Waterproofing Drytech Italia, Montano Lucino Como
Drytech Renovation 1,700 m of joints
RESTORATION OF MOTORWAY JOINTS, VENETO REGION / Drytech waterproofed the joints of an important motorway artery by injecting with DRYflex expanding resin.
The intersections between the ring road route and the existing road network were created via many junctions with underground tunnels. Unexpected settlement following construction made some joints between sections of the carriageway permeable.
Drytech concentrated on injecting the joints with DRYflex expanding resin during the restoration work.
The work did not require the traffic to be interrupted but only a reduction in the lanes.
DRYflex resin can in fact be used effectively in the presence of water so that it was not necessary to drain the area before.
Waterproofing of the movement joints was done with traditional waterstop tapes.
In order to carry out the restoration work any parts falling off were therefore removed, the joints were injected and finally the restoration work was be completed.
As well as being unaffected by water, the waterproofing power of DRYflex resin is not affected by the state of the joints which do not need to be cleaned before being injected. Acting through pressure – and not by adhesion – the resin seals the joints and cracks without sticking to the walls. Due to its expanding quality it adapts to variations in the joint’s thickness caused by the traffic and seasonal thermal expansion.
During this work, Drytech restored 1,700 m of joints between October 2010 and March 2011.
