Aqua Tech had waterproofed my basement exterior last summer 2014. I am renovating the interior basement this year. During interior finished wall teardown I found some dampness had collected at the base of the corner in an area that had been waterproofed from the outside in 2014. Andrew came the same day, inspected the area and felt that this was moisture that had built up over extended period of time prior to the repair in 2014. We tested for water in the block wall by drilling test holes and found nothing. As a courtesy, an Aqua Tech crew came the next day, 'so we could sleep at nights and not worrying about an potential future water damage'. They sealed the inside corner at no cost to us! Great crew, great company - they know their business!
