It’s a little late, but I started the waterproofing terraces, covered with OSB-3.
I was looking for a solution for a long time and how to do it properly taking into account the "appearance" of terraces.
The informed decision was prompted by the specialists EKSO (for which a special thank to them):
1. I shuted all the seams with a sealant Gipersil-25LM.
2. I covered the entire surface of the liquid polyurethane membrane “Giperdesmo” with an accelerator of a polymerization in 2 layers with an interval of a day (It’s not easy to lay the first layer when it's cold). A consumption in fact is slightly less than 14 kg per 10 sqm in two layers.
3. I poured a sand on the second wet layer (to improve the adhesion to the future screed downhill).
Then I plan to fill the tie with a slope of about 1.5%. I’m planning to add in a solution a fiber and aplasticizer “Porolit-LP”. This plasticizer increases the service life of a concrete in the open air, due to the fact that it does not saturate them with a water from precipitations. Accordingly, the number of cycles of freezing, which it maintains significantly increases. I will use again “Giperdesmo” in two layers with the sand and will lay the floor tiles.
But there are still plans that frosts can violate. Now, the forecast is Ok., and then we will see ...
At the same time, I cut the lawn for winter, pruned the trees and collected a cauliflower, which stood at 5 degrees below zero!
On Saturday, we made a coupler on the terrace.
1. We put up lighthouses and covered the perimeter by the board.
2. We filled a part, then rested a little bit and refiled.
The solution was made in the same proportion:
1 bucket of cement M400 (a half of a sack).
3.5 buckets of a river sand.
6 grams of “Porolit” (a plasticizer).
1 microfiber (a calculation of 0.9 kg per 1 cubic meter of solution).
the water was looked at a plasticity.
We decided not to reinforce with rids, I believe that 22 mm OSB will not get out, moreover I will lay tiles.
Fibers were added last in the insolution, then we stirred for 2-3 minutes in the mixer. The distribution of fibers in the amount is staggering!
