How to Maintain Your Waterproofing System: A Property Owner's Guide

A quality waterproofing system is an investment that protects your property for decades — but only with proper maintenance. Here's our guide:

Annual Inspection Checklist

Exterior

• [ ] Check roof membrane for tears, blisters, or punctures
• [ ] Inspect flashing and sealants around penetrations
• [ ] Clear gutters and drainage systems
• [ ] Check expansion joints for separation

Interior

• [ ] Look for water stains on ceilings and walls
• [ ] Check basement walls for moisture
• [ ] Inspect window and door seals
• [ ] Monitor humidity levels

Preventive Maintenance Tips

1. Keep Drains Clear

Clogged drains cause water pooling, which accelerates membrane deterioration. Clean drains quarterly.

2. Trim Overhanging Trees

Branches can damage membranes during storms. Maintain a 3-meter clearance from roof edges.

3. Address Damage Immediately

Small punctures become big leaks. Repair any damage as soon as it's discovered.

4. Professional Inspection

Schedule a professional inspection every 2-3 years. Early detection saves money.

5. Document Everything

Keep records of all inspections, repairs, and maintenance. This documentation is valuable for warranty claims and property sales.
