Common problems and anomalies

piscinaPools and water tanks
– Infiltration through cracks in the waterproonfing layer
– Presence of cracks caused by building failures
– Soil deformation and structure movement
– Leaks in the enveloping pipes and drains

 

Floors and pavements
– Presence of cracks caused by building failures
– Failure in the sealing of the expasion joint
– Empty Existence under concrete slabs
– Presence of active and passive cracks on hard floors

 

subsoloUnderground and Basement
– Infiltration from concrete joints and expansion joints
– Cracks caused by traffic excessive and aggressive chemicals
– Presence of cracks caused by building failures
– Soil deformation and instability of the water table level
– Water percolation in diaphragm walls and wall of sheet piles

 

laje Foundations
– Water penetration through the anchor blocks of the rods in retaining walls
– Infiltration from concrete joints and expansion joints
– Presence of cracks caused by building failures
– Water percolation in diaphragm walls and wall of sheet piles
– Soil deformation and instability of the water table level

 

barragem Dams
– Water percolation through the prestressing cables of the trunnion beams
– Water infiltration through the cracks in the spiral case and in ring gallery
– Water infiltrations between the cone of the suction tube and the concrete anchor block
– Water percolation through the cracks and located joints in the powerhouse

 

tunel Tunnels
– Infiltrations caused by failures in the waterproofing system of tunnels
– Active and passive cracks that allow the penetration of aggressive agents
– Percolation of water through concrete joints and expansion joints
– Areas with high porosity in the concrete allowing infiltrations
– Infiltrations in the tunnel emboque and in connection with stations

 

saneamentoSanitation structures
– Presence of cracks caused by building failures
– Water percolation through the expansion joints, type “fungenband”
– Water infiltration between the metal inserts and concrete walls
– Water infiltration in the joint between the floor slab and the concrete wall
– Areas with high porosity in the concrete allowing infiltrations

 

viadutoBridges and Viaducts
– Active and passive cracks that allow the penetration of aggressive agents
– Presence of cracks caused by building failures
– Cracks caused by chemical reactions in concrete as the alkali-aggregate reaction
– Existing discontinuities in submerged elements such as blocks and stakes
