Taken on its own, crawl Space Drainage and Sump Pump Installation treats one part of the problem. Taken in order, it is the part that makes the rest hold. That is how we schedule it on Wallace jobs.
Water keeps coming back, so it needs somewhere to go rather than somewhere to sit.
Drainage and sump pump on midlands and sandhills ground
Around Wallace the water comes in bursts, so capacity matters less than interception and discharge. Getting roof water and surface runoff away from the foundation often removes most of the problem before a pump is specified at all.
Midlands ground drains unevenly. Sand moves water quickly until it meets something that does not, and it then travels sideways — which is why exterior grading gets looked at on Wallace jobs alongside the crawl space.

Why it is worth dealing with now
Nothing about a damp Wallace crawl space improves on its own. The space is enclosed, shaded and over soil — all three work against it drying out.
The full method and the step-by-step for this work is on the Crawl Space Drainage and Sump Pump Installation page, and how it behaves across the state is on the Drainage and sump pump in South Carolina page.
Drainage and sump pump in Wallace: common questions
Where does the discharge go on a Wallace 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.
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 Wallace, it cannot.
What should I have ready when I call about my Wallace home?
Your street in Wallace, when you first noticed it, and what you can see or smell — standing water, a waterline on the piers, insulation hanging down, or a floor that has gone soft. Photographs help.
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 Wallace property changes that.
Will my Wallace crawl space dry out if I open the vents?
Usually not. For much of the year the air around Wallace is warmer and wetter than the crawl space, so opening it up deposits moisture on the cool joists instead of carrying it away.
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.
