We are a leading basement contractor in New Jersey and Eastern Pennsylvania

Down Under Waterproofing was in incorporated in 2006 by Walter Gural. We came up with the name Down Under Waterproofing because we are literally, "DOWN UNDER" the house or building. We realize many home and business owners have researched different methodologies and we differentiate ourselves from others by listening to our customers. We will only then make a recommendation. Our ability to make realistic and reasonable recommendations is through experience - hours upon hours of jack hammering, installing carbon fiber, laying block or brick, installing sump pumps, french drains, encapsulating crawl spaces, troweling concrete, etc.

Since our inauguration in 2006, we have evaluated several products and manufacturers and have chosen the ones that are backed and supported by the manufacturer. Much of our success has revolved around manufacturers like Fortress Stabilization for foundation repairs (we are a certified installer), Liberty Sump Pumps, and Tremco drainage board, to name just a few.

Let's face it, "Father Time" eventually crepes into our buildings and homes. Sometimes, faulty construction is a problem. Down Under Waterproofing is often asked, "Why did the builder do it like this or like that?". My response is usually simply, "I do not know, the building codes may have changed but I know I can fix it".

Down Under Waterproofing & Structural Repair has you covered. Whether it is because of water intrusion or structurally, we have been there and done that. Our services provide fixing the foundation from repair to rebuild; waterproofing from French drains to encapsulation; removing wood sill plates to replacing them; lifting the house to install new block concrete walls; we install columns to support girders and joists; we remove old stucco and replace with new; we underpin so your foundation does not sag; and we rebuild your old retaining wall. Down Under Waterproofing can also rip out and put back sheetrock, bathrooms, etc so you do not have to call in another contractor.

Most of our work requires a licensed engineer (PE) and permits. We do not cut corners and we are trained by our manufacturers so we are certified to use their products.
