Whisper-Grip® was used for the irst time in Malaysia in 2007. Since then,

The solution involves the removal by milling of an area to the left and right
of the crack to form a strip extending approx. 10 cm across and a depth of
approx. 3-5 cm. The crack itself is pressure-injected with the l exible resin 3-5 cm
sealant MC-Injekt 2300 top. The milled strip is cleaned and primed with the
low-viscous epoxy resin MC-DUR 1200 VK. It is then coated with the l exib-
le, crack-bridging EP-PUR combination MC-DUR 1291-l ex. Finally, the MC
crack-bridging coatings and the entire l oor area – for example in a multi-
storey car park – are coated over with MC-DUR 1200 VK and MC-DUR 1252.
MC crack-bridging coatings have already been successfully used in many
multi-storey and underground car parks in which other solutions have pre-
viously failed, for example in the underground car park serving the Riem Crack pressure-injected
