What Are Drain Tiles And What Are Their Functions?

A drain tile system serves to collect and divert water leaks from the home. Drainage panels can be placed both on the inside perimeter of the foundation and outside when building a house.

Drainage tiles mainly consist of a perforated pipe placed in a trench and covered with gravel. Some contractors cover the pipe with nylon filter socks to prevent the pipe from filling with debris. Typically, water entering the pipe is then diverted by gravity to the sump pump or away from the base. Typically, experts are hired for perimeter drain tile installation services.

Most drainage panel systems are based on the same concept. The difference lies in the material, the shape of the panel, and its location.

Manufacturers have designed drainage tile pipes in a variety of shapes, from round, rectangular, and square to elongated variants or ventilation tubes with multiple openings to increase flow.

Internal Drainage Tiles

The internal drainage tile system can be placed under the concrete slab. To install this option, a portion of the basement floor is removed (about 12-24 inches from the concrete floor). Then a trench is dug and the pipe is laid and covered with washed gravel. Typically, contractors install a waterproofing product to direct water entering through the foundation to the drainage slab.

External Drainage Panel

External drainage panels, more commonly known as foundation gutters, are usually installed during construction. The drainage board around the outside of the base acts as a tube system to collect and divert groundwater that flows into and through the soil.

Installing an external drainage system in an existing building is the least expensive but also the most effective approach to water control.
