Water and drainage issues can be caused by a number of factors. The best time to learn how your home and surrounding property drains is when it’s raining. Watch where the water goes and where it collects, and you may be able to see where drainage can be improved. Proper drainage makes sure that water flows away from your home. Water damage is a year-round threat to homeowners everywhere. If your home shows signs of moisture or water damage, it may be a sign you have a drainage problem. And since the drainage system is largely hidden from sight, this system is especially prone to problems. Ensuring proper site drainage is essential in reducing the risk of flooding, property damage, and soil erosion.

DRAINAGE SYSTEM

Water originates from three different sources: rain or snow, irrigation, and, more rarely, from underground. Water will always flow downhill unless some sort of mechanical or electrical device is introduced to divert the water away or towards a collection point. The purpose of a proper drainage system is to drain all moisture, surface and subterranean, away from your home and towards a municipal drainage system or natural waterway. Drainage systems, including storm drains, pipes, ditches and creeks, are designed to hold a specific amount of storm water and to protect homes from flooding by storing water on the streets at a safe level. In the right areas and in the right amounts, stormwater on your property can be good for your lawns and gardens, but too much water will cause flooding.

FEAR OF FLOODING

Flooding is a natural occurrence caused by heavy rain. If enough rain falls in a short amount of time, rivers, creeks, and streams overflow onto floodplains, which are designed by nature to flood. But if it rains hard enough or long enough, low-lying areas become at risk of flooding. Clogged drains can create localised flooding, which can result in damage to property, roads, landscapes, and stormwater infrastructure. To prevent flooding from blocked drainage systems, keep your streets and gutters free of leaves and debris.

THE RIGHT GRADE

When a home is built it must be graded to allow water to drain off the property. If this isn’t done properly and the water doesn’t drain as it should, this can result in standing water near the foundation. This can cause problems ranging from rotting wood frame to the shifting or deterioration of your home’s foundation over time. The ground around the home should slope away from the foundation. Roof downspouts should extend two metres away from the sides of the home and be angled to direct stormwater away from the foundation as well as your neighbour’s property. Always ensure that leaves and other debris do not block downspouts, ditches or storm drain inlets on your property.

You should never buy a house without first calling on a professional home inspector, who will know where to look for water damage and drainage problems. The earlier the water damage is identified the better and more affordably you can repair the damage before it gets out of hand. Expect repair costs to your drainage system to rise if you delay an inspection.
