Water Proofing

exterior and interior basement waterproofing

Exterior and interior basement waterproofing are a vital part of the home’s structural integrity. Groundwater is one of the most important sources of moisture throughout the planet, and that moisture can do a lot of damage to the foundation of your home in the form of hydrostatic pressure. Hydrostatic pressure is the force that compresses the soil on the surface of your foundation, creating an impermeable barrier against groundwater. Waterproofing your foundation protects your home against that pressure, as well as from structural deterioration due to leaks.

Interior basement waterproofing is also necessary because it can reduce the amount of stress on your foundation. Prolonged standing water inside a basement causes the floor to expand and contract, which has an enormous effect on the structural framing around your foundation. That expansion and contraction cause cracks to appear in your foundation, which is a significant safety concern. Large cracks can compromise the integrity of the foundation or the framing around it. If the damage is not addressed right away, the cracks can spread and weaken the foundation over time.

Concrete is a good material to use for waterproofing because it is extremely durable. Concrete provides excellent resistance to hydrostatic pressure and contains tiny pores that make water evaporation difficult. If you combine concrete with a waterproof liner, you can greatly reduce the rate at which water infiltrates your foundation. Also, waterproofing does not affect the quality of the building materials used in your home’s construction, which is extremely important if you want your building materials to last a long time.

Unfortunately, exterior and interior basement waterproofing are not the only options for reducing foundation wall cracks. Severe weather can also cause cracks in your walls, so it is absolutely necessary to repair these problems as soon as possible. A leaky roof can contribute to water infiltration since it does not allow vapor to escape. Heavy rains can also cause damage to your home’s interior by damaging the wood framing and moisture can set in under the shingles on your roof.

Poor interior window well drains can also contribute to moisture buildup. The drainage system in the house removes excess moisture from the inside through the doors, windows, and skylights. If the window wells drain improperly, this liquid can seep into the base of the house and create foundation wall cracks. This can be avoided by installing well drains wherever possible. The most effective drainage systems are installed around the foundation, under the floor, around the garage, and in the exterior walls.

Exterior wall lining materials are another option to consider when dealing with water penetration. While many waterproofing contractors will suggest the use of concrete waterproof, this is a very expensive product that does little to prevent water from getting inside your walls. It is better to go with a non-permeable membrane such as gravel or an interlocking spray surface. These products do not contain sand and are therefore more affordable. They also work better in preventing frost heaves, because they can stop the water from flowing freely across your walls. In addition, they are more efficient at keeping the moisture out than concrete waterproofers.

Getting a damp basement is not probably one of the happiest of news possible. It is hard to locate moisture entry into a basement room and one of the most simple test is to tape a piece of aluminum foil to the inside of the walls in the basement and let it be there over night. If in the morning, there is a film of moisture accumulated on the foil, it demonstrates the presence of moisture or points to the need to take preventive steps to clear up the basement.

  1. Concrete sealants

These are typically additives to the concrete cement and brushed on to the walls along with slurry of concrete. They are rather simple to apply and it does not require much of a preparatory work either, it is even possible to brush on the slurry in the presence of a little moisture as well. But the key criterion is to have the mixture dry as fast as possible as it could have a strong bearing on the quality of seal that is formed on the mixture coating.

  1. Silicate based sealers

The silicate sealers are additives that are added to water to be brushed on to the walls outer layer. Most of the cracks and holes are sealed over by the silicate fibers which tend to create an impermeable coat over the surface. But unlike the concrete sealers, the silicate sealers can be used on surfaces that have been painted over and done to a finish. The time taken to affect a complete seal of the surface is much smaller in the case of silicate sealants.

  1. Acrylic paints

Commonly acrylic paints are seen to be used in practically most household paint works but in the case of water proofing, acrylic paints are used to form a sealant surface so that the moisture and dampness is kept out of the basement or other building parts. The main disadvantage of the acrylic paints is that it needs a completely dry surface to be applied to and takes a fair amount of time to dry out too.

If ever there were a strong point to using acrylic paints, then it has to be that there are many shades that are available in the market. Thus there is no dearth of choice and the ability to match the color to the needs of the situation.

  1. Sheets of barriers

The barrier here refers to the layers of plastic or acrylic or even metal that can be placed to prevent the ingress of water at best. Some of the barrier types are screwed onto the walls or even attached with a strong binder to prevent the seepage of water. When it comes to the actual effectiveness of the solutions, it is the quality of the binders that decide on the success of the final solution. It is here that metal sheets like aluminum come to play a strong role in the creation of the barriers.

Having a seeping basement could be one of the most distressing of experiences. Firstly, there is the issue of locating the ingress of the moisture and then comes the issue of having to isolate the seepage and turn out a dry building basement. The two actions are not complementary and needs to be tackled in a systematic manner that would ensure a complete and thorough dryness to be attained.

Dig around

When the seepage is first noticed in a building, the first step is to just dig around the area of the basement. This should expose the outer surface of the basement to the outside to make an assessment of the issue in greater detail. At times the issue could be so apparent that a simple visual perusal could turn out to be the solution that people are looking for. But instances such as these are not much and often it takes a little more of deep digging to bring into the open the issues that have been dormant in the construction. Furthermore, digging around is like an assessment that every team of tree services provider did to all aspects of their services and you can check one great example of this work preference through their website.

Applying the sealants

With water, it does not take much to create the seepage into a building. Just the tiniest of cracks is enough to set into motion the ingress of moisture. Many a times, the concrete cement could lose its cohesiveness to allow water to seep into room.

Sealants can be applied both ways, internally and externally as well. The final choice of the application is situational wise that takes into consideration the final layout of the room base. It really does not matter if the sealant is applied external to the room or internal to the space, but the greater issue of containing the ingress of moisture needs to be addressed adequately.

Another issue with sealants is that there are a number of types of sealants available in the market. The cement based ones, the epoxy ones, the polymer ones and so on.  Each type has its own individual style of application and curing process as well. Some are additives to paint and slurry while others are but stand alone mixtures that needs to be applied individually.

Using the membrane

The membrane is but an elastomeric coating that is applied to form a completely sealed in basement.  It can be applied to both the exterior and the interior of the building basements.  The strong point of the membrane is that it can smoothen over the cracks that occur later on with the shifting or movement of the structure at any time. The elastic polymer can be flexible enough to withstand mild tremors without breaking out the seal on the building.


Rather than use very exotic manner of application or method, it is the simplest application that would work longer and is durable too.  Treatment forms are but methods developed over time and further improvements in technology and their application is to be expected at all times. Increasingly, there has been a fair success to controlling the ingress of moisture to the basements and it is only natural that further improvements in the way solutions are applied are undertaken to the full extent.

People often think of having the basement worked when they do notice moisture accumulating at the bottom of the basement floor. But for all practical purposes, the moisture ingress into the basement can be classified as three separate causes. The internal, the external and the drainage.  It is when the issue is addressed in the right approach that the complete ingress of moisture and water into the basement gets to be controlled.

The internal drainage

By the very term, internal drainage, it signifies the seepage of water from sources that have their input from the interior of the houses or buildings. The first step is to find out the major flow source of the water and to try and block the path of the flow of water as best as possible. This can be affected by putty filling the cracks and to seal in the cracks with sealants for the most parts.

The final result must be that the basement floor must be free of moisture ingress from the interior of the house at anytime. Considering the complexity of the situation, it is never that the process of identifying the internal sources of water is going to be easy but most of the time it is a long drawn out process that needs time spend and effort expended.

External sources

At the first instance of keeping out external sources of water, the basement walls are coated with a waterproof compound so as to prevent the water from getting into the basement. This can be approached in two ways. The first is to apply sealant to the interior walls of the basement to keep out the water and the second is to remove the soil around the bottom of the building and to apply a sealant to the external surfaces.

The actual method of application depends on the situation of the repair work and never can be taken to be a rule as such. It is the thorough application of the sealant that decides how effective it is when it comes to keeping out the water.

Drainage systems

The basement normally forms the lowest part of any construction. Thus the final resting place or collection point of all drainage in a building gets to be the basement too. If there is a faulty design of drain pipes or of systems to contain the water within, then it would be reflected in the moisture or water ingress into the basement of the buildings.

With this sort of persistent drainage problem, the corrective step is to redo the drains from the scratch. The extra cost would be borne by years of trouble free service hence forth.  The thing with piece meal approach is that often sections would not match to each other and water would seep through the different joints that are thus formed at the pipes.

One of the features of drainage or seepage that has not been handled here has been that of condensate being formed on the walls, both the exterior and the interior as well. This effect must be taken into consideration when an actual basement work is being carried out.
