Down Under Waterproofing

04/26/2026

Another project underway in Crosswicks, NJ 👇

We’re currently building a new 400 sq ft foundation and crawlspace for a home addition, and things are moving along nicely.

So far we’ve:
✔️ Excavated the entire area
✔️ Poured reinforced concrete footings
✔️ Installed rebar tying into the existing structure
✔️ Built the new block foundation
✔️ Waterproofed both the interior and exterior

All work is fully permitted and inspected to meet local building codes — making sure this foundation is built to last.

We’ll be sharing final photos once everything is complete next week.

If you’re planning an addition or dealing with foundation or water issues in Crosswicks or surrounding NJ areas, feel free to reach out 👍

We’ve been seeing more of this lately in older homes—brick walls starting to bow outward.

A lot of times it’s not just age. It usually comes down to moisture getting in over time and weakening the structure behind the wall.

We recently worked on a property where the floor dropped over 3 inches—and that movement started pushing the exterior wall outward.

If you’re noticing:

cracks in brick or mortar
walls that don’t look straight
doors or windows sticking

…it’s worth taking a closer look early.

We put together a more detailed breakdown of what causes this and how it’s repaired here:

🚨 NJ & PA Homeowners — Spring is when basements FAIL the most

Most people think winter is the problem… it’s not.

Spring brings:
💧 Heavy rain
❄️ Snowmelt
🌱 Expanding soil

That combination creates pressure against your foundation — and that’s when cracks, leaks, and water intrusion start.

⚠️ Signs to watch for:
• Musty basement smell
• White powder on walls
• Cracks in foundation
• Doors sticking or shifting

We broke it all down here 👇
https://www.duwaterproofing.com/blogs/post/why-spring-is-the-most-dangerous-season-for-nj-and-pa-basements

If you’re seeing any of these, it’s better to catch it early before it turns into a major repair.
