pipe sealing and repair


If you are responsible for maintenance for an irrigation district or a municipality we need to talk.

Pictured above is the outflow tunnel for the Concunully dam. Constructed in 1908 the tunnel was starting to show its age. Holes and fissures in one section had begun to erode the supporting soil. A void of roughly two cubic yards had opened up threatening the structure.

Working on short notice due to the season SlabJack Geotechnical arrived onsite and after consulting with the engineer, injected a very slow rise but high density polyurethane that completely filled the void but put very little lateral stress on the concrete that in places was only two inches thick.

SlabJack Geotechnical is one of very few companies utilizing multiple polymers to best fit your needs. Fast, medium and slow rise polymers. Three to six pound densities in both non and fully hydrophobic polyurethane.

If you have a unique challenge in your irrigation district or port or municipality give us a call today,


Superior technology, Superior polymers, Superior results.
