Retaining Wall ?

[496chevy4x4]

Looking to have retaining wall built & everyone I talk to wants to install "Allan blocks" instead of a "poured wall". Anyone got any suggestions on which one will be better. House will be located approx 3ft from wall. I'm thinking poured wall will be better but not sure. Any one have any suggestions or can reccomend someone in the gainesville area to give me an estimate?

Thanks

How tall is the wall ? 3' is awful close to be able to get a good foundation for a poured wall or a set back for the stepped block . Either company should be able to tell you exactly what you need . A stepped wall looks better than just a poured wall . IMHO

According to the few that I've had come out & take a look, it averages about 4ft (about 3ft on one end, 2ft in the middle & 5 ft on the other end & 40ft long). The way the lot & septic system is situated I can't put in basement(rather small lot which borders the corps property), did have one builder say the wall could be used as part of the foundation if I went the poured route but he won't get back to me w/price.

If anyone know of someone in this type work, shoot me there name & number.

if the wall is an average of 4' tall it will have to be designed by an engineer, approved by hall county, and permitted. allen block walls will last just as long as poured concrete if done properly and most of the time cheaper as well. if the wall height is an average of 4', the geogrid embedment has to be at least 80% of wall height, more importantly proper drainage and soil behind the wall are very critical, stacking even 84# allen block 5' tall is not structural, they must be tied into ground with the grid. if you would like i could send you a diagram of how wall should be constructed so you could get a better idea. too many walls have been done improperly and fallen, just dont want to see anyone spend good money on a poorly constructed project. thanks

Make sure to use tons of tie-backs (deadmen) what ever you want to call them. I've seen a wal fall then you've got 3X the problem you started with.

We just poured a 200' concrete retaining wall on one of our projects, and surprisingly, it was cheaper than blocks. Just remember that you are going to have a big "T" shaped footer at least 1' underground on the low side. This is a lot of concrete, but on the flip side, my engineer did not make us tie it back as long as we had 98% compaction behind the wall. At 4' high, the footer needed to be 8" deep, 4' wide (1' foot in front, the rest behind), and 8" thick. This design lets the weight of the dirt on the backside of the footer actually stop the wall from coming forward. Good Luck. Zack
