Living organisms may contribute to mechanical weathering (as well as chemical weathering, see 'biological' weathering below). Lichens and mosses grow on essentially bare rock surfaces and create a more humid chemical microenvironment. The attachment of these organisms to the rock surface enhances physical as well as chemical breakdown of the surface microlayer of the rock.

What effect does alkaline soil have on concrete?
Alkaline soil can increase the risk of concrete degradation through a process known as alkali-silica reaction (ASR). This reaction occurs when alkaline substances from the soil react with the silica in the concrete aggregates, causing the concrete to develop cracks and weaken over time. It is important to consider the soil conditions when designing concrete structures to prevent potential damage from ASR.

What does moss growing on roofing have to do with damage?
There are thousands of different varieties of moss and lichen, but the one that does the most damage to roofing is Ascomycetes Foliose. As part of its life cycle it burrows into the roofing material. On metal roofing this can cause the paint to blister promoting corrosion. The root system can also cause concrete and clay tiles to crack. With moss on the roof the surface is never allowed to dry out. Therefore the roof surface deteriorates faster.
Can ants damage concrete?
Over time, ants can damage concrete. However, if you keep all the cracks in concrete caulked, it will prevent the ants from damaging the concrete.
Should frost damage concrete?
which concrete resist frost action
Will salt water damage concrete?

How does salt water damage concrete?
Salt water can damage concrete by promoting the corrosion of the steel reinforcement within the concrete. When salt water penetrates the concrete, it reacts with the steel, causing it to rust and expand, which in turn causes the concrete to crack and weaken. Over time, this process can lead to degradation and structural failure of the concrete.
Why should defective concrete be immediately repaired on new or old concrete?
to prevent further damage
How can I fix a concrete porch?
