SOLUTIONS TO BASEMENT PROBLEMS
Frequent flooding, severe cracks that seem to be getting worse,
bulging walls, and heaving floors are not do-it-yourself projects-they
call for the services of Sahara Waterproofing. Sahara Waterproofing
offers long-term warranties for the work they do-that is important
protection for you, even if it is initially more expensive.
waterproofing systems differ, but most include one or a combination
of the three approaches
INTERIOR DRAIN FIELD requires breaking through the basement floor,
digging down to the footings, and installing a second drain field.
An interior drain field works in much the same way as the channeling
system except that it runs under the floor. The installer excavates
around the basement slab's perimeter, drills weep holes at the base
of the walls, then lays perforated drainpipe in a bed of gravel.
The result is a drain field like the one outside the footing. The
pipe channels water to either a storm sewer or a sump pump.
more costly than a channeling system, an interior drain field can
handle far more water, an important consideration if your basement
suffers from a high water table, a clogged exterior drain field,
or heavy seepage.
If a spring or high water table is forcing water up from below
the slab, Sahara Waterproofing may recommend installing a sump
pump. A sump is a pit that collects underground or runoff water.
As the pit fills, a float activates the motor of a pump in the
pit. A one-way check valve ensures that water from outside won't
back up into the sump.
PUMP turns on automatically as its pit begins to fill with water.
It should be equipped with a warning device that signals when the
pump isn't working.
Excavating to the footing, coating the foundation or adding a vapor-retarding
membrane, and installing a new footing drain is the most costly
alternative, but it may be necessary if damage is extensive and
the wall also needs to be rebuilt.
DAMP-PROOFING is a last resort. Treatment may be roll-on or sprayed
in compounds, sheet membrane, or other measures
Most problems unique to basements are caused by water. The first
step in drying out a wet basement is to determine where the water
is coming from. Is condensation the culprit? Is water seeping in
from outside, or trickling through a crack in a wall or the floor?
Is a high water table trying to push your basement out of the ground?
As you investigate each of these problems, as described below, bear
in mind that the problem could be the result of a combination of
Condensation results from excess humidity, often from an internal
source such as a washing machine, unvented dryer, or basement shower.
It forms where warm moist air comes in contact with a significantly
cooler surface such as an exterior wall or a cold water pipe.
If moisture is collecting on the floor or on one wall near the floor,
it's probably seeping in from outside or up from under the floor.
Seepage usually occurs because water is forcing through an expansion
joint or through pores and hairline cracks in the foundation.
Often you can see water trickling down a basement wall or oozing
up through a crack in the floor. Most basement leaks result from
poor drainage, especially roof runoff, or a grading problem, aggravated
by cracks that result from the normal settling of the structure.
Walls that are extensively cracked need professional attention.

One of the most troublesome causes of a chronically damp basement
is a spring or high water table that pushes water up through the
floor under high pressure. This often shows up as a thin, almost
imperceptible film. An underground water problem requires professional
help. Call Sahara Waterproofing today.
