The pressure on the side facing earth must be the same as that on the outside. If the soil has gaps with less pressure, then the sea wall is not correctly secured. The sea wall may crack and, in extreme cases may collapse. This video shows how companies make seawalls and complete seawall repair.

The first step to maintain your property is to stop soil erosion. Remember, a small sinkhole on the surface can represent an even larger hole beneath the surface. As an area begins wash out underground in the normal course, it’ll expand and rapidly move away if to deteriorate. It’s clear that repair is necessary when the accumulation of ground and stormwater was traveling underneath the seawall, and passing through its joints as well as small imperfections. This results in a 5-foot thick solid, impermeable layer of grouted material that is 4 feet above the foundation for the wall. Thus, the grout wall now supports the seawall and prevents the soil from being eroded by water through its flaws. vit3vr6gua.
