Filling cracks in Concrete Floor

kevinknr · Postby **kevinknr** » February 12th, 2015, 11:57 am

I have quite a few cracks in the concrete flooring behind my house that I want to get filled. They vary in thickness, none wider than 4 mm.

Should I use sharp sand or building sand in the mixture? Also, what about gravel?

there is a concrete filler, or caulk

there are epoxy based fillers that come in small pails or in a dispenser similar to silicone that you use a gun to apply

Check FT Farfan

Sounds interesting .Will this stop grass from growing in these cracks?

I am not an engineer or builder but it is very hard to get concrete to join and already set surface . SCL has some products and there are various caulking items that may fit that purpose . On the local front some masons swear by poly V .

I remember seeing a rubber product from IRP that should also do the job .

There's a port injection system that you could use with the ETI-LV. You have to drill the concrete and insert the ports, then inject the epoxy.

Is that stuff ideal for sealing cracked plant pots as well shotta?

Hmm. I've got some pits on a surface, wondering if this would work or just redo the surface.

Even though it's been recast a couple times already.

I am presently looking for a efficient remedy for killing those 8 legged freaks who keep making incessant webs all over the window edges and under the eves

Tried peppermint oil but...

Just use a broom and sweep away the webs when you're cleaning. If you didn't have spiders you would notice very soon just how many insects they keep in check in your house. Unless you're talking about an excess invasion of spiders?

I clean webs weekly and they just keep making more , I know they maintain the insect population but not in my house. Haha.....

Try PC CONCRETE very effective. Sold at Bhagwansighns

i've used regular thinset for tiling to fill some cracks in concrete. worked good so far for me

some of those products may be expensive and possibly not intended for small back yard household cracks. might want to consider plaster mix with d fibre business or chip d crack, make it bigger so whatever yuh mix and fill will have enough surface area to contact and hold strong. poly V with a strong sand mix might be good too.

kevinknr · Postby **kevinknr** » February 18th, 2015, 1:25 pm

Thanks all. I found out that poly v was used before but the cracks opened up again. Thinking of trying an epoxy filler as suggested by duane and mark.

pugboy · Postby **pugboy** » February 18th, 2015, 2:23 pm

keep in mind if the slab was not properly setup with steel etc to reinforce and keep together

the natural expansion/contraction could very likely make same cracks reappear even after filling with epoxy.

York · Postby **York** » February 18th, 2015, 7:24 pm

Concrete doesn't join and yuh cyar glue it together. Steel reinforcement and prior compaction if not properly done...yuh will have to live with cracks and just fill them as they appear or widen.

Ok. So i finally got around to buying the PC concrete. Got a tube for $150 in a Couva Hardware. A few dollars cheaper than Bhagwansinghs.

I may need to buy more as the cracks have significantly widened. My fault for taking so long to patch them.

Anyway, most hardwares have something called Plasti Filler or something like that. Price ranges from 700-800 a bag. Supposed to mix with poly v and fill cracks. Anyone have experience with plasti filler? Is it any good?
