About The Lawn Magnum
A problem plaguing property owners solved: surface water collected from extreme rain storms by run off of downspouts and basement discharge pumps now drains directly to roots of vegetation and the water table aquifer. No longer will water be relocated to other surface areas and cumulate into large ponds or overburden municipal sewer systems. Researches show that professionally managed lawn care and above ground water discharge pose no significant threat to the environment. However, the public perception is that all lawn care and above ground water discharge is a primary source of contamination and surface flooding.
Research and Development
Researchers challenged to come up with solutions that reduce the risks of lawn care and surface water discharge pollution and flooding have designed a sub surface drainage and deep root irrigation device (the Lawn Magnum®) to eliminate contamination and surface flooding allowing a highly efficient recycling of water and nutrients.
Lawn Magnum Specs
The Lawn Magnum®, with similar installations since 1952, has a life expectancy of approximately 50 years. The unit is 28” in height, 161/4” in diameter and weighs about 150 lbs. and is manufactured from an inert carbon material and portland cement. It is now available exclusively through your Basement Technologies® dealer and should help alleviate lawn flooding. The Lawn Magnum® is a patented design set up to force water laterally under the lawn, recharging the aquifer. The discharged water is forced downward into the Lawn Magnum® and dispersed laterally into the subsoil and the aquifer, thus reducing the hassle and inconvenience of huge excavation sites and heavy equipment use. For severe flooding, multiple units can be installed.

Exterior French drains are a realistic solution during construction. In fact, most new homes today do have an exterior french drain system. However, in a post-construction setting – when a water problem is diagnosed in a completed home – exterior French drains are not a realistic solution. With landscaping, decks and the necessity for heavy equipment to transverse the grounds, exterior French drains should be avoided once the house is built. Another negative factor is the fact that these systems can rarely be warrantied by legitimate companies.
Exterior French drains also tend to clog. During my tenure in the basement waterproofing industry, I have performed repairs at many homes with exterior french drains in place. The systems failed because of clogging with dirt. Although these systems can be wrapped with felt and back-filled with stone, dirt will still get into the stone and around the felt and can completely clog the system.
Another area of concern with exterior french drains is where the water should be drained. This can be a significant problem if the house is anywhere from 5’ to 8’ below grade and is running a pipe around the perimeter. This pipe needs to be pitched and dropped off to a point where the water may drain away. Some methods currently being used to accomplish this are dry wells, draining to a storm drain system or draining to an exterior or interior sump pump. These methods have the potential to be extremely unreliable.
The main reason that we do not recommend exterior french drains as a primary means of basement waterproofing is that they will clog. Catch basins and pits can fill up with water – supersaturating and causing back flow around the pipes – resulting in a bigger mess than you had before.
