How Many Wire Snake Spacers Do I Need?
Wire snake spacers are 2 m long continuous supports. They work differently to point spacers - you lay them in parallel lines under the mesh rather than placing individual chairs. Here is how to work out how many you need:
Quick guide per mesh sheet
| Mesh Sheet Size |
Recommended Snake Spacers |
Spacing Between Snakes |
| 3.6 m x 2.0 m (standard merchant mesh) |
5 snakes per sheet |
Approx 600-800 mm centres |
| Heavy duty / industrial slab (forklifts, racking) |
Increase to 6-8 per sheet |
Reduce to 400-600 mm centres |
| Double-layer mesh (top and bottom) |
5 snakes per layer per sheet |
600-800 mm centres per layer |
Calculate by slab area
Each snake spacer is 2 m long. To work out how many you need for a given area:
- Decide on your spacing between snakes: 600 mm for standard slabs, 400-500 mm for heavy duty
- Divide your slab width by the chosen spacing to get the number of lines needed
- Divide your slab length by 2 m (snake length) and round up to get snakes per line
- Multiply lines x snakes per line, then add 10-15% for overlaps and cut pieces
Example: A 10 m x 6 m slab at 600 mm centres = 10 lines of snakes. Each line needs 3 x 2 m snakes (6 m ÷ 2 m). Total = 10 x 3 = 30 snakes. Add 15% = 35 snakes.
Placement tips
- Lay snakes perpendicular to the longest span of the mesh
- Butt snakes end-to-end for continuous lines across the slab - no tying required
- Keep snakes at 600-800 mm centres for standard domestic and commercial slabs
- Reduce to 400-600 mm centres where loads are high (forklifts, racking, heavy plant)
- Add an extra snake at each edge of the slab and at any construction joints
