Pebble Tec repair

[JKnight]

Throwing this out there since we have a community of tradesman and industrious fellows... The previous owner of our house had the entire 10'x50' covered patio covered with what seems to be pebble tec pool material. It's really quite nice but about 20% of the patio has areas where the pebbles are coming loose, particularly in the areas that are exposed to sprinkler overlap or runoff from potted plants. They also applied the same material to all uncovered concrete paths throughout the yard and they are falling apart very badly.

Is this typical and does anyone know about the options for repairing the damage and preventing additional degradation?
