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.

How can I ensure effective waterproofing of a concrete slab?
To ensure effective waterproofing of a concrete slab, you can apply a waterproofing membrane or sealant on the surface of the slab. This will help prevent water from seeping into the concrete and causing damage. Additionally, proper drainage and slope design can also help in keeping the slab waterproof. Regular maintenance and inspection of the waterproofing system is important to ensure its effectiveness over time.
How can I effectively waterproof concrete structures?
To effectively waterproof concrete structures, you can use specialized waterproofing materials such as sealants, membranes, or coatings. These materials create a barrier that prevents water from penetrating the concrete. It is important to properly prepare the surface, apply the waterproofing material according to manufacturer instructions, and regularly maintain the waterproofing system to ensure long-lasting protection.
Why apply a coat of bitumen on concreting?
Applying a coat of bitumen on concrete serves several purposes. It acts as a waterproofing agent, preventing water infiltration and protecting the concrete from moisture damage. Additionally, bitumen improves adhesion for subsequent layers, such as asphalt, and enhances the overall durability and longevity of the concrete surface. This treatment is especially beneficial in areas exposed to harsh environmental conditions.
How can I effectively waterproof a concrete floor to prevent water damage and ensure its long-term durability?
