New Geo-Grid Connector Announced






Mechanical Geo-Grind Connector


CHARLEVOIX, Mich. – Redi-Rock International recently released the testing results on its patent-pending, geo-grid connector.

Originally designed as a gravity system, Redi-Rock's 41-foot deep blocks were able to achieve between nine and 15 feet without needing geo-grid or tiebacks, due to the massive size of the blocks. Initial testing of the company's new mechanical geo-grid connector with smaller 28-foot deep blocks indicated the potential for these walls to be designed to reach 36 feet high by placing geo-grid every three feet between layers.

"The results were far better than expected, and now we have a system that is in many ways the strongest geo-grid mechanical connector on the market today," said Ben Manthei, president of Redi-Rock International.

Initial testing results indicate that Redi-Rock's mechanical geo-grid connector achieves 100 percent of the strength of most Mirafi geo-grids. One of the company's main concerns when designing their geo-connector was to keep the design simple. The patent-pending connector uses dual 3 1/2 foot long pieces of #4 rebar that intertwines in the geo-grid and is placed in a specially designed slotted groove. When placed in an "S" pattern between the pieces of rebar, a counter-rotational connector locks the geo-grid to the blocks.

"Interestingly, the majority of our connector's design came as the result of a 15 minute brain storming session between two of our engineers," Manthei said.

General Shale Sets Safety Record








KINGSPORT, Tenn. – Since 1994, General Shale's plant has operated without losing a single minute of work due to an accident. That equates to two million hours without a loss-time accident, a production rate of 1.9 million bricks-per-week, and 700 tons of raw material handled every day.

The employees of the plant had a catered steak lunch in recognition of the plant's accomplishment. The event had a western theme; employees were treated to a bluegrass band and the opportunity to ride a mechanical bull.

"I told them every time we reach a milestone, we will have a cookout," said Kingsport plant manager Alvin Hall. "We are going to celebrate and keep giving safety awards."

When Not to Use Brick

The prevalent practice of using brick for repairing and resurfacing roads in New Delhi, India, is leaving the roadways in disastrous condition.

''Bricks are not meant to be used for resurfacing or filling potholes at all,'' says traffic expert, Dr. V. K. Sood.

''Only the sub-base of the roads can have bricks. The entire purpose of using bricks at this level is that it forms a porous layer draining out any accumulating water,'' he explains.

"Brick at the upper layers allows water to seep into the roads, weakening bitumen and causing potholes," he adds.

New Delhi contractors are the culprits. They buy ''overburnt bricks'' from kilns by the truckload, as it's cheap, and use it for resurfacing and potholes.
