In civil engineering, concrete leveling is a procedure that attempts to correct an uneven concrete surface by altering the foundation that the surface sits upon. It is a cheaper alternative to having replacement concrete poured and is commonly performed at small businesses and private homes as well as at factories, warehouses, airports and on roads, highways and other infrastructure.
CPP and CPR methods, developed over the last 40 years, are used in lieu of asphalt overlays and bituminous patches to repair roads when longer lasting solutions are desired. When installing pavers over top of an existing asphalt of concrete pad, there are three installation options: sand set, bituminous set, and mortar set. [1]
Sulfates in solution in contact with concrete can cause chemical changes to the cement, which can cause significant microstructural effects leading to the weakening of the cement binder (chemical sulfate attack). Sulfate solutions can also cause damage to porous cementitious materials through crystallization and recrystallization (salt attack). [7]
Permeable interlocking concrete pavements are concrete units with open, permeable spaces between the units. [ 28 ] : 2 More recently manufacturers have introduced styles with smaller joint allowing for better ADA compliance and still capturing a significant amount of stormwater.
Rising damp from the ground may be prevented by most simple means.

The Drainage anti-slide pile (DASP) is a reinforced concrete structure with a hollow upper section and a solid lower section, designed to resist slope deformation. [ 2 ] [ 3 ] The hollow part is filled with compacted, high-permeability gravels and can drain water via a vertical drain-pipe or sub-horizontal pipes connected to the slope surface.
