When building an artificial football pitch, purchasing turf is only part of the process. The correct accessories—and accurate calculation of their quantities—are critical for performance, safety, and cost control. Below is a clear guide to the main materials required during installation, along with practical formulas for estimating the right amount. A 400 m² field is used at the end as an example.

1. Black Rubber Granules (SBR) or EPDM Granules

These infills provide shock absorption, stability, and proper ball bounce.

Recommended application rates:

• Black granules (SBR): 6–8 kg/m²

• EPDM green granules: 4–5 kg/m²

How to calculate:

Total infill (kg) = Field area (m²) × Recommended kg/m²

2. Two-Component Turf Adhesive

Most adhesives supplied from China are PU two-component adhesives designed specifically for turf installation.

Recommended formula:

Required buckets ≈ (Field area × 0.165) ÷ 10

Round up to the nearest whole bucket to avoid shortage.

3. Jointing Tape

Jointing tape is used beneath seams to bond turf strips together.

The quantity depends on the turf roll layout and the number of seams.

How to calculate:

1. Determine the roll width (e.g., 2 m or 4 m).

2. Calculate how many turf strips are needed:

   Strips = Ceiling(Field width ÷ Roll width)
   

3. Calculate the number of seams:

   Seams = Strips – 1
   

4. Total length of jointing tape:

   Seam length = Seams × Field length
   

Add 10–15% extra for installation tolerance.

4. Silica (Quartz) Sand

Silica sand adds weight, stability, and keeps the turf fibers upright.

Important note:
Due to export restrictions and high freight costs, silica sand is generally not exported and should be purchased locally.

Typical dosage:

• 20–25 kg/m² (depending on pile height and field requirements)

How to calculate:

Total sand (kg) = Field area (m²) × Recommended kg/m²

Example Calculation for a 400 m² Field

Below is a demonstration of how these formulas work in practice.

1. Infill

• Black granules:
  400 × 6–8 kg = 2,400–3,200 kg

• EPDM granules (if used):
  400 × 4–5 kg = 1,600–2,000 kg

2. Adhesive

400 × 0.165 ÷ 10 = 6.6 buckets
→ Round up to 7 buckets

3. Jointing Tape

Varies by layout. A small 400 m² field typically requires 80–120 meters, but should always be calculated based on roll width and seam arrangement.

4. Silica Sand

400 × 20–25 kg = 8,000–10,000 kg
(Procure locally due to export restrictions)

Conclusion

Understanding which accessories are required—and how to calculate them—helps avoid both material shortages and unnecessary overspending. By applying the formulas above, installers and buyers can estimate quantities accurately, regardless of the field size. The 400 m² example demonstrates the process, but the same method applies to any project.
