Water creates pressure
Soil behind a retaining wall can hold water. Without a plan for drainage, that water adds pressure to the structure.
The site slope and runoff patterns should be understood before construction begins.
Every site is different
Wall height, soil, nearby structures and access all influence the design and scope.
An on-site review is necessary before recommending a solution.
Ask what is included
The estimate should identify preparation, wall construction, drainage provisions and cleanup.
Warranty details should also be documented for the specific project.
