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.
