Good afternoon Has anyone heard of "smart tray" cavity trays which claim to be able to be installed through a single cut in the wall rather than removing 2 levels of brick? There is a website under the name "cavity tray man" Too good to be true?
You asked if they were too good to be true and I said yes. Anything more specific you'd like to know?
Maybe abit more detail? How you know? Why are they too good to be true? I appreciate the response, but I'm trying to decide if they are worth looking into as no builder will even quote to install cavity trays so I was hoping for abit more detail in the specifics of what makes them good/bad etc.
I fitted them on an NHBC warranty job but they didn't work, water still leaked down the cavity. Trouble is you can't see what has gone wrong or why they weren't working. Ended up fitting "normal" ones where you can actually see what you are doing.
When they say you can install them in one cut do they mean without removing a brick? I'm kind of at the stage where I'm thinking surely it's worth a go. No one else is willing to remove bricks and fit normal cavity trays. I'm assuming it's too much hassle and not worth the effort for them.
Nope never tried them and still only half fixed my issue. Have a cavity wall above an extension which is missing cavity trays. it's basically no better that a garage wall (half a brick thick) and the flashing would leak which I have repaired and have had no problems since. To my knowledge i have had no penetrating damp through the single skin even during very heavy rainfalls. Seems my problem was the flashing joint.
