the existing foothold. Design of beam depends upon the configuration of the building and the load applied on it.
In this method, the foundation ground beneath footing is vaccinated with a mixture of structural resins and hardener. When this mixture enters the ground, the resin and hardener mixture starts expanding due to chemical reaction. This helps in fixing any vacuums and cervices, if dense feeble soil injection continues it levels the above soil.
To know the exact cost of underpinning, you can consult your builder or you can search on the internet. Get the house underpinning done at the right time, so that the foundation of your building stays strong and there is no serious damage caused to your property.
