What is the solution of a failed concrete slab?
Find the reason for the failure and correct it. May have been soft, damp ground under it, maybe it should have had wire or steel re-inforcement. maybe it hardened too quickly - -there could be many reasons, pouring good slabs is a definite technique, not for amateurs.
What is the purpose of polythene plastic barrier under concrete foundations?
hi, im not absolutely sure but i think my geography teacher said once that its to help absorb sock in case of an earthquake
How do you move toilet plumbing that is under concrete?

Why would you need to pump sand under your house?
generally they pump sand or gravel under house for the footers and the foundation. the sand or gravel helps to make the concrete they are going to pour shift or move less than what it would if it where just on the ground/ dirt, it also creates a barrier from the moisture in dirt. usually depending on state building codes the thickness of the sand or concrete should be between 4" to 12". In cold weather they like to use sand because it does freeze as hard as soil.
Why is concrete often reinforced with steel?
concrete is excellent under a compressive force and terrible under a tensile (stretching)force. Rebar is added when concrete is subjected to tensile forces.
Should polystyrene be installed under concrete?
yes, as a moisture barrier
Where does the sweat on the concrete slab under vinyl plank flooring come from it has grown mold under the plank and am concerned for obvious health reasons?
Moisture can migrate through a slab foundation. Older slabs did not have a vapor barrier but I have seen it on newer slabs as well. Vinyl flooring will develop mineral deposits or lumps and discoloration. Wood flooring will warp. Carpet will sometimes work without problem or may mildew. Surprisingly, tile works well as it will allow moisture to migrate through the grout joints.
How much gravel should be placed under concrete for proper installation?
A minimum of 4 inches of gravel should be placed under concrete for proper installation.
What is a vapor barrier under a wood floor?
Vapor is another word for moisture. A vapor barrier is a sheet of plastic covering the entire surface under the floor to prevent moisture from causing the floor to warp or absorb stains. You would typically use a vapor barrier in basements with concrete floors.

What type of gravel should be used under concrete for proper support and stability?
Crushed stone or gravel with angular edges is recommended for use under concrete to provide proper support and stability.

Stone slabs are stronger under compression or tension?
Stone slabs are stronger under compression than tension. This is because most stone materials are able to withstand higher forces when being compressed rather than being pulled apart. Stress is distributed more evenly and effectively in compression, making stone slabs less likely to fail compared to tension.
For a house on a concrete slab what kind of moisture barrier do you need for putting down hardwood floors in the kitchen if any?
Many people assume that a moisture barrier is needed and that it would actually work... OOPS, not so. Concrete actually pumps water up through the concrete through the same bit of physics magic that makes you capillaries work, not surprisingly its called capillary action. No moisture barrier is going to stop the pumping action and in fact may cause more problems, because once the moisture comes up, under the barrier it cant evaporate & will pool & feed bacteria & mold. The right answer is to use an engineered hardwood that will stay down without cupping & swelling and allow the concrete to breath & evaporate
Can you plant a seed in concrete?
