When it Pours, we Reign!


“A” Waterproofing & Drainage Inc.  a locally owned and family-operated small business proudly serving the Greater Portland/Metro area for over 40 years. We are a licensed, bonded and insured basement waterproofing & drainage company, a member of Oregon’s C.C.B. #209016

We specialize in all types of wet basement waterproofing & drainage systems and services, and all types of basement waterproofing & drainage repairs to ensure your home remains dry, safe, and structurally sound. Due to Portland’s frequent and consistent rainfall, protecting your home or business from water damage is essential

We are one of the few basement waterproofing & drainage contractors that provide both interior and exterior methods or systems to permanently dry up any wet basement or crawlspace. We don’t agree with a one-size-fits-all approach when waterproofing that other (interior only) waterproofing companies will do their very best to try and sell you. A leaking foundation wall can’t be waterproofed and sealed from the interior. Just the same as a wet crawlspace can’t be dried up and waterproofed from the exterior. If anyone or any waterproofing company tells you differently. They are wrong and don’t know enough about waterproofing and drainage. Period! We custom design, build, and then install our own custom drainage systems. We won’t ever try to sell you their “so-called” patented and inferior basement waterproofing systems, services, or products. These gadgets they provide are someone else’s waterproofing systems, ideas, and special drainage pipes, (a waterproofing franchise of some sort) selling, installing, and guarantying someone else’s systems and products.

Products such as their special, patented drainage pipes, are designed to have a short section of the pipe sticking up above the floor and up onto the foundation wall or a dimple board /matting used to create a gap or space where the floor meets the wall. Allowing the water to continue to leak in and run down the interior side of your wall. The water allowed to continue to leak in will run down the inside of your wall then down into the gap made by their patented pipe and installed below the basement floor. Because now the basement concrete floor doesn’t meet and touch their foundation walls, to form a tight seal. Using their interior drainage system method does not seal the foundation walls from the exterior, stopping any water before the water gets inside the foundation walls. Only after, allowing the water inside, to then be diverted or pumped back to the exterior.


Their patented special pipe that you see is actually square, designed to sit right on top of the foundation's footing. A footing must be completely level or flat. The basement concrete floor rests on that footing for support, to stop possible settling. So their special drainage pipe, if you notice. Sits atop the level footing therefore having little to no grade or slope on their drainage pipe for the water to collect and drain away. I wonder now, how is the basement floor going to sit or rest on the footing for support when their special pipe is installed on top of it? (For the pipe to be at the correct depth and grade, and to work correctly. The pipe should be installed beside the footing with fall on the pipe, not sitting flat on top of it) The only thing special thing about their pipe is being flat on the bottom. The only drainage pipes we have ever seen or used have been round. That would answer the questions. Why is their pipe square, with a section going up and shaped like the letter d or b, depending on how you are looking at it. This is not waterproofing, it’s draining the water still leaking in, using a much higher-priced floor system to drain a foundation wall that is leaking. Never actually stopping the leak at all. 

Then when customers complain they do the ole pass-the-buck routine, not taking any responsibility while deferring you to the waterproofing outfit where they got the systems from. We believe whomever we hand our money over to, is the one who should be responsible when a problem exists. We continue to stand behind all our products and services with a lifetime warranty, covered by our 100% customer satisfaction. We have well over 10,000 satisfied and valued customers locally, gaining more with every wet basement, crawlspace, or home we dry up. Proving over and over "A" Waterproofing & Drainage Inc. is a company you can count on and trust for years to come. We are the best at what we do and no one does it better. Our reputation as the #1 basement waterproofing experts rests on our proven ability to consistently and permanently solve every wet basement & crawlspace drainage issue we encounter when the others continue to fail. We are an honest, ethical, and responsible business owner. 

You won’t ever find us using pressure sales or scare tactics like others do when offering any of our services and products to our customers. You will never find us trying to direct you toward our one and only interior method for solving your waterproofing & drainage issues. We know from decades of experience in the Portland/Metro area that one single method of waterproofing homes and businesses will not and can’t solve or fix every type of water problem. We let our company's good name, work ethic, and spotless reputation speak for itself. Or if you prefer you can always ask our countless and vast list of satisfied clients that have continued to remain dry from our waterproofing & drainage services and products. That has everything to do with not attempting to try and offer a one-size-fits-all approach to waterproofing. It has been proven again, time after time that it is impossible to waterproof and permanently dry up every wet basement or crawlspace using the interior (only) approach to solving Portland’s wet basement troubles. If it were successful, don’t you think we would be doing just that? It won’t, so we don’t and therefore never will. Because our customers and reputation matter to us and to you.

 EXPERTISE

We have over 40 years of knowledge and experience accurately diagnosing and then custom designing and installing our own custom waterproofing & drainage systems we build just for your home or business to permanently dry up your wet basement or remove any standing water in your crawlspace. We guarantee to pass your home’s inspection. We have never failed to pass a home inspection.

COMPREHENSIVE SERVICES

We offer a full range of waterproofing & drainage services and systems, both interior and exterior methods. We are not one of the one-size-fits-all types of waterproofing contractors. A basement floor leak and a basement wall leak are both two separate water issues, with two separate causes for the leaking. A single method for waterproofing and permanently keeping your home dry and safe will not solve both types of leaks you may experience. When it comes to drying up wet basements & crawlspaces, the suggestion of a single system killing two birds with only one stone, won’t work to solve every type of water leak. If it were that simple, don’t you think everyone would be doing it? Our hard work and knowledge is there to assure you not only a dry, safe, and healthy home for years to come but also peace of mind knowing your water troubles are a thing of the past.

HIGHEST-QUALITY MATERIALS

We always use the latest technology combined with the highest quality materials. To ensure our custom waterproofing & drainage systems continue to out sell and out preform all the others while proving over and over one size doesn’t fit everyone. Our company’s dependability is built from decades of consistency in drying up any wet basement or crawlspace in the greater Portland/Metro area when the others fail. No one has continued to do it better year after year. We know basement waterproofing, that’s what we do!

We want our customers to feel glad they chose “A” Waterproofing & Drainage Inc. for all their waterproofing and drainage needs. We won’t settle for simply satisfying homeowners, we go the extra mile, hoping to leave them more than just satisfied and if not, we find out what can be done to change that. A good word will travel a very long way for a business, but nowhere near as far as a bad one will. 

COMPETITIVE PRICING

We offer superior services at a fair and honest price. We will never use any scare tactics or pressure our customers to make a rushed or uneducated decision. Be very leery when others try to? Transparent and upfront pricing and competitive rates. Without compromising on quality or workmanship. No one does it better, at any price. Come and see for yourself. 

“A” Waterproofing & Drainage Inc. challenges our readers to do a little research on the activities at the once believed highly regarded Better Business Bureau (BBB) and their faulty grading system. How accurate and honest can a referral really be, if you have to pay for it? And more importantly how much integrity can the BBB have? When for a monthly fee they will knowingly give the unsuspecting public an excellent reference for one of their paying customers, knowing darn well that their client is anything but. The BBB is not a state-run or state-backed organization. They are so far from being a non-profit organization, thought to be there to protect the public from fraud.
