Drill and Fill is accepted world - wide as the proven method to
modify the root zone without total renovation and while keeping the turf in
play. Whether the problem is compaction and poor drainage or
accumulated layering, the result of Drill and Fill aerification is improved turf
quality. This process drills holes up to 12 - inches deep into turf on 6 - inch
centers, removing soil and backfilling each hole with sand to create deep
sand columns in the root zone profile. Drill aerification without fill is an
alternative process effective in reducing “ iron layer ” problems and
greatly improves drainage.
