Basement Waterproofing Hazards

Select Reputable Contractor

Basement Waterproofing | AquaGuard Botches French Drain

The interior drainage system that AquaGuard Waterproofing Corporation touted as the solution to our basement waterproofing needs was utterly useless.  Every major part of the system, and many of the minor ones, are either defective, undersized, improperly installed, or some combination of these.  Such unworkmanlike performance might have been avoided if AquaGuard had exercised any direct supervision of their subcontractor.  Instead of a basement “…waterproofed with uncompromising pride, integrity, and value for life” as touted on their website, we were left with disaster upon disaster and more than $50,000 in contract-related damages.

In this and upcoming postings I will describe their failures to deliver the goods and services described by their so-called Senior Inspector during the inducement to sign the contract.  Details of AquaGuard’s “Water Management System” are contained in their proposal but, as we have seen (See Posting Misleading Proposal), AquaGuard doesn’t feel bound to abide by those details.  Regardless, all expert witnesses who testified during the arbitration process agreed as to what was appropriate for such a system.  Only the subcontractor AquaGuard hired, based on the work performed, seemed to think otherwise.  Either that or he was simply intent on ripping me off.

Here are quotes from the proposal (See Proposal:  AquaGuard Water Management System for complete text):

“The existing concrete floor edge is to be removed approximately 12-18 inches out from the adjacent edge of the wall(s), along the perimeter of the basement.  All sub-floor base material (clay, gravel and any outdated drainage piping) will be removed to clear a clean, sloped trench path along the inner side of the footer.  In the trench path, AquaGuard will install 4 inch Advanced Drainage System perforated, flexible coiled piping in a bed of large washed gravel, sloped 1 inch for every 10 feet for proper drainage.  This drainage piping will empty into a 30″ sub-floor, commercial grade plastic container housing a heavy-duty submersible 1/2 horsepower pump.  Water from the pump will discharge via a 1 1/4 inch PVC piping above ground and allowed to fun off as surface water”.

For now note that just about the only part of the above that was actually done as described was the use of the 1 1/4 inch PVC piping to allow seepage water to be discharged from the basement.  The piping itself was poorly assembled and installed.  Indeed at least one of the joints leaks.

Continuing with the proposal:  “Lower wall facings below the floor slab are to be exposed and cleaned of any silt.  The crew will treat the “key area” with the Aquaflow key channel water management system along the lower facing and adjacent to the floor edge.  This drainage composite will serve as an expansion joint to ensure proper channeling of water beneath the floor and serve as a back-up system for water seepage through the wall”.

There will be much more to say about this “drainage composite” in a future posting.  For now, observe in the above diagram that the “Miradrain”was supposed to go from well above the floor slab and into the “large washed gravel” at a right-angle (left diagram).  In reality it was short-cut (literally), poorly installed, and stuck into the dirt instead of being channeled through the gravel within the drainage path.

Finally there is the curious case of the missing vapor barrier.  As stated in the proposal and described by the “Senior Inspector” (though strongly denied by the General Manger…):  “A cover of 6 mil polyethylene will be used as a vapor barrier between the Aqua Guard Mira drain and the floor slab.  The crew will then complete the job by hand troweling a cement replacement over the trench using a Portland cement mis.  All job related debris will be removed, hauled away and the serviced area will be left broom cleaned.”  We will examine what really happened in future postings, including the testimony of the expert witnesses and the remarks of AquaGuard’s General Manger.

As the Arbitrator summarized it (See Award – Final – Rzemien v AquaGuard):  “The subcontractor did a terrible, terrible job” and “The Owner timely notified Contractor of the problems with the work, and the Owner offered Contractor ample and reasonable opportunities to come to the house and present a remedial plan.  However, Contractor did not take advantage of these opportunities, insisting instead on having its incompetent Subcontractor return to make repairs.  The Contractor failed to take diligent, timely and reasonable steps to cure the defective work.”

“…uncompromising pride, integrity, and value for life”?  Buyer Beware!

    I think it is interesting how much of a difference these drainage systems work. I would love to have something like this for my home. It could really save my home if there was ever a really big storm that came up.
