On a Sardinia job, crawl Space Drainage and Sump Pump Installation follows from the inspection rather than preceding it — there is no point specifying this work before the source of the water is known.
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 Sardinia 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.
Low ground and a long wet season change what this work has to withstand around Sardinia. Homes near Rainbow Lake in particular tend to need the drainage question answered as well, or the space simply returns to how it was.

Included as standard on Sardinia jobs:
- Assessment of water source, arrival points and low spots

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

Drainage and sump pump in Sardinia: common questions
Does a sump pump need a backup here?
Worth considering if your Sardinia crawl space takes water during storms, because storms are when the power fails — which is exactly when the pump is needed.
Where does the discharge go on a Sardinia 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.
Why is my Sardinia crawl space wet when nothing has leaked?
Near Sardinia that is the normal pattern rather than the exception. At around 102 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.
How quickly does water under a Sardinia house need to come out?
Quickly. Wood starts absorbing moisture immediately and mold can establish on damp material within roughly 24 to 48 hours. In Clarendon County that window is shorter in summer than in winter, because the space stays warm and humid.
How do I know whether it is groundwater or a leak?
That is the first thing we establish on a Sardinia 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.
Can grading and gutters fix it without a sump?
Sometimes, and it is always worth checking first, because exterior water is the cheapest to deal with. Where the problem is surface runoff from a roof or a slope, fixing discharge and grade can be enough. Where the water table itself rises into the space, it cannot.
