Lightweight Concrete Floor Over Plywood
Does anyone out there have any information about how we can do a finished concrete floor on a plywood subfl.
Lightweight concrete floor over plywood. The original plan was to do a 2 concrete pour over our radiant heat system as recommended by our builder. We are building a 2 story condominium complex with concrete slab on grade. When installed correctly your concrete over plywood floor will not permit moisture through will not warp or buckle and will come with all the benefits of concrete in an easy to care for floor. We recommend applying param 5500 at a minimum thickness of 3 8 1 2 is preferred to.
Metal lath stapled over plywood substrate. Should i put a membrane between the concrete topping over plywood subfloor we are going to be pouring a 1 5 concrete slab overtop of a plywood floor to encase our in floor heating pipes. The reduced quantity of concrete and steel reinforcement offsets the marginally higher cost of lightweight concrete floor systems. Duraamen s param 5500 goes on thin in a 3 8 to 1 2 thick application.
Not only is it. Since lightweight concrete is more prone to cracking than traditional concrete it can lead to problems when used with hardwood floors. We are hearing a lot of concerns from concrete contractors about pouring that thin. These floors are constructed for different purposes but the reduction of dead loads on the structure is.
For locations where carpet is going to be installed lightweight concrete is an acceptable material for building a subfloor. Lots of guys pour directly ontop of the plywood but i wanted to find out if anyone has heard of putting like a building paper down first. The installation of calcium aluminate cement based self leveling concrete param 5500 along with expanded metal lath for reinforcement is a successful fast track method to convert a plywood subfloor into a beautiful concrete floor. For the second story a foamed type of lightweight concrete is being used over plywood for sound absorption between floors.
It lays down ultra flat.
