Water comes onto our property when there are heavy rains and a pool of water collects around a tree around the middle of the lot. Someone said legal action against the property owner will fail and another person, the tenant in the house next door to the vacant lot which is also owned by the property owner of the vacant lot said the water drainage problem is controlled by God. The property owner has allowed this to get worse over the years due to zero maintenance. It needs a dump truck load of dirt maybe two loads. So one idea was to build a retaining wall using railroad ties stacked only 2 deep. One with half of the tie under ground and a top tie that would be attached in some way to prevent water getting through. What ways are there to adhere ties so they are water leak proof and well as the legal aspects. Thanks.
Update: Apparently no one read the question. We desire to build a retaining wall on our property to prevent water from someone else's vacant lot from flooding our yard. What adhesive can we use with railroad ties so water does not seep through the cracks. Thanks.
