Rebuild leaning block walls and loose interlock steps with a proper footing and drainage behind them.
A segmental block wall leans when water builds up behind it or the base under the first course settles. Rebuilding means taking it down, setting the first course on compacted base below grade, and backfilling with clear stone and a drain pipe.
Interlock and precast steps at the front door shift the same way driveways do. We reset them on a compacted base and glue or pin the caps.
Taller walls can require an engineered design and a building permit from the City of Ottawa. We tell you before quoting if yours is in that range.
Lift the sunken or heaved section, fix the base, relay the same pavers and compact them level.
Full excavation, a compacted granular base built for Ottawa frost, and pavers rated for vehicle traffic.
Clean out failed joints, refill with polymeric sand, and seal if you want colour and stain protection.
