Water seepage in basement is a common occurrence nowadays. Constant
exposure to water could cause damage to the stability of the foundation as well
as the goods kept in the underground room. Also, the situation could lead to flooding
in the basement. Furthermore, water seeping into the basement could cause
damage to the walls and wooden items.
The situation could turn a dry & habitable underground space into
a leaky & wet basement. Also, a wet
& leaky basement could cause mosquito, mould and mildew infestation. Besides
that, the situation could, after a while, undermine the foundation.
Technique to
Tackle the Situation
Basement waterproofing is one of the most efficient techniques of
dealing with the aforementioned situation. The technique is useful in directing
the water from the exterior, thus, averting water seepage through cellar walls.
It makes and keeps the underground room dry all through the year.
Furthermore, there’re actually two methods to perform basement
waterproofing. It can be performed internally (within the cellar) as well
as externally (outside the cellar). Both methods and their procedures are described
below.
Internal Waterproofing
It is known as water management or control solution as it makes no
attempt to obstruct the water from getting into the cellar walls. Preferably,
it controls and changes the flow of water once it has got into the cellar
walls.
Also, in this method, the work is performed within the basement. Furthermore,
in this method, an internal drainage system is installed within the cellar. This
system draws water away that has already got into the cellar walls and sends it
through the weeping tiles that are installed around the foundation footings. The
weeping tiles are then connected to sump pit. They send the water from the
cellar to sump pit. Lastly, the water accumulated in the sump pit is pumped outside
the cellar by sump pump.
Furthermore, in this method, sealants are applied on the cellar walls
and floors with the objective to prevent water and moisture from getting seeped
into the cellar walls and floors. Also, the sealants prevent mould and mildew
growth. They avert moisture from seeping into the additional parts of the
property.
External Waterproofing
This method involves excavation of ground near the property. The
work is performed outside the basement. Also, this method is known as positive
side waterproofing as it takes care of the hydrostatic pressure and obstructs
the water from getting into the cellar.
In this method, waterproof bonding membranes or polymers are applied
on the exterior walls of the basement. Also, an exterior drainage system is
installed along with dimple board that prevents moisture (from outside) from getting
into the cellar and routes water into the weeping tiles.
In order to install the drainage system, a trench is dug around the periphery
of basement walls. The weeping tiles are actually perforated pipes that direct
water to storm drain. Lastly, the
excavated ground is backfilled and the region is graded in order to lead water
away from the foundation.
