What is damp proof course in construction?
Damp proofing is waterproofing applied to foundation walls to prevent moisture from passing through the walls into interior spaces of a buildingDamp-Proof Course (DPC) - A horizontal barrier designed to resist moisture rising through the structure by capillary action - a phenomenon known as rising damp
What is the Concrete slab at entrance of building?
The slab is part of the overall foundation and footing system of the building. If it is outside, then it doesn't need to be water-proof or damp-proof. All interior foundation walls need to be water-proofed or damp-proofed depending on the hydrostatic pressure, found in the surrounding earth. Foundations and slabs-on-ground should be placed on good, compacted soil, or other acceptable aggregates. A solid slab should be a minimum 100mm thick.
Procedures in constructing a raft foundation?
Raft foundation is reinforced concrete slab that is supported on a compacted hardcore base that is bigger than the raft. The procedures in construction the foundation involves checking the soil properties, and making the edge of the raft stepped to make a toe so the outer leaf of the wall goes below ground. The slab is reinforced with steel, a radon barrier is added, and a damp proof course is put in.
What cement can i use on the face of the block?
It's called Surface Bonding Cement. It has chopped fiberglass in it. How to use it: Build a footer. Stack the block uo on the footer in the shape of the building. Get the block wet on one side of the wall. Trowel a 1/8" coat of Surface Bonding Cement on that side of the wall. Go to the other side of the wall, wet it and trowel a 1/8" coat of Surface Bonding Cement onto the wall. Keep it damp for the next week so it gets a chance to cure properly. Remember, concrete hardens by chemical reaction, not by drying out.

Full form of dpc in building?

What is the definition of DPC?
Damp proofing course. A damp-proof course (DPC) is a barrier through the structure by capillary action such as through a phenomenon known as rising damp. Rising damp is the effect of water rising from the ground into your property. The damp proof course may be horizontal or vertical.
What is a roof batten?
In the UK a roof batten is called a tile batten; this runs across the roof to fix the tiles too; this is 2 by 1 treated timber. Under this at right angles is nailed too the roof a counter batten; this allows an air gap under this again is laid a DPM/ [This means damp proof membrane].
How do you put sub floor down on concrete for a ceramic tile floor?
I would use a latex screed. like cement but with a latex binder, add water pour 5- 10mm on to the concrete and it self levels.Dries in about a day.Put a poylthene membrane down first if damp is a problem

Do you need damp proofing on a foundation wall if there is no basement or crawl space?
All structures would benefit from having damp proof foundation as damp would cause tearing in the foundation structure and weaken it over long time exposure.
Can concrete cement get mold in a damp basement?
Mold does not come from the concrete, it comes from mold spores that are normally in the air. Dampness faciliitate the growth of mold which comes in contact with concrete or any other material allowing mold to grow.
