I want to try to make some flood gates for our doors and they are very
expensive to buy. I want to use some sort of fixing that I can screw
into the wooden door frames permanently. These would have a thread in
the centre that I could use to bolt through, I imagine, external
plywood to create a tight fit as needed.

I have never seen anything like that, apart from rawlbolts which are
not designed for wood so far as I know. Does anyone know of such a
thing, or have a better suggestion? Many thanks.

I used aluminium square U channel, bolted to the side walls either side
of the doorway, with a hole from front to rear, near the top. Matching
holes in the flood board allowed me quickly to drop the board (cut from
an old scaffolding board) into the channels and hold it in place with
metal pegs. I used rubber seals along the bottom and sides of the board
to make it reasonably water tight. That produced a quick to deploy first
line of defence, which could be backed up with sand bags behind the
board as time permitted.

As floods can happen at night, when most of us are asleep, I also fitted
a float switch outside, linked to an under dome bell, in order to give
enough warning to get up and put the boards in place.

I don't have enough depth of brick to attach the channels to,
otherwise sounds great. We get about four hours warning from the
environment agency.

We did have 18" thick stone walls. Back when I did that, flood warnings
depended upon the Police coming around with a loudspeaker vehicle and
they didn't always have enough warning to get to everybody.

BTW don't forget that, in most properties, water can get under the floor
through air bricks, so they need protection too.

A length of steel pipe, larger ID than the OD of the drain, with a
flange on the bottom and a flexible seal on the flange? The weight of
the pipe should hold it in place while the water simply rises inside it.

Or through the drains. Downstairs loo? Floor drain in the scullary?

TBH fixing to the door frame seems a bit pointless to me. The water will
just find it's way between the frame and the wall. Don't think a tiny
bead of five year old silicon is going to keep it out...

Bits if ali U channel on the outside faces of the wall, solidy fixed and
witha full layer of sealant behind. Don't forget the horizontal at the
bottom of the opening. The board that slide down into this needs a
compliant seal of somesort arranged such that the weight of water
compresses it even harder. If there is a joint between boarsd that will
need a compliant seal as well and again idealy one where the weight of
water makes it seal harder. Not sure how one would arrange that.

Also see what your insurance company has to say about DIY flood gates. In
my view they should support you, as you are trying to reduce the losses
but knowing insurance comapnies if you don't use "approved" kit they'll
use it as hook to hang not paying out on.

If you have a downstairs toilet, that needs blocking too.

The stress of the impending flood will probably provide sufficient
material to do that.

But yes, it's where you see a lot of the nastier stuff come in.

It was self-adhesive and some sort of dense closed cell foam rubber.
Assuming they would have products for making things waterproof, I found
it by browsing around a local yacht chandlers.

TRADITIONAL evostik or urethane shoe glue works well.

Considering the consequences of failure, it's got to be mechanical

I think you'll need pumps as well. Ideally a sump with a float switch and pump running off a battery backed-up supply.

Round here (Cambridge) they put the water-tight gates in the boundary walls but then they have to make sure the water does not come in via the rainwater drains.

Or the sewers.

No but this intrigues me rather. How are you going to seal them and what
about water under the house itself.

I saw a diy floodgate on a door recently, made from U-channels bolted
to the frame, down which slotted a few horizontal 6x2 timbers. It
would have been trivial to make the gate in one piece, but I suspect
the piecemeal approach was to keep the weight of each part low, in
case the bloke wasn't available and his wife or kids had to do it.
I unrecall the method of tightening them down, but it wouldn't be
difficult to rawlbolt in a tie-down and fasten a ratchet strap.
Inside the door, under a grating, was a sump with a pump in it.

Of course, all this is for nought if the water simply comes in the
underfloor vents, or up through the floor or toilets, so pay attention
to that too.

Presumably the pump was a manual one - or did he have his own

I only saw an electric one in place, but it would have been trivial to
drop a manual one in. When it floods there, the power supply is
intact. The house has a history of flooding, being at the foot of a
hill and dodgy rainwater drains in the road unable to carry it all
away, so the owner was driven to take measures.

THey seem to require the door frame to be removed, though, as they fix
from the other side.
