GeoSpray® 72″ Brick Sewer Rehab In Washington D.C.

DC Water’s engineering group implemented a pipe entry inspection after receiving an alert from the District Department of Transportation (DDOT) to verify the integrity of a 72” diameter brick sewer. This was located at the F Street NW block between 11th and 12th streets. DDOT had done a bore-hole inspection at a street depression, which revealed a 20-inch deep void under the pavement.
