Va pot spune din proprie experienta (am schimbat tot peretele dinspre protap, 80cm din podeaua fata si 40cm din podeaua spate) ca nu este o operatiune usoara deloc.
Necesita o multime de timp, manopera, materiale (unele speciale) si multa, multa rabdare !
Dupa cum stiti vechiul meu TEC l-am cumparat de la un coleg cu podeaua putreda si in spate si in fata.
Am demontat mobilierul din zonele cu probleme si am procedat la explorarea (ce mai am spart cu ciocanul) podelei pana cand am dat de material bun. Trebuie indepartat fara mila materialul afectat de apa, chiar daca asta inseamna extinderea lucrarii cu inca 30-40cm cat este distanta intre traverse.Numai dupa ce ai ajuns la structura buna poti incepe reconstructia.
De aici incep problemele, fiindca lemnul folosit trebuie sa fie neaparat din pin, uscat si fara crapaturi.
De asemeni placajul utilizat trebuie sa fie de maxim 5mm, dar destul de rezistent (am incercat la Bricostore ceva gen TEGO de 5mm dar era destul de prost, deoarece crapa la sarcina)
Am citit aceste lucruri pe site-uri americane de RV si chiar am vazut filmulete demonstrative.
Personal (deoarece rulota o voi folosi "stationar", am apelat la refacerea structurii din teava rectangulara usoara, imbinata prin sudare, placata la partea inferioara cu tabla Al.1,5mm, polistiren de 30mm intre straturi si o placa dintr-un material compozit pentru podea.
La toate imbinarile am folosit mastic special TEROSTAT dupa care am facut probe de etanseitate.
Sincer, a iesit o treaba de nota 10+, dar nu as mai repeta-o pentru nimeni si pentru nimic in lume.
Pentru cei care se descurca in Limba Engleza, sfaturi de la RV Doctor :
"if moisture happens to seep into the floor from any source, over time it will be necessary to replace the damaged sections. There is no quick fix for water induced damage - replacement is the only true solution. The good news is that in most cases, replacing damaged flooring can be performed by anyone with access to some power tools, some common sense, a little construction aptitude, a block of time and a generous amount of patience. Many RV owners can easily handle this chore. If, however, the affected area extends beneath wall partitions or cabinets, it is best to have a professional do the job. More often than not, though, damage is contained to a small area and repairs can be accomplished with relative ease. In most instances, floor damage will be quite evident by pulling back the carpeting or by removing the toilet, or by simply investigating a suspicious spot or stain. If the carpeting is still usable, carefully remove the entire section and safely store it until the flooring has been replaced. Keep in mind that RV floor construction methods vary from manufacturer to manufacturer, but the typical floor is usually bolted to a steel chassis after assembly. The top floor is usually applied in 4 x 8 sheets. The joists are typically twenty four inches or sixteen inches on center, but this dimension may vary between floor plans and categories of coaches. The size and positioning of the supports, cross beams and joists also vary depending on the weight and overall length of the RV. Quite often, the top flooring is attached to the beams with screws, nails, or staples so a visible line of fasteners will indicate where most supports are located. To replace the flooring without damaging the infra-structure (or the saw itself if the floor joists are made of steel), determine the exact floor thickness of the flooring material. Use any size hole saw attached to an electric drill motor to accomplish this. The larger the hole saw the better. Not only will a sample plug of the floor thickness be obtained, but a large hole saw will allow for an easy inspection of the inner floor area by using a flashlight and mirror. After determining the location of cross supports, joists or other blocking that may be in the sub-floor, lay out and mark the damaged piece to be removed. The cut lines should be directly over the center of a joist so that when the new piece is inserted, it will be supported by an existing joist or beam on at least two sides. Additional supports running the opposite direction may have to be added in order to accomplish this. Use a framing square to be sure the cut-out area will be straight and true. Use an electric circular saw to make the cuts. Set the depth of the cut to a little less than the measured floor thickness if the joists and supports are made of steel. If they are all wood, the saw blade depth should be set a little deeper than the thickness of the flooring. If the damaged area extends to the base of a cabinet it may be necessary to obtain an electric reciprocating saw that will enable a cut to be made closer to the obstructing cabinet. Once all the perimeter cuts have been made, remove any and all screws, staples or nails that may have been used to secure the original flooring to the supports. After all fasteners have been removed, lift or pry the damaged section out. After removing the damaged piece, examine the beams and sub-floor supports for rot or damage. If unaffected, proceed with the replacement. If there has been extended damage to wooden joists or supports, those rotted pieces must also be removed and replaced. Measure the lengths needed and cut new supports out of 2" x 2" or 2" x 4" lumber. Secure these to the available "good wood" inside the floor. (NOTE: In some cases it may be necessary to remove a larger section of plywood than was originally intended in order to secure sub-floor components to the existing, structurally sound framework. The goal is to have a solid support below the entire perimeter of the replacement piece prior to inserting it in place.) After the sub-floor components are in place, measure the entire cut out area and transfer the dimensions to the new piece of plywood of the same thickness as the existing flooring. Be sure to replace all wet, rotted or deteriorated insulation found inside the floor. Test the new piece for a proper fit, then glue the new section to the supports and secure it with the appropriate type of flathead screws. Be sure the screw heads are countersunk into the plywood so as not to interfere with the finished floor covering. Next, use a pre-mixed floor patch to fill in any voids or gaps around the perimeter of the replacement section. Then, sand smooth any rough areas or joints. Commercial grade floor patch is available at most hardware stores or home centers. Remember, severe water damage does not occur from one night of a leaky faucet. It happens gradually over a period of time. It is imperative that the source of the invading moisture be located and repaired accordingly. It would do little good to invest the time and materials needed to do a large floor repair and then not to repair the source of the water leak."
