Landscape Retaining Walls Windsor

Step 1, Confirm survey, height, slope, surcharge, geotechnical condition, wall design, utilities, drainage, access, finishes, and adjacent features.

Step 2, Excavate to stable foundation, control water, and construct a level compacted granular or concrete base as specified.

Step 3, Set facing and drainage, place approved fill in lifts, install reinforcement or connections, and survey alignment and batter.

Step 4, Coordinate corners, steps, curves, stairs, fences, plantings, outlets, and transitions without cutting structural components.

Step 5, Finish coping, toe, swales, erosion protection, and final grades, then document materials, density, reinforcement, and survey.

Harrowgate builds retaining walls as drained soil-structure systems. We establish stable excavation, construct the designed foundation, place the structural wall and reinforcement in sequence with controlled backfill, and complete surface drainage so groundwater does not accumulate behind the finished face.

Survey, utility, and excavation planning. We stake wall alignment, top and bottom grades, steps, curves, and property limits. Utilities are located, and nearby foundations, pavements, trees, and slopes are reviewed. Excavation width accounts for geogrid length, drainage, formwork, and compaction equipment. Temporary slopes or shoring follow the site-specific excavation plan.

Foundation or levelling pad. Segmental walls receive a compacted granular levelling pad or concrete base where designed, accurately stepped at grade changes. Cast-in-place walls use reinforced footings founded at the specified elevation and bearing condition. Soft, wet, organic, or disturbed material is removed rather than hidden beneath extra bedding.

Drainage system. Clean drainage stone is placed behind the wall with filter separation from retained soil. Perforated collector pipe is set to positive fall and discharged to an approved outlet, with cleanouts where detailed. Through-wall drains, weeps, and surface swales remain open. Waterproofing is added on concrete walls where the design requires it.

Wall and reinforcement construction. Segmental units are levelled course by course, connectors seated, and cores filled where specified. Geogrid is laid flat at the exact elevations and lengths, tensioned, and placed with correct orientation. Concrete walls receive reinforcement, forms, joints, embeds, consolidation, and curing under the structural drawings.

Backfill and compaction. Specified reinforced and retained fill is placed in thin controlled lifts, with density testing where required. Equipment size is limited close to the wall so compaction force does not displace units or overload fresh concrete. Geogrid remains undisturbed, and construction traffic does not turn directly over unprotected reinforcement.

Caps, guards, and grading. Caps are bonded or anchored as specified with movement accommodated at joints. Fence and guard posts use designed sleeves, foundations, or wall connections rather than improvised cores. Final grading directs runoff away from the back of wall, stabilizes the toe, protects outlets, and restores adjacent pavement and landscaping.

We survey wall alignment and elevations, inspect bulges, open joints, caps, outlets, erosion protection, and guard connections, and verify finished grades against the design. Construction records identify foundation observations, drainage stone, pipe, geogrid lots and elevations, fill lifts, density tests, concrete, and concealed reinforcement before cover.
