Using a blower truck is the perfect solution for applying mulch on at-grade septic systems. Our application process enables minimal soil disturbance and access is never an issue as our hose lengths can reach up to 600 feet. The mulch covers and insulates while controlling odors and seepage. Mulch is an approved cover material for at-grade systems.
Top Spray works in conjunction with septic builders and installers as well as residential owners for top-ups.
