On a Hamer job, crawl Space Vapor Barrier Installation follows from the inspection rather than preceding it — there is no point specifying this work before the source of the water is known.
Bare soil under the house is evaporating moisture into the space every day.
Vapor barrier on midlands and sandhills ground
Around Hamer the soil dries at the surface and stays damp below, which makes a bare crawl space floor deceptive: it can look dry while still feeding moisture upward. Sealing the ground is what stops that, and the seams and pier wraps are what make the sealing real.
Humidity does the slow damage here. A Hamer crawl space can be dry in winter and damp by late summer without anything having failed, which is why this work is paired with humidity control rather than ventilation.

What is included on a typical Hamer property:
- Clearing and preparation of the crawl space floor
- Reinforced polyethylene barrier across the full soil area
- Overlapped and sealed seams
- Barrier carried up and sealed to walls and piers
Why it is worth dealing with now
Waiting is the expensive option here. Moisture that has been under a Hamer floor for a year has already changed what the repair involves.

Vapor barrier in Hamer: common questions
Barrier or full encapsulation for a Hamer home?
A barrier covers the ground and stops soil moisture. Encapsulation seals the walls and vents too and controls humidity directly. Which one your Dillon County property needs should follow a humidity reading, not a preference.
Will a barrier stop water that is already getting in?
No. A barrier manages soil moisture and vapor, not liquid water under pressure. If water is entering the space near Dixon Pond, drainage comes first or the sheeting simply floats on it.
How do I know whether it is groundwater or a leak?
That is the first thing we establish on a Hamer 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.
How quickly does water under a Hamer 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 Dillon County that window is shorter in summer than in winter, because the space stays warm and humid.
Why does my Hamer crawl space only flood after heavy rain?
That points to surface water rather than groundwater. Storms around Dillon County deliver a lot of water quickly, and when the ground cannot take it fast enough it travels across the surface and in through the foundation vents.
Should the crawl space vents be closed?
It depends on your climate. In humid regions, open vents often bring in air that is wetter than the crawl space, which deposits moisture on cool surfaces instead of removing it — so sealing vents and controlling humidity mechanically usually performs better. In drier climates venting can work. This should follow readings, not a rule.
