SHOULD I PUT DAMPPROOFING OR WATERPROOFING ON MY
When building or
buying a newly constructed home ALWAYS
insist that contractor use a waterproofing
material on the exterior foundation walls.
Although these two products may look very
similar, they are VERY DIFFERENT in how they
perform. Many contractors continue to use
dampproofing because once the foundation is
backfilled the area is “out of sight, out of
mind”, and once the house is finished and sold
it becomes the homeowner’s problem if the
foundation starts to leak. The small amount of
money you save by not using proper waterproofing
when the home is built, can cost you a lot of
money to fix when water appears in your basement
after one or two years, or even sooner.
WHAT IS DAMPPROOFING?
products are typically a tar based material cut
back with a solvent based product. They are
cheap to apply and their effectiveness is
extremely limited because they are only to
designed to ‘retard’ moisture penetration, not
prevent it. The main problem with this type of
product is that it becomes brittle once it cures
and as the foundation settles and hairline
cracks appear, the tar based coating will not
stretch to bridge the cracks and this allows
moisture to penetrate into the basement. Many
homeowners who have problems with a wet basement
and dig up the exterior foundation find that
these tar based products have started to flake
off the wall within a few years of being
WHAT IS WATERPROOFING?
products are designed to “prevent” water
penetration even under wet conditions such as
hydrostatic pressure in the soil after heavy
rain storms or spring thaws. Advanced
Waterproofing Technologies products contain
rubber which provides superior waterproofing
protection and allows the product to remain
flexible even when it dries. This flexibility
allows the waterproofing membrane to stretch as
the foundation settles and bridge small hairline
settlement cracks that can occur in the concrete
WHAT PRODUCTS DOES AQUASEAL OFFER FOR EXTERIOR
Waterproofing Technologies distributes liquid
applied, exterior waterproofing products for use
on concrete or block foundations, or insulated
concrete forms (ICF). These environmentally
friendly products are safe and easy for the
homeowner or contractor to use and provide
superior waterproofing protection.
water based, liquid rubber membrane
All Season Formula
– heavy duty protective film
– dimpled drainage/protection board
WHERE CAN YOUR PRODUCTS BE USED?
waterproofing products can be used on
residential homes or commercial buildings. They
are designed for standard concrete or block
foundations, or for use with insulated concrete
forms (ICF). Also, some of the products can be
used on other materials that require a
waterproof seal such as wood, metal, plastic,
etc., or below interior surfaces such as the
floor slab or under tiles in showers, bathrooms,
etc. where moisture might be a problem.
OUR HOME IS IN AN AREA WITH A HIGH WATER
TABLE, WHAT DO YOU RECOMMEND?
In this type of
situation your foundation is under increased
attack from hydrostatic pressure so it is very
important to do everything you can to alleviate
the stress on your foundation walls. The best
method for doing this is to install a drainage
board such as our
Aqua-Board over the top of the rubber
waterproofing membrane. These boards are
actually plastic sheets with extruded dimples
that provide an air barrier between the
foundation and the backfill material to relieve
the hydrostatic pressure against the walls.
These dimples also create drainage channels so
that the water surrounding your property can
drain down the wall and into the footing drains.
HOW DO I APPLY YOUR PRODUCTS?
All of the
products we distribute are safe and easy to
apply by the ‘do-it-yourselfer’ building their
own home or the professional contractor. The
products come ready to use in 5 gallon pails or
55 gallon drums and do not require heating or
special application equipment – anyone who can
use a brush or roller can apply them. Or
alternatively, you can use a commercial airless
sprayer which can be rented by the day. An
average size foundation of approximately 1,000
square feet can easily be waterproofed by a
couple of people using a roller in 2-3 hours.
IS THERE A WARRANTY WITH YOUR PRODUCTS?
We offer a
30 year warranty
against product failure on all of our exterior
waterproofing products. Providing the
foundation is sound, all tie-holes have been
properly filled, and the waterproofing applied
to the correct thickness, the membrane will last
indefinitely – it will not dry out, crack or
peel off the wall. Our products are
manufactured with top quality ingredients and
you get some of the best products on the market
– we wouldn’t offer a 30 year warranty if the
products did not perform.
IS YOUR WATERPROOFING EXPENSIVE?
No, you will
find that our pricing compares very favorable
with other similar quality products on the
market, and because our products are ‘user
friendly’ you can actually save money by doing
the waterproofing yourself. Aquaseal products
will give you quality waterproofing for your
home at a price that provides very good value
for your money, and you will have peace of mind
knowing that your home is protected.
ARE YOUR PRODUCTS JUST FOR NEW CONSTRUCTION?
No – they can be
used for renovation projects, or by people who
have dug up around their exterior foundation to
fix a problem with a leaky basement. Once the
existing foundation is exposed clean it by power
washing to remove any loose debris. If there is
old waterproofing on the foundation, such as
dried-out tar based dampproofing products, it is
not necessary to remove this. Just clean off
any areas that are loose or flaking with either
the power washer or by hand, repair any cracks
or voids in the walls, and then apply
waterproofing right over the old material.
DO I NEED TO USE ANYTHING ELSE ON TOP OF THE
If your home is
in an area with well draining soil and you have
good quality backfill material, then you can
carefully backfill directly against our
products. However, if your backfill material
contains rocks or stones that could damage the
newly applied rubber membrane, then we recommend
the use of a product such as our
6mil polyethylene sheeting is highly puncture
and tear resistant and will prevent rocks from
puncturing the waterproofing.
You can also use
polystyrene boards against the exterior
foundation for their insulation value. Because
our products are water based and do not contain
solvents, they are safe to use with polystyrene.
with your local building department before
backfilling because some municipalities do
require the use of protection or insulation
boards in addition to waterproofing or
DO YOU HAVE ANY PRODUCTS TO FIX
A LEAKY BASEMENT FROM THE INSIDE?
We have a range
of products to seal your basement walls and
floor, prevent mold and mildew growth, and take
that musty smell out of your house. For poured
concrete foundations and block we have

soaking through to the inside – it has been
tested to depths of 400+ feet! If your walls
are brick or stone and mortar,
provides the toughest waterproof coating on the
market and leaves a clean white finish. These
commercial grade products are safe and easy for
the homeowner to apply and are an economical
alternative to expensive contractor repairs.
CAN YOU FIX THE MUSTY SMELL IN MY BASEMENT?
This musty smell
is a sign of dampness, even if your basement
doesn’t seem to have a problem with leaks. This
smell is caused by mold growth in damp areas and
fungus spores in the air, and this can
contribute to health problems such as allergies
and asthma. Advanced Waterproofing Technologies
basement waterproofing products will seal the
walls and floor of your basement and make the
air healthy and fresh again.
WHAT IS THE WHITE POWDERY SUBSTANCE ON MY
This is known as
“efflorescence” and is a sign of dampness in
concrete walls. The moisture is causing a
chemical breakdown of the bonding agent in the
concrete and the free lime is leaching out of
the wall. If this problem is ignored it will
eventually start to weaken the concrete and
compromise the structural integrity of the
wall. The powdery substance can be washed or
brushed off the wall and then the entire area
can be sealed with either
I HAVE CRACKS IN
MY WALLS AND FLOOR THAT LEAK WATER AFTER HEAVY
RAIN, CAN I JUST REPAIR THESE?
important to repair the cracks to stop the water
coming through to the inside, you need to then
seal the entire wall or floor surface with one
of our basement waterproofing products.
Remember that you only repair the interior part
of the crack – it still goes right through to
the exterior and will let water in. If you
don’t seal the surrounding wall or floor surface
the incoming water will by-pass the repaired
crack and soak into the concrete around it. The
resulting hydrostatic pressure can also cause
additional cracks to appear, branching off the
repaired crack – so you are only exchanging one
problem for another.
I HAVE PAINT ON
THE WALL, DO I HAVE TO REMOVE IT?
the answer to this question is YES. Existing
paint or coatings on the wall will stop our
waterproofing products from working properly.

do this if there is a barrier of paint in the
AQUA-BLOCK BB is a coating, it has
special ingredients that allow it to form a very
strong bond with concrete, brick or stone and
this adhesive bond would be severely compromised
by an existing coating. The existing paint or
coating can be removed with a good quality paint
stripper and any remaining residue can be ground
off using a mechanical wire brush. If you don’t
take the time to do this, our basement
waterproofing products will not work and you
won’t get the results you want or paid for.
