Job Stories From Merlin, OR
Commercial Building Protected from Further Water Damage by WaterGuard

    Bruce P owns a company in Merlin, OR that was starting to have water leak into the basement. He knew that this would eventually cause a big problem if they did not get it fixed shortly. While at a local home show he saw a booth set up for TerraFirma Foundation Systems. He signed up to have them call him and set an appointment.

    The office contacted him a short while later and set up a time for Patrick Dunn to go to his home. Patrick looked around the whole basement to determine the best products to use. He recommended that a TripleSafe Sump Pump be installed, which is equipped with two sump pumps and a battery back up sump pump to drain water out of the basement during even the heaviest rains. Also he recommended that the WaterGuard system be installed. This system is a channel that is installed along the perimeter of the basement and catches water and drains it to the sump pump, preventing water from entering the basement through the foundation. The last product he recommended was the CleanSpace vapor barrier for the crawlspace. This vapor barrier would prevent moisture from coming through the walls and would also direct it to the WaterGuard system.

    Bruce can now run his business with peace of mind that there is no water leaking into the basement.
