MULTI CONCRETE WIT-UH 300
Injection system for numerous concrete applications at the highest load levels.
NEW!
The latest anchor innovation from WĂźrth.
MULTI CONCRETE WIT-UH 300 Injection system for numerous concrete applications at the highest load levels. The latest generation of heavy-duty composite mortars. This hybrid composite mortar system, which was developed internally by WĂźrth, makes highest loads possible even in very low anchorage depths. This expands application possibilities by filigree members and greatly reduces assembly time and material costs.
The concrete fastening solution for all kinds of applications. WIT-UH 300 is perfectly suited for fixing heavy loads in cracked and noncracked concrete. The new all-round anchor is the ideal solution for postinstalled rebar connections.

MULTI CONCRETE WIT-UH 300
Variable anchoring depths. Can be flexibly adjusted to your individual assembly situation.
High performance even at highest temperatures. Temporarily thermally stable at temperatures of up to +160 °C! Optimal for connections that are exposed to extreme heat (e. g. in paint shops). Read more about the three temperature ranges on page 9.
Cures in just 30 minutes!1) For efficient project planning and implementation.

A minimum anchoring depth of 75 mm is needed for the injection system W-VIZ to still reach a load of 11.1 kN. Using the WIT-UH 300 the drill hole has to be a little deeper. The WIT-PE reaches its maximum load at 8.6 kN (max. anchoring depth = 144 mm).
