How to Build a Retaining Wall

I am building a retaining wall 100'long
x 3' high. I am using a retaining wall block (4"x8"x12"). I had the trench dug out and is packed down pretty solid. Do I need to use a leveling sand underneath the first level of block?

I think the worry is the dranage, that is why they use crushed gravel under the wall. If you are in a colder climate you will want to make sure the wall drains well to prevent frost from pushing over your wall.

i would like to know the basic steps in building a retaining wall and is it possible to remove an existing retaining wall and transfer it to another spot by reinforcing it,if so how should this be done?? reply a.s.a.p.

I am building a retaining wall in front of my mobile home. We have taking away the dirt in front of the mobile home and now are ready to put in a 6 foot by 50 foot wall. How would be the best way to go on this.
Would concrete block work or should we sent form and pour solid concrete. The mobile sits on a filled area on a hill side.

Thanks for your help

How long will it take a retainer wall to dry if 36 inches high and ten inches in width? Thanks.

I plan on building 2 sets of steps out of segmental blocks. Both will be slightly curved, and either 3 or 4 steps high, depending upon the final height of the deck. One is in central Florida, one in Kelowna, BC, and that one has a high water table. There is already a 4"concrete pad on the Florida property, and proposed concrete for Kelowna. How do you properly secure the base to the concrete,(construction adhesive?) and do you need all the angular fill as per an earth based wall and steps? I'll also want to install a railing for safety, so the end row I'll be filling with concrete. The entire back wall of the steps will be stone, as it will be continuing off to one side as a decorative base wall for the deck. Is 4" concrete enough thickness for either one, and should the Kelowna construction be more than a gravel and sand packed base to allow for frost?

I built a retaining wall over a year ago along the side of my driveway. The wall is 50 ft long by about 9 ft high. We recently had about 5 inches of rain fall in a 24 hour peroid and caused the middle portion of my wall to give out. I have started the rebuilding process but want to know if I should consider cementing the base row of my blocks?(that was what caused my wall to fall, two base blocks tilted)

I would like to replace an existing railroad tie retaining wall. It is 5 feet tall and is split into two levels, with about an 18" setback between. It has been in -place for at least 45 years and is rotten in places and starting to fall apart - not I hasten to add from pressure. I would like to replace it with stone - but for the expense. I find the concrete blocks on offer rather unappealing and would like to achieve the effect that stone walls have, both from thier looks and by being able to introduce various plants bewteen the blocks/slabs/whatever to break up the monotony. The upper surface will be a paved terrace area with potted plants etc on it, but it will not be supporting any more weight than it currently does. The total length of the wall is about75 feet. Any help or suggestions would be much appreciated. Incidentally I got a quote for stone to do the job and it was $48,000 at the suppliers!
