SYSTEMS/SERVICES

  All the custom systems and services provided by “A” Waterproofing & Drainage Inc. have been carefully designed, created, developed and perfected, by us, then installed by us. We are the most qualified waterproofing & drainage experts in Oregon, with over a quarter century of reliability, experience, dependability, and consistency. The systems along with the services we provide to our customers are designed to be “maintenance free.” One such innovation is a gravity flow system we have developed in order to permanently keep basements and crawlspaces completely dry year after year. Any  drainage system that relies on electricity, or a battery to operate is only as reliable as the device (sump pump) or the power it requires to work correctly. All the custom systems, services, products and the solutions we offer home owners and businesses all over the N.W. have been tested over time and continue to do as they were designed to. We know what we are doing and no one has done it better or more consistently than “A” Waterproofing & Drainage Inc. has over the last 25yrs. We are and remain Oregon’s leading experts in drying up wet basements & crawlspaces, repairing leaky foundations and structures that have begun to allow water to get inside your basements or the crawlspace area below your home.

BASEMENT WATEPROOFING AND DRAINAGE

  "A" Waterproofing & Drainage Inc. is one of the only waterproofing & drainage companies that specializes in providing both interior and exterior waterproofing & drainage systems. When it comes to basement waterproofing & drainage we know one size doesn’t fit everyone. With us, you will not be limited to only interior drainage systems and solutions. So you won’t find us steering you into the one and only option offered by our competitors. Installing a drainage system on the interior or exterior of a home or structure will depend on your particular type of water issue or leak? For example, a foundation that is leaking from or through the wall, can only be waterproofed or sealed correctly and permanantely from the exterior side. Prevent water damage before it comes through the concrete, not after it's gotten inside your home. That is draining the water leak using a interior vapor barrier, not sealing or waterprofing it. Which, if the foundation shows any signs of deterorating, should be avoided, as to not allow further errosion of wall material. 

All of the water collected or diverted away uses a gravity flow system (high to low pt. drain) that directs all the water to low points in the system, to the collection or discharge area. These are designed then installed by us to collect and then remove the water. Whenever possible and if at all practical, we always custom design our systems in a way that all water collected drains away or runs off on its own, naturally. Because no help is needed from an electrical powered device (sump pump), we refer to this system as "maintenance free." This system represents the very best and most reliable of our custom drainage systems, as it doesn’t require continued attention, electricity, or costs to maintain, service regularly, and operate. We are and remain Oregon’s leading experts in drying up wet basements & crawlspaces and in repairing leaky foundations and structures that have begun to allow water to get inside your basements or the crawlspace area below your home.

CRAWLSPACE DRAINAGE PAGE

We Install Custom Crawlspace Drainage Systems without sump pumps!

If you are having water problems due to standing water in the crawlspace area below your home. Causing you to problems passing the home inspections needed in order for it to sell. “A” Waterproofing & Drainage Inc. has the most reliable and dependable crawlspace drainage systems available. All of our systems and services come with a lifetime warranty that’s transferable with the sale of your property. We stand behind all our work with a 100% satisfaction guarantee, which also include passing home inspections. The rare cases where having to use a pump is unavoidable, deciding to use a sump pump should come as a last resort, not the first and sometimes only option offered to you by others. Our installation experts are trained and educated in designing collection systems using back water valves, one way check valves, catch basins, sumps and pump wells in such a way that volume and flow to and from pump, and discharge lines are reduced greatly. The amount of times your pump cycles become less frequent, helping pumps to turn on less, thus lasting much longer and operating much more efficient. Keep in mind, “A” Waterproofing & Drainage Inc. are leading the way, specializing in creating custom drainage systems that are designed and installed to remove and disperse the water collected by our systems in such a way that sump pumps are rarely used and seldom needed. Why in the world would any home owner or business decide to use a pump of any kind, along with the extra devices, if it were not absolutely necessary, when you can get our drainage systems that don't require the use of a pump for the same price and often less?

But, after all is said and done,  WE ARE A BASEMENT WATERPROOFING & DRAINAGE COMPANY, NOT A WATERPROOFING & SUMP PUMP COMPANY If  you don’t have time to do it right, how will you have the time to do it again?
When it pours, “We Reign”
