Rock Bloks is a drywall drainage and ventilation system built for homes and buildings that flood. Walls could dry in days, not months.

The problem
When water enters a wall, drywall sits flush with the floor and seals it in. The cavity stays wet for months. That's where mold, mildew, and the bulk of the repair bill comes from — not the flood itself.
how long a wet wall cavity can take to dry without ventilation.
starts inside the wall long before you can see anything on the outside.
The solution
Rock Bloks install at the base of the wall before the drywall goes on. They lift the drywall off the floor, leaving a path for water to drain back out, and let air into the cavity so the wall can start drying immediately.
Air moves through the wall from the first day. Walls dry in days instead of months.
Walls dry in place instead of being torn out and replaced. Less debris, less downtime.
Skip drywall replacement and mold remediation.
Less trapped moisture, less mold and mildew, less rot inside the wall.
How it works
Frame the wall normally.
Standard studs, base plate, and top plate. Rock Bloks attach to the studs and base plate at the bottom.
Set the drywall on top.
Drywall rests on the Rock Bloks, sitting above the floor instead of flush with the floor.
Water drains out.
After water enters the cavity, it exits through the openings created by the blocks instead of pooling.
Air flows in.
As water leaves, air enters from the same path. The cavity ventilates instead of suffocating.
The wall dries.
Dryout time drops from three to four months down to three to four days in most cases.
Who it's for
Coastal, canal-front, low-lying lots, or anywhere that's flooded before.
Cut drying time on every job and reduce repeat callbacks for mold.
Spec Rock Bloks on new builds and rebuilds in flood-prone regions.
Keep tenants in place instead of gutting walls after every flooding event.
Pair with standard FEMA wet floodproofing for drying the ground floor.
Less invasive repairs lead to smaller payouts and faster claim resolution.
