Basement WaterproofingBasement waterproofing entails the use of various construction techniques to prevent ground water from seeping into a building. This is particularly important for any structure built below ground level or at ground level. There are three main ways of waterproofing a basement: interior waterproofing, exterior waterproofing, and installing interior wall and floor sealers.
Interior Basement WaterproofingThe majority of interior water drainage systems work by draining underground water underneath the basement floor and alongside foundation footers. For instance, you can waterproof your basement from the inside by installing interior drain tiles. It is worth noting that these are not real tiles but perforated plastic pipes that building contractors usually bury beneath basement floors and next to foundation footings. To install these tiles, a building contractor removes about 12 inches of concrete flooring around the inside perimeter of a basement. After this, the contractor digs a trench that goes all the way to the foundation footing and then lays a bed of washed gravel throughout the trench. After doing this, the contractor lays perforated pipes wrapped in "filtration fabric" around the basement connected to a sump pump. Before pouring concrete to cover the drain tiles, the contractor may add more washed gravel. With such drain tiles in place, underground water will seep into them and flow to the sump pump instead of seeping into the basement.
Exterior Basement WaterproofingYou can hire a professional to install an exterior waterproof membrane to prevent water from seeping into your home's basement. In general, such a membrane consists of asphalt modified urethane that completely seals foundation walls. Building contractors usually cover waterproof membranes with heavy duty plastic drainage boards to help channel water away from the foundation of a building. Exterior drain tiles offer another effective way to waterproof a basement. These tiles function in the same way as interior drain tiles. However, contractors lay exterior drain tiles around the outer perimeter of a building's foundation.
Interior Wall and Floor SealersIf you do not fancy digging trenches for laying drainpipes inside or outside the foundation of your home, you could opt for interior wall and floor sealers. Waterproofing sealers are chemically formulated mixes. After application, these mixes create insulating layers that are impermeable to water. It is worth noting that these mixes are available in different forms including spray on sealers and paint on sealers. In summary, unless you have the necessary skillset, you should probably hire a building contractor to waterproof your basement. Depending on the location of your home and soil topology, your contractor could install interior or exterior pipes to waterproof your basement as well as prevent cove seepage.
