Are YOU seeking a more sustainable solution for YOUR polystyrene underslab sheet requirements? Our concern for cost to YOU, cost to our community, and the cost of consuming 100% imported material versus clever local sustainable production, has led to the development of our unique 100% recycled Ecoslab sheets for underslab applications.

Ecoslab Underslab Sheets with white rock™ technology

Poly Palace's commitment to innovation and sustainability, as we continue to expand our 100% recycled white rock™ product range, has resulted in our superior bearing strength Ecoslab Underslab sheet.

High quality polystyrene packaging, designed specifically for superior compaction resistance, following its short life protecting the global transportation of consumer goods is re-purposed to provide the same superior compaction resistance under YOUR concrete slab.

  1. Ecoslab Underslab Sheets provide the bearing strength and insulation performance suitable for underslab applications at the lowest cost.
  2. Ecoslab Underslab 1.2m x 2.4m sheets are available in thicknesses from 50mm to 500mm.
  3. Ecoslab Underslab Sheets have an R value exceeding R2 per 100mm of thickness.
  4. Ecoslab Underslab Sheets have the maximum durability rating under the New Zealand Building Code (50 year +).
  5. Ecoslab Underslab Sheets do not contain brominated flame retardant. International agreements (The Stockholm Convention) require brominated flame retardants to be to be phased out of polystyrene manufacturing by 2019.
  6. Ecoslab Underslab Sheets are re-manufactured from 100% recycled and graded post consumer polystyrene.
  7. Ecoslab Underslab Sheets are locally manufactured for the local market from local waste saving significant space and cost in local landfills.
  8. The factory direct price of Ecoslab Underslab Sheet is up to 50% less than the DIY store retail price for the alternative of virgin manufactured 'S' grade polystyrene sheet.

Palace Pods add sustainability and strength to increasingly popular ribbed raft waffle slabs. Following the Christchurch Earthquakes ribbed raft waffle slabs are now the preferred and government endorsed solution for domestic and light commercial concrete slab construction.

Palace Pods with white rock™ technology

Palace Pods ribbed raft waffle slabs comprise a grid of polystyrene 'Palace Pods' separated by spacers and reinforcing rods. A single pour of concrete forms both the reinforced concrete ribs in the grid between the 'pods' and the raft slab providing unparalleled strength.

Put your building project on the best foundation with engineered strength, quality, simplicity & economy by specifying a Palace Pod ribbed raft waffle slab.

  1. FAST : By eliminating foundation trenches and simplifying site preparation, Palace Pods ribbed raft slabs are simple and quick to construct. Meet YOUR slab construction targets in any weather with Palace Pods. 
  2. COST EFFECTIVE: Palace Pods ribbed raft waffle slabs save time, energy and resources guaranteeing a higher performing slab at the lowest cost..
  3. STRONG: Engineered inherently strong Palace Pods ribbed raft waffle slabs require only half the soil bearing strength required for a conventional slab, without cracking or slumping.
  4. APPROVED & ENDORSED: Following investigation of building performance in the 2010 Christchurch Earthquakes, ribbed raft waffle slabs are now officially recommended as a preferred alternative to traditional slab construction.
