We will tell you if crawl Space Drainage and Sump Pump Installation is not what your Pinopolis crawl space actually needs. Doing this stage out of order is the most common reason the work has to be repeated.
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 Pinopolis 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 Pinopolis 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.

Why it is worth dealing with now
Waiting is the expensive option here. Moisture that has been under a Pinopolis floor for a year has already changed what the repair involves.

Drainage and sump pump in Pinopolis: 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 Pinopolis, it cannot.
Where does the discharge go on a Pinopolis property?
Far enough from the foundation that the water does not track straight back in, to a point that is legal locally. Discharging beside the wall is the most common fault we find, and it is why some pumps run constantly.
Does being close to the coast make this worse?
It raises the water table and lengthens the wet season, which is why homes near Lake Moultrie and the low ground around Pinopolis tend to need drainage as well as a barrier.
Does storm flooding reach crawl spaces around Pinopolis?
Yes, and often with nothing visibly broken. After a tropical system the usual picture in Berkeley County is a saturated crawl space where the water came up through the ground rather than out of a pipe.
Why is my Pinopolis crawl space wet when nothing has leaked?
Near Pinopolis that is the normal pattern rather than the exception. At around 89 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.
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.
