Acworth
Rolling lots, lake slopes and erosion
Acworth has a lot of rolling ground between Lake Acworth and Lake Allatoona. On sloped lake and subdivision lots, bare red clay washes out quickly, so walls and drainage usually go in together to hold soil and steer runoff.
Erosion control walls
Low block or boulder walls that stop clay from washing across patios, driveways and lawns.
Boulder and stone walls
Natural looking walls for terraced beds on sloped lots.
Drainage behind walls
Gravel backfill, filter fabric and a drain pipe so walls on wet slopes stay put.
