Proper Construction of a Retaining Wall
Building a retaining wall correctly is essential for safety, durability, and long-term performance.
One of the most common causes of retaining wall failure is hydrostatic pressure, which occurs when water builds up behind the wall and pushes against it.
In a poorly constructed wall without drainage, water becomes trapped in the soil.
As pressure increases, the wall can crack, tilt, or completely collapse.
This creates serious safety risks and costly repairs.
A properly built retaining wall includes a drainage system behind the structure.
A layer of drainage gravel allows water to flow freely downward instead of building pressure.
Weep holes at the base of the wall provide an exit for trapped water, safely releasing it away from the structure.
When drainage is correctly installed, the wall remains stable, strong, and resistant to erosion. Proper construction not only prevents structural failure but also extends the lifespan of the wall and protects surrounding landscaping.
In summary, drainage is the key difference between a failed wall and a stable wall.
Any retaining wall should always be designed with water management in mind to ensure safety and long-term success.
