As water moves against barrier walls it pushes its way through cracks and joints and defects in the walls. As the water flows in and out of the walls it carries sand and soil with it which causes undermining of the structure, voids to form and deteriorates the structural integrity of the barrier wall.  This cycle is exacerbated during periods of heavy rain which continues the erosion of the soil.

The Solution

Polyflow Concrete solutions can inject polyurethane foam to react with existing water that is penetrating the barrier wall to seal and stabilize and prolong the life of the wall.
