Efflorescence
- Efflorescence: This condition produces a white or sometimes grayish ash on the walls. Sometimes it sparkles. Efflorescence is caused by salt deposits left behind by evaporating water.

Basement Waterproofing Information 
Foundation waterproofing starts when the concrete foundation is poured. A rubberized spray can be applied to the exterior of the foundation to form a waterproof barrier. Secondly, if there are any cracks in the foundation a polyurethane foam can be injected using a low pressure system. Lastly, a sump pump should be installed in the event a crack opens up while the water table is high.
The major components of basement waterproofing are sump pump installation, drainage systems and foundation crack repair if there is existing damage. Once these elements are in good shape the homeowner should seriously consider finishing the basement as there’s a return on investment monetarily and it increases living quality.
