What this job is
Depths: 24 inch for many HOA parkways, 30–36 for walks with a serious plate, deeper for foundation and lateral work. Thickness goes up on commercial islands.
Joints are where cheap jobs fail. Roots thread a gap the width of a credit card. We lap or lock every joint.
Bamboo gets a lip above grade. Sidewalk jobs sit slightly below mower height so the HOA does not call it a trip.
Problems that actually show up
- A recycled sheet that went brittle in Gulf sun
- Joints that roots threaded
- A 12-inch edging sold as barrier
- Need for 24 / 30 / 36 inch panels
- Commercial thickness on a parking island
- A lip detail for bamboo
Sequence
- Spec Depth, thickness, length, lip or no lip.
- Material on the truck We stock the common Houston sizes.
- Set to the floor A panel hanging in a void is not a barrier.
- Join and backfill No gaps, no voids against the face.
