We have to construct Septic Tank in Basement area along with Parking. In Parking, walls of septic tank is visible and chances of leakage of sewage or liquid and it would be very bad condition so I'm searching for Waterproofing option by which leakage will be stopped.
Best waterproofing option for Septic Tank
- Thread starter Upkar
- Start date
YOU WILL NEED TO DO THE TREATMENTS AS MENTIONED BELOW FOR BEST RESULTS:
First, you have to WATERPROOF THE WALLS AND SLAB INTERNALLY USING THE TRADITIONAL WATERPROOFING TECHNIQUES methodology could be as below:
- GRIND THE SURFACE SO AS REMOVE ALL THE DUST, LAITENCE, DIRT ETC ANY AND ALLOW MATERIALS WHICH COULD CAUSE DEBONDING OF THE WATERPROOF COATING. CLEAN WITH WATER JETTING.
- CONDUCT WATER TEST BY FILLING TANK WITH WATER AND MARK SURFACES OF LEAKAGES.
- GET THE LEAKAGE AREA GROUTED WITH EITHER A CEMENTITIOUS EXPANSIVE GROUT OR A POLYMER CEMENTITIOUS GROUT OR IF BUDGET PERMITS A LOW VISCOSITY GROUT WILL WORK WONDERS.
- AFTER GROUTING IS COMPLETED APPLY A CHEMICAL BASED WATERPROOFING COATING from any of the indigenous manufacturers like KRISHNA CONCHEM OR SUNANDA (POLYALK-WP)
- Apply at least a minimum of 2 coats of POLYALK-WP OR EQUIVALENT COATING. let it air dry for 48 hours with a liberal spraying of water for curing purposes as cement is involved. Please follow the manufacturer's specifications.
- Am also attaching a methodology for all types of waterproofing works as laid down by Sunanda as a ready reference.
IF THERE IS NO LEAKAGE AND FOLLOW THE BELOW TREATMENT:
you need to further GIVE AN EFFLUENT TREATMENT which could be 2-3 coats of COAL TAR BASED HI BUILD EPOXY COATING WHICH WILL WORK AS A ANTICORROSIVE TREATMENT. Selection of right material is important you can use EPCO 2020 TX FROM KRISHA CONCHEM PRODUCTS PVT LTD OR SUNEPOXY COALTAR FROM SUNANDA SPECIALITY COATINGS PVT LTD.
IF THERE IS LEAKAGE THEN DO THE LOCALISED GROUTING WHICH I HAVE MENTIONED ABOVE AND THEN FOLLOWED BY ANTI CORROSIVE COATINGS.
