What is a shock
A shock treatment is an
ecological and simple way to
clean a septic system.

This shock treatment includes:

4 liters of SeptiDrain $114.00+taxes
1 bag of SeptiMax $89.95+taxes
total: $114 + $89.95 - $50 (discount) = $153.95+taxes

Moderate shock treatment

This shock treatment is intended for those who are beginning to
see problems
with their septic system.
For example: if the ground becomes abnormally wet or if the water level in the septic tank seems abnormally high.

This shock treatment includes:

10 liters of SeptiDrain $239.00+taxes
2 bags of SeptiMax $179.90+taxes
total: $239 + $179.90 - $100 (discount) = $318.90+taxes

Intensive shock treatment

This shock treatment is for those who have a major septic
system problem
and want to solve it as quickly as possible.
For example: if the septic tank overflows or if there is literally a pool of
water above the leaching bed.

This shock treatment includes:

20 liters of SeptiDrain $419.00+taxes
2 bags of SeptiMax $179.90+taxes

“Much easier for me to do the grass, because it's not soaking wet anymore. Now I can walk on it without having my feet in the water. The water runs off much easier without blocking the toilet or sink. Thank you very much for taking a weight off my shoulders.”
Danny Bélanger
from Saint-Jacques
“"In the fall of 2015, my septic tank overflows, I have my tank emptied for the first time. A few days later, same problem. This time, I call the plumber to identify the problem. I had the tank emptied a second time, the plumber put his camera on and diagnosed that the leaching bed was clogged. Cost for the plumber and the two drains: close to $3,000. Recommendation: redo the field. The costs will be astronomical considering my pension income. After discussion with a brother-in-law, he tells me that he used Bio-sol products and that it saved his septic tank and septic field. I have nothing to lose. I contact the Bio-sol representatives, explain my problem to them and they give me their recommendations. A few days later, I receive their products, I follow the recipe and in less than a week, everything is back to normal. For a few hundred dollars, I saved several thousand. Thank you, to the people at Bio-sol.”
Claude Trudel
from Pointe-Lebel
“I discovered the world of septic tanks when we bought our little cottage in 2013. Smells. An emptying to be done regularly. I haven't had to empty it in three years! After a lot of research on the internet, I discovered Bio-Sol, its products and especially Mr. Gagné's experience and valuable advice. I learned how to take care of the pit, feed it well, don't put anything in it. I haven't had to empty it in three years! I recommend without hesitation!”
Hélène Francoeur
from Saint-Fabien-sur-Mer
“I have been using the products for several years now and no more gurgling into the sink and water that comes back into the tank. My leaching bed is working better and if not, I do shock treatments if necessary!”
Mélanie Lévesque
who lives in St-Léon-le-Grand
“In the fall of 2017, we hired a plumber for a sewer backup in the basement. Two months later, the same problem arose, we had the plumber come back, who showed us on camera that the entrance to the septic tank was blocked and, since it was winter, that we would have to have the snow removed to reach the tank, clear the entrance and have it drained, all at very high cost, not to mention the unexpected surprises. Fortunately, a neighbour told us about a pamphlet from Bio-Sol that he had received in the mail. We visited the site on the Internet and immediately contacted the company. After speaking with Mr. Gagné, who gave us clear explanations and valuable advice, we ordered the products, which arrived a few days later. Since then, our septic tank has been working perfectly, no more backflow, no more unpleasant odours. Mr. Gagné also advised us on products to use such as toilet paper and detergent to keep our septic tank in good condition. We are completely satisfied with Bio-Sol products and we strongly recommend them. Thank you very much!”
Robert Bois
from Rimouski
“I've been using Bio-Sol products for three years. For my part, it was a preventive treatment because I had no problem with my septic field. I will therefore testify to the service I received. I was well received by a staff that knows its products well. People are smiling and welcoming. I enjoyed doing business with them.”
France Bélanger
from Magog
“As soon as we tested the bio-sol products, the results were conclusive, no more backflow from the tank, so the leaching bed has been working very well since then. I recommend it to everyone who has a house in the township or country, it's a good way to extend the life of your installation.”
S. Fiset
from Granby
“I have been using Bio sol for a few years now and I am very satisfied that my leaching bed has no more smell. I recommend to all those who have a septic system to use Bio Sol, a very responsible and reliable company.”
Agathe Proulx
from Ste-Anne-des-Lacs
“30 year old leaching bed. The water level in the pit was high. I had two choices, to redo it or to treat it with BIOSOL. Total success after one year of treatment. Bed is working well and the sludge test is normal. Very satisfied with a very good service.”
