Answers Before You Book
Frequently Asked Questions
Is the waterproofing chemical safe for drinking water?
Yes! We strictly use certified food-grade, potable-water approved crystalline and 100% solid epoxy coatings that release zero toxic chemicals or smells.
How long does a water tank waterproofing treatment take?
Cleaning, crack repair, coving, and applying 2 coats of food-grade waterproofing typically takes 2 days, plus 24 to 48 hours curing before refilling.
Can you fix a leaking underground water sump without digging around it?
Yes, we waterproof from the interior (negative-side) using high-strength crystalline technology that penetrates deep into the concrete to seal incoming and outgoing leaks.
How often should a concrete water tank be waterproofed?
Quality crystalline systems last 10+ years. We recommend periodic cleaning and inspection every 1 to 2 years.
