Yes sir, pushing the "envelope" by contractors and some designers on the systems does seems to be a practice in the marketplace. With multi depth systems falling under AASHTO design methodology we will hope there is less wiggle room to push that envelope. You are correct, the intent is...

I am a marketing and technical person for a SRW company. PCB's are certainly growing and have there place. Height for most are an issue. Depending on the systems economically they max around 15 plus feet. But as you suggest with geogrid they can go much higher. Again as you stated...
cdstan, unfortunately I am not familiar with the program but if you need help on a Modular block MSE wall let me know and I can help or put you in touch with folks for SRWall or MSEW programs.
BigH, thanks again, I know we have done a number of walls in front of pools but have never had a firm confirmation on the nature of the load. We have always left it to the wall designer to work it out. Now I have a designer wondering which is the right way. I will look into getting a standard...
Sorry BIG H, it will be below ground gunnite with a paver deck around the pool. New information says it may be 6 feet away from a 8 foot height section so it will be in the zone of influence.
I thought a dead load of 150 to 250 psf might be in the range but just do not have the experience as...
What loading should swimming pools be given behind MSE walls? There seems to be differing opinions out there. Assuming the pool load is within twice the height of the wall.
The advice on design with respect to height and distance of tiers are correct. The success of the structure then will be on achieving the compaction on the lower walls. I might highly suggest if this is a residential structure with your stamp on it that you request compaction testing be done...
Sounds like you did all you could do and more and had reasonable outcome. I do have a question. Did the wall installer step the zone between the retained soil and the reinforced zone? As you know if they make a slope cut it allows for a slip zone and differiential settlement. I have seen...
A lot of great suggestions, may I follow up on MSEMan's comment. From my screen name you can tell my area is MSE segmental walls. Most steep slopes are a red flag for global. Wall designers will usually tell us that global has or has not been performed and then suggest that it be done if...

If I have the right picture, the reason for adding the weep holes would be to alevate the possiblity of hydrostatic pressure in the future behind your backfill. If you were to capture any water coming through the wall because of the weep holes by using a type of chimney drain and...
Since no one was specifically mention segmental retaining wall blocks Elfman, I will. These are usually 8" tall by 18" wide and 12" deep. There are a number of variations on sizes. These systems usually combine a block and geosynthetic to make a soil reinforced wall. Except for wood, gabion...

Using a 8" tall by 12" deep modular block, with 28 degree soil (assumed poor) no real load on the wall you should put one course of geogrid (2.75')on top of the second course to be safe. If the soils are better and you have good drainage away from the wall you might get...
Solutioninc makes a good point. CCLIN help us by letting us know the need. It appears to be a barrier wall for trafffic, I am correct? If you were to consider a segmental retaining wall with a parapet wall on top, you would want to be a least 2 times the height away from the slope edge. You...

We do. This is a link to our old site. We are working on a more interactive site that will work with our CD. We hope the new site is up in October.
