Knight Division TacticalDoes KDT provide sandbags and flood barriers?
Sandbags & Flood Barriers
Yes.
KDT provides sandbags and flood barriers, including filled or empty sandbags, sandbag filling, bulk bags, water-filled tubes and modular flood barriers, delivered and placed by our crews ahead of rising water.
Typical configuration
- Sandbag
- Woven polypropylene, about 14 × 26 in, about 35–40 lb filled
- Planning figure
- About 600 bags for a wall 1 ft high and 100 ft long (common rule)
- Filling
- By hand, or with sandbag filling machines for high volume
- Bulk bags
- About 1–2 ton bags placed with a loader or telehandler
- Water-filled barriers
- Typically about 1–4 ft high, filled on site
- Modular barriers
- Interlocking reusable sections in set lengths
When water is coming, the job is to keep it out of buildings, critical facilities and low streets for long enough. Sandbags are the standard: woven polypropylene bags filled about half to two-thirds full, laid in staggered courses and tamped down so they seal. They're flexible and work almost anywhere, but they take a lot of labor and sand.
For longer runs or faster setup, other barriers fit better. Water-filled tubes are laid flat, then filled with on-site water to form a wall. Modular barriers lock together in sections and can be reused. Bulk bags filled with sand or gravel by a loader build height quickly along levees and roadways.
KDT brings the bags, the sand, filling equipment and the crews to place them, or the barrier system that fits the site. After the water goes down we remove them, and wet sandbags that may be contaminated go into the debris stream.

Questions, answered.
Does KDT provide sandbags and flood barriers?
Yes. We supply empty or filled sandbags, sand, filling equipment, bulk bags, water-filled tubes and modular barriers, and our crews place them.
How many sandbags do I need?
A common rule of thumb is about 600 bags for a wall one foot high and 100 feet long. Higher walls need a wider base and many more bags. Give us the length and height and we'll work it out.
Are water-filled barriers better than sandbags?
For long, straight runs on firm, level ground, water-filled and modular barriers go up faster with fewer people. Sandbags fit irregular ground, doorways and gaps better. Many jobs use both.
What happens to sandbags after a flood?
Sandbags that sat in floodwater may be contaminated and are usually disposed of with flood debris rather than reused. We remove them as part of the job.
