Erosion Under Area Way Steps Solution

Posted by: Drainage & Erosion on Jan 16, 2010

A very common problem that we see is severe erosion under area way basement steps.  The cause of this problem is a combination of a complete lack of a proper compacted gravel subbase to prevent erosion and using uncompacted soil backfill directly under the concrete as it's being placed.  We solve this problem by excavating a loose material from under the steps, placing a compactable gravel subbase (typically VDOT 21-A when in Virginia), re-grading the surface for positive drainage away from the structure, and stabilizing the ground surface with either sod or a decorative stepping stones and gravel.  It's also important to install a buried downspout extension, if there happens to be a downspout in the area, which often aggravates the situation if the downspout is allowed to drain the gutter water next to the steps.
