Has a local authority or Government body like the UKs Environment Agency told you to expect floods due to heavy rain, rising river levels or high tide with strong winds or storms?. Flood Traps can do the job of the 10-14 x 15kg bags of sand you usually use to build a leaky wall like barrier in front of your robust door, and if belt and braces is your preference you can use both. 

Allups created a thin lightweight soft water activated seal pensioners or even a school aged child can fit. When wet the soft polymer gel instantly swells to fill the gaps between the door or window and its frame and so becomes an effective barrier to flood water entry. Boost your robust external door's seal so it can better resist even salt water floods keeping most surface water floods from entering.
Proven to work outstandingly well on test and in real life Flood Traps are easy to store, apply and throw away or bury once used. Probably the quickest, easiest, most affordable and most effective way to reduce flood water ingress and damage through doors and windows. Floodlock DIY flood traps help you keep contaminated flood water outdoors so you can get back to normal that much sooner. 
On a typical 76cm wide UK front door without a door step 3 lengths of flood traps can line the bottom and run 52cm (1ft 8") up the sides of the door. Two lengths would run 22cm up the door. 
Add the 13cm (5") to 30cm (1ft) height of your door step shown below and you can see
3 strips in a pack protect against 65cm (25") to 82 cm (32") = 10-14 sandbags
2 strips you could protect against 35cm (13") - 52cm (20") deep floods.
For protection against deeper floods and use with basement doors and garages more lengths can be used to suit your needs.
In independent laboratory tests Allups Floodlock Flood Traps stopped the water flow so it became stagnant as you can see below. 

In further tests the strips were seen not to leak for days working well as long as they remain wet and in position until the flood waters drain away.

Operations Director Paul Hendy at the independent Scottish Flood Forum reported Flood Traps were "tested & worked perfectly" when he saw how they kept water out of 4 homes in Glasgow. He went on to say they are an "Outstanding Success" and will bring benefit to many in need of an affordable alternative to sandbags.

Flood Traps kept contaminated overflowing drain water from entring through gaps around the doors on 4 properties in North Glasgow in November 2014 far better and more affordably than all previously tried solutions.

drain following a heavy downpour of rain but overflowing as is seen more and more commonly as our
climate changes.

How do Floodlock Flood Traps work?

The water activated soft water-proof gel quickly swells within each length of flood trap boosting your door's seal against flood water pressure, it continues to help keep water at bay until it dries out or until the door is opened. Here you can see how much the wet portion of the Flood Trap strip has swollen while the portion trapped in the door remained thin and dry.


This image shows just how little you would throw away, compared to several sandbags.

As flood water pressure presses on the soft swollen water proof gel strips they are squeezed into the gaps between the door and the frame.

Now instead of flood water pressure forcing water through gaps around your doors it helps Floodlock strips seal it out! 

Developed for Boston Borough Council who needs them to work against tidal sea and other salt water floods we devised a way for the strips to be pre-activated so they resist salt water. Folded each strip in half lengthwise and soak one half in a basin of tap water so that it swells up. Half of each length soaks up 1 litre of water. Trap the dry half of the trap tightly between the door and the frame as usual so it cannot be washed away with the strong tidal currents. Fitted this way the salt water cannot penetrate the gel, instead it helps create the seal against flood water ingress. Our video illustrates this well.

While kept dry, Floodlock Door Protection Strips can be stored in a draw for years, always ready to help you prepare for a flood whenever you need them.

Once used Floodlock strips can be buried or disposed of as household waste.

Each of the three strips in a pack absorbs 2 Litres of water, so can be used to soak up leaks, spills or flood incidents indoors and in hard to reach areas too!

Buy them now, before you need them and be ever ready to reduce water damage and recovery time whenever the next flood strikes - whatever the source.
