What crawl Space Drainage and Sump Pump Installation involves in Coosawhatchie is the same as anywhere. What differs is the condition it is dealing with, and that is set by the ground the house sits on.
Water keeps coming back, so it needs somewhere to go rather than somewhere to sit.
Drainage and sump pump on lowcountry and coastal plain ground
Near Coosawhatchie a sump is often working against a standing water level rather than an occasional event, and close to the coast that level can be tidally influenced. The system has to be sized for water that keeps arriving, and the discharge has to go far enough that it does not simply return.
In Coosawhatchie the complication is the water table. It sits close enough to the surface that soil under a house can be saturated with nothing broken, so this work is usually dealing with moisture arriving from below rather than from a failure inside the house.

Drainage and sump pump in Coosawhatchie: common questions
Can grading fix it without installing a pump?
Sometimes, and it is checked first because exterior water is the cheapest to deal with. Where the water table itself rises into the space, as it can around Coosawhatchie, it cannot.
Does a sump pump need a backup here?
Worth considering if your Coosawhatchie crawl space takes water during storms, because storms are when the power fails — which is exactly when the pump is needed.
Why is my Coosawhatchie crawl space wet when nothing has leaked?
Near Coosawhatchie that is the normal pattern rather than the exception. At around 10 feet on the coastal plain, the water table sits close enough to the surface that soil under the house can be saturated with no pipe broken.
Can I stay in the house while the work is done?
In almost all cases, yes. The work happens under the floor, and access is usually through an exterior hatch. We will tell you up front if anything about your Coosawhatchie property changes that.
How do I know whether it is groundwater or a leak?
That is the first thing we establish on a Coosawhatchie call, because everything after it depends on the answer. A supply line, a drain, water rising through the soil and runoff coming in through the vents each leave different evidence.
Do I need drainage, or will a vapor barrier be enough?
A barrier handles soil moisture and vapor. If liquid water is entering the space — after rain, or as the water table rises — it needs drainage and a sump as well, because a barrier laid over water simply floats on it.
