S UBMAR UltraLok™ Interlocking Blocks are designed for maximum erosion control while promoting vegetative growth.

They provide for easy, economical installation in areas prohibitive of heavy equipment due to confined situations or areas that are hard to reach.

UltraLok blocks are manually installed over a filter fabric which allows for proper drainage and vegetation adding lasting benefits to property.

UltraLok blocks can be installed in stages as a project progresses or as a budget allows. They are an excellent solution against erosion in light to moderate water flow as well as open channel conditions.

The interlocking blocks come in varying heights to accommodate multiple types of erosion problems. The end result will be a synergy of hard-armor strength and performance with nature’s fragile development into a self-mitigating green site.
