Pad Specifications:

The preparation of the pad for your Rhino Tank is the responsibility of the customer. Our preferred base material is fine crusher dust; however, if crusher dust is not available in your area please insist on using screened course river sand. It must be free of sticks, stones and clay lumps (6mm diameter or less).

  • Level Pad (+/‐ 10mm)
  • Minimum thickness of pad is 150mm or 6 Inches.
  • Dimensions are outlined in the pad size/specification sheet below.
  • Ensure adequate compaction of the sub soil to avoid subsidence for deep pads.
  • The customer is required to place an exclusion zone of minimum 10mm Blue Metal/Stone (no clay or concrete) around the base of the tank after installation to prevent erosion and deter rodents from digging around the base.

If Site Access or the Pad Quality is not adequate, it may be necessary for our installation team to leave the tank and re‐schedule the installation (possibly weeks) until the problem is corrected. Unfortunately, this will incur additional charges over and above the specified cost (to cover wages and travel).

Site Access:

  • Please ensure adequate access to the site for a small truck or 4WD and trailer, bearing in mind soil and weather conditions.
  • Access is to be available to within 10 metres of site.  
  • If unable to meet these requirements please contact Tanclean- Rhino Water Tanks to make alternative arrangements.

On The Day:

Attendance: You are most welcome to attend on the day but it is not essential. It is difficult to finalise a particular installation date in advance due to the weather, freight and labour. 

Water: The Customer is required to arrange water supply of a minimum of 35 – 40 % volume of tank capacity being built in terms of literes of water upon competation to stabilize the liner. This amount represents an average of a single tanker load of water for the smallest size of ourtank: RT-25. Please note that tank installation may have to be postponed and additional charges would be levied in case water is not made available immediately after installation.
Note: Rhino Water Tanks & Liners are suitable for the storage of water within a PH range of 2-12 and a Temperature range of -20 Deg Cent. to +40 Deg. Cent.

PAD PREPARATION

With a spirit level on top of a screed, level out the sand or crusher dust using a temporary pole in the centre of the pad as a pivot point.

PAD PREPARATION

Level existing site therefore pad preparation is resonably straight forward.

PAD PREPARATION

Slightly sloping site therefore pad needs to compensate slope to ensure it is in level.

PAD PREPARATION

Site has been cut in to create level base therefore we recommend a drain to be dug into the slope above the pad to allow water runoff to be diverted around the tank when it rains.

PAD PREPARATION

A typical pad of 150mm crusher dust with thin layer of washed river sand on top. This pad was for an RT-100 (104,000 lt) Rhino Tank.
