I used BaseTech for both waterproofing and landscaping. I had a couple of basement leaks a few years back and they fixed the leaks and have had no issues since. Their work was impeccable.
I also just did a big landscaping job in my backyard and all I have to say is wow - these guys are top notch. They pay attention to detail, educate, are fair in pricing and do outstanding work.
I highly recommend them!
