Creating a Rock-Solid Retaining Wall

Retaining wall made up of blocks are very heavy. You do not want to lift them the second time around. The following are some of the steps on how to create a long-lasting retaining wall:

1. Make a Base Composed of Crushed Stones

The professional and highly skilled builders prefer to use crushed stones in building a base instead of gravel came from a pit. Crushed stones are much more expensive compared to gravel. However, it provides you with better drainage and it needs less compacting since the crushed stones have sharper angles. Once the crushed stones are compacted, they remain that way. In addition to that, you should avoid rounded stones such as river rocks or gravel because they do not form durable interlocking bonds unlike the angular stones. You will actually see almost perfectly compacted base as soon as the crushed stones are laid in the trench. As a matter of fact, the same kind of stones is used for backfilling that also get rid the need for moving multiple materials.

2. Sweep Prior to Stacking

Even a tiny pebble on the block’s surface will throw out the one that is above it. That crooked block will definitely affect the ones on top as well. Furthermore, the small stone could create a top course that has unattractive hump.

3. Get your First Course Right

Apply a torpedo level in leveling each block back to front and a four- or six-feet level in order to keep every course even and level. Set the blocks with plastic mallet or heavy rubber. Getting the first course level or flat is very important therefore, take your time building it. Try laying the course as near to the middle of the trench as you possibly can.

4. Retaining Wall Drainage

It is a very essential part of building your stone wall. Once some rows have already been stacked, backfill the retaining wall with rocks so that it matches the height in front of your wall, then lay down a porous drain tile above the rocks. Create drain tee fittings as well as a drain grate one every 25 to 50 feet depending on how much rain water is expected to come down to your wall. Then, cut one block down in order to make room for the drain grate. Afterwards, screw the parts of the drain tile together so that they do not come apart when covered with some rocks. Drain the tile at the end of the walls when necessary.

5. Step Up After 2 Full Courses are Sub Grade

If your walls run up a hill, resume every base course towards the hill until the second course is basically leveled with the grade. Then start the second base course from that point. If you’ve got the option, it may be much easier to excavate and put the lowest course prior to excavating the trench, especially if you’ve got to step up many times. Save some of your money and install the much cheaper color or style which matches your wall pattern.
