HOW DO WE DO IT?

HOW DO WE DO IT?

In most cases, for existing structures, chemical injection is done around the perimeter of a foundation.  If there are driveways, patios, decks, or other paved surfaces, ¾ inch diameter holes are drilled through the paving to reach the underlying soils.  The chemical solution is injected to depths ranging from 7 to 10 feet.  The solution is injected at relatively low pressures, typically on two separate days.  The solution is pumped from a truck to a manually operated injection wand.

Injections can be done on the interiors of buildings, however, interior treatment requires that holes be drilled though the floor every 2 feet (one hole for every 4 square feet).  While exterior injections are hardly noticeable, this is not true for interior injections.  When interior injections are being done, the contents of a home must be removed because the chemicals do stain and can splatter during injection.
