Foundation is the most important part of any structure, whether it is used for residential or commercial purpose. Foundation is on what the entire structure is built on and the overall quality and life of the structure will largely depend on construction quality of the foundation. It is advisable only to rely on the best exterior foundation waterproofing systems that often use sump pump to keep the basement dry and clean.
Before we talk about the different waterproofing systems that are available in the market today, let us look at the most common causes of water seepage in basement. It is a known phenomenon that the soil expands when it absorbs water though the extent of expansion varies with type of soil. For example, sandy soil allows water to pass through and absorbs very less while clay soil absorbs lot more water. More the absorption more the expansion of the soil takes place. This expansion creates pressure on the outer surface of the building and as a result water is pushed through any crack, unsealed opening or porous spot to cause seepage in basement.
Due to advancement of technology, basement seepage can be controlled or fixed by various methods. Broadly speaking they can be done either from the inside of the building or from the outside. Interior drain tiles have become quite popular that prevents seepage from the cracks and through the joint of floor and the walls. Water gets accumulated in a sump basin and then pumped out by a sump pump. Also, one can inject expanding polyurethane seals into the cracks which also prevent seepage.
Though the waterproofing from interior of the building is less troublesome and not time consuming, it is definitely much better option to go for the best exterior foundation waterproofing systems. This is because, the source of the water is from the outside of the building and fixing any problem from its source is always advisable. In the beginning of the process, excavation is done to expose the outer surface of the wall for further treatment. The surface is then cleaned and a thick coating of asphalt-modified polyurethane is applied by masonry trowels. Once the coating gets cured it forms an impermeable layer that prevents the water to seep through. Most of the times, a heavy-duty drainage board is applied over the layer which provides additional protection to the membrane and also helps to create a channel for the water to flow downward. If the water surrounding is quite high, it is advisable to install exterior drain tiles additionally to reduce the pressure on the wall significantly.
Since sump pump is the most vital component of any basement waterproofing system, it is extremely important to choose the right kind of pump. The success of the waterproofing system will largely depend on the size, power and the specification of the pump. Installing the best exterior foundation waterproofing systems is a highly technical job and a lot will depend on the condition of the structure and presence of water around the structure. Depending on the various conditions, the solution may need to be customized accordingly. For this reason, it would be the right decision to engage professionals for this job and you can be sure of the quality of work.
