if i have a 60sqft of land with soil on top and i wan to do concrete with tiles on top for car to park.

for the correct method of doing,
brc and concrete -> wait for a week to dry -> tiling

or

brc and concrete -> next day -> tiling

which method is better and lasting?

obviously is wait for a week. concrete need curing

thanx a lot.
just thought of another question

i have a roof which is concrete top and it keeps on leaking. making a roof on top is not a solution as their is a water tank there. tried sika 107 or 109 but doesnt seems working. any method to solve it?

it would be stable?

sure stable if it is design by civil engineer. they depend on the load and design the footing size.

no idea sika 107 or 109. is it cementitious type of waterproofing? if yes then it should be fine. provided u lay the waterproofing thoroughly and correctly.

usually to be secure, roof slab will use membrane type of waterproofing (due to weather exposure) instead of cementitious. but of course it's expensive compare to cementitious waterproofing. cementitious is still acceptable though

ya cementious kind.but it will crack but not sure does it leak or not as i did around 3 layers on it.


wanted to find this kind of water proof material but it seems like hard to get.

after apply cementitious waterproofing u need to lay 1 screed as protective screed to the waterproofing. can't let it expose

lol
then a layer of cement on top of the cementious waterproof? a few layer of paint can?

just a 20mm thick cement sand screed will do. u do it on ur own? not expensive though. just 1 portion cement 3 sand mix enough

doing cement screed also smoothen ur surface ma.

ya.do on my own. thanx for tips. will try when free.

marine engineer oso ok wat

You apply cementitous water proofing on top of what?

Concrete?

Membrane?

Cement screed?

Tiles?

on top of concrete. concrete roof to be exact

No cement screed?

It supposed to have.

Now you need to apply water proofing to whole surface of your concrete roof than apply cement screed with good water flow.

How big is the roof?

even the original layer is only water proofing. bad developer anyway.
around 120sqft.

If only water proofing, then u need to apply water proofing material than only cement screed.

Beware of the gradient.

For this works i think you cant diy coz screeding need proper job.

i did the water proofing before this. but for screeding maybe need to ask someone to do it.but it wont be easy as the roof area is cramp with water tank and 2 light entrance thing.

i think best solution is having a roof there but till date dont have any idea for the roof

I have both Gauge 22 and Gauge 28 on hand. We proposed that we use 2 layer of Gauge 28 but architect somehow reluctant.
Gauge 22 is not cost efficient and very difficult to get the supplier to send to our site.

ic. then have to follow contract. the mesh sure have the spec mention the weight per m2 1. if gauge 28 comply to that spec, then u tell architect if he insist to use gauge 22 then have to pay for additional cost. if gauge 28 not comply to spec then even not cost efficient u also have to do.
