Water stress build-up is caused when groundwater is not drained pipes from behind the seawall. Groundwater versus a seawall can be from the area's all-natural water-table, rainfall percolating into the ground behind the wall and waves overtopping the wall surface. The water level can also increase during durations of high water (high trend).

The enhancement of seawalls near marine ecosystems can result in raised shadowing effects in the waters surrounding the seawall. Stalking lowers the light and visibility within the water, which may disrupt the circulation in addition to foraging capabilities of specific types. The sediment bordering seawalls tends to have less beneficial physical residential or commercial properties (Higher calcification degrees, less architectural organization of crystalline framework, low silicon material, and less macroscale roughness) when compared to all-natural shorelines, which can offer concerns for types that reside on the seafloor.

It involves covering components of the seawalls with particularly developed floor tiles that resemble natural microhabitats with holes and other features that more carefully look like natural rocks.
