The Consequences of Poor Drainage
Inadequate drainage can lead to severe problems for concrete structures. The porous nature of unsealed concrete allows water to infiltrate, causing erosion, cracks, and detachment of outer layers.
These issues not only compromise aesthetics but also pose significant structural risks, weakening foundations, frames, pillars, and roofs. Over time, this deterioration can endanger workers, residents, or visitors to the area.
Tips for Commercial Parking Lot Drainage
Commercial parking lots require careful consideration to manage water drainage effectively. Puddling and water flow issues can hinder access and usability. Creating a slight slope while maintaining a level surface is essential to ensure proper runoff.
Expert land surveyors play a crucial role in determining the appropriate slope, avoiding extremes that may hinder movement or create hazards. Additionally, incorporating drains or runoff channels away from regular foot traffic areas is advisable.
Special Considerations for Concrete Roof Slabs
Concrete roof slabs, often designed with a generally flat structure, demand even greater attention to drainage. It’s essential to avoid a 100% flat roof, which can lead to water pooling and potential roof collapse. Recommended minimum slopes of around 1/64 of an inch per foot help direct water towards gutters, scuppers, or sunk-in drains, which safely channel water away from the structure without disrupting the surroundings.
Emphasizing the Importance of Proper Drainage
Regardless of the concrete construction involved, proper water drainage is an indispensable part of the planning and building process. Neglecting this aspect can result in challenging and costly fixes once issues like water pooling or seepage arise. Water’s persistent erosion, from rain, snow melting, or humidity changes, poses a more significant threat to buildings than almost any other force on Earth. By prioritizing water drainage, commercial concrete projects can significantly reduce maintenance and repair needs and keep lifetime costs to a minimum.
