Residential landscape retaining walls can be built to solve the structural problems of the landscape, to improve both the aesthetics of a property, o. There are several options depending on what you want to achieve. The cheapest is to use a single block of wall fixing system in which all units have the same size. A more advanced and more expensive is the installation of a multi-piece or even a year or dropping the product. The properly constructedsegmental wall will last a lifetime and advanced DIY crowd will find a rewarding and satisfying.
Before the construction, and even the design of the wall, there are several things to consider. You know the boundaries of your home? There are permits required? Are you physically for the challenge? It can operate equipment used for excavation? Some retaining wall units can weigh up to 80 pounds. Remove dirt with a shovel is nota trivial task for more than a few meters high walls, and replace them with wheelbarrow loads of gravel to hard work. Renting a vehicle for a weekend, like a skid steer loader, a wise investment. This article is not intended to discourage a segmental retaining wall construction, but to stimulate thought and planning. A segmental retaining wall can not be manufactured by just throwing a few blocks on the floor and stacking the rest of thecourses in the top, this is a recipe for failure.
The simplest option is the retaining wall. Gravity walls rely on their own weight and setback to keep the land behind them. Gravity walls are less than three meters long and have no type of grid reinforcement for stability. For this wall, cheap and easy to install, use a single block, which will be the least expensive.
Other considerations include:
Drainage: Waterinfiltration will be destroying a retaining wall from the inside out. walls are burnt due to the hydrostatic pressure that could not be repaid. All segmental retaining walls must be at least 12 cm of gravel behind the wall at any height. A cracked exhaust pipe should be installed after the basic course of the block. This should be channeled into the daylight to help reduce the water pressure behind the wall. Drainage Channelsmust be built on top of the wall to keep out water oriented.
Foundation: a segmental wall has a base of 6 inches of compacted gravel. A concrete base is not required for a segmental retaining wall. Walls segments are designed to flex with the seasonal cycles of earth and concrete rigid base only causes problems. If you know the area that have soft or wet soils, additional excavationrequired.
Compaction: Compaction is key to the success of the retaining wall segmental compacted. The ground should be. The gravel behind the wall should be solid and the ground about 3 meters behind the wall must be compacted. And 'better if it was a mechanical vibrating plate, but can be made with a hand tamper walls. The manufacturer must understand that the wall compaction behind the wallto create the structure, the blocks to become effective veneer.
