Tri-Lock
Tri-Lock is a permeable, flexible, interlocking concrete erosion control system that provides a high level of hydraulic stability and erosion control in both open channel flows and waves.
- Tri-Lock is available in several sizes and thicknesses to accommodate a wide range of hydraulic conditions.
- Tri-Lock does not require cables and may be hand-placed. For underwater or machine placement, Tri-Lock may be cabled onsite or delivered as mats.
- Tri-Lock has a unique three-directional interlocking geometry that allows it to traverse changes in terrain and be placed around corners without disrupting the placement pattern or using seams.
- Tri-Lock may be backfilled with crushed rock to provide a durable surface or backfilled with soil and vegetated to provide a more natural appearance.
