Underpinning is an action that is used to strengthen the foundation of a property and is subsidence solution. You can sell a property that has been underpinned as long as it has been completed to a good standard and there are no ongoing structural or subsidence issues. You should not pour concrete over the grass directly. For your concrete to harden flat and smooth, it is best to clear all vegetation and pour the concrete on top of smooth and debris-free soil. Leaving grass under your concrete slab can cause some unnecessary issues for you in the future. Epic Contributor. For soil cement the CRUSHED gravel should have poper mix of fines to larger pieces to make it as dense as possible. Add the proper amount of cement and water and mix well by some mechanical means, smooth to grade and pack it. The mix is not a slurry and is very hard to tell from damp gravel. Sand needs to remain damp as well as other material before placement of the concrete.

Crumbling concrete can be repaired before crazing occurs. Crumbling concrete is not just unsightly, it may also be a sign of serious damage beneath the structure. Address the problem as soon as possible to prevent it from spreading or causing other damage, such as crazing, in which a network of random cracks occurs. The process can be lengthy and expensive, costing anywhere between £5,000 and £50,000 depending on the size of the property and the extent of the damage. Though figures differ, it is estimated that as few as only 10% of properties suffering from subsidence will require underpinning. If done properly, new concrete can often be poured right over an existing slab. ... For this to be feasible, the contractor needs to pour at least 2 inches thick, use smaller aggregate, and incorporate reinforcement such as welded wire mesh or fiber mixed into the concrete.

Sand needs to remain damp as well as other material before placement of the concrete. If you want to build a road, use gravel, but this does not mean you will not have issues. You can put new concrete over old concrete. However, unresolved issues with your old concrete, such as cracks or frost heaves, will carry over to your new concrete if not taken care of. In addition, you must pour it at least 2 inches thick. Yes, concrete can last hundreds of years, but cement is much less durable. To use an analogy, cement is to concrete as milk is to ice cream. Sure, ice cream has milk in it, but it isn't milk. It's actually much better. Concrete is inherently water-resistant, so it is an ideal construction material for structures such as basements and bridges. ... With a higher water/cement ratio, the concrete will become more porous.
