    A bit bigger concrete project (follow-up to 15.10.12)

    OK - I've finished the small concrete project (see 16.10.12), thanks to the advice of TD members and some physical effort by me. It's now time to consider a bit bigger project.

    Anybody got any idea:

    1. what thickness of concrete is required for a driveway?

    2. what's the going rate for Thais in the boondocks to do a driveway 30m x 2.4m (metal, other materials, and labour)?

    Any info greatly appreciated.

    as its so narrow, the edges are the places that will get the most loads and these will need to be made stronger to stop the weak edges cracking.
    fo light traffic (cars,bikes) a 100mm slab with a thickened edge of 150mm should be suffice as long as it is on proper compacted grade.
    however, for heavier loads i would recommend 150mm with a 200mm thickened edge. this will definately prevent cracking. also maybe make it wider if heavier traffic will be using it.

    6 inch thick, type 1 concrete, use a wire mesh (6 inch by 6 inch, should be fine) and place the mesh at least 2 inches from any surface

    Make sure you have at least 6 inches of a good base (rock/material) before laying the concrete

    You might consider sloping the concrete a bit so you don’t end up with standing water in the future

    Expansion joints every 20 feet (+ or -) and Construction joints at the end of each pour

    My driveway is about the same and 4 cm think. Labor was 3,000 baht and reddymix #1 concrete was 6,700 baht including delivery. Wire mesh was 300 baht

    How do Thais normally compact the sub grade, manually or with a motorised roller?

    You are suggesting a 6" slab with mesh 2" away from the surface. Is that the top, bottom or both?

    ^2 inches from the bottom would be easier. But just make sure itís 2 inches away from any surface (fresh water areas). 3 inches if youíre in coastal areas (salt water)
