Ankalok is a precast concrete revetment block system for erosion control, using a unique double anchor head shape to secure each unit through full six-point interlock. Tapered sides support curved placement and enhance flexibility on varied terrain.
Six-point interlock reduces risk of vertical displacement under hydraulic or mechanical load
Tapered edges enable articulation down to a 0.5m radius for non-linear alignments
Soil or gravel infill increases friction and stabilises the revetment under differing conditions
Open cell design facilitates pore water pressure release to reduce uplift
Vegetation growth through the structure enhances long-term slope stability
Straightforward manual installation without heavy lifting equipment
Suitable for locations with limited site access or constrained working areas
Additional restraint possible with timber or steel pegs where toe support is insufficient
