Crawl Space & Basement Repair
Our Crawl Space & Basement Repair Products
If you are a contractor in need of reliable crawl space and basement repair products, Walder Foundation Products has you covered. We provide the best quality systems and solutions on the market and expert-level education for those looking to become certified installers.
Pro-Flow Waterproofing System
For basement projects that need protection from water intrusion, our Pro-Flow Waterproofing System has a zero-failure rate when properly installed. It’s available in customizable lengths for any job scale and doesn’t get clogged.
PROSEAL Vapor Barriers
Unlike standard crawl space encapsulation systems, our PROSEAL Vapor Barriers don’t use nails to install the protective liners. It is the only a system that truly provides a seal that moisture can’t permeate. Plus, these barriers install in half the time of other methods.
Dynamic Post Jack Support
Stronger than other leading crawl space jack support systems, the Dynamic Post Jack Support System goes deep into the soil instead of relying on heavy cement slabs that will eventually sink again. It’s fully adjustable, corrosion-resistant, and can stabilize up to 30,000 pounds.
Polybase
This lightweight polymer concrete foundation is glass fiber reinforced and 30% lighter than conventional concrete blocks. When used with our jack support system, the spreads the load more efficiently and provides the most substantial support available in the industry.
Aprilaire Dehumidifiers
Aprilaire is the most advanced and reliable dehumidifier brand on the market. With digital technology, a lifetime filter, and a 5-year warranty, it’s our top recommended solution for energy-efficient moisture control in any home.
Sump Pumps & Basins
Walder Foundation Products has a variety of heavy-duty sump pump and basin models that work with our Pro-Flow Waterproofing System to keep basements protected from water damage. We carry everything from battery-backup systems to check valves, and all our products are backed with warranties.
Crawl Space Access Doors
This Crawl Space Access Door is a unique design made from 100% PVC, so it won’t deteriorate or rot when exposed to moisture. The door operates on an innovative slot-and-lock system that doesn’t use hinges, ensuring that it stays durable for years.
YCS Vent Covers
Traditional vent cover methods use pieces of foam board that are less than successful. YCS Vent Covers are a simple yet highly effective product that can be custom-fit to any size vent. We carry two different styles of vent covers plus a patent-pending vent fan code-approved for continuous exhaust ventilation in crawl spaces.
WFP Vapor Barrier Tape
What makes the WFP Vapor Barrier System seal so much more effective than other methods is the WFP No-Nail Attachment Tape. The tape creates a permanent seal without drilling holes or using solvent-based adhesives.

With a large capacity, they hold plenty of debris or waste, helping you manage big tasks efficiently. A generous supply ensures you're well-equipped for multiple jobs.
