Question DetailsAsked on 10/14/2011

Anyone familiar with the Beaver Basement Waterproofing system? Does it work?

I need to waterproof my basement. It gets a small trickle of water coming from one foundation wall. The water trickles across the floor of the rest of the basement. Not what I would call a flood by any means. Basement waterproofing contractors have quoted me as much as $15,000 to install a drainage system under the concrete. I've heard that the Beaver system is much less expensive. Anyone have any experience with this?

A beaver is an old term for building a dam in front of the wall, Also was called a top cove system. Consisted of a metal or plastic coving glued to the basement floor and left open at the top. The top is very close to the basement wall. Before EPA the trick was to leave opening in the cove at the basement drain and chip a channel to the drain from the opening in the top cove system.. Beavers build dams hence the name. Can be very evvective and legal if you run water into a sump pump pit. Yes I ran several waterprooging companies in the 70's when this system was sold by a gentleman named Thrasher in Omaha,NE.

The Beaver system is a baseboard type system that is usually epoxy to the floor. These systems are unreliable compared to a interior drainage system such as Grate Drain. Grate drain is installed under the floor IN FRONT of the footer. DO NOT HIRE A COMPANY PROPOSING TO INSTALL A TOP OF THE FOOTER SYSTEM!!!!!! The interior pressure is not relieved with a on top of footer system and usually allows harmful soil gas and humidity to escape into the basement. The Grate Drain system is a "closed system"
Please research www.basement health.org as a great website. Contractors on that website are recognized by the NAWSRC. (national association of waterproof and structural repair contractors)


If you are only getting some seepage, have a NAWSRC contractor install a sump pump only as a start. That will remedy the water pressure under the foundation and has a good chance of working. If you have a sump pump, make sure it is professionally installed. I HIGHLY RECOMMEND A GRATE SUMP (search Grate sump pumps) as they allow much more water to get to the pump. The Grate Drain system is very modular, if the pump alone didn't work, they could add some Grate Drainage along the perimeter to relieve some pressure.

Basement companies LOVE to sell you a full system but because the fact that the system is modular, you can use a cautious approach.

Remember, cheaper isn't better when it comes to foundation work.

We had a similar issue and hired a professional engineer to come out and evaluate it. This was only $350. Like, you, we had several companies trying to sell us on digging trenches in our floor and then putting in a sump pump, all at tremendous expense. The professional engineer told us all that was very unnecessary. He advised us to simply make it so the downspouts would get the water further away. I did the work myself with some exterior grade pvc piping and viola! No more water coming in at all. I think I did everything for about $100 and my own labor. Most of it took only maybe 4 hours.


We don't know your exact situation but if you have a downspout from your roof drainage over there, then make it so that all that water gets AWAY from your house, at least to the point where the ground will continue to slope away and you'll be set. Fix the root cause, if at all possible, instead of trying to deal with the water that will force it's way in, if allowed to sit against your foundation.
