Structural Slab Forming Solutions
Plain non-structurally reinforced Cupolex® slabs can be economically and successfully used for a wide variety of load and site conditions. However soils with very low bearing capacity, high compressibility, or that are highly expansive may require remedial treatment or special slab designs.
Over the past 3 decades, the idea of placing concrete over CUPOLEX® permanent void forms has become an increasingly popular foundation method, not only for site conditions involving challenging soils, but replacing conventional slabs that are not very well known to provide healthy interior environments. Building designers and developers strive to assure better results and protect themselves and their product from criticism and failure. They are constantly facing challenges when designing and installing slabs on ground including the following:
- Structural failure
- Slab curling and shrinkage,
- Reducing the environmental impact of building,
- Lowering building costs and the carbon footprint,
- Reduce the cycle time of building,
- Post construction settlement of soil below structures
- Reduce aggregate use and the use of importing and engineering fill
- Seeking alternative design to not using light weight fill or EPS fill to reduce dead loads on structures
- Moisture and mold prevention,
- Expansive and challenging soil conditions,
- Accumulating points for LEED certification.
Both slab on grade and ribbed structural slabs on grade can be created using Cupolex. There are significant cost savings to the builder and owner by using the CUPOLEX® flooring formwork in the design of concrete slabs for residential, industrial, commercial and institutional applications in sites with structural site challenges and contaminated and low bearing soil conditions.
Traditional old fashioned void forming systems for in-situ ground slabs and beams, subslab gravel drainage layers, and light weight or imported engineered fill are increasingly being replaced by Cupolex, a quicker and less labor intensive alternative. A trend that is encouraged by the emphasis on fast track build programs, lowering construction costs and a shortage of skilled tradesmen. Reacting to this trend, Cupolex has developed a complete design and supply service for an extensive range of slab formwork systems.
Cupolex – Structural Ribbed Concrete Slabs
Plain non-structurally reinforced slabs on grade can be economically and successfully used for a wide variety of load and site conditions. However soils with very low bearing capacity, high compressibility, or that are highly expansive may require remedial treatment. CUPOLEX can provide a Special slab design such as a structural reinforced slab, a slab that includes stiffening beams or a slab not directly supported by the soil such as on a beam/pile or stem wall foundation.
Cupolex – For Structural Fill Replacement
The quality of excavated material typically plays a major part in the cost of site development. Often, sites are designed to minimized soil import or export, but without regard to the quality of the stripped and excavated material. The material generated from the cut operation may not be suitable for the fill requirements. The fill under structural areas generally require import, and the site may yield more poor quality material than will fit in the non-structural areas. An expensive haul-off and/or an expansive import would generally be the result.
Cupolex – Slab Solutions For Reactive & Expansive Soils
The problem of “expansive soils” is well known to engineers and builders. It affects construction sites in mane site around the world, and particularly those in the desert, Rocky Mountain and the mid-continent Regions in NA. To avoid the build-up of these potentially damaging forces, slabs and foundations must be designed to accommodate any ground movement that is anticipated.
