Although interior water drainage is not technically waterproofing ,
it is a widely accepted technique in mitigating basement water and is generally referred to as a basement waterproofing solution.There
are a number of situations that may determine if an interior drainage system is the solution best suited to your
particular needs . Firstly , if your leak is caused by hydrostatic pressure forcing water up from under the basement floor
slab , no amount of digging on the outside will solve the problem , you must install an inside drainage system to
control this water . There are situations where the leaks are coming through the foundation but an exterior repair is impractical
or impossible due to obstructions or elaborate landscapes . Lastly if budget is a concern an interior drainage system is generally
40-50% cheaper than an exterior repair .
