Problems Experienced With Retaining Walls
Retainer walls serve a lot of purposes for
gardeners. They can "extend" the area of the garden, for
example, by providing additional space in the form of elevated
platforms. Also, they can allow gardeners to avoid the
problem of persistently bad soil by giving them the opportunity to
build a subspace within the space allotted which they can fill up
with good quality soil away from the unhealthy mound. Most
importantly, these walls can also beautify the landscape, what with
the sheer variety of designs made possible by their colors,
textures and shapes.
Building retainer walls, however, is not as easy
as it seems. There is a science behind the process, one that
has been perfected by years of experience and countless hours of
study. Building these walls has been classified under the
domain of structural engineering. Yes - engineering! If
you're like me and the term intimidates you, don't fret just
yet. Engineering can be as practical or as difficult as we
want it to be.
A lot of people encounter many problems in
building retainer walls. Let's take a look at some of these,
as well as discuss how we could best avoid them.
* Wall collapses. Bear in mind that your
wall will have to go against the weight of the mound it will be
supporting magnified by the force of gravity. If the wall is
not properly angled, it will always be in danger of
collapsing. The best way to avoid this is to make sure that
the wall is built in a way that it inclines towards the
mound. This way, it will go against the force of gravity and
enhance its resistance against the same.
* Blocks keep detaching. The problem here
would have to be the way the blocks are cemented together.
Blocks, especially the modular ones, usually have biters where the
cement should pass through. Once the cement hardens, the
blocks will have a better grip since the biters are sculpted for
such. Another possible cause for the problem is improper
cement mix. Too much water can affect the adhesiveness of the
cement.
* Blocks crack. Modular retaining walls
rarely have this problem. Chances are, you created your own
blocks. Mass density may be a possible cause, again, if too
much water was applied to the mixture. Also, temperature,
either above what is ideal or sudden changes thereto, can place too
much strain on the blocks and make them crack. The solution
is prospective. Before you create your blocks, study the
factors that will be at play so that you can take preventive
steps.
