What are Rika Blocks™?

Rika Blocks™ are a pre-cast EPS concrete foundation block.

Engineered to make the art of building quicker, better and easier.

What makes using  Rika Blocks™ better?

  • Designed to support 38mm, 50mm (All heights) and 95 x 95 posts for elevated structures or sloping ground.
  • Use on any surface including sand, paving, gravel etc.
  • Light in weight but strong in design. (weight 15kg – holding capacity 500kg per unit)
  • Take the effort of digging holes and planting posts out of the equation.
  • Rika Blocks™ manufacture using recycled polystyrene. (Polystyrene is a nasty by-product of convenience).
  • Save hours if not days using the Rika Blocks™. Concrete takes 7 days for first stage curing. Every Rika Block sold has cured over 30 days.
  • Contractors, why not increase your productivity and reduce your labour expenses, carry fewer tools to the site, and stop working with messy concrete.

What can Rika Blocks™ Be used for?

To support structures like Decking – timber or composite, Rain Tank Platforms, Boardwalks, Wendy Houses, Modular / POD Homes, and more.

Rika Blocks™ – they just make sense.


Rika Block specs

The  Rika Blocks™ are moulded using a concrete mix called EPScrete: EPS concrete or (lightweight concrete) is a form of concrete known for its light weight made from cement and EPS (Expanded Polystyrene). It is a popular material for use in environmentally “green” homes.

It is created by using small lightweight Styrofoam or EPS balls as an aggregate instead of the crushed stone that is used in regular concrete.

Only recycled Styrofoam is used.

No more will constructing a deck, supporting a structure or setting up posts be a massive event.

Added benefits with using  Rika Blocks™ are:

If you are renting a property and construct a deck, you can easily disassemble the structure and reassemble on a new site. Can be used to elevate a Wendy House, Dog Kennel, Rain Tank or Kids Playhouse……etc.

Just   Block™ it!
