Frequently Asked Questions (FAQs)

What is a Channel drain?

This drain is installed along a driveway or patio for water to exit and discharge to an existing drainage system.

Why Sump Pump is needed?

Water flooding basement: A sump pump is needed. The pump keeps water/excess water out of the basement or crawlspace and sends water out and away from the property to a proposed exit area. It also helps to prevent the growth or spreading of mold. The size of the sump pump will vary, which will determine how efficiently it will keep up with rainwater.

Why Retaining walls is required?

Soil is shifting: A retaining wall is needed. They are built to prevent soil from shifting. They need to be strong enough to withhold soil and water. Bay Area Drainage offers various options for materials used for retaining walls.

What are french drains?

French drains are trenches filled with gravel or rock and contain a perforated pipe that captures surface or groundwater, diverting it away from the home. The trench serves as a channel for water to flow through the pipe, exiting at a location that will be determined during the consultation. Possible exits are the street, a culvert, a dry well, or other safe distance from the property.

What is an Underfloor Drainage Solution?

The drain takes water out of a crawlspace. It’s an alternative type of drainage that does not disrupt the exterior landscape. An Underfloor Drainage Solution is designed to remove water from under the crawl space after it has already intruded into the crawl space. If installed throughout the entire crawl space it can minimize the moisture under the home. An under-floor system generally consists of 3” perforated drain line with Class II perm drain rock. From this main line, there will be finger trenches and then the underfloor will be capped with a vapor barrier.
