Walls that hold — and look like they belong.

Walls that bow, lean or topple don’t fail because the blocks were bad. They fail because water built up behind them. Saturated soil exerts enormous lateral pressure — easily several hundred pounds per square foot — and a wall designed only for the weight of dry soil can’t hold it back.

Every wall we build gets a free-draining stone backfill zone (3/4" clean angular stone) wrapped in non-woven filter fabric, a perforated drain pipe at the footing daylighted out to grade or a drywell, and compacted backfill behind that. Hydrostatic pressure never gets a chance to build.

Segmental retaining wall systems (Versa-Lok, Cambridge, Allan Block) are our default for engineered walls — predictable strength, clean lines, integral caps and corner units. Natural fieldstone or boulder walls are used where the property calls for an organic, less formal look, and on smaller height changes where a dry-stacked wall is appropriate.

For grade changes over 4 feet, we tier walls with a planting bench between courses. Two 3-foot walls with a 4-foot planted bench between them perform structurally better than one 6-foot wall, look softer in the landscape, and often don’t require the engineered drawings a single tall wall would.

By Long Island code and manufacturer spec, retaining walls over roughly 3–4 feet of exposed face (varies by block system and soil) require geogrid soil reinforcement — geosynthetic mesh tied between courses and extending into the backfill, effectively making the soil mass itself part of the wall. Walls over 4 feet typically require an engineered drawing and a permit.

We don’t skip either. We size geogrid to the wall height and soil type per manufacturer charts, pull the necessary permits, and coordinate with a licensed engineer when the wall needs stamped drawings.
