Tag: articulated concrete block

An articulating concrete block system is comprised of a matrix of individual concrete blocks placed together to form an erosion-resistant overlay with specific hydraulic performance characteristics. The system includes a geotextile underlay compatible with the subsoil that allows hydraulic infiltration and exfiltration to occur while providing particle retention. The blocks within the matrix shall be dense and durable and the matrix shall be flexible and porous.

Strong Streambanks: Beauty and Function

Streambank stabilization projects are a large part of business for erosion control design companies and contractors. Municipalities around the country are undertaking such projects for a variety of reasons: Replacement of old measures, such as concrete linings Heavy rainfall or wave action causing undercutting Increased runoff because of development upstream

Pavers can be made of concrete, shale, or polymer, and they come in individual stones as well as mats that can be laid mechanically or manually. The base is usually a minimum of 12 inches deep. The gaps between the pavers may be filled with gravel or topsoil seeded with

Above Fountain Creek, on the Fort Carson military base in Colorado, sits a railroad bridge spur. Luke Tourville of Gracon Corp. was asked to come in and perform some analysis for protection of the bridge piers. “The bridge is 275 feet long, from abutment to abutment,” he explains. “There are

Meeting the Velocity, Meeting the Volume

A group of property owners in the New Uri watershed, encompassing Florence, KY, began to complain to city officials about erosion from a 10-foot-high streambank that was taking a sharp turn in their neighborhood. The erosion was so significant that some property owners were losing their fences to cave-ins. From

In any economy, but especially during a recession, it’s no secret that reliability is the primary concern for contractors across the United States. Building materials at a construction site must perform the job they have been designed to complete, and perform it effectively the first time they are used. Today

A Method for Every Season

A wide range of erosion problems of varying scale and complexity lend themselves to a common solution: channel armoring, a practice that has evolved from simply lining degraded channels with piles of stone or blankets of concrete to include a broad assortment of materials and techniques. The city of Houston,

Stabilizing the Stream

Stabilizing the Stream

Many techniques are available to stem erosion of streambanks, to prevent flood damage, and to help restore the natural function of a stream or creek. This article looks at several different examples. Underwood Creek Located in metropolitan Milwaukee, Underwood Creek is a major tributary of the Menomonee River. Dale Miller,

Daylighting Streams

Daylighting—the practice of restoring a stream that had been routed through a culvert back to its natural state—is becoming a more common stormwater trend throughout the United States. By taking the stream out of the concrete channel, daylighting allows for infiltration, and it improves downstream water quality by removing pollutants

Walls and Blocks

Walls and Blocks

Retained materials, whether they’re rock, soil, or stormwater, always have a tendency to move forward and downward with gravity. Holding them back calls for all the ingenuity at engineers’ disposal. Concrete fabricated to form articulated concrete blocks (ACBs) and joined together into mats can help prevent erosion from runoff. They’re
