Routing water away from your basement structure is something crucial. Water and moisture are two evils that can lead to cracks and strength deterioration in the foundation. Weeping tiles are specialized perforated and corrugated drainage pipes that fundamentally re routes the water flow to the sump liner. While weeping tiles used for foundations are 4 inch weeping tiles, these might prove to be ineffective if the soil texture in your region is sandy or of a silt like texture. This is because these fine particles can enter the weeping tile and effectively block the path of drainage, there by forming a route which leads away from the sump liner and back to the foundation.
