Polyethylene Under Concrete Slabs - GreenBuildingAdvisor

What goes under the concrete in a slab-on-grade home? In the old days not much — just dirt. Eventually contractors discovered that it made sense to include a 4-inch-thick layer of crushed stone under the concrete. The crushed stone provides a capillary break that reduces the amount of moisture flowing upward from the damp soil to the permeable concrete. Since the crushed stone layer .【Get Price】

Choosing Between EPS and XPS Rigid Insulation Concrete .

When it comes to concrete and insulation contractors tend to be most familiar with extruded polystyrene XPS . Yet expanded polystyrene EPS performs as well or better than XPS and at a substantially lower cost.【Get Price】

How to Make Lightweight Concrete Using Styrofoam Hunker

Lightweight concrete also known as EPScrete expanded polystyrene concrete is a material widely used in the building of environmentally "green" homes. The substance is often made using small Styrofoam balls as a lightweight aggregate instead of the crushed stone that is used in regular concrete.【Get Price】

EPS Foam Insulating Board: Expanded or Extruded Polystyrene .

Our photo above left shows polystyrene foam insulating board below a concrete slab being poured in Two Harbors MN. Answer: Widely reported research by Dow Chemical Co. shows that their extruded polystyrene foam insulation on average outperforms expanded polystyrene EPS in below-grade insulation appli ions.【Get Price】

SilveRboard: Reflective and Under Slab EPS Insulation Amvic

SilveRboard is a rigid insulation board made from Expanded Polystyrene EPS covered with a layer of polypropylene reflective lamination on both sides. This highly effective combination of materials offers high compressive strength and great thermal performance when used in below grade and under slab appli ions.【Get Price】

EPS Insulation - Universal Construction Foam - Expanded .

An 8" hollow concrete block the type used for most concrete block walls only has an R-Value of 1.11. EPS insulation blocks that are 5" thick have an R-value of R-20.5 or greater. Simply by placing the EPS blocks inside the concrete block voids while the foundation wall is being built that R-1.11 insulation value for the block wall is turned .【Get Price】

Right-sizing Under-slab Insulation – Insulfoam

Rigid foam insulations such as expanded polystyrene EPS have been used successfully under concrete slabs for more than 40 years. Such insulation helps reduce heat loss to the ground in residences cold storage units warehouses and other commercial institutional and industrial structures.【Get Price】

The Barrier Insulation - High Performance Under Concrete .

The Barrier product family is a high-performance EPS foam underslab insulator and vapor retarder designed to insulate and retard moisture migration through concrete. The core of the Barrier roll products is made of flexible recycled expanded polystyrene that provides the excellent insulation characteristics.【Get Price】

Below Grade and Under-Slab Building Insulation Modern .

Two of the rigid foam insulations most commonly used below grade and under slabs are expanded polystyrene EPS and extruded polystyrene XPS . Although both are closed cell insulations they perform very differently over the long term.【Get Price】

Compressible shrinkable Insulation EPS

Compressible EPS is a low density expanded polystyrene compressible-fill material which can be used to reduce the pressure exerted on reinforced concrete ground beams or on the vertical face of concrete foundations caused by the expansions of clay soils--clay heave--during the life of the structure.【Get Price】

Placing a Concrete Foundation on Rigid Foam Insulation .

However after extensive research it became clear there is a long history of using certain types of very high density expanded polystyrene EPS foam insulation underneath major structural works of all kinds including roadways bridges and runways. Our concerns receded based on the evidence and we were swayed — yet still reserved and cautious.【Get Price】

Frost-Protected Shallow Foundations: Saving Energy and .

An FPSF foundation consists of a standard concrete slab with thicker edges sheathed in rigid-foam expanded polystyrene EPS or extruded polystyrene XPS insulation Figure 1 . Where approved other rigid-foam products such as polyisocyanurate may be used but are not yet prescribed in U.S. model codes and standards for FPSF appli ions.【Get Price】

The Dirt on Below-Grade Insulation – Insulfoam

Contractors are increasingly called upon to install rigid foam insulation under concrete slabs and on building foundations. Up to one-quarter of a building’s energy loss is due to lack of insulation in below-grade areas including the foundation and under slabs.【Get Price】

Placing a Concrete Foundation on Rigid Foam Insulation .

Termites and Foam Here& 39;s another data point for rigid foam under footings: In our one-family pre-certified PassivHaus in northern NJ we used 4-inches of Type IX EPS under the poured-concrete footings. We used four inches of Type I EPS to encase the sides of the footings and on the poured-concrete exterior walls of the foundation.【Get Price】

GEOFOAM - Expanded Polystyrene Soil Substitute

Expanded polystyrene EPS foam has been used as Geofoam in geotechnical appli ions for more than 30 years. The extraordinary properties of EPS make it a great choice for use as a slope stabilizer retaining wall backfill road embankments or pavement insulation to name a few.【Get Price】

Polystyrene or Styrofoam Beads Universal Foam Products .

Puffed polystyrene beads weigh just under 1 lb per cubic foot. There are appli ions when the strength of concrete is needed but the weight of the concrete is a problem. One solution is to mix puffed polystyrene beads into the concrete mix. As the puffed beads displace the other components of the concrete mix the material becomes lighter.【Get Price】
