I have been living in my house for 35 years and had water in the basement twice, both times during a Noreaster that dropped 12 to 15 in" of rain in 1 to 2 days. Otherwise my basement has been dry. Now all of a sudden I and a neighbor have problems with 2 to 3 in" rain storms and have water in the basement all the time because of what our town highway dept. did. They regraded our road and put up berms along the road bed on the downslope side (across) to prevent run off into peoples yards. The long asphalt road along its length slopes down towards my house and now, because of the berms, works as a perfect super drain draining enourmous quantities of water into my driveway and the front of mine and my neighbor's property with even minor rainfall. My neighbor is further down from me and there is a drain in the road right at his driveway. Even though the drain works, large lakes of water press in on the dirt in our front yards (which did not receive a berm) for the duration of the storm, which can last days, and that water has now artificially raised the water table even though our homes are on a slight hill. The water table is now high enough so that I get inches of water and my neighbor to his knees in the basement. Both of our homes were dry before this. It is extremely aggravating. I contacted the highway dept. and they will put berms at the front of our property and possibly another drain when the wheather gets warmer. However, I want to be safe and have been looking around for a basement waterproofing method.
I have learned that most popular measures, for example the B-Dry system, are very expensive ($10K for a half basement) and rely on diverting water. So I became interested in the claims made by Sani-Tred and specifically have been following the discussion in this forum with interest. My impression from my research is as follows.
First of all, my congratulations to Sani-Tred for the civility they showed in this discussion when they were being attacked in a nearly vulgar manner by waterproofing interests to whom they seem to represent a serious threat.
As a trained engineer/scientist I reviewed all the claims made by Sani-Tred on their web site and the testimonials given. I have found that they are apparently the only people capable of giving a scientifically correct answer about groundwater properties with regard to hydrostatic pressure and the behavior of groundwater around a home in general. If the material Sani-Tred advertises indeed works as they suggest then it is a foregone conclusion that hydrostatic pressure problems have been solved. That is, by virtue of a flexible, penetrating sealant that has the capability to seal micro and macro pores and even cracks, has memory effect for expansion/contraction and is chemically inert. They are the only site that correctly and honestly states facts about hydrostatic pressure and doesn't use that term to scare people. The pressure is clearly calculated to be minimal in a basement and a material with the properties as claimed by Sani-Tred would have no difficulty dealing with it. That's a done deal!
My own course of action will probably be to follow someone elses suggestion made on this forum, which is to order a small quantity and simply test it out on the most severe spots in my basement. If Sani-Tred's claims are correct I should see an immediate and significant improvement. Regardless, I will report back and, if results are positive, then proceed with a more extensive application. Actually, I love the fact that I can apply this material in stages at my disgression and time and fully under my own control and at much better cost. Much better than spending $10K right off the bat and not knowing what you might get.
I am a private individual, not influenced by Sani-Tred or anyone else in any fashion, just looking for some honest, competent, and correct answers to this problem. I found the answers provided by Sani-Tred in this forum to be far more convincing and competent then the ones offered by the typical waterproofing interests.
