Monocouche below ground

[Ianspreader]

I have just rendered a double garage with room above with webber pral m and now the client has asked me to do his garden walls, they are earth retaining so come up with the idea of strong water proff sand and cement mix scratch bead then monocouche, or would it be ok just to go straight on or any other ideas cheers ian

needs tanking or a physical membrane on the retaining side, normal water proofer won't withstand the hydrostatic forces imposed on it

How about a decent 3 in 1 SBR mix?

Stick some 'weep holes' in aswell.

parex reccomend using lanko latex in first coat, i did one 3 meters below ground last year with no problems..... YET

so effectively creating a tanked system, which is what has been mentioned, but i doubt it would withstand a reasonably high head of pressure

Warrior, i;m guessing that the Lanko is simply another Styrene Butadiene Copolymer. Along wiht all the others.

Interestingly enough, I once demonstrated to an architect that a mortar ,modified with Cementone Integral No2 withstood a greater head of pressure than a Sika waterproofer.

or ... their thechnical depts did.

Nothing to do with this realy but according to the free building mag you get in merchants Cementone bonding agent is PVA based, ime not sure WBA is or the many others ?
