It's warm outside and people are watering their lawns on a regular basis. Can a rigorous watering cycle cause water in the basement? Well, sometimes it doesn't even have to be rigorous. We have already gotten a couple of calls, one from Dedham and one from Shrewsbury, where people are turning on their irrigation systems, it hadn't rained, and people are calling and saying they have water coming in the basement.
There are pre-existing conditions. One was a crack in the poured concrete foundation and water was coming in through that. The other was a leak around the sewer pipe, between the sewer pipe and the concrete, and water was coming in through that. One home had the sprinkler going up against the crack anc the other there was a line that was broken in the soil and the water was coming in around the sewer pipe.
So to answer the question, these sprinkler systems can help you to identify where water is coming in through a basement. One of the first things I asked people who have water coming in the basement when it is dry out is if they have a sprinkler system.
To fix the problem, if it is a crack in the foundation we can do all the work from the inside. Or, a leak in the sewer pipe, we'll drill into the foundation at angles and put ports into the small holes we drill and fill it with closed polymer resin. Or, we will put another material in the crack and then a weave carbon fiber blanket on top of that. Then we can give them a written warrantly against water coming in the basement.
