MISSILING IS MOST COMMONLY USED ON LONG ISLAND FOR UNDERGROUND INSTALLATION OF UTILITIES, SUCH AS :
WATER LINES, ELECTRIC LINES, COMMUNICATION LINES, IRRIGATION (SPRINKLER) LINES ARE ALL INSTALLED BY THIS METHOD.
A SUBTERRANEAN MISSILE IS A LONG CYLINDER WITH A POINT AT ONE END AND AN AIR HOSE AT THE OTHER END. IT'S NAME IS DERIVED FROM IT'S RESEMBLANCE IN SHAPE TO A MISSILE. MISSILES VARY IN SIZE AND DIAMETER. SOME OF THE MOST COMMON DIAMETERS ARE 2 1/2",3" ,AND 4",DEPENDING ON THE SIZE OF THE PIPE OR WIRE TO BE INSTALLED.
THE MISSILE IS A PNEUMATIC TOOL,DRIVEN BY AIR PRESSURE. THE AIR IS USUALLY GENERATED BY A GAS OR DIESEL ENGINE ON A TOW BEHIND OR STATIONARY MOUNTED UNIT THAT CONNECTS TO THE MISSILE WITH A 3/4" AIR HOSE.
THE MOST COMMON DISTANCE THAT IS RECOMMENDED FOR MISSILE USE BETWEEN EXCAVATION HOLES IS 50'. BUT IN GOOD SOIL CONDITIONS WE HAVE MADE UP TO 90 FOOT " SHOTS ". SOME SOIL CONDITIONS ON LONG ISLAND CAN MAKE MISSILING ALMOST IF NOT ALTOGETHER IMPOSSIBLE; SUCH AS LARGE BOULDERS UNDERGROUND.
THE GREATER PERCENTAGE OF THE TIME A MISSILE WILL PERFORM AS EXPECTED.
FOR UNDER DRIVEWAYS, PARKING AREAS, FINISHED LANDSCAPING OR PATIOS, MISSILING CAN SAVE MONEY ON RESTORATION COSTS.
ANOTHER APPLICATION OF THE MISSILE TOOL IS "PIPE JACKING ". PIPE JACKING INVOLVES PUSHING A STEEL PIPE UNDER THE GROUND TO USE AS PART OF THE SYSTEM FOR NEW PIPING OR JUST AS A SLEEVE FOR MULTIPLY WIRES OR PIPES.
WE HAD ONE CUSTOMER WHO NEEDED TO MOVE HIS SEWER LINE. UNFORTUNATELY HE HAD JUST COMPLETED A 25' DECK OVER THE AREA WHERE THE PIPE WOULD HAVE TO RUN TO CONNECT TO THE NEW CESSPOOL SYSTEM WE WERE INSTALLING. WE WERE ABLE TO PIPE JACK A 4" Galvanized STEEL LINE UNDER THE DECK AND INTO HIS BASEMENT TO CONNECT TO THE NEW PLUMBING. WE FIGURED THE PIPE JACKING TO BE THE MOST ECONOMICAL WAY TO GET THE SEWER LINE TO WHERE IT NEEDED TO BE AS OPPOSED TO BREAKING UP THE DECK.
IF AIR MISSILING OR PIPE JACKING SEEMS LIKE A SERVICE YOU COULD USE ON YOUR PROJECT- GIVE US A CALL.

| 2" WET TAP ON A 4" WATER MAIN |
|

 |
| 4" WET TAP ON 6" WATERMAIN |
|
|
A "WET TAP" IS ESSENTIALLY MAKING A CONNECTION ON A LIVE WATER MAIN WITHOUT HAVING TO SHUT DOWN THE WATER MAIN. DIFFERENT METHODS ARE USED TO MAKE THIS CONNECTION. SOME "TAPPING MACHINES" WILL DRILL AND THREAD A "CORPORATION STOP"-(SHUT-OFF VALUE) DIRECTLY INTO THE WATER MAIN. OTHER TAPPING MACHINES WILL USE A SADDLE THAT IS BOLTED TO THE WATER MAIN AND DRILL THROUGH THAT AND THREAD THE CORPORATION STOP INTO THE SADDLE.
NOT EVERY WATER DISTRICT REQUIRES THE CONTRACTOR TO PROVIDE A WET TAP. SUFFOLK COUNTY WATER AUTHORITY PERFORMS THEIR OWN WET TAPS. IF THE WATER MAIN IS PRIVATELY OWNED THAN IT WOULD BE THE OWNERS RESPONSIBILITY TO ARRANGE FOR THIS SERVICE. WE HAVE ON OTHER OCCASIONS PROVIDED A WET TAP FOR A NEW SERVICE, BECAUSE THAT PARTICULAR WATER DISTRICT DIDN'T PERFORM THIS WORK. OTHER PLACES WHERE A PRIVATE CONTRACTOR WOULD BE NEEDED TO PROVIDE A WET TAP MIGHT BE: PRIVATE COMMUNITIES, INSTITUTIONS (SCHOOLS, COLLEGES) ,HOSPITALS OR ANY LARGE COMPLEX.
