Proudly introducing Polyguard vaults made in the United States for caskets. We have 2 styles of casket burial vaults; the Hercules dome and base, and the Atlas tub and lid. These poly vaults are the perfect alternative to concrete, and are true sealed units keeping moisture in and out. These poly vaults are light-weight and do not require any large boom trucks to install at the grave site. Below is our selection of quality and affordable Polyguard burial vaults for caskets.
