We all know that Artisan Precast concrete walls are a beautiful addition to any project. But sometimes, the hardest part of the job is figuring out what is under the wall. A great deal of excavation and exploration goes on underground before a wall ever goes up.

In a residential development in Allen, Texas, we were going to build a beautiful 8-foot Brickcrete wall. And every 25 feet, we were going to add brick columns to add to the luxurious aesthetic of the neighborhood. But there was one tiny problem. The main water line was running along a substantial portion of the fence line.

Our typical 4-foot-deep piers were out of the question for this project. So instead, we decided to build a continuous footer to span the 30- to 40-foot stretch that was above the water main. The footer was 2 ½ feet deep and 4 feet wide. In the end, we had a lovely 8-foot Brickcrete wall in a neighborhood. And you would never guess that the neighborhood’s main water source was running right under it.

Hidden Obstacles Underground

Typically, our four-man crew has very little problem augering out piers with a skid-steer. But sometimes the ground fights back. Currently in Cedar Park, Texas, the wall that we are building is going to be sitting not on soft soil but on solid rock. This is no simple digging; we had to get a hydraulic auger jackhammer attachment. For a stretch of 80 feet, we used the breaker to pulverize the rock just to dig the piers.

We also used a special rock bit to drill through rocky ground in Denton, Texas, but with a different kind of added danger. Underground was a natural gas line, so we used a hydro-excavator to dig the piers.

Before our walls go up, we take the time to find out what is beneath us. That way, we can assure that the job gets done safely and effectively.
