Park and Restroom Structures

Vault Design

Vault Technology

  1. OSHA Requirements
    • All Park and Restroom Structures' vaults meet OSHA requirements for installation in a hole that is less than 4' deep. All of our vaults are 3'6" deep, giving you the customer, additional space beneath the vault itself to add compacted gravel or squeegee materials for the vault to set securely on and still meet all OSHA requirements for a safe and effective installation. It is illegal to ask or allow someone to climb into a hole that is 4' deep or deeper without structural steel supports on two full sides of the new hole or without digging from the bottom of the hole up, at a minimum of 45 degrees or better, to insure that the sides can't fall in on workers that are grading or screeding the base of the hole in anticipation of the precast concrete vault installation into that same hole.


  2. Soil Displacement
    • Our vaults displace just under 80 cubic feet less soils, rocks and other materials per vault than those of other producers, when preparing a new hole for installation of a precast concrete vault. Less displaced soil and rock means less to backfill and compact with a newly installed vault, less< high water table to contend with and less rock to dig through or blast out in those tough rocky spots where precast concrete restroom structures typically go.


  3. Vault Liner
    • Our vault interiors are lined with a black spray on liner material in order to meet the aspects of a double containment vault as spelled out in the Sweet Smelling Technology book. That spray on liner material is not negatively affected by UV rays and it stays pliable for over forty plus years of use, unlike ASB vault liners that continue to become brittle and nonflexible with age and also with exposure to natural sunlight before they are installed out in the field and under a structure.

    • Our black spray on vault liner material will not separate from the concrete vault over time, can't be damaged by a pumper's standard pumping equipment and will keep waste safely within the vault and hydrostatic water out of the vault in the event of most earthquakes, soil movement and tree root growth.


  4. Capacity
    • Our precast concrete waste containment vaults have a capacity of 1,200 gallons when completely empty. Having a larger vault capacity means the restroom facilities will need to be pumped out less often than those smaller waste containment vaults found by other precast concrete vault
      producers. This benefit will save customers a great deal of money over the many years of use of the facility in the field.


  5. Sanitation
    • Our vaults have a steeper slope than competitor's vaults which helps solid waste slide to the bottom of the vault. By having the solids towards the bottom it will help keep the solids covered by the liquids which will prevent flies from breeding.


  6. Easy Installation
    • Our vaults are picked from lifting embeds on the top surface of the vaults making installation of them easier and safer than side vault lifting devises typically found by other precast concrete vault producers.


  7. Best Warranty
    • Our vaults come with a 10 year warranty against leaks when installed properly and with one of our facilities correctly sealed and installed on top of the vault or vaults in the field.
