Frequently Asked Questions
How often should a hydrovac tank liner be replaced?
Quality liners last 3-7 years depending on usage volume and material type. Annual inspections help catch wear before it leads to tank wall damage.
What is the difference between a spray-on coating and a drop-in liner?
Spray-on coatings bond directly to the tank wall and are thinner. Drop-in liners are thicker, replaceable panels. Spray-ons are lighter; drop-ins offer easier replacement.
