CRACK INJECTION - SHAKES AND SPLITS

Shakes and splits can develop in timber beams for a variety of reasons. Their presence can lead to more serious complications. De-Pest have crack injected timber beams, whether glulam or solid timber, in a wide variety of climatic conditions. These range from moisture saturated enclosed swimming pools, wind and sea blown Links Golf club structures, to the scorching dry heat of the Middle East.


WHY USE CRACK INJECTION?

  • Improves fire resistance
  • Improves resistance to weathering
  • Improves mechanical performance
  • Prevents parasitic attack
The process of crack injection is undertaken when no further significant changes in moisture content are envisaged.
