TREE PIT CLEANING & MAINTENANCE
The Tree Pit surface should be regularly swept clean, removing leaves and detritus material in order to prevent moss growth or possible tanning staining.
If the surface has been contaminated with chewing gum it is best removed by freezing and chipping off as necessary.
Annual checks should be to check for possible damage to the tree trunk, if the growth of the tree is affected by the Tree Pit installation the Tree Pit finish should be cut back as required.
The Tree Pit surface has been designed for normal pedestrian usage only, therefore protection should be provided wherever possible against abnormal usage.
Abnormal usage applies to heavy objects such as skips, these should not be dragged across the surface, the Tree Pit must be protected in this instance to avoid any impact damage, staining etc.
General cleaning of the Tree Pit surface can be carried out by cold pressure washing up to a maximum 150 bar rating to remove dirt and grime.
The water should be applied using a fan type lance which should be kept 200mm above the installed Tree Pit. Care should be taken however to prevent damage to the surface with excessive water pressure.
If the surface is contaminated with any cement or concrete marks these can be removed using dilute hydrochloric acid or a proprietary cement remover.
In all cases we recommend that a small area is carried out first to confirm suitability.
Oil stains should be removed as soon as possible, use a mild detergent as required to prevent possible staining.
Damaged surfaces should be repaired as soon as possible. Please contact the contractor who installed the surface.
