Aftercare and maintenance instructions for rubber /sandfilled football pitches
Polytan MegaGrass 2050 ACS
Weekly (and ongoing care) requirements:
FThe sand/rubber infill material must be kept to approx.9-11 mm under the fibre tips and brushed regularly to keep it even.
FThe 6-yard box, penalty spot and corner areas must be kept to approx. 6-8 mm below the fibre tips. These areas are subject to the greatest wear and tear and therefore require greater care and attention.
FThe goal areas must be checked to ensure that the rubber infill is even. The infill material in these areas suffers the most displacement within the artificial turf system in every game or training session. Only if they are permanently infilled do the artificial blades of grass offer optimum protection and therefore a long service life for the football pitch.
FDisplaced infill material must therefore be replaced continuously, which means that the ground staff must have an adequate supply of infill material at all times - ideally this material should be stored near the pitch to ensure that it only has to be carried short distances allowing the staff to react quickly.
FOnly by regular dragging, drag-matting, brushing, for example, can you guarantee that the level of infill material is kept at the prescribed level and that the artificial turf system is perfectly infilled. The infill material protects the carpet!
FPlease note that after every 50-60 hours of use, the pitch must be dragged or drag-matted or brushed. If the pitch is used more frequently it must be drag-matted or brushed more often to maintain its performance characteristics in the long term.
FThe regular drag-matting of the so-called edge zones (for example the outside areas) are also important to ensure that natural grass, moss and weeds do not start to grow there. Plants will only start to grow if you fail to drag-mat certain areas. Any existing vegetation growth must be removed mechanically (tear the plants out, cut them or spray them with high water pressure).
In extreme circumstances weed killer (in the appropriate dilution) may be used for specific areas. To prevent the large scale migration of vegetation into the edge areas, we recommend that you
periodically cut back the vegetation outside the edge zones.
FRemove surface dirt on a regular basis. Remove leaves, twigs, etc. immediately
(use a leaf blower if necessary).
FAfter the initial phase (4-6 months after installation) check the infill level of
the system and redress with new infill where necessary.
FYour budget for the second year should include approx. 2 kg of infill material per square meter of pitch area. “Rubber granulate” infill material is subject to a constant settlement process and will reduce in volume during the course of its use as a result of mechanical influences in the grain size structure. This material must therefore be replaced or renewed.
Wear losses (fine particles) must be removed by thorough cleaning.
We therefore recommend that every other year of use (on the basis of current calculations) you use approx. 2 kg of rubber granulate per square metre.
FThorough cleaning: When the pitch is dry extract the infill material from the turf system using a suitable sweeping and suction machine. The main criterion for this important cleaning work is that the surface of the turf is “open”, so that the brushes in the machine can draw up the infill material.
After the infill material has been picked up, the machine separates out all the fine particles (fibres, rubber, shoe wear and sand) and the remaining infill materials are then brushed back into the turf system.
FSnow removal: Maximum wheel load: 2 tonnes per axle (for systems with an elastic base course). In principle when clearing snow, a layer of approx. 2 – 3 cm of snow should be left, so as to protect the artificial turf from mechanical damage.
The above maximum wheel load refers exclusively to Polytan systems (in other
words those that have an elastic base course). This statement does not apply to
pitches that have a non-bound base course.
The pitch markings (ideally YELLOW in colour) can be cleared using a road-
sweeping brush.
FPartially iced pitch surfaces can be thawed using conventional “winter salt” (please
consult your local department of the environment).
FOther dirt such as sand, topsoil and grass cuttings from neighbouring natural grass
pitches should be removed immediately where necessary using sweeping machines.
This will prevent the artificial turf suffering deep rooted
contamination.
FSharp objects (stones, shards of glass, etc. ) must be removed immediately.
FChewing gum waste can be removed easily after it has been iced with refrigerant spray.
FOil and fuel must be soaked up as quickly as possible using sand or sawdust and then removed in full.
FOther contaminants can be scraped off the surface by shove. Residual animal faeces can be treated with vinegar and water.
Instructions for preventing damage
FFollow the aftercare and maintenance instructions
FOperation of maintenance equipment on the surface should avoid excessive braking turning etc that could damage the synthetic carpet fibres.
FDo not drive on to the pitch without the prior consent of the manufacturer
FDo not apply any high static loads to the system
FProceed with care when clearing snow
FDo not use any chemicals that may damage the surface
FDo not light fires on the turf system
Recommended equipment
FManually operated sweeping machines with an hourly capacity of around 1,000 m²
or
FSweeping and suction machine, self-propelled, with an hourly capacity of up to
3,000m²
FDrag brushes and drag mats
FDrag nets and drag mats
FHand-held equipment such as a hard road-sweeping brush for brushing the infill
material into the turf system
FHigh pressure cleaner (wet cleaning with a pressure of approx. 200 bar)
FPolytan Rotamat
FPolytan Polymobil
Watering: Yes or No ?
FIn principle there is no need to water Polytan football pitches. In the event of a long
period of extremely hot weather the surface temperature of the artificial turf can, of
course, be lowered by wetting it. We recommend, however, that you only do this in
exceptional circumstances, otherwise it will become a “permanent fixture” or
“habit”. The consequential costs are unnecessary and should also not be encouraged
for environmental reasons (water consumption).
