Basalt driveway patio restoration

Description: The driveway patio has been cleaned by the previous contractor using the jet wash and plenty of acid-based products.
Due to the texture of the stone, the floor kept a lot of acid residues, juice and dirt, resulting in a white snow floor rather than grey (the natural stone’s colour).
We’ve managed to stabilise the floor and remove the damages mechanically from the previous contractor without changing the floor’s texture.
The stone has been treated with colour enhancing sealant (X2 coats) to bring back “the formal glory”.
