Gravel-Lok Contractor Custom Stoneworks of Baltimore used Gravel-Lok to fill in tree grates along a city street in Baltimore, Maryland. Traditional methods require expensive iron tree grates that need to be replaced as the tree matures. Eventually a fully mature tree will require the grates to be removed which creates a safety hazard along sidewalks. The open pits also collects trash and other debris which detracts from the beauty of the city.
Gravel-Lok is environmentally friendly and allows water to filtrate through to the trees root system. It also fills in the void left from the vacant tree grate which not only enhances the appearance of the community but the safety as well.
