The surfaces can be passivated with polymers but existing damage probably cannot be repaired.
The joint doesn't prevent expansion and contraction but it limits the damage caused by thermal stress. It allows room for the concrete ( or steel ) to expand and contract without creating the severe cracks that would form without them.
Windmills capture electricity from a renewable source, the wind, without releasing any greenhouse gas emissions into the atmosphere. The present buildup of greenhouse gases is causing the enhanced greenhouse effect which has caused global warming. Renewable energy is the way of the future!
The land is contoured to prevent erosion. Topsoil is replaced, and seeded/planted to grow new vegetation. Provision is made for drainage of rainwater. Current mines are required to reclaim mined land, and funds are provided to reclaim older mines.
Structural geologists look at features in rock caused by deformation, that is, by the action of forces acting on and within the earth's crust. These structures include faults and folds, which significantly affect the strength of rock and must be considered in the construction of tunnels, buildings, dams and other engineering projects that rely on that rock for their foundation.
Motion of a fluid (liquid or gas) caused by density changes caused by temperature changes.
Types of pollutants caused by a limestone quarry are:- Air pollution, the dust etc caused from drilling. The process of quarrying limestone causes the air to become polluted. Sound pollution, the sound caused by quarrying from limestone can often heavily impact those living within hearing distance.
to reduce earthquake damage, new buildings must be made stronger and more flexible. older buildings however must be modified to withstand stronger earthquakes

Because the earthquakes in Haiti caused the buildings to fall down.
It depends on what is meant by 'holes'. Cavities in limestone may be caused by both mechanical and chemical weathering.
It caused a lot of damage like destroying buildings
Normal karst processes - it is a major limestone area.
large caves in limestone bedrock
A sinkhole is the term used to describe a depression in the ground caused by a cave collapse. It can also be the result of acidic water dissolving limestone.
deforestation
