Profile: Evergreen Basement Systems is specialized in basement waterproofing, crawl space, sump pump installation, and foundation repair services. The sump pump is the heart of any good basement waterproofing system. As the core mechanism that removes water from the basement, the sump pump is an essential part of most basement waterproofing, or crawl space waterproofing systems. The purpose of the sump pump is to sit in a hole in the basement floor (known as the sump pit), and collect water as it seeps in from the ground, and/or is directed to it from a perimeter French drain system installed around the edges of the basement floor. We also offer sump pump liner, sump lid, sump pump alarm, pump stand, sump pump check valve, floor drain in the lid, and cast iron Zoeller sump pump. We also recommend installing a crawl space dehumidifier into the space. An energy-efficient and self-draining crawl space dehumidifier can remove humidity from the space, and dry wet materials in the area, helping to reduce rot.
