Soil reactivity refers to how much the soil on the building site is likely to expand, contract, shift and settle (normally as a direct result of changing moisture content). This is a real issue, its why the report and the engineering specifications that derive from it are mandatory for all construction. The structural engineer will consider the ...
Reactive soils are considered by engineers to potentially give rise to a certain degree of movement that can be thought of as a range although it has geometric properties that complicate this but in simple terms a "Class H" soil, that is a heavy clay is expected to move some 40 to 60mm at the surface under normal seasonal conditions - that is without any significant extraneous influences.

Building on reactive soil sites will need to do a special assessment and advise on how to safely build a house without the risk of damage due to soil movement. In many cases, this will involve installing concrete piers or screw piers into the ground Trees and site maintenance for reactive soil sites Trees and their roots are often theget price.
Soil reactivity is defined by how much the earth on-site or perhaps on a specific place is probably going to move, expand as well as contract due to alterations in moisture content. Building on reactive soils can be a serious problem especially when this concerns layer of concrete subfloors or if perhaps the venture will involve creating multi-storey buildings.
Soil reactivity refers to how much the soil on the site is likely to move, expand and contract (normally as a result of changing moisture content) and is graded by class. The soil bearing capacity tells us the weight the soil can support per unit area and determines the type of footings or slab subfloor that can be built on your site.
07-07-2020· City neighborhoods have been built upon man-made fills. There are other unusual soils that present challenges to construction, such as chemically reactive or lateritic soils. It is the job of the project engineering team to determine if it's appropriate – or even possible – to build on these atypical construction sites.
The classification of deep reactive soils is broken down as follows by AS2870: » M-D: Moderately reactive clay or silt sites, which may experience moderate ground movement (21-40 mm) from deep-seated moisture changes. » H1-D: Highly reactive clay sites, which may experience high ground movement (41-60 mm) from deep-seated moisture changes.
14-01-2016· Soil reactivity refers to how much the soil on the site is likely to move, expand and contract (normally as a result of changing moisture content) and is graded by class.
