Frequently Asked Questions
What do you use to seal a concrete septic tank?
Sealant rope is recommended to seal the adapter ring to concrete, plastic and fibreglass septic tanks. This will help prevent backflow and subsequent water contamination.
Is a septic tank necessary?
Septic tanks are ideal for properties that aren’t connected to the main sewage pipes provided by local governments or private corporations. They reduce health risks from water contamination and flood damage.
