I wish to recommend Mark at AquaDry Technologies in the strongest of terms! After speaking with representatives of several other companies that repair leaky basements, he was the only one to properly identify the source of our leaks and offer a permanent solution -- at one-tenth of the cost of what others had suggested.
After discovering that one of the walls in our basement had started weeping rain water causing significant flooding, we called in several companies to look at it and offer their recommendations and estimates. They all said that it would require excavating the outside of the wall down to the footing and installing a barrier membrane. The effort would require several days or weeks of work at a cost of $8 - 12k, plus the additional need to redo our landscaping on that side of the house.
Mark, on the other hand, took the time to seek out the root cause of the leaks. He showed us that the water was coming in from two cracks in the wall and several old tie-rod holes that were hidden behind the insulation. Using his polyurethane injection process, he was able to repair both cracks and all of the tie-rod holes for roughly $1,000. The repair had immediate effect, and was minimally invasive to our property -- I would liken Mark's solution to laser surgery versus the competitors' suggested hack job!
It has now been several weeks since Mark repaired the wall and the leaks remain completely sealed. Our basement is dry and I am confident that with AcquaDry's 25 year warranty and the strong record that polyurethane injection crack repair has demonstrated (google it if you like), we will not face any further leakage from these cracks or tie-rod holes.
If my friends and neighbours face basement leak problems in the future, Mark at AcquaDry Technologies will be the person that I tell them to call!
