How do you waterproof a slab on grade foundation?
Use polyethylene sheet membrane. Prior to concrete placing, cover the entire area with a layer of PE sheet membrane extending the perimeter of slab and up against wall for the depth of concrete.
Are concrete blocks cheaper then a concrete slab?
That's sort of a strange question. A concrete slab is a horizontal surface -- it's meant to be a surface you stand on or build things on. Concrete blocks are usually used for vertical surfaces -- walls. I believe that poured concrete walls are more expensive than concrete block walls. You wouldn't use concrete blocks as a substitute for a concrete slab.
Can a slab on grade be a floating slab?
In laymen's terms, yes. Many people use the terms Slab-on-grade & Floating Slab interchangeably. However, architects, engineers, and construction workers may have a more refined interpretation. Most commonly, a Slab-on-grade construction refers to a foundation in which the a concrete slab (also most commonly thickened at the perimeter) rest directly on grade (aka ground). Where as a Floating Slab foundation refers to a concrete slab resting directly on the grade independently placed within a stem wall (aka foundation wall), which extends down to the depth of the local frost line, running around the entire perimeter. The walls of the building/structure are then built upon this "stem wall". This latter type of construction creates a 'heat bubble' so that the floor is not as subject to the expansion due to frost and secures the structures walls by being supported below the frost line.
Can I use OPC 43 grade cement in M20 grade concrete?
Yes. OPC 43 grade cement can be used to make M20 grade concrete.It can be used to make concrete up to M30 Grade.See related link.
What does a person use concrete polishing on?
Concrete polishing is a technique applied to the concrete slab foundation used as a base in most structures. By making use of the materials already present, this method reduces the ecological impact of construction and provides a striking, low-maintenance floor.
How much cubic meter of concrete will use for 1000sft slab?
m20 grade concrete per m3 load

How do you use slab in a sentence?
Just one more slab of bacon, please... That slab of concrete is sliding dangerously close to the edge of the cliff.

What are Advantage and disadvantage of In-situ concrete slab?
disadvantage: - require more time to construct compare to precast concrete slab -more on-site labor required - require formwork advantage: -most commonly use -do not require storage for material (e.g. precast concrete slab need place to store)
How thick of plywood to use to form a round concrete column?
Just use solatube
Which purpose you are using M30 grade concrete?
we use M30 grade concrete commercial slabs like shopping malls . college buildings
Can you pour concrete into a column and it not crack?
Yes but concrete is going to crack if it has too much stress. If it's a decorative column then use a 4000 mix. If it has a load on it you will have to figure how much weight is going to be on it.
What is causing the vinyl on concrete floor on grade to rise up in places whenever you do laundry or when it rains a lot?
More than likely the adhesive bond has been lost allowing the vinyl to separate from the concrete substrate. The "Floor on Grade" and "Rains a Lot" comments may indicate that you you have vapor emissions coming up through the slab where they condense under the floor covering and the water is compromising the adhesive that was applied to hold the flooring product in place. Not an uncommon occurrence in a slab on grade. A razor knife cut may actually reveal water under the covering. There are test that will give a relationship to pounds of water vapor per 100 Sq. ft. Anything over 3 pounds should not have had the vinyl installed. The fix is to remove the vinyl and adhesive and waterproof the slab. A penetrating sealer will fill the capillary voids in the concrete and prevent moisture from passing through. I use one that has low VOC stuff you can use inside and there are no problems with a bond of a flooring product after you waterproof the slab.

Can cinder be used in the sunken parts of a reinforced cement concrete slab?
Some contractors recommend and use cinder in the sunken parts of a reinforced cement concrete slab. Others caution against it in construction where a lot of seepage can occur because cinder can have a tendency to retain the water.
