Building Materials

Match spike length to the material being anchored: shorter spikes hold timber edging and light retaining materials, while 10 to 12 inch and longer spikes anchor landscape timbers, sleepers, and heavy edging in soft ground. In sandy soil, step up a size, since holding power comes from soil friction along the shank.

Geogrid ties the wall face back into the compacted soil mass behind it, turning the backfill itself into part of the structure. Most segmental wall systems require grid layers above a certain wall height. Follow the wall manufacturer's spacing and embedment specifications, since geogrid placement determines whether the wall stands long-term.

Use a landscape-rated construction adhesive to secure cap units, treads, and veneer that mortar would make too rigid or that cannot be pinned. Surfaces must be clean and dry, and most adhesives have minimum application temperatures, so check the cartridge before cold-season installs.

Metal components offer the highest strength and a thin profile for crisp lines, while composite products resist corrosion and ground contact rot without treatment. Soil chemistry, expected loads, and the look the client wants drive the choice more than price alone.

Yes. Spikes, anchors, adhesives, and related hardscape materials are stocked for contractor-scale orders, and volume pricing is available by quote. Ordering full-job quantities up front avoids mid-project supply gaps that idle a crew.

Slope work generally calls for long-shank spikes, anchoring pins, and stakes that penetrate below the disturbed soil layer into firm ground. Pair anchors with the fabric, blanket, or edging product being secured, and increase anchor density on steeper grades and in loose or sandy soils.
