Supporting a Deck With a Retaining Wall

Problems with this job included a sunken backyard, poor drainage, and an old retaining wall that had to go.

Because of the tight site, the excavated dirt had to be hauled away.

A concrete footing — like what you’d use for a basement wall — was poured to support the new retaining wall.

A mason fills the rebar-containing cells in the concrete-block retaining wall with grout.

Portland-cement plaster and a coat of tar makes the wall water-resistant and prepares it for stone veneer.

PVC pipe and crushed stone drain the wall. The ground below the deck was graded toward the wall, and then covered with crushed stone.

Epoxy anchors and bolts secure the ledger to the retaining wall.

Galvanized steel helical-pile footings were driven to support a drop beam at the stairs.

With the ledgers installed, framing was typical. The blocking will support seam boards in the decking.

After the decking was complete, cultured stone was applied to the retaining wall.

Concrete pavers provide a stair landing and a path to the deck.
