The MOST COST EFFECTIVE
 PERMANENT SOLUTION

for Leaking Basements

This innovative system installation can
make existing weeping tiles obsolete.  

Millions of lineal feet of this type of 
system have been installed 
all over North America and Europe. 

Row Housing - Residential Basements 
Commercial Buildings - Apartment Buildings 
Walls Inaccessible by Excavation

No digging required.
$$$ Save Thousands of Dollars $$$

Even if the basement is finished, we can provide you with a permanent foundation drainage system you can count on. Most projects take between 
1 & 3 days, costing 25% to 50% less than traditional excavation style replacements.  Why replace something that will likely clog-up again? 
We are leaders for Interior Water Control Systems (IWCS)!

Perfectly engineered for block or poured concrete basements!

All installations are tailored or adapted to suite on site circumstances.
System features include automatic wall condensation collection and removal, partial or full perimeter systems available.
We can adapt these systems to function in a wide variety of configurations. 
Interior air gap membranes are very often used in conjunction with this system to eliminate or reduce moisture vapour penetration through foundation floors or walls.

Many concrete basement  floors are not constructed with a vapour barrier under them to stop the transmission of moisture into the basement airspace.  This will cause higher than normal moisture levels in the basement and increase condensation on anything cold.  This problem needs to be addressed by managing the humidity level with dehumidifiers and proper air circulation etc. or the installation of a new sub-floor which includes an air gap vapour barrier.  This sub-floor system will greatly reduce the moisture problem and give you a warm floor as well.

Systems can be installed in with 1/2" spruce plywood to accommodate carpet, or 5/8" T&G for special floor coverings.

Between Slab Drainage Systems

These highly effective systems are installed by our skilled crew using Air Gap Membrane technology when the existing basement floor was originally placed at too low of an elevation. e.g./ placed next to the footing rather than on top.

The result is a new flat floor which is insulated from the underlying slab providing  incredible warmth and dryness.

Air gap membrane sandwiched between two layers of concrete to provide a drainage layer. Variations of this system are designed to effectively eliminate water seepage through exposed rock intrusions found in many basements.

Concrete & Masonry Weather Protection

 

Water or solvent based solution of sodium methyl siliconate provides water repellency for brick, concrete, stucco, and block.  Designed to prevent water penetration yet allow the face to remain breathable.  Product finish is invisible
and paintable. Water repellency can 
last up to 9 years.   
Extends the life of infrastructure. saving $$$

This product will prevent that "rain soaked" look of buildings, and help prevent freeze thaw damage we commonly see.  It penetrates, crystallizes and becomes part of the material.

Lets the wall breathe.

My

Thank-You

I have developed and collected much of the content on this site to benefit the huge number of visitors from out side my geographic area. These viewers need help in making their own repairs or instruct others in making repairs.  I have provided this information free of charge because I believe it makes our society better for us all.

To date this information has been used by hundreds if not thousands of people all over North America. I hope I can continue to be of help and wish to thank all those who have sent kind notes (and even sometimes money) back to me describing how they found use of this site.

It is my hope that people will now begin to use the new Forums Section of this site. I have figured out how to build this section so I can provide a place where you can all start to talk to each other.

Please give it a try.
