Allan Block Technical Newsletter Issue 10 Allan Block and No-Fines – No Problem

Woodland Heights, a 30-unit townhome association built in the 1980’s, needed to replace its second timber wall. However, numerous site constraints did not allow enough clearance to install geogrid reinforcement within the property limits. Based on site constraints and project goals, Duffy Engineering and Associates called for the use of ‘No-Fines’ concrete backfill with an Allan Block AB Classic wall. Duffy utilized AB Walls 10 software’s alternative reinforcement option to design the wall and confirm that all safety factors were exceeded.

AB Fence Gets the Thumbs Up From SCDOT

Wednesday, June 29th, 2011

Allan Block Technical Newsletter Issue 9: AB FenceAs with any community that once considered themselves small, the community of Mount Pleasant, South Carolina has seen major population growth over the years. With this growth the traffic congestion and noise have continued to increase to a point that South Carolina Department of Transportation (SCDOT) traffic studies gave the US 17 corridor a ‘D’ Grade. This poor grade was only projected to get worse, forcing the SCDOT and the city to develop a plan to expand and upgrade the corridor.

The upgrade was not only to relieve traffic congestion but also to reduce the increasing noise problems to the surrounding residential neighborhood. Mount Pleasant had no sound walls anywhere in the city and for their first they wanted to set a high quality standard. The city chose the AB Fence System with the four block Ashlar Blend Pattern for its aesthetic quality, its performance in reducing noise and its competitive cost.
