Dura-Hold II ®
Dura-Hold ®II has the same visual appearance of Dura-Hold, and is generally used in conjunction with Dura-Hold for areas of a project where the massive size of Dura-Hold is not required but the look needs to be maintained. Each module weighs 940 lbs (426 kg) - which is half the weight of Dura-Hold - but the installation rate/coverage is the same. From a cost standpoint, Dura-Hold II is very efficient.
Applications – Structural retaining walls for large embankments
Capacity – Gravity walls up to 39” (1m). Geogrid reinforced walls up to 23 ft. (7m)
Recommended Base Stabilization – one layer of DriveGrid™ stabilization grid between subgrade and base material. Use under Standard Base or Permeable Base.
Standard Base – Min. 6” – 8” of ¾” Crusher Run gravel (any road base standard in accordance with ASTM-D2940) compacted to 98% Standard Proctor Density (SPD).
Alternative Permeable Base – Min. 6” – 8” of ¾“ clear open-graded stone compacted to achieve full particle lock-up and consolidation. (Clear open-graded does not compact but does consolidate slightly by rattling the particles together.)
Leveling – Leveling large retaining wall blocks directly on top of gravel is difficult. U-Grip™ Base units or universal base pads are recommended under most Unilock walls for improved accuracy and make for a speedier installation. For Durahold II, turn the U-Grip base units 90 degrees for a larger front to back latitude for the blocks to sit on. For larger projects, it is recommended to install a poured concrete leveling pad reinforced with rebar. You must ensure that the concrete is poured and finished perfectly in order for the blocks to sit properly without cracking.
Connection – features a tongue and groove connection.
Handling – This is a mechanically placed wall system. Special clamps for lifting are available for use during project.
Coping - This wall requires the Durahold II specific coping. Coping attaches with tongue and groove connection. No adhesive required.
