Key Factors for Compliance

1. Stability and Firmness

1.  

• The surface needs to be solid and supportive, so mobility devices don’t sink or get stuck. 
• A well-compacted base and evenly applied infill help maintain stability over time.

2. Pile Height and Infill Choices

2.  

• Shorter pile heights (typically 1.25 inches or less) make it easier to move across the surface. 

• Infills, such as sand or coated rubber granules, should be evenly spread to prevent uneven areas. 
• If infill is too loose or deep, it can make movement difficult.

3. Smooth Transitions and Edging

3.  

• ADA guidelines require minimal changes in height (less than 1/4 inch without a beveled edge or up to 1/2 inch with a beveled edge) to allow for smooth movement. 
• Proper edging helps connect artificial grass seamlessly to surrounding surfaces like concrete, rubber tiles, or pathways. 

4. Impact Protection with ASTM F1292

• While ASTM F1951 ensures accessibility, ASTM F1292 deals with impact protection and is mostly about shock pads or underlayment, not the turf itself. 
• To meet ASTM F1292, artificial grass installations may need extra padding beneath the surface to absorb falls and reduce injury risks.

5. Drainage and Maintenance

5.  

• Good drainage keeps the surface firm and prevents hazards like pooling water. 
• Regular upkeep, such as infill replacement and leveling, helps maintain compliance over time.
