Do you need to apply a waterproofing agent like Tuff n Dri to a below grade retaining wall if 5000 psi concrete is used?

the 5,000 psi is the amount of pressure the concrete can withstand before it will crush. it has nothing to do with water proofing. to find out if you need water proofing you need to know how poores the concrete is and how quickly the ground out side will drain water. it only takes about 6 psi for water to penatrate most concrete walls, it is more a matter how long the water is alowed to stay against the wall, there for how far through the concrete it can penatrate if you have a good working drain you will most likely never need water proofing. but if you dont own a backhoe it is far cheaper to put it on the outside before the hole is filled.

What does the s mean in concrete?
The 's' stands for 'slump'. How wet the concrete is. S1 is prity dry (for laying kerb stones). S2 is wet (for foundations). S3 is very wet (pump mixes). Regards Colin, a Tarmac concrete batcher. 2nd Answer: It should be noted that the concrete should be as dry as practical to enable it to attain the highest potential strength. Concrete should never be so wet that it flows into the forms like tomato soup. In foundations in particular, you want the best strength you can get, as the entire structure will apply force to them. It should take some handwork with shovels to "ker-chunk" the concrete into the nooks and crannies of the forms. For vertical forms, using a 'stinger' or vibratory device is preferred to settle the concrete into all the nooks and crannies. A 4" slump is about as wet as you want the concrete mix to be. If you pick up a handful (with gloves) of fresh concrete and mold it into a fat cigar shape, it should hold that shape when you open your fingers. When the concrete mix comes down the chute of the delivery truck, it should stand up on the ground in a little hill, but with some spreading out, too. For all but the dry structural concretes, you can increase the fresh concrete's slump (wetter) by adding 1 gallon of water for each cubic yard of concrete for each additional inch of slump desired.

Doubly reinforced concrete vs singly reinforced?
Doubly reinforced concrete and singly reinforced concrete are two types of reinforced concrete structures that differ in the way reinforcement is provided to resist tensile forces. Singly Reinforced Concrete: Singly reinforced concrete refers to a structural element (such as a beam or a slab) where reinforcement is provided only on one side to resist tensile forces. Typically, steel reinforcement in the form of bars or meshes is embedded in the concrete in the tension zone, where the concrete is subjected to tensile stresses. The reinforcement helps to carry the tensile forces, while the concrete primarily resists compressive forces. Singly reinforced concrete is commonly used in many structural applications. Doubly Reinforced Concrete: Doubly reinforced concrete refers to a structural element where reinforcement is provided on both sides to resist tensile forces in different zones. In addition to the primary reinforcement on the tension side, secondary reinforcement is also provided on the compression side to increase the structural strength and control the development of cracks. The secondary reinforcement helps balance the tensile and compressive forces, improving the overall performance and load-carrying capacity of the element. Doubly reinforced concrete is often used in situations where higher strength and resistance to cracking are required, such as in deep beams or heavily loaded structural members. The decision to use singly or doubly reinforced concrete depends on factors such as the structural requirements, loads, span lengths, and design considerations. Doubly reinforced concrete is typically employed in situations where the loads are higher or where there is a need to control deflection or cracking to a greater extent. It provides enhanced strength and ductility to the structural element. However, it also requires careful design and detailing to ensure proper placement and spacing of the reinforcement on both sides. It's important to note that the design and implementation of reinforced concrete structures should always be carried out by qualified structural engineers who consider the specific project requirements, local building codes, and safety factors.
Stop metal rusting?
Provide a coating to the surface of the metal either a permenant or temporary. For a permenant coating, apply a paint or lacquer formula For a temporary coating, apply either oil, wax or pollish, which you will have to replenish often
Can you apply wet concrete to dry concrete?
Yes, you can. You should clean the dry concrete with water and a brush first, and you should use a bonding agent (available pretty much anywhere you buy concrete) for optimal adhesion. You may also wish to add reinforcement such as rebar.

The Process of Foundation Waterproofing?
Foundation waterproofing is a process used to prevent water from absorbing into a structure's foundation. The majority of foundations are made with concrete, which means they can eventually crack and erode if enough water seeps into them. Several methods of foundation waterproofing are used, each with different benefits. When appropriately done, foundation waterproofing will last for decades.Liquid Membrane WaterproofingWith this type of foundation waterproofing, liquid membranes are brushed or sprayed on the concrete's surface before dirt is back-filled around the foundation. The liquid membrane is applied thickly and when it dries, the substance has a rubber-like consistency. Liquid waterproofing is not only easy to apply but also inexpensive to complete. While the process does not take much time, the waterproof covering tends to vary in its thickness. The installer's skill level will determine how uniformed the waterproof covering will be.Sheet Membrane WaterproofingSheet membranes are another way to waterproof an exposed concrete foundation. This waterproofing material is formed in large sheets made of asphalt and a substance similar to rubber. These materials are attached to plastic-like membranes. The backside of each membrane sheet is applied to a sticky adhesive that is covered by a paper backing.During the application process, the paper on each sheet membrane is removed. Then, the sheets are pressed firmly against the foundation. Careful application is necessary because the adhesive will immediately stick to the surface. It is necessary for two people to apply and smooth out a single sheet; one person works at the top while the other person works at the bottom.Once the membrane sheets are applied in a side-by-side configuration, a certain type of tape is placed over the seams. After the seams have been taped, the foundation can be back-filled with dirt. The main advantage of sheet membrane foundation waterproofing is that the material has an equal thickness and does not take a long time to dry. The negative aspects of sheet membranes are their high cost. And if it is installed incorrectly, the sheet will be destroyed when removed.
