Provides rehabilitation to manhole chambers, wet well, concrete structures associated with drainage asset suffering infiltration or exfiltration.

Non return packers are drilled at predetermined centres and two part acrylic gel is injected to create a barrier.  The acrylic gel acts as a barrier and aid ground/strata stabilisation.  The chamber structure is then sprayed with Monomix HD using ‘Permacast Method’ adding an additional water barrier and increasing the surface strength to 40 npm² (normal C4 concrete 20 npm² – cured).
