Alternatives to sandbags?

Feb 12, 2014 10 Replies

I've spent the past few days helping neighbours who have suffered flooding. [Thankfully we have not suffered but it has been perilous close. Sadly we lost a wonderful weeping willow 10 days ago. About 20m high. Rootball is3m.] Local made sandbags to ground level doors and any air bricks (+ sealing wherever possible). Sandbags may have some effect but it's difficult to tell. Water will find its own level, be that through floors, walls or whatever. I was with the owner of a local company today and he has purchased a load of Floodsax. He gave me a box to try on a replacement basis. Never heard of them before and I wonder if anyone here has any experience of them. I would not expect them to be any more any better than sandbags. They seem V expensive and I presume they are one time only. This is not an advert in any way and I have no connection whatsoever with this product. I am just very interested to know of any experiences with this stuff and whether they might have an advantage over sandbags.

In the last 30 hours the water level here has fallen by about 400mm. Water level is still at least 500mm above normal. This afternoon our beloved borough council has dropped off a load of sand bags for the first time. Some residents locally have been flooded for more than two weeks with absolutely no assistance available from the council. Generally their phones spout an inane recording which basically says move upstairs or move from the area. This attitude is fairly normal. Why do they make sandbags available today? Do they know something we don't? Thanks, Nick.


Frequently, people overfill sand bags. they should only be about 3/4 full. Any more and they lose their ability to conform to fit tightly against other bags, walls etc.

I suspect their main advantage is that you can keep a lot of them on hand without needing much storage space.

Have you seen the forecast for Friday?

I guess the ability to store them stashed away in a garage/loft etc. is useful, and they can be deployed quicker than sandbags (if you include the filling time)

Same stuff that goes into disposable nappies I imagine

I wonder if cat litter would be any use...?

I think the idea is they are prefilled with an absorbent expanding material.

Yes, I realised that :-) I meant the time required to fill sandbags, if you don't have them filled already

AIUI sandbags provide support for the plastic sheeting which is the actual water barrier. Floodsacks wouldn't be heavy enough to do that till they had absorbed sufficient water. They sound like a bit of take-on to me, expensive and not reuseable

Probably not even then.

Sand is a lot heavier than water. These things will be about the same density. A sand bag will still slow the water flow after it's been topped, these would probably just wash away becoming almost weightless when under water.

Sorry, HOW MUCH???

indeed.

Still good to know that:-

"...the pioneering FloodSax®, which are all set to replace the traditiona l sandbags"

Je crois que non
