Question: We have recently went in and redone our warning tracks. The sod cutter has left some good size lips in spots that are going to require some fill. What is the most cost effective material to place in there? The fields drain through the warning track so I am looking for something a little course to keep from washing.

Answer:

Pennington Seed: I would go with MVP from Turface. If they would like to call me I can do a site visit too, if they would like. Amy Mathews, Pennington Seed, Inc. 479-466-4983, amathews@penningtonseed.com

UofA: I’d assume they could use whatever material composes the warning track as fill. If that’s too expensive, a pea gravel of similar sized particles could be used as fill, which would drain well, and then the track material could be placed over the gravel. I would be concerned with gravel coming to the surface it is not buried by a few inches of the track material. I suggest you contact some sports turf managers and get their opinion on this.

Russellville: We used sb2 gravel compacted. It works really well.

JACOBS: Clay mix with infield conditioner should be heavy enough to keep it from washing out provided you have 1.5% grade on fields or less.

DeQueen: Turface is the best material that I have used for this kind of drainage.
