What Problems Does Moisture Create? Without a vapor barrier, the relative humidity in the slab just below the surface can often be 100%. Since the air is seldom that humid, moisture is going to move from the slab into the air and as the surface dries a bit it will draw moisture up from the bottom.ithout a vapor barrier, the relative humidity in the slab just below the surface can often be 100%.

How to Install a Basement Vapor Barrier A basement vapor or moisture barrier is installed during the new construction of a home or the remodeling of a basement. Polyurethane sheeting is a typical vapor barrier that contractors use to prevent moisture from penetrating the walls of a basement.The material is stapled to the frame of a basement wall before it is finished with plaster or drywall. vapor barrier is useful for keeping moisture from making its way into a basement, keeping mold and water damage at bay.

Thread: How thick to make concrete floor?? So many concrete installers today are not concerned with how the slab stays together long term, and so they add a lot of water at the site in order to make the concrete easier to work, and they will puncture the vapor barrier in order to decrease the time delay from pouring to final finishing.

What is a typical size of a fully loaded pallet in the U.S.? But since you asked for cubic feet...a standard US pallet is 40 inches by 48 inches. A standard semi-trailer height is around 110 inches, so you could possibly pile the stuff that tall as long as you did not overload the weight the pallet could support. Provided that the items did not really overlap or under-lap the pallet, you are looking at 40 inches plus 48 inches plus ---> now the height.

Visual Inspection of Concrete Floating and/or troweling operations following the. condensation of moisture from warm humid air on. cold concrete. In cold weather concrete sets slowly, in particular, cold concrete in basement floors. If. the humidity is relatively high, water will condense. on the freshly placed concrete, which, if troweled. into the surface, will cause dusting. d. Inadequate ventilation in enclosed spaces.

Myths and misconceptions about concrete and water In fact for houses, foundation walls and often footings are covered with a moisture barrier to help keep the concrete dry -- actually to help stop the migration of water from the soil through the concrete and into the house.es as Mike says you can cover concrete with plastic and it will setup very well, in fact that is often done to help it set-up in dry weather. No, water does not become part of the concrete and it will eventually reach equilibrium with the environment around it, either getting wet or drying out.

Polyethylene Under Concrete Slabs ACI standard 302.1 R-96, Guide for Concrete Floor and Slab Construction, included this recommendation in Section 4.1.5: “If a vapor barrier or retarder is required due to local conditions, these products should be placed under a minimum of 4 inches (100 mm) of trimable, compactable, granular fill (not sand).”.n the April 2001 issue of Concrete International magazine, the ACI advised that for slabs with vapor-sensitive coatings (i.e., virtually any kind of flooring), the vapor retarder should be installed directly under the slab, with no intervening layer of granular fill.

- To prevent efflorescence, moisture must be blocked and the best way to do this is with a vapor barrier. The other option is to apply a sealer or coating to the concrete once it is dry and clean. You can clean efflorescence, and depending on the stage of its formation will require different methods.

superplasticizer You are here: Home / superplasticizer. Concrete admixtures is a liquid additive for concrete. It is sulfonated melamine formaldehyde (SMF) popularly known as melamine based super plasticizers. When water and cement are mixed, cement particles tend to agglomerate inhibiting dispersion in water.

What Problems Does Moisture Create? These principles mean that if the relative humidity in the concrete slab is different than the relative humidity of the air above the slab, then moisture is going to try to move in or out of the slab. Without a vapor barrier, the relative humidity in the slab just below the surface can often be 100%. Since the air is seldom that humid, moisture is going to move from the slab into the air and as the surface dries a bit it will draw moisture up from the bottom.

- Even after taking care of any moisture issues, your basement can become a damp place. You'll need to add a vapor barrier to both the walls and floors prior to framing and finishing off these surfaces. It's a good idea to lay down a vapor barrier for a day or two, then check underneath to see if and how much moisture may be coming through before continuing. Photo By: yanukit.

What Is a Concrete Foundation for a Mobile Home? A mobile home may be temporarily parked on a concrete foundation or permanently affixed. Temporarily parked mobile homes are usually considered personal property. Personal property generally depreciates over time. When a mobile home owner affixes the home to a concrete foundation, it may become real property.

5 Myths about Concrete Moisture 5 Myths about Concrete Moisture. 1  MYTH #1: If the surface is dry, the slab is dry. 2  MYTH #2: All floor products have similar moisture tolerances. 3  MYTH #3: The concrete is “old” so it has to be dry.  MYTH #4: The slab is not on grade so I don’t need to do moisture 1  testing. MYTH #5: Surface testing gives a final moisture level.

Concrete floor slabs on ground 1 The concrete slab should be at least four inches thick. 2  A monolithic slab is usually preferred in termite areas. 3  After leveling and screeding, the surface should be floated with wood or metal floats while concrete is still plastic. Insulation may extend down on the inside of the wall vertically or under the slab edge horizontally. 2  The slab should be reinforced with six by six inch No. 10 wire mesh or other effective reinforcing. 3  The concrete slab should be at least four inches thick.

How To Build a Successful Sunroom Understand that a sunroom could increase the need for mechanical ventilation in the rest of your house. Plants can add a lot of moisture to the air. If your sunroom is to be built on a concrete slab, insist that it be insulated underneath with at least 2 inches of extruded polystyrene foam.

- this source of wetting is ameliorated somewhat by the stepped down block shelf in the slab which results in less resistance to passage of liquid water to the outside through the relatively more porous concrete block and stucco than to the interior through the concrete of the slab

- Avoid placing a slab directly on polyethylene film or other vapor barriers. Use a 100-mm (4-in.) layer of compactible, drainable fill (not sand). A “crusher run” material, usually graded from 38 mm to 50 mm (1-1/2 in. to 2 in.) down to rock dust, is suitable.Following compaction, the surface can be choked off with a fine-grade material to separate the vaporbarrier from the concrete.5.void placing a slab directly on polyethylene film or other vapor barriers.

- Some specifiers re-quire a sand layer or a crushed baseover the vapor barrier. Others insistthat the vapor barrier be placed direct-ly under the slab. Specifiers must care-fully consider the effect of the locationof the vapor barrier on the perfor-mance of the concrete slab.f the vapor barrier is usedonly to reduce subgrade friction,punching holes in the vapor barriermay be permitted (Ref. 3). Vapor barrier effect on subgrade friction Some engineers believe that placingthe vapor barrier in contact with theconcrete slab reduces subgrade fric-tion.

- Use Plants to Divert Water. Plants and shrubs will not waterproof a foundation, but they are a cost effective way to keep your basement dry and to avoid straining the waterproof treatment which you've placed on the concrete. Plant flowers, bushes, and shrubs several feet away from the foundation wall to reduce standing water.

- It will be slab on grade with radiant heat in floor. I'm going to run the domestic water supply (PEX tube) to each bathroom, sinks, toilets etc. in the concrete but inside of 1-1/4 PVC pipe in the concrete.) Make sure that the PVC pipe does not detract from the thickness of your slab to the extent that it would weaken the concrete and lead to a potential crack path. Cross wire mesh and re-bar in the concrete will help a lot but consider some additional thickness in areas where the pipe is embedded.
