Astro pitches can develop problems over time such as flooding, ponding, moss and algae sludge build up making the surface unpleasant to play on and in some cases dangerous to players.
A ‘rejuvenation’ can make an astro pitch drain better , reduce algae sludge, moss and improve shock absorption for players.
Algal sludge on pitch typically occurs in autumn or spring. As alage love warm damp condition they can ‘bloom’ very quickly giving a artificial sports surface a muddy appearance. Short term the algal can be removed from the surface using a rubber squeegee and brushing the surface. The algal will however reappear at the first opportunity and cause further problems. A complete rejuvenation will often solve this problem in the long term.
Moss and Leave should be removed from an artificial grass as soon as practically possible. If allowed to establish a sports surface can become unusable a rejuvenation would then be required. A deep clean can remove heavy moss contamination and restore a surface. However the spores are left in the sand and may reoccur if not kept in check.
A compacted surface feels very hard under foot and it will impede drainage. As part of the rejuvenation process the carpet fibres are separated and the infill agitated.
The rejuvenation process uses high pressure compressed air to extract the existing infill, including the built up contamination, from the synthetic grass carpet prior to new infill being applied and brushed in. During the process the carpet fibres are opened up and separated therefore the surface is decompacted.
The rejuvenation process is very successful in restoring the drainage of a surface and resolving ponding and algal problems. It is usually carried out on a synthetic grass sports surface after a period of between 5 to 10 years depending on use, location and usage. Courts of this age typically begin to suffer from slowing in drainage and build up of moss and algae. Rejuvenation of a pitch may extend its lifespan so saving clients cost.
The process can be carried out all year and “all weather”, bring courts back into play all year for players enjoyment.
Extract the infill using the rejuvenation unit.
Collect the contaminated infill.
The contaminated infill is removed.
New clean infill is applied to the artificial turf.
The rejuvenation process aims to restore the infill in the carpet, lift and decompact the artificial grass fibres , and decompact the infill not removed.
This process allows the courts drainage system to work as a ‘new’ system would. Rainwater normally percolates through the artificial grass and infill. Overtime dirt, vegetation and debris filters into the sand and carpet fibres. They block the air holes between the sand particles and provide a medium for moss and algae. By replacing some of the sand infill the debris which has built up is removed and allow the artificial grass sports system drain.
We don’t recommend a pitch rejuvenation by using a pressurised water system. Initially result can appear to be comparable, whoever the pressurised water drives contaminates deeper into the infill and turf. The bottom layer would be more contaminated which would impede water through the system, and make the higher level of sand not drain as well. This would again provide a medium for moss and algae to take hold quicker.
