Ultralok Unit

UltraLok™

Submar 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. UltraLokTM 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. UltraLok interlocking blocks come in varying heights to accommodate multiple types of erosion problems.

Each UltraLok block unit gains strength and durability by interlocking with its neighboring units. Over time, the UltraLok installation becomes part of the landscape providing the ultimate in erosion control.
