How To Seal A Septic Tank

Step 2 

The welder then measures the cage’s diagonals to make sure it’s straight. Next, the welder places rebar spacers to hold the cage centered in the frame and leveled on the ground. A crane lowers the cage into a custom formwork made of high-strength steel plates. Then workers close the walls around the form and secure them in place with heavy-duty locks. 

Step 3

The crane lowers machined steel cores to form the interior walls of the tank chambers. A rigid plastic tube is inserted inside a rubber sleeve to create a flow hole between chambers. Using an acetylene torch, a worker cuts holes in the rebar for access openings. The mold allows concrete to flow over the rebar and embeds the access opening covers in the septic tank lid. 

Step 4

For medium-sized septic, tank worker pours over 1300 gallons of wet concrete into the mold. They use a stick vibrator to eliminate air pockets and level the walls with a putty knife. Next, they mix more concrete and pour it over the top slab rebar. Concrete blocks are used to keep the plastic covers from floating in the wet concrete. 

Step 5

Then a worker levels the top of the slab with the trowel. Once the concrete tank has cured, workers strip the forms. They remove the concrete tank using an overhead crane and a compressed air system, which forces the mold away from the concrete tank.

The crane takes the strip core away for cleanup. A worker brushes the top of the walls and sweeps the floor inside the tank. Then he applies a butyl rubber tape around the top of the exterior wall. This is what helps watertight seal between the tank and the lid. 

Step 6

An overhead crane lifts the lid out of the formwork and brings it to the tank mold. The crane slowly lowers the lid onto the tank. Workers keep it align to make sure it seals properly. Then the mold is removed from the finished septic tank. This is how a ready-made septic tank is made and it is ready to be installed under your house.
