Soil is heavy, especially when soaking wet from a what planes do british airways fly to new york rainstorm, so a basic retaining wall four feet tall and 15 feet long potentially has to support up to 20 tons of soil pressure.

Any discrepancies here will show up higher in the wall. A wall that leans into the soil it retains is less likely to be pushed outward by soil pressure than a plain-old vertical wall. Design and build your retaining wall to slope at a minimum rate of one inch for every one-foot of rise height. The locking flange on the bottom edge of every block guides it to click into position slightly behind the lower block, preventing the top blocks from being pushed outward.

Groundwater is the natural enemy of retaining walls. When it saturates clay-type soils, they swell and put excessive pressure on the backside of the wall. To avoid failure, make drainage provisions at the same time as you go about building the retaining wall. The perforated pipe will carry groundwater to each end of the wall where it can drain harmlessly away. The ends of the drainpipe should then exit on each end of the wall, and you may cover them with crushed stone to camouflage their appearance.

After your drainpipe is in place, you should backfill the rest of the space behind the blocks with either sand or pea gravel—either will allow retainng to filter through to the drainpipe at how to check dc amperage base of the wall.

For the best results, backfill with a few inches of the material after laying each course of blocks, and use a hand tamper to compact the material.

When building a tiered set of retaining walls, position the higher wall behind the lower wall at twice the distance as the height of the lower wall. For example, if the lower wall is three-feet high, the hkw wall should be set back at least six feet from the lower one. This keeps the higher one from creating pressure on the lower one.
