LOCK+LOAD supports earth retention using the standard design concept of a cantilever. The panel and counterfort sections when combined create the LOCK+LOAD Cantilever Unit. Each LOCK+LOAD unit stabilizes a block of compacted soil, in essence creating a self-stabilized soil block with a concrete face.
The slender panel design of the Cantilever Units maximize land use and accommodate fences or barriers right at the wall face due to their strength, as demonstrated by resisting the compaction of the backfill.
LOCK+LOAD is comprised of a panel (90lbs) and counterfort (40lbs). The Unit is manufactured utilizing wet cast, air-entrained, fiber and steel reinforced, 5500 psi (38 Mpa) concrete. Shipping is done on pallets, each pallet holding 14 units, weighing approximated 1850 lbs and providing about 50 square feet of wall face (4.6sqm).
Without additional soil reinforcement, LOCK+LOAD is considered a gravity structure that can be used to create walls 4 rows or 5’ 4” (1.6 m) high. Taller walls require the Cantilever Units to act as a stabilized soil facing for a larger reinforced soil structure such as : Mechanically Stabilized Earth (MSE), Geosynthetic Reinforced Soil (GRS), Soil Anchors and Nails. LOCK+LOAD installation remains virtually the same, as only the additional soil reinforcement may vary in length, type and location. Since Cantilever Units are independent there is no vertical accumulation of stress.
These LOCK+LOAD walls behave as a true Mechanically Stabilized Soil Mass with non-extendiable reinforcement using common MSE analysis methods.
