Last year we did a fair number of stoops/stairs made with Brussels block. This spring I already have three that need to be repaired after only one winter. I did one of the installs and someone else I work with did the other two. Mine failed due to new construction and I guess I didn't compact the backfill enough. (is there ever really enough?) I am just curious how many of you also build stoops with the block and what you have done to combat settling. I work from the bottom up, compact with as much equipment as I can but usually use a hand tamper in 1-2" lifts. Other than adding in some portland cement to the crushed limestone base I am not sure what else to do. I have done many in the past but these ones from last year have me baffled. Thanks.
