Karim has worked as an account manager in the industry of security. He was mainly advising customers through the process of selecting which alarm system or surveillance system, based on theirs needs. Karim is a person who wants the best for his clients and he wants to answer the customer expectations.  

Systèmes Sous-sol Québec took into consideration Karim's assets and what he could add to the company in terms of experience in customer-service and sales-consulting and subsequently decided to get him on board. By sharing his experience with homeowners and explaining the effects of water or foundation damage, he can really relate to them and prevent problems before they occur or worsen. He is a trusted and valued member of the Systèmes Sous-sol Québec team and upholds the standards of the company. Karim has been thoroughly trained and has earned the title of “Waterproofing and Foundation Repair Professional” through the Basement Systems and Supportworks international networks.

Systèmes Sous-sol Québec is also the dealer of Supportworks Inc., a foundation repair contractor network across the United States and Canada, helping residential and commercial property owners fix their failing foundations.

Karim believes in the fact that he needs to be an educator and not a salesman. He likes to be along with the customer during all the process and he likes to answer the client's questions. 

He is passionate about photography, it is his favorite hobby during his free time.

    Ms. Lauzon had a problem with water infiltration in a room in her basement. Wall efflorescence means that there is water and moisture seeping into the walls and this causes a white powdery substance (mineral salts) to appear on the concrete walls. .


    The solution

    Install a sump pump system as well as a WaterGuard interior drain. First, a hole was dug to install our SuperSump sump pump system. It features a powerful ⅓ HP Zoeller cast iron sump pump capable of pumping 8,300 gallons of water per hour out of your basement to a height of 8 feet. Then a trench is dug all along the foundation walls to reach the foundation footing and the WaterGuard is laid in it. It collects water from the walls and the floor.


    With this solution, Ms. Lauzon now has a permanently dry basement.

    Mr Achachi had moisture problems in his basement. He could see in some places of his basement walls traces of water and this meant that there was water seeping through the foundation walls in his basement.

    One of the causes was the presence of cracks in the foundation walls that allowed water and moisture to seep into the basement.


    We first sealed these cracks with our FlexiSpan solution. Next, we installed a SuperSump sump pump system which includes a 1 / 2HP cast iron Zoeller pump. This way the soil water is drained outside away from the house and it can reduce the humidity in the basement. And then a WaterGuard foundation interior drain was laid on the foundation footing. This collects the water coming from the walls and which may be on the surface of the ground to direct it towards the SuperSump to evacuate it.
